Abstract

The invention relates to a cycloid speed reducer which includes two rotating disc assemblies. Each rotating disc assembly includes two cycloid discs. In other words, the cycloid speed reducer has fourcycloid discs to be contacted with the corresponding rollers. Consequently, the load withstood by each cycloid disc is reduced. Since the cycloid speed reducer has stronger structural strength, the cycloid speed reducer can be applied to the high-load circumstance. Moreover, an eccentric assembly of the eccentric device includes plural eccentric cylinders. The eccentric cylinders are installed within the axle holes of the corresponding cycloid discs. Due to the plural eccentric cylinders, the eccentric direction of two cycloid discs is opposite to the eccentric direction of the other two cycloid discs. Consequently, it is not necessary to install an additional weight compensation device in the cycloid speed reducer to compensate the dynamic equilibrium.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a cycloidal speed reducer with high rigidity and capable of achieving dynamic balance. Background technique [0002] Generally speaking, the motor has the characteristics of high speed and low torque, so it is difficult to drive a large load. Therefore, when the motor is used to push heavy objects, it is necessary to use a reducer to reduce the speed, thereby increasing the torque. [0003] Common reducers include RV (Rotary Vector) reducer, harmonic reducer (Harmonic Drive) and cycloid reducer. RV reducer machine, such as the RV-E series reducer produced by Nabtesco, Japan, is a two-stage reduction type, which includes the first reduction part of the spur gear reduction mechanism and the differential gear reduction mechanism. The gears in the first and second reduction parts can be made of metal elements respectively. This series of reducers can reduce vibration and inertia while increasing t...
