AI Technical Summary

Technical Problem

The existing actuators are prone to sliding problems after the load exceeds the self-locking force, and the friction plate loss causes the rotation shaft to increase, causing the load to deviate from the preset position.

Method used

Using a device based on the principle of one-way self-locking motor, one-way self-locking is achieved through the worm section where the rotating shaft and the worm gear mesh, and the threaded fitting structure is used to adjust the spacing between the friction member and the rotating shaft to ensure that the self-locking force is within the preset range. The friction parts can be removably replaced with wear-resistant gaskets to maintain self-locking force.

Benefits of technology

The load is stable in the preset position, avoiding the load deviation, extending the service life of the friction parts, and improving the running stability of the device and the reliability of the self-locking force.

Abstract

The utility model discloses a device based on a one-way self-locking motor principle, belongs to the field of actuators, solves the problem that the movement amount of a rotating shaft is increased after a friction plate is worn, adopts the technical scheme that the device is mainly used for driving a load to move, and comprises a shell, a rotating shaft and a worm gear, the rotating shaft is provided with a worm section meshed with the worm gear, the rotating shaft can axially move while rotating relative to the shell, and a friction piece corresponding to one axial end of the rotating shaft is arranged on the shell. The first position is separated from the friction piece when the device based on the one-way self-locking motor principle drives the load to move, the second position is attached to the friction piece when the device based on the one-way self-locking motor principle bears the load to be static, and the friction piece is arranged on the shell in an axial moving mode through a thread fit structure. And the distance between the friction piece and the rotating shaft is adjusted. The device is mainly used for enabling the distance between the friction plate and the rotating shaft to be adjustable and guaranteeing that a load is at a preset position.
