Worm gear screw lift foundation: worm drive
Worm gear transmission is a commonly used mechanical transmission with large transmission ratio. It is widely used in machine tools, instruments, lifting and transportation machinery and construction machinery.
The worm drive consists of a worm and a worm gear, which transmits the motion and power between the two staggered shafts. Generally, the worm is the active part, and the worm wheel is the driven part. Usually, the worm used in the project is an Archimedes worm, which looks like a screw with a trapezoidal thread and has an axial interface similar to that of a linear toothed rack. The worm has left-handed and right-handed points, generally right-handed.
The main feature of the worm drive of the worm gear screw lift is stable operation and low noise. The worm has a self-locking effect when the helix angle is small. However, the transmission rate is low and the price is relatively expensive. It is generally used in conjunction with a special reducer for construction lifts.
