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. 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 a plurality of eccentric cylinders. The eccentric cylinders are disposed within the axle holes of the corresponding cycloid discs. 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.
