WIPO Patent Application WO/2024/078031
Kind Code:
A1
Abstract:
The present invention relates to a reduction gearbox, a reduction motor, and a connection structure of an ice maker load part and the reduction motor. The reduction gearbox comprises a reduction gearbox shell and a reduction gearbox output shaft extending out of the reduction gearbox shell; at least three Y-shaped positioning blocks protruding upwards are arranged at the end of the reduction gearbox shell for the reduction gearbox output shaft to extend out; the at least three Y-shaped positioning blocks surround the outer side of the reduction gearbox output shaft in the circumferential direction; the Y-shaped positioning blocks each comprise a positioning part provided with an arc-shaped opening and an extension part connected to the positioning part; the arc-shaped opening of the positioning part is provided with an arc-shaped positioning surface having an opening facing the axis side of the reduction gearbox output shaft; the at least three arc-shaped positioning surfaces are formed as annular positioning surfaces coaxial with the axis of the reduction gearbox output shaft and used for positioning the load part; and the extension parts are configured to be fixed to the load part. The present invention has the advantage of ensuring that a main shaft and the reduction gearbox output shaft which are assembled rotate smoothly, so as to avoid excessive wear during use, thereby prolonging the service life and reducing noise.
