Magnetic transmission systems with eccentric bearing assemblies

A magnetic transmission system, comprising:

• an outer gear ring comprising an outer plurality of permanent magnets and configured to rotate about a rotational drive axis;
• an inner gear ring positioned within the outer gear ring and comprising an inner plurality of permanent magnets magnetically coupled to the outer plurality of permanent magnets, and a plurality of eccentric bearing assemblies circumferentially spaced about the rotational drive axis, each of the plurality of eccentric bearing assemblies comprising a bearing spacer, an outer bearing assembly rotatable about an outer bearing rotational axis, and an inner bearing assembly rotatable about an inner bearing rotational axis of the bearing spacer that is radially offset from the outer bearing rotational axis;
• and
• a first drive shaft coupled to the outer gear ring and a second drive shaft coupled to the inner gear ring, wherein the outer gear ring and the inner gear ring are configured to provide a gear ratio between the first drive shaft and the second drive shaft;
• wherein the bearing spacer of each of the plurality of eccentric bearing assemblies comprises a central passage, an outer bearing surface surrounding the central passage having a central axis that extends through the central passage, and an inner bearing surface defining the central passage and having a central axis that extends through the central age and is radially offset from the central axis of the outer bearing surface.
