Product Description

Introduction:

Trapezoidal lead screw is mainly used to convert rotating motion to linear motion to achieve precise positioning and load transfer.

Trapezoidal lead screw is a screw drive element, through the nut and screw screwing, can convert the rotating motion into linear motion. This ability to convert motion makes the trapezoidal lead screw widely used in mechanical systems, especially in the need of high precision positioning, such as numerical control machine tools and precision measuring equipment, trapezoidal lead screw provides precise linear motion, to meet the high demand for position accuracy applications. In addition, trapezoidal lead screw can also effectively transfer the load, is suitable for the need to bear more force or torque occasions, become a reliable force transmission element.


Application:

Lead screw has a wide range of applications, not only used in the machine tool industry lathe longitudinal feed system, is also widely used in lifting platform, lifting mechanical arm and other lifting devices. In addition, trapezoidal lead screw is also commonly used in equipment that need manual control, such as manual lifting platform and manual adjustment device, by manually rotating the screw, can be realized on the nut up and down, to achieve accurate position adjustment.

In general, keystone screw with its high efficiency, low cost characteristics, plays an important role in the field of industrial automation and precision machinery, for a variety of process to provide accurate control.
