[0002] The speed of the common motor of the existing electric bicycle is about 3600-4200 revolutions per minute, and it must be decelerated to about 300 revolutions per minute to ride; After the small gear on the auxiliary shaft drives the large gear on the auxiliary shaft to decelerate, the small gear on the auxiliary shaft drives the large gear on the wheel shaft for a second deceleration and then outputs; because the side of the wheel shaft is very large, many companies are To increase the reduction ratio, the motor is made into a semi-shaft form and placed on the side of the rim, which obviously increases the volume and is not beautiful

Abstract

A motor decelerating mechanism of an electric bicycle comprises a motor, a wheel shaft, a shell and a secondary decelerating mechanism such as a drive gear or a sun gear, an intermediate gear or a planetary gear, an internal gear, and the like. The way of the deceleration is as follows: a rotating speed output by the drive gear is transmitted to the internal gear through the intermediate gear so as to enable the intermediate gear to perform deceleration movement; the internal gear drives to encircle the sun gear through the planetary gear to do the deceleration movement; and two mechanisms are combined to form the decelerating mechanism with the intermediate gear and the planetary gear. The several mechanisms have large deceleration proportions and small volumes.

Description

technical field [0001] The invention relates to a speed reduction mechanism of an electric bicycle motor Background technique [0002] The speed of the common motor of the existing electric bicycle is about 3600-4200 revolutions per minute, and it must be decelerated to about 300 revolutions per minute to ride; After the small gear on the auxiliary shaft drives the large gear on the auxiliary shaft to decelerate, the small gear on the auxiliary shaft drives the large gear on the wheel shaft for a second deceleration and then outputs; because the side of the wheel shaft is very large, many companies are To increase the reduction ratio, the motor is made into a semi-shaft form and placed on the side of the rim, which obviously increases the volume and is not beautiful. Contents of the invention [0003] The present invention is to improve the existing motor reduction mechanism. The wheel shaft on one side of the motor is connected with the motor rotor, and a gear is install...
