Title:
CYCLOIDAL SPEED REDUCER AND ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/064726
Kind Code:
A1
Abstract:
A high reduction ratio is achieved, and the thickness of an entire structure can be made smaller. A cycloidal speed reducer according to one aspect of the present disclosure comprises a motor and a reduction component, the motor and the reduction component being positioned in an axial direction, and the reduction component including a first gear positioned on one axial side of a first motor housing separated from the motor, and a second gear that meshes with the first gear. The motor includes two bearings positioned on the radially outer side of a rotating shaft, and the two bearings are aligned along the axial direction in the center of a stator. The first gear and the second gear of the reduction component each include two gears positioned adjacent to each other in the axial direction. Therefore, a high reduction ratio is achieved, and the thickness of the entire structure in the axial and radial directions can be made smaller.
