Self-locking and back-driving conditions
Trapezoidal screw jack has self-locking function which means when the rotational force on the screw is removed, it will remain motionless where it was left and will not rotate backwards, regardless of how much load it is supporting. Self-locking function is very important for some applications. Self-locking and back-driving conditions are defined in the following 4 situations: 1)Static self-l...

Worm Gear Screw Lift Running-In
We all know that there is a running-in period for the use of machinery and equipment. During the running-in period, as long as we are properly tuned, we can reduce unnecessary troubles in future use by finding problems in time. What we should pay attention to during the worm gear screw lift use? Worm screw lifts are generally self-locking static state.( Note: self-lock is a function of acme ...
