A worm gear screw jack is a compact transmission mechanism with a high transmission ratio, featuring an automatic locking function under certain conditions. It is easy to install and well-designed, thus gaining more widespread application. By adding a helical gear reducer at the input end of a worm gear reducer, the multi-stage reducer achieves extremely low output speeds, offering higher power than a single-stage worm gear jack, with reduced vibration, noise, and energy consumption.

Based on different constructions, ball screw actuators can be divided into the following three types:

1. Belt Brakes: The braking steel belt generates braking torque by radially embracing the braking wheel.

2. Block Brakes: Two symmetrically arranged brake pads generate braking torque by radially gripping the brake wheel.

3. Disc and Cone Brakes: Metal discs with friction linings, both disc and cone types, generate braking torque when tightly pressed against each other axially.

The application range of ball screw lifting machines:

Enhancements, displacements, clamping, flipping, and other actuating devices in the production line

2. Equipment and clamping, lifting, and flipping devices for metallurgical equipment

3. Lifting equipment for the vehicle manufacturing industry, flexible work holders, and welding lift tables
