What Is Ball Screw Self-locking

Due to its high friction coefficient, the ball screw has a certain self-locking performance, which does not affect the transformation of the movement mode, but its self-locking is due to the large friction coefficient, which may cause uncontrollability and weaken the self-locking performance. Ball screws are not self-locking. If self-locking is generally required, external force intervention is required, such as using a self-locking motor, loading a brake device, and so on.

     Ball screw self-locking instructions:

     1. The easiest way: the motor has a braking function, and there are braking motors (including asynchronous motors and servo motors) for sale.

     2. The coupling between the motor and the ball screw is equipped with a brake mechanism.

     3. The motor is first connected to the worm reducer with self-locking function, and then the output shaft of the worm reducer drives the ball screw. This is troublesome and reduces the transmission accuracy.

     Fourth, install the brake mechanism on the other end of the ball screw.
