Magnetic cycloidal gear assemblies and mounting arrangements for magnetic cycloidal gear assemblies are provided that include a fixed stator and a cycloid that rotates eccentrically within the stator. The cycloid can be mounted to an offset cam on the input shaft by a rolling element bearing. A plurality of cam followers connect the cycloid to the output hub. Various features can be provided to increase operational balance or stability. For example, an adjustable counterweight can be attached to the input shaft. Also for example, a mounting arrangement including an adjustable nut, one or more bearings, and/or one or more wave springs can be provided to allow for the application, balancing, or adjustment of axial forces within the assembly.

Magnetic cycloidal gear assembly including mounting arrangement and adjustable counterweight

The present disclosure to electromagnetically-controlled magnetic cycloidal gear assemblies and methods of operating same. In one example embodiment, such an assembly includes a stator that is concentric with respect to a primary axis of the assembly, and that includes a plurality of first magnetic devices, where each of those devices includes a respective electromagnet. Also, the assembly includes an input shaft that includes an offset cam, a cycloid mounted at least indirectly upon the offset cam, and an output hub. The cycloid is eccentric with respect to the primary axis and includes a plurality of second magnetic devices, and the output hub is at least indirectly rotationally coupled to the cycloid. The assembly also includes a controller coupled to each of the electromagnets by way of one or more linkages, and configured to govern at least one electric current that is passed through at least one of the electromagnets.
