Background technology

At present, planet-cycloid reducer is very conventional in mechanical industry, but many planet-cycloid reducers have anti-impact Hit the problems such as ability is weak, load-carrying ability is small and transmission accuracy is poor.

Utility model content

In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of planet-cycloid reducer.

Technical scheme is used by the utility model：A kind of planet-cycloid reducer, including importation, deceleration part And output par, c, the importation include ring flange and input shaft, input shaft is rotatably supported on ring flange by bearing, institute Stating output par, c includes support, gland and output shaft, and output shaft is rotatably supported on support by bearing, the reduction part subpackage The double eccentric sleeves of 180 ° of dislocation are included, equipped with two roller bearings for being referred to as pivoted arm on eccentric bushing, H mechanisms are formed, described double Two Cycloidal Wheels are set with eccentric bushing, the Cycloidal Wheel is set on two eccentric excircle faces of double eccentric sleeves, the Cycloidal Wheel There are the odd number gear teeth, the Cycloidal Wheel is connected with output shaft by the multiple bearing pins and guide circumferentially arranged, and the one of the bearing pin End is inserted into the pin-and-hole being located on output shaft, and the other end set of bearing pin is filled with guide, and guide, which is inserted into, is located at two Cycloidal Wheels In mounting hole, the axial length of guide and the thickness of Cycloidal Wheel are equal on the bearing pin, are also equipped with being placed in two pendulum on the bearing pin The equal support plate of annulus between line wheel, the outer flank of tooth of the Cycloidal Wheel have a pin tooth assembly with matching, the pin tooth assembly by Pin wheel housing and multiple pin gear sleeves, gear pin are formed, the both ends of the surface of the pin wheel housing respectively the inner face with ring flange, in support End face is mutually compressed, and three is connected by bolt, is evenly equipped with the inner ring of the pin wheel housing consistent with the periphery of pin gear sleeve Arc groove, the pin gear sleeve and gear pin are arranged in the arc groove one by one.

During work when input shaft rotates one week with eccentric bushing, due in Cycloidal Wheel the characteristics of tooth curve and its by pin The event of gear upper pin gear limitation, the motion of Cycloidal Wheel turns into existing revolution the plane motion of rotation again, in the positive turn-week of input shaft When, eccentric bushing also rotates one week, and Cycloidal Wheel turns over a tooth so as to be slowed down in opposite direction, then by output par, c, will The low speed spinning motion of Cycloidal Wheel passes to output shaft, so as to obtain relatively low output speed by bearing pin.

The beneficial effects of the utility model are：The bearing capacity for enabling input shaft to reach balance and being driven is improved, The rigidity of gear pin is greatly improved, avoids gear pin from deforming upon, so also reduce by deformation and caused noise and Temperature rise, under same mechanism size, compared with common gear reduction unit, its bearing capacity is about the 4- of gear reduction unit 7 times；Transmission accuracy is also more much higher than common gear reduction unit.

Embodiment

It is further to the utility model below in conjunction with the accompanying drawings in order to be more clearly understood that the technical solution of the utility model Explanation.

A kind of planet-cycloid reducer as shown in Figure 1, including importation, deceleration part and output par, c, it is described defeated Entering part includes ring flange 12 and input shaft 9, and input shaft 9 is rotatably supported on ring flange 12 by bearing, the output par, c Including support 15, gland 2 and output shaft 1, output shaft 1 is rotatably supported on support 15 by bearing, and the deceleration part includes The double eccentric sleeves 10 of 180 ° of dislocation, equipped with two roller bearings 11 for being referred to as pivoted arm on eccentric bushing 10, H mechanisms are formed, in institute State and two Cycloidal Wheels 6 are set with double eccentric sleeves 10, two Cycloidal Wheels 6 are set on two eccentric excircle faces of double eccentric sleeves 10, are The bearing capacity for enabling input shaft 9 to reach static balance and being driven is improved, and Cycloidal Wheel 6 has the odd number gear teeth, the cycloid Wheel 6 is connected with output shaft 1 by the multiple bearing pins 8 and guide 7 circumferentially arranged, and one end of each bearing pin 8, which is inserted into, is located at output In pin-and-hole on axle 1, the other end set of bearing pin 8 is filled with guide 7, and guide 7, which is inserted into, to be located in the mounting hole of two Cycloidal Wheels 6, institute It is equal with the thickness of Cycloidal Wheel 6 to state the axial length of guide 7 on bearing pin 8, guide 7, which is shortened, makes guide lubricate good and uniform force, The equal support plate 13 of annulus being placed between two Cycloidal Wheels 6 is also equipped with the bearing pin 8, greatly improves the bending strength of bearing pin, it is described The outer flank of tooth of Cycloidal Wheel 6 has pin tooth assembly with matching, and the pin tooth assembly is by pin tooth 3 and multiple pin gear sleeves 4, gear pin 5 are formed, and the inner face with ring flange 12, the inner face of support 15 mutually compress the both ends of the surface of the pin wheel housing 3 respectively, and three passes through Bolt is connected, and the arc groove 14 consistent with the periphery of pin gear sleeve 4, the pin are evenly equipped with the inner ring of the pin wheel housing 3 Tooth set 4 and gear pin 5 are arranged in the arc groove 14 one by one, and when decelerator works, each gear pin 5 is compressed in pair In the space for answering arc groove 14 and the formation of the outer flank of tooth of a wherein Cycloidal Wheel 6.

During work when input shaft with eccentric bushing 10 rotate one week when, due in Cycloidal Wheel 6 the characteristics of tooth curve and its Event is limited by pin tooth assembly, the motion of Cycloidal Wheel 6 turns into existing revolution the plane motion of rotation again, is rotated forward in input shaft 9 Zhou Shi, eccentric bushing 10 also rotate one week, and Cycloidal Wheel 6 turns over a tooth so as to be slowed down, then by output section in opposite direction Point, by the low speed spinning motion of Cycloidal Wheel 6 by bearing pin 8, output shaft 1 is passed to, so as to obtain relatively low output speed.
