Abstract
The invention relates to an input shaft connecting mechanism for a reducer. The input shaft connecting mechanism comprises an input shaft and a spline housing, wherein the input shaft is cylindrical; and the spline housing is tubular, and one end of the spline housing 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 at one end sleeved with the spline housing of the input shaft; axial toothed grooves are uniformly distributed in an inner side wall at one end sleeved with the spline housing of the input shaft; and the number and size of the tooth crests on the input shaft correspond to those of the toothed grooves on the spline housing. By adoption of the input shaft connecting mechanism, the connection strength of the input shaft and the spline housing can be improved, the strength of the input shaft is not damaged, and the maintenance cost of the reducer is reduced, so that the reducer is stable in transmission, and the mounting operation is simple.
Description
Technical field
The present invention relates to a kind of planet cut speed reducer, is the input shaft bindiny mechanism that is used on the planet cut speed reducer specifically.
Background technique
At present, all be to be connected 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 through spline housing.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 are formed the cavity of a cuboid; Put into a size and the identical key of cavity in the cavity, can realize being fixedly connected of input shaft and spline housing.This input shaft becomes singly-bound with the mode that spline housing is fixedly connected and is connected; Its defective is that the intensity of singly-bound often can not satisfy the requirement of use, and when moment of torsion very fast when the input shaft rotating speed or that receive was big, 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 make dislocation of input shaft and spline housing or slippage, cause speed reducer normally not move, increased maintenance cost.And the immovable point of singly-bound Placement has only one, and speed reducer can occur the unsettled phenomenon of transmission because stress too concentrates when operation.If adopt the Placement of two keys or multikey, though can increase the join strength between input shaft and spline housing, can weaken the intensity of input shaft itself, cause the distortion or the fracture of input shaft, and its installation exercise is comparatively difficult.
Summary of the invention
The problem that the present invention will solve provides a kind of speed reducer and uses 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 the speed reducer stable drive, and installation exercise is comparatively simple.
For addressing the above problem, take following scheme:
A kind of speed reducer of the present invention comprises input shaft and spline housing with input shaft bindiny mechanism, and input shaft is cylindric, and spline housing is a tubulose, and an end of spline housing is enclosed within on the end of input shaft.Being characterized in that input shaft is with on the end outer surface of spline housing is evenly equipped with axial tooth top, and 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 said input shaft is corresponding with size with the teeth groove quantity on the spline housing.
Further improvement project of the present invention is that the tooth top on the said 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 invention with input shaft bindiny mechanism; Be evenly equipped with axial teeth groove on the spline housing one end madial wall; Promptly the quantity of tooth top and teeth groove is a plurality of in this input shaft external member; Thereby increased the join strength between input shaft and spline housing greatly, can avoid dislocation or slip phenomenon between input shaft and the spline housing, reduced the maintenance cost of speed reducer.In addition, because the tooth top on the input shaft is equivalent to key, promptly 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 traditional speed reducer structural representation with the input shaft external member;
Fig. 2 be among Fig. 1 A-A to sectional view;
Fig. 3 is the structural representation of a kind of speed reducer of the present invention with input shaft bindiny mechanism;
Fig. 4 be among Fig. 1 B-B to sectional view.
Embodiment
Like Fig. 3 and shown in Figure 4, a kind of speed reducer of the present invention comprises input shaft 1 and spline housing 4 with input shaft bindiny mechanism, and input shaft 1 is cylindric, and spline housing 4 is a tubulose, and an end of spline housing 4 is enclosed within on the end of input shaft 1.Input shaft 1 is with 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, and the tooth top 2 on the said input shaft is corresponding with size with teeth groove 3 quantity on the spline housing.
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, makes tooth top 2 and teeth groove 3 be difficult for rupturing, and 4 connectivities of input shaft 1 and spline housing are more firm.
