Ball screw true or false judgment
Ball screw pairs are made of screw、nut、A mechanical component composed of parts such as balls。It will rotate,It turns into a straight line,Or turn a linear motion into a rotational motion,High transmission efficiency、High positioning accuracy、Transmission reversibility、Long service life and good synchronization performance,Therefore, it is widely used in various industrial equipment、Precision instruments and precision CNC machine tools。In recent years
Assembly of ball screw pairs in large CNC machine tools
The difference between ball screw and ordinary screw
Worm wheel screw lift is a compact structure、Large transmission ratio,Transmission machinery with self-locking function under certain conditions。And easy to install、Reasonable structure,It has been used more and more widely。It is the worm in the worm wheel The input end of the reducer is fitted with a incline Gear reducer,The multistage reducer can obtain very low output speed,Higher than single-stage worm gear lift
