Abstract

The invention provides a RV precise speed reducer eccentric shaft and a precise speed reducer. An annular reinforcement block is arranged in a sunken groove between two adjacent cams of the eccentricshaft; the precise speed reducer comprises a pin wheel housing, the eccentric shaft, a planet wheel, an input shaft, an output plate rack, an angular contact ball bearing and a cycloidal wheel; the planet wheel is arranged at one end of the eccentric shaft; the input shaft is located in the center of the pin wheel housing; one end of the input shaft is connected with a motor; a center gear is arranged at the other end of the input shaft; the center gear and the planet wheel are in mesh connection on the same rotation plane so as to form a first-stage planet speed reduction mechanism; and the angular contact ball bearing is arranged between the pin wheel housing and the output plate rack. According to the RV precise speed reducer provided by the invention, through increasing the diameter ofa cam connecting part, the impact resistance of the RV precise speed reducer eccentric shaft is greatly improved, the fatigue life of the RV precise speed reducer eccentric shaft is greatly prolonged, and the carrying capacity, the impact resistance, the service life and the running precision of the RV speed reducer are further improved.

Description

technical field [0001] The invention relates to the technical field of precision reducers, in particular to an eccentric shaft of the precision reducer and the precision reducer. Background technique [0002] The precision reducer is represented by the RV reducer, which has many advantages such as small size, small vibration, high rigidity, high precision, high load torque, high transmission efficiency, and large reduction ratio. It is widely used in high-precision industrial robot joints and heavy loads Under the high-precision transmission. [0003] The reduction mechanism of the RV reducer consists of a first-stage planetary reduction mechanism and a second-stage cycloidal reduction mechanism. For example, Chinese patent CN104847873A discloses a fully-sealed integrated RV reducer, including a second-stage cycloidal pinwheel deceleration structure composed of a pinion housing, a cycloidal wheel, and a needle roller, and a first-stage cycloidal pinwheel deceleration struct...
