Abstract

A RV bearing based speed reducer comprises a main shaft, planetary wheels, crankshafts, RV bearings, a housing and cycloidal-pin wheels, wherein a housing is of a hollow barrel shaped structure; the main shaft is coaxially arranged in the geometric center of the housing; three crankshafts are arranged with the same radian on a circle of which the center is the main shaft in a manner of being parallel to the main shaft; the planetary wheels are fixedly arranged at the lower ends of the crankshafts; a gear is fixedly arranged at the lower end of the main shaft and is engaged with all planetary gears; two RV bearings fixedly sleeve each crankshaft; two cycloidal-pin wheels sleeve the main shaft, and pores are formed in positions, where the cycloidal-pin wheels are positioned, on the crankshafts; the crankshafts penetrate the pores; two RV bearings on each crankshaft are positioned into the pores in the cycloidal-pin wheels; inner teeth which are engaged with the side edges of the cycloidal-pin wheels are arranged on the inner sidewall of the housing; and a cycloidal-pin wheel set is engaged with the inner teeth. According to the RV bearing based speed reducer, an RV speed reducer is adopted, so that the speed can be accurately adjusted; and meanwhile, high impacting load can be borne; in addition, the service life of the speed reducer can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a reducer based on RV bearings. Background technique [0002] RV transmission is a newly emerging transmission. It is developed on the basis of traditional pendulum planetary transmission. It not only overcomes the shortcomings of general pendulum transmission, but also because of its small size, light weight, large Long, stable precision, high efficiency, stable transmission and other advantages. It has increasingly received widespread attention at home and abroad. The RV reducer is composed of a cycloidal pin wheel and a planetary bracket. It is widely used in industrial robots, machine tools, and medical testing due to its small size, strong impact resistance, large torque, high positioning accuracy, small vibration, and large reduction ratio. Equipment, satellite receiving system and other fields. Compared with the harmonic drive commonly used in robots, it has much highe...
