Abstract: A rotary bearing assembly is disclosed and includes an input shaft, an inner-ring component, an outer-ring component and a load element. The input shaft is configured to combine a rotating shaft of a motor to provide a power input. The inner-ring component includes a gear set, wherein the inner-ring component is sleeved on the input shaft through the gear set and driven by the input shaft. The outer-ring component is sleeved on the inner-ring component through a load element and engaged with the gear set, wherein when the gear set is driven by the input shaft to drive the inner-ring component, the gear set drives the outer-ring component, and the inner-ring component and the outer-ring component are rotated relatively, wherein one of the inner-ring component and the outer-ring component is served to provide a power output, and a rotational speed difference is between the power input and the power output.

Abstract: A passive compliance mechanism includes a fixing member, a base and a stiffness adjustment assembly. The base is installed on the fixing member, and includes two notches and an elastic slice. A first end of the elastic slice is connected with the base. A second end of the elastic slice is located near the outer periphery of the fixing member. The stiffness adjustment assembly includes a linear guide, a sliding block and two stopping blocks. The linear guide is installed on the fixing member. The sliding block is movably installed on the linear guide. The two stopping blocks are disposed on the sliding block and synchronously moved with the sliding block. The two stopping blocks are contacted with two opposite sides of the elastic slice to clamp the elastic slice. A stiffness of the base is adjustable according to a clamped position of the elastic slice.

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.
