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.
