1. Working principle
The screw linear module is composed of main components such as ball screw, aluminum profile, ball screw pair, linear guide, photoelectric switch, coupling, servo motor, etc. The ball principle of the screw linear module is that the motor drives the coupling to drive the balls. The screw rotates, and the ball bearing at the bottom of the linear module allows the screw to continue the entire rotation process without moving in place. In transforming the rotating motion into the linear reciprocating motion of the linear module, this is a process for the linear module to complete the whole function.
2.the role of the product
(1) The lead of the screw linear module is small, which can maximize the thrust of the servo motor. Generally, the smaller the lead of the screw linear module, the greater the thrust. Generally used in industries with greater force and load. For example, the Z-axis is generally driven by screw rods, and a small number of low precision requirements will use rack or synchronous belt transmission.
(2) Another advantage of the screw linear module module is that its accuracy is higher than other transmission methods. The general screw linear module has a repeat positioning accuracy of ±0.01-±0.02mm, which is made according to the actual requirements of customers.
