Description
Technical field
The utility model belongs to speed reducer technical field, is specifically related to a kind of speed reducer of input output coaxial state band speed ratio.
Background technique
In retarding device industry, speed reducer great majority are single-input single-output or single-input double-output structure, due to speed ratio, seldom accomplish that input output are on coaxial state.Generally accomplish that input shaft and output shaft are under coaxial state, in following two kinds of situations, accomplish: the one, the in the situation that of not being with speed ratio, input shaft and output shaft are the same axis, this kind of mode limited the applicable situation of equipment; The 2nd, adopt epicyclic gearbox can accomplish the same state of pto input shaft, but epicyclic gearbox cost is high and bearing capacity is low.Above two kinds of modes all have narrow limitation, can not meet user demand now.
Model utility content
Goal of the invention: the purpose of this utility model is to provide a kind of speed reducer of input output coaxial state band speed ratio, not only compact structure, easy installation and removal, and also better than the using effect of planetary speed reducer and bearing capacity, save equipment cost, be widely used.
Technological scheme: for achieving the above object, the utility model adopts following technological scheme:
A kind of speed reducer of input output coaxial state band speed ratio, it is characterized in that: comprise body, input gear axle, helical gear, output spool gear axle and output short gear axle, inside at described body is provided with bearing support, described output spool gear axle is arranged on the upper of body by bearing support, upper at body by bearing support of described input gear axle and output short gear axle, and input gear axle and output short gear axle coaxially arrange; Described helical gear is arranged on output spool gear axle, and helical gear engages with input gear axle, and output spool gear axle is in the engagement of output short gear axle, and input gear axle drives by the motor of peripheral hardware.
One end of described output spool gear axle is arranged on the outside of body, and the other end is arranged on the inside of body.
One end of described input gear axle is arranged on the outside of body, and the other end is arranged on the inside of body; One end of described output short gear axle is arranged on the outside of body, and the other end is arranged on the inside of body; The part that described input gear axle and output short gear axle are arranged on internal body is oppositely arranged.
Described input gear axle, output spool gear axle and output short gear axle are arranged in parallel in same vertical plane.
Beneficial effect: compared with prior art, the speed reducer of input output coaxial state band speed ratio of the present utility model, the output of coaxial state reduction speed ratio, the using effect and the bearing capacity that reach planetary speed reducer are better; Input gear axle and output gear shaft share a bearing support, not only simple in structure, do not take up space, and needn't carry out large transformation, be easy to maintenance and safeguard, reduced maintenance cost, suitablely apply producing in running, possess good practicability.
