    PERFECTED PARALLEL REDUCER OBJECT OF THE INVENTION
    The purpose of the present invention request is to register an improved parallel reducer, which incorporates notable innovations and advantages over the techniques used so far.
    More specifically, the invention proposes the development of an improved parallel reducer, which by its particular disposition, allows to provide the dimensional advantages and performance of the planetary reducers, that is, to have a parallel reducer with output shaft coaxial to that of the torque supply motor , and can therefore be installed in tubular spaces, and all this without diminishing the usual advantages in parallel reducers.
    BACKGROUND OF THE INVENTION
    Both parallel reducers and planetary reducers are known in the current state of the art.
    In the case of known parallel reducers, the input and output shafts are parallel but not aligned. However, they are known for their very high efficiency, low price and low noise emission, although they usually need more mounting space.
    In the case of known planetary reducers, the input and output axes are aligned, thus allowing their installation in tubular spaces, although they increase their length as they increase their relationship.
    The present invention contributes to solving and solving the present problem, since it maintains the usual advantages and benefits of parallel reducers, and at the same time having an output shaft coaxial to that of the torque supply motor, and therefore being able to be installed in spaces tubular

    The improved parallel reducer of the invention further comprises a volumetric housing 3 and a transmission mechanism disposed between the input shaft 1 and the output shaft 2 and arranged parallel to the input shaft 1 and the output shaft 2 and contained therein. inside of the housing 3.
    In this preferred embodiment represented in the drawings, as can be seen above all in Figures 2, 3 and 4, the transmission mechanism comprises wheel stems 4, 5 and an intermediate shaft 6 arranged in an intermediate position. between input shaft 1 and output shaft 2.
    Said rod-wheel 4, 5 and intermediate shaft 6 are parallel to the input shaft 1 and the output shaft 2, and are contained in the housing 3.
    Figures 2, 3 and 4 appear devoid of the housing 3, to facilitate the understanding of its interior content.
    The housing 3 is provided with an upper base 31, an intermediate base 32 and a lower base 33. In this preferred embodiment, the housing 3 has a cylindrical geometry, and the upper bases 31, intermediate 32 and lower 33 have a geometry. circular, the input shaft 1 and the output shaft 2 coinciding with the axial axis of the cylindrical housing 3.
    Figure 3 appears devoid of the upper base 31, and Figure 4 appears devoid of the upper base 31 and the intermediate base 32, to thereby facilitate the understanding of the interior details of the improved parallel reducer of the present invention.
    In accordance with the described arrangement and as shown schematically in Figure 2, the housing 3 is therefore divided into an upper compartment 34 limited by the upper base 31 and the intermediate base 32, and a lower compartment 35 limited by the intermediate base 32 and lower base 33.
    At the same time, the upper base 31 is enabled for the entry and passage of the input shaft 1 itself with its rotating movement.

    As can be seen schematically above all in Figures 4, 5 and 6, in the upper compartment 34 and therefore on the intermediate base 32, a rod-wheel 4 is positioned.
    The rod-wheel 4 in turn comprises a rod 41 and a concentric and rotating geared wheel 42 freely relative to the rod 41 itself.
    At the same time the upper base 31 and the intermediate base 32 are enabled by their respective holes 314, 324 to keep the rod 41 of the rod-wheel 4 in position and at the same time receive the rotational movement of the input shaft 1 in the wheel 42 geared.
    The rotational movement communication between the input shaft 1 and the wheel rod 4 is effected by gearing between the geared wheel 42 a surface meshed on the input shaft 1 itself, all suitable in its contact for the communication of its movements rotating
    As can also be seen schematically above all in Figures 4, 5 and 6, the rod-wheel 5 is also positioned in the upper compartment 34 and therefore on the intermediate base 32.
    The rod-wheel 5 in turn comprises a rod 51 and a concentric and rotating geared wheel 52 freely relative to the rod 51 itself.
    At the same time the upper base 31 and the intermediate base 32 are enabled by their respective holes 315, 325 to keep the rod 51 of the rod-wheel 5 in position and at the same time receive the rotary movement from the geared wheel 42 to the wheel 52 geared.
    The rotational movement communication between the rod-wheel 4 and the rod-rod 5 is effected by a lower geared pinion 42 integral to the wheel 42, which properly meshes with the wheel 52 meshed with the rod-wheel 5.
    The intermediate shaft 6 is through and crosses the intermediate base 32 through its hole 326 and is therefore positioned simultaneously in the upper compartment 34 and in the
    5
    10

    lower compartment 35. The upper base 31 and the lower base 33 are enabled by their respective holes 316, 336 to keep said intermediate shaft 6 in position and at the same time receive the rotary movement of the previous rod-wheel 5.
    For the communication of rotary movement between the rod-wheel 5 and the intermediate shaft 6 through, the same intermediate shaft 6 through, in turn, comprises a concentric meshed wheel 61 with the intermediate shaft 6 itself and integral with it. Said wheel 61 is suitably engaged with a lower gear pinion integral with the wheel 52.
    Finally, the communication of rotational movement between the intermediate shaft 6 through and the output shaft 2 is effected by a surface engaged in the intermediate shaft 6 and a gear wheel 21 in the output shaft 2 and concentric and integral with it, suitable in your contact and gear for the communication of your rotating movements.
    In this preferred embodiment, the lower base 33 is provided with a housing 332 where a bearing (not shown in the drawings) is housed for the passage of the output shaft 2, while allowing its rotation. In the intermediate base 32 there is another housing 322 for another bearing (not shown in the drawings) to give stability to the rotation of the output shaft 2.
    The improved parallel reducer of the present invention provides the dimensional advantages of the planetary reducer, that is, having a parallel reducer with an output shaft coaxial to that of the motor, and suitable above all for operation with motor pairs between 5 Nm and 25Nm
    In the improved parallel reducer of the invention, instead of using two structural parts (box and cover) as is usually done, an intermediate base 32 or plate is used that divides the improved parallel reducer of the invention internally into two upper compartments 34 e lower 35, one for the initial reduction stages and one for an output reduction stage located in a second level.
    The housing 322 of the bearing of the output shaft 2 in the intermediate base 32 guarantees a greater resistance therein, which represents an additional advantage over the planetary gearboxes, which normally use two bearings in the same output region, and which supposes a decrease in its radial resistance. The transmission between the

    35
    Upper compartment 34 and lower 35 of the improved parallel reducer of the present invention is realized by the intermediate shaft 6 through.
    In other preferred embodiments more simplified and not shown in the drawings, the transmission mechanism may comprise only one intermediate axis, disposed between the input axis 1 and the output axis 2 and being parallel thereto, said intermediate intermediate axis being by the intermediate base 32 and therefore positioned simultaneously in the upper compartment 34 and in the lower compartment 35 and the upper base 31, the intermediate base 32 and the lower base 33 being also enabled to keep said intermediate axis in its position and at at the same time receive the rotary movement of the input shaft 1 and transmit it to the output shaft 2.
    The internal arrangement explained and described of the improved parallel reducer of the present invention, allows to perform 2, 3 and 4 stages of reduction and ratios from 4: 1 to 160: 1 depending on the internal engagement in between the wheel-rods 4, 5 and the through intermediate axle 6, thus being the ability to reduce the invention dependent on the amount of possible intermediate axles and / or intermediate rod-rods existing in the transmission mechanism, which is an important advantage over planetary reducers, therefore, to get such high relationships, they need to have a great length.
    The lower base 33 as well as the output shaft 2 connected with it, have the property of being detachable and reversibly removable from the rest of the parallel reducer perfected of the invention. When this happens, the intermediate shaft 6 freely protrudes from the intermediate base 32, as shown schematically in Figure 8. In such a case, with said new resulting arrangement, it is the intermediate shaft 6 which exhibits the outgoing rotating movement of the perfected parallel reducer of the invention.
    This explained arrangement is reversible, in the sense that after reassembly of the lower base 33 as well as the output shaft 2 connected with it, the projecting rotating movement of the improved parallel reducer of the invention is presented again by the output shaft 2.
    The improved parallel reducer of the invention also has a lower manufacturing time and cost than the conventional parallel axis reducer.
    The details, shapes, dimensions and other accessory elements, as well as the materials used in the manufacture of the perfected parallel reducer of the invention, may be conveniently substituted by others that are technically equivalent and do not depart from the essentiality of the invention. nor of the scope defined by the claims included below.
