2. Worm Gear Slew Drive Introduction
The slewing drive is a special rotary reduction product derived from the slewing ring product with high integration and large gear ratio, simple structure, easy use and maintenance.
Slewing drive can be divided into gear drive and worm gear worm shaft drive according to different transmission forms. According to the different closed form of worm gear, it can be divided into open and closed two types.
The worm gear slewing drives designed and produced by U-TRSM are available in SE/PE, WE, WEA and other series. The slewing drive can also be equipped with hydraulic motors, AC motors, DC motors, servo motors, stepping motors, etc. The bases of the slewing drives have open type and closed type. Generally, the open structure slewing drive is mostly used in applications where the environment is too wicked and the maintenance and maintenance cycle is short. The open structure slew drive is more convenient for inspection, maintenance and service of the machine parts, also more convenient to replacement. However, the closed structure can provide longer service life in occasions where the environmental conditions have not changed much and the environmental pollution level is below the medium level.
