    FIELD OF THE INVENTION The invention relates to a control mechanism = for adjusting elements on a shaft in the axial direction and to a shaft assembly which includes a control mechanism. BACKGROUND OF THE INVENTION Elements on a rotating shaft are present, for example, in a screen separating material, on its screen table, i.e. on a screening plane. The screening table includes successive shafts with screening elements such as discs or stars. The screening elements of the axes in succession on the screen table are - superimposed, leaving screening openings between them. Pieces larger than the screening openings remain on top of the screen table and rotating screening elements carry the pieces, for example to a conveyor after the screen table. Pieces smaller than the screening openings fall from the screening openings of the screening table under the screening table, for example into a funnel or conveyor. The shafts are rotatably attached to the frame at both ends. The axis has elements at certain intervals with respect to each other. Corresponding shaft arrangements are also present in devices other than said screen.
    = Brief summary of the invention
    N S The aim is to implement an adjustment mechanism that allows the elements on the rotatable = axis to be adjusted relative to each other without the x 30 elements being disassembled from the axis. 3 An adjustment mechanism according to one aspect of the invention for adjusting the elements 3 on the shaft - comprises a shaft rotatably mounted on N bearings. Elements are provided on the shaft and a sleeve extending through the bearing - over the end of the shaft. The adjusting mechanism includes an adjusting member that allows the sleeve to be moved relative to the shaft so that the force exerted by the adjusting member on the sleeve is transmitted to the elements. The shaft assembly according to another aspect of the invention includes at least one adjusting mechanism arranged at one end of the shaft assembly for adjusting the elements on the shaft. BRIEF DESCRIPTION OF THE DRAWINGS - The invention will now be described with reference to the accompanying drawings, in which Figure 1 shows an axis and elements on an axis according to an embodiment of the invention. Figure 2 shows a control mechanism according to an embodiment of the invention. Figure 3 shows a control mechanism according to an embodiment of the invention. DETAILED DESCRIPTION OF THE INVENTION Figure 1 shows a shaft and elements on a shaft according to an embodiment of the invention. In Figure 1, the shaft 101 has elements 102 which are rotated by means of the shaft 101. The elements 102 of Figure 1 are disc-shaped and include an integral disc portion and a sleeve portion. The elements 102 are arranged side by side on the shaft so that the = axial sleeve part adjacent to the projecting disc part is against the corresponding N axial sleeve parts of the adjacent element. Correspondingly, the disc part of the element is against the corresponding disc part of the S adjacent element. The seam point of the adjacent elements 102 = is formed in the middle of the sleeve part and in the middle of the disc part. The shaft assembly of Fig. 1 I 30 has the same type of elements 102. Alternatively, the shaft a n 101 may have several different elements, for example the shaft of a screen> screening material> may have screening elements and between them
    LO O separate sleeves that define the distance between the screening elements. N Separate screening elements and sleeves can be used to provide a structure similar to that of Figure 1. In this case, the joint point or interface of the parts is between the separate screening elements and the sleeves.
    The shaft can be rotatably attached to the frame at both ends.
    The body may be the body of a device or component that forms a static component.
    The frame does not intentionally move.
    Other parts can be attached to the frame, for example the shaft.
    The shaft transmits rotational movement and possibly torque and / or bending torque.
    The shaft may be subjected to deformation and / or load.
    In addition, the shaft may be sensitive to vibrations.
    Vibration sensitivity is particularly evident at large shaft lengths.
    Shaft load, torque and / or bending torque may vary during operation.
    Elements connected to the shaft - cause a load force on the shaft, e.g. through strength and weight.
    The elements can cause radial force, axial force, torque and / or bending torque on the shaft.
    During operation, the load point or stress point of the shaft may vary.
    For example, the material to be handled and passed through the screen can subject the screen table and its parts to varying loads.
    On the shaft - the dimensioning of the individual elements on the shaft, the position on the shaft, the mutual clearance and / or the retention affect performance.
    During operation, the clearance of the elements may change.
    This may be due to mechanical stress, movement, forces during operation, resonance of parts such as elements, shaft or frame, materials, dimensions, shape and / or dimensional deviations.
    The shaft transmits torque to the elements on the shaft.
    The elements can be, for example - a sieve table - angular - discs or stars.
    Rotating shaft elements can be utilized in many different devices and machines.
    The elements can be round, angular, branched, symmetrical, = asymmetrical or other shaped elements.
    The elements can be fixed, N-shape retaining, deformable or flexible.
    The elements may comprise more than one material, for example their outer part or outer surface may contain = parts or consist of a material different from the material I 30 surrounding the axis of the element.
    The element may include bristles.
    An axis can have different N elements or sets of elements.
    The elements and their layout can be selected> according to the intended use.
    Mechanical rotation can cause the 3 elements to resonate or move relative to each other.
    In this case, the clearance of the elements N may change.
    This can affect the rotation of the shaft.
    For example - on the screen table, a change in the clearance of the elements can change the screening opening and / or affect the rotation of the shaft with respect to its adjacent shaft.
    The clearance of the elements on the shaft is adjustable. The aim is to keep the elements in their original positions as much as possible, for example without backing in relation to each other. The elements may be mounted on the shaft - there may be one or more spacers in or between each other, such as a sleeve against which the elements are fixed in place on the shaft. The known way of adjusting the clearance of the elements requires the removal of the shaft assembly and / or the shaft mounting. For example, the shaft can be attached to the frame with a bearing, in which case the bearing must be removed for the clearance adjustment and after the adjustment the shaft must be reattached to the frame. Usually, additional parts, such as adjustment plates or elements, are also required for this. The adjustment mechanism according to embodiments of the invention makes it possible to adjust the elements on the shaft, for example without backlash, without removing the shaft, its attachment or the elements from the shaft. Figure 2 shows a control mechanism according to an embodiment of the invention. The shaft 201 has elements 202. The elements may all be the same or similar, or the shaft may have two or more different elements. There may be a spacer between the elements against which they abut, or the elements may be adjacent to each other. The elements 202 are mounted on the shaft 201 - without backlash. In Figure 2, the shaft is attached to the body 200 by a bearing 203.
    In Figure 2, an adjusting sleeve 204 is mounted between the shaft 201 and the bearing 203. The sleeves between the shaft elements determine the distance of the elements from the shaft. The adjusting sleeve 204, which is part of the adjusting mechanism, extends through the bearing. - The adjusting sleeve 204 is a cylindrical part around the shaft 201. The inner surface of the adjusting sleeve 204 = may be against the surface of the shaft 201. The shaft 201 may have N parts in addition to or between the elements 202 and the sleeves, such as the plate S 207 shown in Figure 2. In Figure 2, the adjusting sleeve 204 is positioned against the plate on the shaft 201 = 207. When tightening the screw 206 at the shaft 201 204 slides parallel to the shaft 201, against the surface of the shaft 201. N The adjusting sleeve 204 presses against the plate 207 and the plate 207 transmits the tightening force> axially to its adjacent parts on the shaft 201. The axial force of the adjusting sleeve 204 3 causes a corresponding force on the plate 207. The plate 207 N is placed on the shaft 201 against the outermost element 202 of the shaft. In Fig. 2, the outermost element 202 comprises a unitary sleeve part. Alternatively, the outermost element of the shaft 201 may be a separate sleeve portion. Thus, the force applied to the plate 207 is transmitted through the outermost element 202 to the axially opposing elements 201 in the axial direction.
    The plate 207 or the like may be a separate part to be placed on the shaft 201, and its size and shape may vary. The other surface of the plate 207 is, either directly or via a part, against the outermost element 202 on the shaft 201, and the opposite surface of the plate 207 is, either directly or via a part, against the adjusting sleeve 204. The plate 207 transmits the tightening force axially - the adjusting sleeve 204 and the element 202 between. The plate 207 shown in Figure 2 is not necessary. The plate 207 can be used to level the edge structure of the screen table in the case of overlapping elements 202 of successive shafts 201. The plate 207 or similar part can - seal the edge of the screen table and prevent material flow from leaking from the screen table. If the alternate plate 207 is omitted, the adjusting sleeve 204 is positioned against the outermost element 202 of the shaft 201. The adjusting sleeve 204 extends from the outer end edge of the outermost element 202 of the shaft 201, such as the sleeve or sleeve portion, over the end of the shaft 201 or over the end plane of the shaft 201. Against the outer end edge of the adjusting sleeve 204 there may be a plate 205. The plate 205 may be a planar part having an outer surface and the opposite, so-called mating surface. The abutment surface of the plate 205 is positioned against the adjusting sleeve 204. In Figure 2, the abutment surface of the plate 205 is arranged against the outer end edge of the adjusting sleeve 204. The surface diameter of the plate 205 may be greater than or equal to = the diameter of the outer surface of the adjusting sleeve 204. Alternatively, the abutment surface N of the plate 205 may include, for example, an indented portion inserted within the adjusting sleeve 204 S. There may be an opening in the center of the plate 205. In Fig. 2, the opening of the plate 205 is = placed against the opening on the axis of rotation of the shaft 201. At the 30 I 30 end of the shaft, in the middle of the shaft end surface, there is an opening extending in the direction N of the axis of rotation of the shaft. The opening 20 of the plate 205 and the opening of the shaft 201 are penetrated by a screw 206, which can be called an adjusting screw. The base of the screw 206 abuts the 3 outermost surfaces of the plate 205. The hole in the shaft 201 may have threads that abut the threads of the rod portion of the screw 206.
    The shaft 201, adjusting sleeve 204, plate 205 and screw 206 of Figure 2 allow the position of the elements 202 on the shaft to be adjusted by axial movement.
    When the screw 206 at the end of the shaft 201 is tightened, the adjusting sleeve 204 on the shaft 201 slides parallel to the shaft 201, against the surface of the shaft 201, in the longitudinal direction of the shaft 201.
    The adjusting sleeve 204 compresses the elements 202 on the shaft together, against each other.
    By tightening the screw 206, a force is applied by which the adjusting sleeve 204 presses the elements 202 against each other.
    Conversely, by loosening the screw 206, the clearance of the parts on the shaft 201, such as the elements 202 and the sleeves, increases.
    This allows the clearance of the elements on the shaft - to be adjusted without removing the shaft.
    By means of the adjustment mechanism, the elements of the shaft can be compressed into a bundle, closer to each other and / or the clearance between the elements can be reduced to less, or without clearance.
    The need for adjustment is affected by, for example - manufacturing tolerances.
    For example, the manufacturing accuracy of a machine frame and the manufacturing accuracy of components to be mounted or set on it, such as modules or shaft assemblies, can cause compatibility problems.
    The adjustment mechanism can be used to adjust the parts to match.
    In addition, the clearance of the elements is adjustable - to suit the application.
    As mentioned, the clearance may change during use.
    The adjustment mechanism makes in-service adjustment quick and easy.
    This shortens maintenance times and correspondingly increases operating time.
    In Figure 2, the shaft 201 engages the body 200 via a bearing 203.
    The shaft 201 can be attached to, for example, a gusset bearing or a flange bearing.
    The bearing 203 may = engage the body 200 or the edge, edge, end, beam, plate, or the like of the screen.
    The clearance S of the elements 202 on the shaft 201 can be adjusted by means of the adjusting member 206.
    Tightening or adjusting the adjusting member 206 = causes an axial force on the adjusting sleeve 204.
    I 30 N The adjusting member can be a screw, as shown in figure 2. The shaft hole in which the adjusting member is> inserted can have threads against the screw threads.
    Alternatively, the adjusting member 3 may be a bolt which is adjusted by means of a nut.
    The adjusting member may be an integral part of the shaft or it may be fixedly mounted on the shaft.
    The adjusting member may be from the end of the shaft - a protruding pin-like part.
    Tightening or adjusting can be done by means of a part at the end of the fixed part, such as a nut.
    The adjustment clearance or adjustment allowance may depend on the dimensions of the parts. The adjustment allowance can be influenced by the depth of the hole / opening at the end of the shaft, the ratio of the depth of the opening to the length of the adjusting member and / or the length of the opposite threads therein. The adjustment allowance may run out when the tightening allowance runs out. The adjustment margin is affected by the size of the parts in relation to each other, e.g. thread length. The adjustment margin can be affected by the dimensioning and arrangement of the adjusting sleeve and the shaft, for example how far the sleeve advances from the end of the shaft. The adjustment clearance may run out when the adjusting sleeve comes into contact with the shaft end when tightened and / or when the abutment surface of the plate (205) hits the shaft end. The adjusting sleeve of the adjusting mechanism is arranged to slide against the surface of the shaft. The inner diameter of the adjusting sleeve may be larger than the outer diameter of the shaft. The difference in diameters can be, for example, 5-30 mm, or 10-20 mm. The size and shape of the abutment surfaces of the shaft and the adjusting sleeve may correspond to each other. The shaft and the adjusting sleeve are shaped in such a way that the movement of the adjusting sleeve against the surface of the shaft, and thus the adjustment by means of the adjusting mechanism of the embodiments, is possible. The design and / or dimensioning of the shaft and the adjusting sleeve in the axial direction can affect the adjustment allowance.
    The adjusting sleeve may be a cylindrical part open at both ends. In this case, there may be a plate between the adjusting sleeve and the adjusting member, by means of which the adjustment of the adjusting member is transmitted to the adjusting sleeve. The outer end of the adjusting sleeve may be a closed surface with an opening for the adjusting member. The plate can be an integral part - an adjusting sleeve. In this case, a separate tile may not be required. The plate may be a part = an adjusting member, in which case it may be a detachable or fixed part of the adjusting member, for example an N-shaped part.
    S = Figure 3 shows a control mechanism according to an embodiment of the invention. I 30 In Figure 3, the axis 301 has elements. The elements of Fig. 3 are N screening elements, discs 302. The sieve table has successive shafts 301 according to Fig. 3> so that in the longitudinal direction of the screen table the discs 302 of successive 3 axes overlap. The gap between the discs 302 is affected the size of the screening opening and thus the size of the piece of material to be screened. The size of the screening opening or the size of the pieces to be screened may be affected by the wheelbase of the successive shafts 301 of the screening table, the dimensioning of the elements 302 and any additional elements such as bushings which may be between the elements 302. The forces applied to the screen and its parts vary during use and depending on the material to be treated. The manufacturing accuracy of the frame, elements, shaft assembly and / or screen modules - can cause problems during the assembly or commissioning phases. For example, the manufacturing accuracy of the screening elements and their sizing can cause operational and / or assembly problems. Thus, in the case of a sieve, there is a need for adjustment in several stages. Figure 3 shows a shaft 301 mounted at both ends. The other end of the shaft 301 may be the so-called drive end from which the shafts are operated. The shafts can be rotated by motors from the drive end. The shafts can be operated, for example, by means of electric or hydraulic motors. The power of the motors can be transmitted to one or more shafts directly or, for example, by means of a chain, belt or gear transmission. The opposite end of the shaft 301 may be a so-called service head. The service head may have an adjustment mechanism 330 according to embodiments. The adjustment mechanism according to the embodiments may be at at least one end of the shaft. The adjustment mechanism according to the embodiments may be arranged - at both ends of the shaft. Axial direction and axial direction refer to the longitudinal direction of the axis. According to embodiments of the invention, the adjustment mechanism makes it possible to adjust the clearance of the elements per axis. For example, in a screen, several = adjacent shafts are attached to the frame. The frame can be long, for example N 5 meters or more. The long body may not be exactly the same width along its entire length S. In addition, the operation can affect various points on the screen, different = axes. Thus, the need for adjustment of the shaft elements varies. Removing the entire shaft and / or its mounting is laborious and time consuming. This causes N service breaks for the device. By means of the adjustment mechanism according to the embodiments of the invention, the adjustment of the clearance of the elements can be carried out easily, quickly and safely.
    N Embodiments of the invention have been described above. The embodiments are not intended to be limiting, but are possible embodiments and examples of the invention. Embodiments and described parts or features may be interchanged, substituted, omitted, used separately, or combined in different implementations.
