Title:
DECELERATION DEVICE AND ELECTRICAL EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2022/064725
Kind Code:
A1
Abstract:
The present invention can make an overall structure have a smaller thickness while achieving a high reduction ratio. This deceleration device comprises a motor and a deceleration component. The motor and the deceleration component are arranged in an axial direction. The deceleration component includes a first gear located on a side, of a first motor housing, spaced apart from the motor, a second gear engaged with the first gear, and a third gear engaged with the second gear. The first gear, the second gear, and the third gear are located on one side of the first motor housing in the axial direction. The deceleration component includes at least one bearing located radially inside the first gear. The number of the first gear is at least one. The second gear and the third gear each include two gears arranged adjacent to each other in the axial direction. Therefore, the present invention can make an overall structure have a smaller thickness in the axial direction and the radial direction while achieving a high reduction ratio.
