Abstract
The utility model relates to an input shaft connecting mechanism for a speed reducer. The input shaft connecting mechanism comprises an input shaft and a spline sleeve, wherein the input shaft is cylindrical; the spline sleeve is tubular; and one end of the spline sleeve is sleeved at one end of the input shaft. The input shaft connecting mechanism is characterized in that axial tooth crests are uniformly distributed on the outer surface of the end of the input shaft, at which the spline sleeve is sleeved; axial tooth sockets are uniformly distributed on the inner side wall of one end of the spline sleeve, which is sleeved on the input shaft; and the tooth crests on the input shaft and the tooth sockets on the spline sleeve correspond to each other in amount and size. By adoption of the input shaft connecting mechanism, the connection strength of the input shaft and the spline sleeve can be increased, the strength of the input shaft cannot be destroyed, the maintenance cost of the speed reducer is reduced, and the speed reducer is smooth in transmission and is easy to mount.
Description
Technical field
The utility model relates to a kind of planet cut speed reducer, is for the input shaft bindiny mechanism on the planet cut speed reducer specifically.
Background technique
At present, all be to be connected by spline housing between the planet cut speed reducer that in industrial field, uses, its inner input shaft and motor, so input shaft and spline housing can be referred to as the input shaft external member.Traditional input shaft external member is that spline housing one end with tubulose is placed on input shaft one end of column, the overlapping part of input shaft outer surface and spline housing inwall all is processed with rectangular teeth groove on the identical position, two teeth groove form the cavity of a cuboid, put into a size and the identical key of cavity in the cavity, can realize being fixedly connected with of input shaft and spline housing.This input shaft becomes singly-bound with the mode that spline housing is fixedly connected with and is connected, its defective is that the intensity of singly-bound often can not satisfy the requirement of use, when moment of torsion very fast when the input shaft rotating speed or that be subject to is larger, distortion can appear in corresponding teeth groove on input shaft and the spline housing, key also can be because of stressed excessive and horizontal fracture occurs, thereby so that input shaft and spline housing dislocation or slippage cause speed reducer normally not move, increased maintenance cost.And the immovable point of singly-bound Placement only has one, and speed reducer the unsettled phenomenon of transmission can occur because stress too concentrates when operation.If adopt the Placement of two keys or multikey, although can increase the join strength between input shaft and spline housing, can weaken the intensity of input shaft itself, cause distortion or the fracture of input shaft, and its installation exercise is comparatively difficult.
The model utility content
Problem to be solved in the utility model provides a kind of speed reducer input shaft bindiny mechanism, adopt this input shaft bindiny mechanism, can increase the join strength of input shaft and spline housing, and can not destroy the intensity of input shaft itself, reduce the maintenance cost of speed reducer, make speed reducer drive steady, and installation exercise is comparatively simple.
For addressing the above problem, take following scheme:
A kind of speed reducer of the present utility model comprises input shaft and spline housing with input shaft bindiny mechanism, and input shaft is cylindric, and spline housing is tubulose, and an end of spline housing is enclosed within on the end of input shaft.Be characterized in inputting axle sleeve and have being evenly equipped with axial tooth top on the end outer surface of spline housing, spline housing is enclosed within on the end madial wall of input shaft and is evenly equipped with axial teeth groove, and the tooth top on the described input shaft is corresponding with size with the teeth groove quantity on the spline housing.
The further improvement of the utility model scheme is that the tooth top on the described input shaft is the ridge shape, and the teeth groove on the spline housing is the mountain valley shape.
Take such scheme, have the following advantages:
Owing to be evenly equipped with axial tooth top on the input shaft one end outer surface of a kind of speed reducer of the present utility model with input shaft bindiny mechanism, be evenly equipped with axial teeth groove on the spline housing one end madial wall, namely the quantity of tooth top and teeth groove is a plurality of in this input shaft external member, thereby greatly increased the join strength between input shaft and spline housing, can avoid dislocation or slip phenomenon between input shaft and the spline housing, reduce the maintenance cost of speed reducer.In addition, because the tooth top on the input shaft is equivalent to key, namely key and input shaft are structure as a whole, so this structure can not destroyed the intensity of input shaft itself; And when assembling only needs that the teeth groove on the spline housing is aimed at tooth top on the input shaft and be inserted in and get final product, and need not to use other part, and installation exercise is comparatively simple.
Description of drawings
Fig. 1 is the structural representation that traditional speed reducer is used the input shaft external member;
Fig. 2 be among Fig. 1 A-A to sectional view;
Fig. 3 is the structural representation that a kind of speed reducer of the present utility model is used input shaft bindiny mechanism;
Fig. 4 be among Fig. 1 B-B to sectional view.
Embodiment
As shown in Figure 3 and Figure 4, a kind of speed reducer of the present utility model comprises input shaft 1 and spline housing 4 with input shaft bindiny mechanism, and input shaft 1 is cylindric, and spline housing 4 is tubulose, and an end of spline housing 4 is enclosed within on the end of input shaft 1.Input shaft 1 cover has on the end outer surface of spline housing 4 and is evenly equipped with axial tooth top 2, and spline housing 4 is enclosed within on the end madial wall of input shaft 1 and is evenly equipped with axial teeth groove 3, teeth groove 3 quantity on the tooth top 2 on the described input shaft and the spline housing and big or small corresponding.
Wherein, the tooth top 2 on the input shaft 1 is the ridge shape, and the teeth groove 3 on the spline housing 4 is the mountain valley shape, thereby can increase the rigidity of tooth top 2 and teeth groove 3, so that tooth top 2 and teeth groove 3 are difficult for fracture, 4 connectivities of input shaft 1 and spline housing are more firm.
