Closed type hypocycloid movable teeth speed reducer

Abstract

The invention discloses a closed type movable teeth speed reducer. A high speed stage is a K-H type planetary gear train composed of an involute center wheel, three involute planetary gears uniformlydistributed in the circumferential direction, three crank shafts and a planet carrier; a low-speed stage is a movable teeth transmission mechanism composed of the three crank shafts, an movable teeth,the planet carrier, an hypocycloid machine shell and an eccentric disc shock wave generator; the crank shafts are fixedly connected with the planetary gears, the crank shafts and corresponding pin holes on the shock wave generator form a revolute pair, the spinning motion of the shock wave generator is realized by the revolution motion of the planetary gear, so that radial shock waves are generated; a sliding pair is arranged between the movable teeth and the planet carrier, the sliding pair transmits the revolution speed of the movable teeth to the planet carrier and the revolution speed isoutput through the planet carrier, so that a closed type large-speed-ratio transmission mechanism is formed. The closed type movable teeth speed reducer has the advantages of large speed ratio, zero back clearance, low error sensitivity, easy processing and the like, compared with the speed reducer for a general robot, the closed type movable teeth speed reducer is convenient to manufacture and compact in structure, and can meet the requirements of the speed reducer for the general robot.

Description

technical field [0001] The invention relates to the technical field of a reducer for robots, in particular to an innovative reducer with the advantages of small size, light weight, large speed ratio, high precision, high rigidity, and high load capacity. Background technique [0002] At present, my country is vigorously developing the high-end intelligent equipment industry represented by robots. Since 2013, my country has become the largest industrial robot market in the world for two consecutive years. At present, our country is gradually entering the development stage of industrial robot industrialization. However, in the process of industrial robot industrialization, there are many problems hindering the development. Among them, the current situation that the core components represented by precision reducers cannot be self-sufficient is particularly prominent. [0003] Precision reducers are the core components of industrial robots, accounting for more than 30% of the c...

AI Technical Summary

Problems solved by technology

Compared with foreign countries, my country's research on precision reducers for industrial robots is relatively late, and the technology is immature. There is a big gap with foreign advanced technologies, forming a situation where precision reducers cannot be self-sufficient and rely heavily on imports.
