Problems solved by technology

In order to ensure the stability of the equipment, it is necessary to prevent the equipment from changing under the action of external force, that is, the output shaft cannot rotate under the action of external force and affect the stability of the equipment, so the output shaft needs to be self-locked
In the existing self-locking mechanism, the friction block is installed on the output shaft with interference, and another fric

Abstract

The invention discloses a self-locking device suitable for a motor and a linear actuator, and belongs to the field of motors. The motor has self-locking performance, good stability, low noise in the operation process and good user experience feeling. The self-locking device suitable for the motor comprises an end cover installed on the motor and a friction ring arranged on a motor driving shaft in a sleeving mode. A notch is formed in the friction ring, a limiting part is arranged on the periphery of the friction ring, and the end cover is matched with the limiting part so that the friction ring can tightly hold the driving shaft when the driving shaft rotates in the first direction.

Description

[Technical field] [0001] The present invention relates to a motor, and more particularly relates to a self-locking device and the linear motor is applied to the actuator. 【Background technique】 [0002] The drive element is capable of generating power, the output rotational power through an output shaft, is widely used in the various devices. In order to ensure the stability of the device, the device will be necessary to avoid changes in the external force, i.e., the output shaft is rotated by an external force can not appear to affect the stability of the equipment, so the need for self-locking the output shaft. Conventional self-locking mechanism, mounted with interference by the output shaft through the pad, the outer member further friction pad disposed to a frictional force generated by friction between the block and the output shaft rotates, the output shaft with friction or generating frictional force between the brake block and the friction member, this self-locking mecha...
