Abstract
A cycloid speed reducer includes an input shaft, a rolling assembly, first and second cycloid discs, a crankshaft and an output disc. The first and second cycloid discs are disposed around the input shaft and driven by the input shaft. The first and second cycloid discs are located at two opposite sides of the rolling assembly, respectively. The crankshaft includes first and second eccentric ends and first and second concentric ends integrally formed as a one-piece structure and arranged sequentially. The first and second eccentric ends are linked with the first and second cycloid discs respectively. An eccentricity value is between any neighboring two of the concentric and eccentric ends. The diameters of all the concentric and eccentric ends are equal. The output disc is linked with the first or second concentric end. The output disc is a power output end of the cycloid speed reducer.
