Introduction of Lead Screw

Trapezoidal lead screw is made of screw and T-nut. The lead screw is an essential component in linear actuators.

A leads crew (or lead screw), also known as a power screw or translation screw, is a screw used as a linkage in a machine, to translate turning motion into linear motion. Because of the large area of sliding contact between their male and female members, screw threads have larger frictional energy losses compared to other linkages. They are not typically used to carry high power, but more for intermittent use in low power actuator and positioner mechanisms.

Application of Lead Screw

Common applications are linear actuators, machine slides (such as in machine tools), vises, presses, and jacks.Lead screws are manufactured in the same way as other thread forms (they may be rolled, cut, or ground).A lead screw is sometimes used with a split nut which allows the nut to be disengaged from the threads and moved axially, independently of the screw's rotation, when needed (such as in single-point threading on a manual lathe).

Features of Lead Screw

1. Metric and imperial systems are available for lead screw.

2. Lead screw has large transmission power, accurate positioning and large bearing capacity, and has the function of self-locking.

3.Lead screw is usually suitable for transmission, so there are high requirements for quality. The turning heat treatment is carried out on the production, and then the special grinding machine is used to achieve this requirement.
