How does the lead screw solve the challenges in industrial robots?

One challenge for manufacturers of industrial robots is to find ways to locate and control the robot's movement,although acceleration and deceleration are limited.A robot guidance system must usually combine precision,rigidity,and speed.Achieving a high level of stroke motion and rotation accuracy on the Z-axis is critical in many applications,especially when high speeds and low runouts are required.Another limiting factor is weight,especially in applications where inertia must be minimized.

A new generation of exquisitely designed lead screws is enabling industrial robot manufacturers to address these challenges.Typically,these lead screws are used to drive changes in the vertical and horizontal directions of the robot arm.This type of lead screw is used to convert the rotational output of the motor into the linear motion required to drive the arm joints.Some lead screw manufacturers offer optimized thread shapes that can significantly improve performance when used in conjunction with nuts made of special materials.

Compared with other linear motion control mechanisms,the lead screw has advantages.These include:

●They cost less

●They are self-locking and do not require a braking system

●They are better suited for vertical applications.
