Abstract

A gear motor, comprising a motor (1) and a speed reducer (2) which are in a connection fit with each other. An output end of the speed reducer (2) is fixedly connected to a front block plate (3). The front block plate (3) is fixedly connected to a rear block plate (5) by means of transverse plates (4) on both sides. An output shaft (6) of the speed reducer (2) passes through the front block plate (3) and the rear block plate (5). The output shaft (6) is of a segmented structure. A first friction disc (7) and a second friction disc (8) are fixed on cross sections, respectively. End surfaces of the first friction disc (7) and the second friction disc (8) are in a contact fit with each other. Bearings for supporting the output shaft (6) are mounted in both the front block plate (3) and the rear block plate (5). When the gear motor is stuck, the two friction discs slide relative to each other, thereby protecting the internal gear of the speed reducer and preventing the motor from being damaged, and improving the overall durability.

One and two friction discs, the end faces of the first friction disc and the second friction disc are in contact with each other, and the front baffle and the rear baffle are equipped with bearings for supporting the output shaft.

In the utility model, compared with the traditional deceleration motor, the output shaft of the reducer is designed to be segmented, and the friction disc is fixed at the cross section of the shaft to realize the cooperative transmission through the contact of the friction surfaces of the two friction discs, further for It is convenient for the installation and fixing of the segmented output shaft, and the front baffle, the horizontal plate and the rear baffle are fixed outside the output end of the reducer to form a frame structure.

In the above geared motor, a C-shaped bracket is vertically fixed on the rear baffle, and the bracket is located between the rear baffle and the front baffle. Shaft bearings.

In the above geared motor, a shrapnel is provided on the output shaft between the bracket and the second friction disc, one end of the shrapnel abuts against the bracket and the other end abuts against the back of the second friction disc.

In the above-mentioned geared motor, the elastic piece is sleeved on the output shaft through a shaft sleeve.

In the above geared motor, the first friction disc is provided with a circle of annular separation grooves.

In the above geared motor, a weight reducing hole is opened in the center of the horizontal plate.

In the above-mentioned geared motor, the output shaft and the shaft of the motor are parallel to each other.

Beneficial effect

Compared with the prior art, this deceleration motor designs the output shaft on the reducer into segments, and at the same time transmits torque through the cooperation and contact of two corresponding friction discs, so when the deceleration motor is stuck, it will cause mutual friction between the two friction discs. Skidding, thereby protecting the internal gears of the reducer and the motor from damage, increasing the overall durability.
