Effective methods to prevent reverse transmission in ball screw jacks
Ball screw jacks have high transmission efficiency and cannot be locked in place. When used to transmit vertically moving components, it is essential to prevent reverse transmission due to the component's own weight after transmission interruption. The transmission efficiency of the ball screw jack nut pair is as high as 85% to 98%, which is 2 to 4 times that of ordinary sliding screws. Its static and dynamic friction coefficients are practically the same, making it one of the effective measures to improve the sensitivity of the feed system, positioning accuracy, and prevent creep. Saide Transmission reminds you of the following specific methods: 1) Use a servo motor or stepper motor that cannot reverse transmission, but the reverse torque of the motor must be greater than the inertial torque of the transmission component. 2) Use an electromagnetic or mechanical brake, or a one-way overrunning clutch. 3) Use a worm gear reducer that cannot reverse transmission.
