Abstract: A cycloid speed reducer includes a weight element, an input shaft and a cycloid disc. The weight element is disposed within an accommodation space of the cycloid disc. An eccentric part is disposed on the input shaft. Since the length of the input shaft is reduced, the overall length of the cycloid speed reducer is shortened. Moreover, the mass center of the weight element and the mass center of the eccentric part and the cycloid disc are arranged along the same axial direction. That is, the line passing through the mass center of the weight element and the mass center of the eccentric part and the cycloid disc is perpendicular to the input shaft. Consequently, the efficacy of the dynamic balance of the cycloid speed reducer is enhanced.

Abstract: A two-stage cycloid speed reducer comprises two rotating disc assemblies. Each rotating disc assembly comprises two cycloid discs. In other words, the cycloid speed reducer has four cycloid discs to be in contact with the corresponding rollers. Consequently, the load withstood by each cycloid disc is reduced.

Due to the 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. Moreover, the cycloid speed reducer can be assembled easily.
