    Description: The invention relates to a swivel gear for connecting a drive motor to a swivel-driven swivel component, as well as a swivel drive system with such a swivel gear and a peeling centrifuge and a filter system with such a swivel drive system.
    In peeler centrifuges e.g. a peeling knife provided therein can be moved by means of a hydraulic drive against a solid material layer remaining in the peeling centrifuge. Such a peeling centrifuge is e.g. known from DE 3 904 358 A1. A hydraulic drive can be unfavorable in terms of leakage and high energy consumption.
    The invention provides a swivel gear which enables a component to be swiveled, such as e.g. to drive a peeling knife of a peeling centrifuge in an energetically favorable manner. Furthermore, the invention provides a swivel drive system, which is equipped with such a gear, as well as a filter system and a peeler centrifuge, which are equipped with such a swivel drive system.
    The invention provides a swivel gear for connecting a drive motor to a swivel-driven swivel component, which swivel gear has a gear housing, an input shaft which is rotatably and axially fixedly mounted on the gear housing and to which a drive motor can be connected, an output shaft which is on the gear housing is rotatably and axially fixed and which is arranged in alignment with the input shaft and to which the swivel component can be connected, and a gear mechanism, of which the input shaft and the output shaft are connected to one another and which has: a thrust thread mechanism with a thrust piece which is rotationally fixed relative to the gear housing is attached and which is in a thrust thread engagement with the input shaft, so that the thrust piece correspondingly axially back and forth by a back and forth rotation of the input shaft due to the thrust thread engagement along the input shaft can be supported, a swivel thread mechanism with a swivel piece which is in a swivel thread engagement with the output shaft, so that the output shaft can be rotated correspondingly back and forth by an axial back and forth movement of the swivel piece along the output shaft due to the swivel thread engagement, and a coupling device, by means of which the thrust piece and the swivel piece are connected to one another in an axially fixed manner, so that the swivel piece can always be displaced axially back and forth in a corresponding manner together with the thrust piece by means of the back and forth rotation of the input shaft, in order thereby to perform the swivel thread engagement to drive the output shaft correspondingly back and forth.
    The two thread engagements, i.e. the push and the swivel thread engagement allow a very high stability with regard to the prevention of system vibrations with regard to an undesired torsional vibration / torsional vibration of the output shaft superimposed on the actually desired rotational movement of the output shaft or a swivel motion vibration superimposed on the actually desired swivel movement of the component to be pivoted / -Vibration, since the thread engagements per se can be provided with little movement play and can also be provided with a sufficiently large transmission ratio, so that a drive motor, which is connected to the input shaft of the swivel gear, only has to deliver a relatively low drive torque and / or holding torque to perform the required swivel movement of the component safely and with low vibrations.
    Thus, a drive system equipped with the swivel gear according to the invention can e.g. get by without a hydraulic drive motor.
    The ratio of thread pitch to thread diameter in thrust thread engagement is e.g. smaller than with swivel thread engagement.
    Thrust thread engagement is e.g. in the form of a regular thread engagement, which e.g. has a ratio of thread pitch to (nominal) thread diameter of less than approximately 0.5, or a fine thread engagement in which the ratio of thread pitch to (nominal) thread diameter is even smaller than in the case of standard thread engagement, or one Ball screw engagement, which one, for example has a ratio of thread pitch to thread diameter of less than approximately 0.5, or a planetary thread engagement which, e.g. has a ratio of thread pitch to thread diameter of less than approximately 0.5, or a roller thread engagement which, e.g. has a thread pitch to thread diameter ratio of less than about 0.5.
    The ratio of 0.5 of thread pitch to thread diameter corresponds approximately to a (with regard to the thread production relevant) roll angle of approximately 9.2 °.
    The swivel thread engagement can e.g. be designed in the form of a high-helix engagement, which, e.g. the ratio of thread pitch to thread diameter (thread pitch / thread diameter) of the high-helix engagement is at least about 0.5.
    The ratio of thread pitch to thread diameter is in the swivel thread engagement e.g. larger than with thrust thread engagement. The ratio of thread pitch to thread diameter is greater with steep thread engagement than with standard thread engagement.
    The thrust piece is e.g. formed as a thrust bushing, which is arranged on the input shaft and (on the input shaft (by the back and forth rotation of the input shaft)) axially movable back and forth.
    CH 709 622 B1 Furthermore, the swivel piece is e.g. formed as a swivel bushing, which is arranged on the output shaft and (on the output shaft (due to the axial back-and-forth movement of the thrust bushing with which the swivel bushing is axially connected)) can be moved axially back and forth (to thereby move the output shaft over to force the swivel thread engagement to a rotational movement (about the longitudinal axis) corresponding to the axial to-and-fro movement).
    The thrust thread mechanism has e.g. to an input shaft external thread which is formed on the input shaft and with which the thrust bushing is in thrust thread engagement, the thrust bushing for this purpose e.g. is provided with a thrust bushing internal thread, which engages in the external shaft of the input shaft (i.e. the thrust thread engagement is formed in this case by the engagement between the internal thrust bushing thread and the external thread on the input shaft), or a recirculating ball mechanism with balls which can be traced back in the thrust bushing , which engage in the input shaft external thread (ie, the thrust thread engagement is formed in this case by the engagement between the balls and the input shaft external thread), or a planetary mechanism with planets rotatably mounted in the thrust bushing which engage in the input shaft external thread engage (ie, the thrust thread engagement is in this case formed by the engagement between the planet and the input shaft external thread), or a roller circulation mechanism with rollers which are traceably mounted in the thrust bushing and which engage in the input shaft external thread (ie, the thrust Thread engagement we d in this case formed by the engagement between the rollers and the input shaft external thread).
    The pivot thread mechanism has e.g. on an output shaft external thread which is formed on the output shaft and with which the swivel bushing is in swivel thread engagement, the swivel bushing being used for this purpose e.g. is provided with a swivel bushing internal thread, which engages in the output shaft external thread (ie, the swivel thread engagement is formed in this case by the engagement between the swivel bushing internal thread and the output shaft external thread), or a recirculating ball mechanism is also traceable in the swivel bushing has balls which engage in the output shaft external thread (ie, the swivel thread engagement is formed in this case by the engagement between the balls and the output shaft external thread), or a planetary mechanism with rotatably mounted planet in the swivel bushing, which in the Engage the output shaft external thread (i.e., the swivel thread engagement is formed in this case by the engagement between the planet and the output shaft external thread), or has a roller circulation mechanism with rollers which are traceably mounted in the swivel bushing and which engage in the output shaft external thread (i.e. , the In this case, swivel thread engagement is formed by the engagement between the rollers and the output shaft external thread).
    The pivot piece is e.g. (in turn) mounted in a rotationally fixed manner relative to the gearbox housing, the swivel piece optionally being connected directly to the gearbox housing in a rotationally fixed manner, optionally by means of a feather key and / or a spline connection. Here, e.g. the thrust piece is connected in a rotationally fixed manner to the swivel piece by means of the coupling device in order to mount the thrust piece in a rotationally fixed manner relative to the gear housing. That is, because the swivel piece is in turn attached in a rotationally fixed manner, the thrust piece connected to the swivel piece in a rotationally fixed manner is fixed in a rotationally fixed manner or indirectly in a rotationally fixed manner on the housing via the swivel piece.
    The pivot piece can e.g. also be rotatably (but nevertheless axially fixed) connected to the thrust piece and can e.g. be connected to the gearbox via an additional swivel thread engagement, so that the swivel piece within the scope of its axial back and forth movement (which is caused by the rotary movement of the input shaft via the thrust thread engagement) by means of the additional swivel thread engagement (with the gearbox housing) undergoes a corresponding back-and-forth rotation, which (correspondingly) is transmitted via the swivel thread engagement as an additional back-and-forth rotation to the output shaft, which (additional back-and-forth rotation) adds to the back and forth rotation of the output shaft (to a total back and forth rotation) which (back and forth rotation of the output shaft) the output shaft (alone) by the axial back and forth Movement of the swivel piece along the output shaft is experienced due to the swivel thread engagement.
    The additional swivel thread engagement is e.g. is designed in the form of a steep-thread engagement, the ratio of thread pitch to thread diameter (thread pitch / thread diameter) of this steep-thread engagement optionally being at least approximately 0.5. The additional thread engagement can e.g. be formed by a swivel bushing external thread formed on the outside of the swivel bushing and an internal threading on the gearbox housing formed on the inside which is in engagement with the swivel bushing external thread.
    The gear housing is e.g. formed with a front axial stop and a rear axial stop, of which the axial movement of the thrust piece is axially limited, the axial distance between the front axial stop and the rear axial stop optionally being such that the output shaft has a maximum swivel angle or maximum rotation angle of less than or equal to 360 ° or has less than 360 °.
    The ratio of the thread pitch of the thrust thread engagement to the thread pitch of the swivel thread engagement is e.g. less than or equal to about 0.1, and is optionally in the range of about 0.01 to about 0.034. The ratio of the thread pitch of the thrust thread engagement to the thread pitch of the additional swivel thread engagement is e.g. less than or equal to about 0.1, and is optionally in the range of about 0.01 to about 0.034. These relationships can e.g. have advantages in terms of vibration / vibration stability and swivel range.
    CH 709 622 B1 In the swivel gearbox, the input shaft and the output shaft can be the only components which protrude from the gearbox housing, the gearbox housing being otherwise completely sealed or encapsulated. Since the input shaft and the output shaft can only be rotated but are axially fixed, the housing can be securely sealed at the exit points of the input shaft and the input shaft. The thread engagements can thus be lubricated securely by the gearbox housing, e.g. be provided with grease lubrication. This means that the grease lubrication or grease can e.g. simply inserted into the housing and always remaining in the gear housing (during a certain operating time) and encapsulated by the gear housing.
    A swivel drive system for the swivel drive of a swivel component according to the invention comprises: a drive motor which has a drive shaft and a swivel gear as disclosed in this application which is connected to the drive motor, the drive shaft optionally being arranged coaxially with the input shaft, the drive motor optionally being a pneumatic motor.
    The arrangement coaxial with the input shaft enables a simple, direct connection (i.e. e.g. without an intermediate gear element, such as a chain, a belt or a toothed wheel) between the drive shaft and the input shaft, which e.g. by means of a key or a spline connection in a low-clearance manner or e.g. can be achieved in a play-free manner by means of a wedge connection. Such a direct connection is less sensitive to undesired system vibrations / system vibrations.
    The pneumatic motor can have advantages in terms of immunity to blocking because of the compressibility of the pneumatic, e.g. When the axial (end stops) are reached, the pneumatic motor can simply continue to be driven without the system being overloaded. The swivel gear also makes it possible to use a small pneumatic or air working pressure, which, for example, is less than or equal to approximately 10 bar can be less than or equal to approximately 6 bar, thereby keeping the energy requirement low.
    The drive motor can also be formed by a hand crank, which allows manual drive, or can be formed by an electric motor, such as e.g. an asynchronous motor and / or a servo motor and / or a stepper motor. In order to avoid overloading the electric motor when an axial end stop is reached, electronic control can be provided which switches the electric motor off, e.g. when a predetermined maximum torque value is reached.
    A control device can also be provided which detects the pivoting movement of the component and / or the axial movement of the thrust piece and / or the rotational movement of the input shaft and / or the output shaft and which on the basis of the detected movement path (for example pivoting and / or Axial and / or rotary movement) the drive motor to reach the or, for example Stopping at the desired movement path ends controls.
    The swivel gear according to the invention and / or the swivel drive system according to the invention can be used, for example, for pivoting driving of a locking mechanism of a clamping ring of a peeling centrifuge, for pivoting driving of a peeling device of a pharmaceutical centrifuge (all sizes) and / or a classic peeling centrifuge eg a size of 160 Hz and / or for pivoting driving of door peeling pipes, siphon peeling pipes and / or filling control controllers.
    The invention provides e.g. furthermore, a peeling centrifuge with a centrifuge housing, which has a receiving space and which is optionally designed as a closed centrifuge housing and also optionally at least in two parts with a housing pot part and a housing cover part, a centrifugal drum which is arranged in the receiving space and an interior and a the Has inner delimiting inner peripheral surface, a peeling knife which is arranged in the interior of the centrifugal drum and is provided for peeling off a solid material layer deposited on the inner circumferential surface, a knife carrier to which the peeling knife is fastened and which is pivotably mounted relative to the centrifugal drum in order to move the knife carrier by swiveling the knife carrier To be able to move the peeling knife correspondingly against the deposited solid material layer and away therefrom, and a swivel drive system as disclosed in this application, the output shaft of the swivel gear being connected to the knife door äger is connected (which, e.g. together with the peeling knife attached to it, which represents the pivoting component to be pivotally driven) for pivotally driving the knife carrier, the pivoting drive system optionally being attached or supported on the centrifuge housing and also optionally on the housing cover part of the centrifuge housing, e.g. is exclusively attached to it (or supported by it), the drive motor optionally being arranged outside the receiving space, and the swivel gear optionally being arranged outside the receiving space.
    The invention provides e.g. Furthermore, a filter system, which is optionally a filter centrifuge, is ready with a filter system housing that has a first housing part and a second housing part, a filter device that is optionally designed as a centrifugal drum and that is arranged in the filter system housing and by means of which a substance component from one of the filter devices is supplied Source material can be filtered out, a housing connecting device, by means of which the first housing part can be releasably connected to the second housing part, the housing connecting device having a clamping ring which has a first and a second clamping ring end, which are connected to one another via a clamping mechanism , the tensioning mechanism being a pivotable tensioning lever
    CH 709 622 B1, and a swivel drive system as disclosed in this application, the output shaft being connected to the tensioning lever for pivotally driving the tensioning lever.
    The tensioning mechanism can e.g. as described in DE 4 419 302 C1, the disclosure of which is necessary to explain the clamping mechanism, e.g. from column 1, line 44 to column 2, line 57 of DE 4 419 302 C1, is included here.
    The invention is illustrated below using preferred exemplary embodiments with reference to the drawings. In the drawings:
    Fig. 1 is a sectional view of a swivel gear according to an embodiment of the invention and
    Fig. 2 is a schematic sectional view of a filter centrifuge according to an embodiment of the invention.
    In the drawings, the same reference symbols are used across the figures for the same components.
    In Fig. 1 is a swivel gear 2 (see for example also Fig. 2) for connecting a drive motor 4 (see for example Fig. 2) with a swivel-driven swivel component 6 (see for example Fig. 2) according to an embodiment of the invention in a sectional view (longitudinal sectional view), the swivel gear 2 having: a gear housing 8, an input shaft 10 (see, for example, also FIG. 2), which is rotatably and axially fixed on the gear housing 8 (ie, the input shaft 10 is rotatable with respect to the gear housing 8 and axially fixed) and to which the drive motor 4 (see, for example, FIG. 2) can be connected, and an output shaft 12 (see, for example, also FIG. 2), which is rotatably and axially fixed on the gear housing 8 (ie, the output shaft 12 is in relation to Gearbox housing 8 rotatable and axially fixed) and which is aligned or coaxial to the input shaft 10 and to which the pivot member 6 (see for example Fig. 2) can be connected. The input shaft 10 and the output shaft 12 are arranged directly one behind the other, as seen in their axial direction.
    The gear housing 8 is formed here as a completely encapsulated and sealed housing, of which only the input shaft 10 with a free end or input shaft connection end 11 and the output shaft 12 with a free end or output shaft connection end 13 in a sealed manner stand out.
    1 furthermore has a gear mechanism 20, of which the input shaft 10 and the output shaft 12 are connected to one another and which comprises: a thrust thread mechanism 22 with a thrust piece 24 designed as a thrust bushing, which is rotationally fixed relative to the gear housing 8 is attached and which is in a thrust thread engagement 26 with the input shaft 8, so that the thrust piece 24 by a back and forth rotation of the input shaft 10 (about its longitudinal axis) (driven by the drive motor 4) due to the thrust thread engagement 26 along or here on the input shaft 10 corresponding axially back and forth is displaceable or is moved back and forth.
    The gear mechanism 20 also has a swivel thread mechanism 30 with a swivel piece designed as a swivel sleeve 32, which is in a swivel thread engagement 34 with the output shaft 12, so that the output shaft 12 by an axial back and forth movement of the swivel piece 32 along or on the output shaft 12 due to the pivot thread engagement 34 is rotatable back and forth (about its longitudinal axis).
    The gear mechanism 20 also has a coupling device 40, by means of which the thrust piece 24 and the swivel piece 32 are axially fixed to one another, so that the swivel piece 32 is always together with the thrust piece 24 by means of the back and forth rotation of the input shaft 10 ( driven by the drive motor 4) correspondingly axially (along the output shaft 12) to and fro. In the embodiment of FIG. 1, the swivel piece or the swivel bushing 32 extends integrally or in one piece from on the output shaft 12 to over or over part of the input shaft 10 and over the thrust piece or the push bushing 24 or over one Part of the thrust piece 24. The coupling device 40 also has an external coupling thread 42 formed on the connecting piece or the thrust bushing 24 and an internal coupling thread 44 formed on an inner peripheral surface of the swivel bushing 32, which is in coupling thread engagement with the external coupling thread 42 , Furthermore, the coupling device 40 has a collar 46 integrally formed on the thrust piece or on the thrust bushing 24, against which the swivel piece or the swivel bushing 32 is firmly screwed by means of the coupling thread engagement with an axial end face facing the input shaft 10, as a result of which the swivel piece or the swivel bush 32 and the thrust piece or the push bush 24 are axially fixed and, due to the tension achieved by means of the screw connection against the collar 46, are also fastened to one another in a sufficiently rotationally fixed manner.
    In the embodiment of Fig. 1, the thrust thread mechanism 22 has an input shaft external thread 50 which is formed on the input shaft 10 and with which the thrust piece or here the thrust bushing 24 via a thrust bushing internal thread 52, which is on an inner peripheral surface of the thrust piece or the thrust bush 24 is formed in the thrust thread engagement 26. The swivel thread mechanism 30 has an output shaft external thread 60 which is formed on the output shaft 12 and with which the swivel piece or here the swivel bushing 32 via a swivel bushing internal thread 62 which is formed on an inner peripheral surface of the swivel piece or the swivel bushing 32 in the swivel thread engagement 34 stands.
    CH 709 622 B1 In the embodiment of FIG. 1, the swivel thread engagement 34 is designed in the form of a steep thread engagement. That is, (both) the swivel bushing internal thread 62 and the output shaft external thread 60 are designed as steep threads, with the ratio of thread pitch to thread diameter (thread pitch / thread diameter) of the steep thread engagement being at least approximately 0.5. The thrust thread engagement 26 is in the form e.g. a regular thread engagement (metric thread) or a fine thread engagement. That is, (both) the inner bushing thread 52 and the input shaft outer thread 50 are designed as standard or fine threads, the ratio of thread pitch to thread diameter (thread pitch / thread diameter) of the thrust thread engagement 26 e.g. is smaller than the corresponding ratio for the swivel thread engagement 34 and e.g. is less than about 0.5.
    The pivot piece or the pivot bushing 32 is rotatably attached via a key 70 with little play in the circumferential direction or almost free of play directly on the gear housing 8 or on an inner surface of the gear housing 8, the key 70 being formed in a gear housing 8 Longitudinal groove 72 (seen in the circumferential direction with little or almost no play) is received, which runs parallel to the longitudinal axes of the input shaft 10 and the output shaft 12 and which is longer than the key 70, so that the key 70 is guided in the longitudinal groove 72 along the longitudinal groove 72 can move axially back and forth, whereby the corresponding axial back and forth movements of the thrust bushing 24 and the swivel bushing 32 are axially guided by the engagement between the key 70 in the longitudinal groove 72.
    From the gear housing 8, a first axial stop or axial end stop 80 and an axially spaced second axial stop or axial end stop 82 are formed in the housing interior, which are each designed in the form of an inner axial shoulder. The combination of a tightly coupled thrust piece / thrust bush 24 and swivel piece / swivel bush 32 is limited in its axial movement path by the first and second axial stop 80, 82, the thrust piece or the push bush 24 having one end face axially abutting against the first axial stop 80 or abuts and the pivot piece or the pivot bushing 32 can abut or abut against the second axial stop 83 with an axial shoulder.
    In operation, the input shaft 10 is rotated back and forth by the drive motor 4 connected to it, as a result of which the thrust bushing 24 is attached in a rotationally fixed manner relative to the transmission housing 8 and because of its thrust thread engagement 26 with the input shaft 10 on the input shaft 10 and along the Input shaft 10 is moved axially back and forth. As a result, the swivel bush 32 which is axially fixedly coupled to the thrust bush 24 is in turn correspondingly moved axially back and forth, as a result of which the output shaft 13, owing to its swivel thread engagement 34 with the swivel bush 32 and due to its bearing which is axially fixed relative to the gear housing 8, corresponds to the axial back and forth Movement of the swivel bushing 32 is reciprocated in order to correspondingly pivot a component 6 (see FIG. 2) connected to the output shaft 13 in a rotationally fixed manner.
    In an alternative, not shown, the swivel bushing or the swivel piece 32 is not attached in a rotationally fixed manner to the transmission housing 8 by means of a feather key 70, but instead, e.g. connected to the gear housing 8 by means of a thread engagement replacing the parallel key groove engagement, which represents an additional swivel thread engagement which e.g. is designed as a steep thread engagement, the swivel bushing or swivel piece 32 then e.g. is rotatably arranged relative to the push piece or the push bushing 24, and the push piece or the push bushing 24 not e.g. direct, e.g. by means of a feather key, with which the gear housing 8 is coupled in a rotationally fixed manner.
    The additional swivel thread engagement, not shown, causes the swivel bushing or the swivel piece 32, when it is moved axially back and forth by the thrust piece or the push bushing 24, to undergo an (additional) back and forth rotation, which coincides with the back and forth rotation of the output shaft 12, which back and forth movement occurs due to the swivel thread engagement 34 in combination with the axial back and forth movement of the swivel piece or the swivel bushing 32 is such that the output shaft 12 undergoes a total back-and-forth rotation from the aforementioned back-and-forth rotation and the additional back-and-forth rotation.

The centrifugal drum 230 has a (drum) interior 240 and an inner peripheral surface 244 delimiting the (drum) interior 240, on or on which a filter medium 246, e.g. a sieve fabric is arranged.
    The peeling centrifuge 200 also has a peeling knife 260, which is arranged in the interior 240 of the centrifugal drum 230 and is provided for peeling a solid material layer 264 deposited on the inner peripheral surface 244, and a knife carrier 270, to which the peeling knife 260 is fastened and which is pivotably mounted relative to the centrifugal drum 230 and relative to the centrifuge housing 210 by means of a rotary bearing 265 (for example by
    CH 709 622 B1 a radial distance from the axis of rotation of the centrifugal drum 230 and e.g. at least essentially parallel or parallel swivel axis), in order to be able to move the peeling knife 260 correspondingly against and towards the deposited solid material layer 264 and away from it by means of swiveling the knife carrier 270, and a swivel drive system 300 for the swiveling drive / driving of a the swivel component 6, which is formed here by the knife carrier 270 with or without the peeling knife 260 attached thereto, the swivel drive system 300 having the drive motor 4, which has a motor output shaft or drive shaft 302, and a swivel gear 2, which, for example how the swivel gear 2 described with reference to FIG. 1 is constructed and which is connected to the drive motor 4.
    The output shaft 12 of the swivel gear 2 is rotatably connected to the knife carrier 270 for pivotally driving the knife carrier 270. The swivel drive system 300 is arranged in the embodiment of FIG. 2 on the centrifuge housing 210 outside its receiving space 220, in which case it is is arranged outside the receiving space 210. That is, the drive motor 4 is here arranged completely outside the receiving space 220 of the centrifuge housing 210, and the swivel gear 2 is arranged at least substantially or completely outside the receiving space 220 of the centrifuge housing 210. Furthermore, the drive system 300 is attached to the housing cover part 222 of the centrifuge housing 210, or is attached to or supported on it (for example, only attached / attached / supported thereon).
    The housing cover part 222 and the housing pot part 224 can e.g. be releasably attached to one another by means of the tension ring described in DE 4 410 302 C1, which has a tensioning mechanism, e.g. with a tensioning lever, which in turn is driven or actuated by a drive system (pivoting) that is at least substantially identical to the drive system 300 (e.g.).
    In the embodiment of Fig. 2, the drive shaft 302 of the drive motor 4, the input shaft 10 of the swivel gear 2 and the output shaft 12 of the swivel gear 2 are aligned or coaxial, the input shaft 10 coaxially in a central recess in the drive shaft 302 engages and is rotatably fixed in this recess, for example by means of a feather key connection or a spline connection or a spline connection, and wherein the output shaft 12 engages coaxially in a central recess of a cantilever arm 304 of the knife carrier 260 and is fixed in a rotationally fixed manner in this recess, e.g. by means of a key connection or a spline connection or a spline connection. The cantilever arm 304 of the knife carrier 260 in turn extends in alignment or coaxially with the input shaft 10 and the output shaft 12 of the swivel gear and thus also with the drive shaft 302 of the drive motor 4.
    The drive motor 4 is e.g. a pneumatic motor which can be supplied with compressed air via a pneumatic line and can be (pneumatically) driven by means of the compressed air. The drive motor 4 can also e.g. be designed as an electric motor.
    The filter centrifuge 200 also has various other devices, such as e.g. a solid discharge device 400 for discharging the solid material or solid material 264 peeled off from the peeling knife 260 from the centrifuge housing 210, a washing device 420 with washing nozzles for applying washing liquid to the solid material or solid material 264 adhering to the drum inner peripheral surface 244, a feed device 450 for feeding of the material / substance mixture to be filtered (eg suspension) into the centrifugal drum 230 and a fill level control device 455 for monitoring the fill level of the material to be filtered in the centrifugal drum 230.
    [0053] The centrifuge housing 210 has an outlet connection 460, via which the material remaining from the material to be filtered after the solid substance 264 has been filtered out can be removed from the centrifuge housing 210. The filter centrifuge 200 also has e.g. a machine base 500 and a machine frame 502 on which the various components, e.g. the filter housing 210 and the drum drive motor 234, the filter centrifuge 200 are attached and held.
