Pinch Type Cycloid Reducer and Industrial Robot

摘要

A pin-type cycloidal speed reducer and an industrial robot are provided. The pin-type cycloidal speed reducer includes an axially arranged first and second cycloidal structure systems, wherein the first cycloidal structure system is sleeved on an eccentric shaft, and each cycloidal structure system includes at least one Of a cycloid structure; The cycloid structure includes a cycloid disk, a plurality of circumferentially distributed pin-teeth, and a pin-like housing continuously disposed radially inwardly outwardly; A plurality of pin-shaped portions being rotatably fixed to the pin-shaped housing, the cycloidal disk engaging a plurality of pin-shaped teeth; All pin-to-pin housings of the pin-type cycloidal speed reducer are arranged coaxially; The at least one cycloid disk of the second cycloid structure system and the at least one cycloid disk of the first cycloid structure system are fixed in the circumferential direction and the circumferentially fixed cycloid disks are coaxially arranged. During power transmission from the eccentric shaft to the cycloid disk in the first cycloid structure system, the pinned cycloidal speed reducer is subjected to the first deceleration. During power transmission from the cycloid disk to the pinned housing in the second cycloid structure system, the pinned cycloidal speed reducer undergoes a second deceleration. Thus, deceleration can be achieved.
