Slewing ring, also called slewing bearings or turntable bearing, is a big bearing which can maintain the more axial load, radial load and tilting moment. It really is referred to as: “machine joints”, the essential machinery transmission parts, between your two objects that need to be relative rotary movement. It has the inner and outer band, rolling and other components.
One can consider the slewing get as a gearbox since the core motion parts are the slewing bearing and worm shaft. In addition, it consists of auxiliary elements such as seals, housing, and engine. As a power source, slew motor is usually DC planetary gear motor or AC gear motor. AC hydraulic engine is mainly found in the construction machinery as a power drive system. As the core component is slewing ring travel, slewing gearbox can easily worm gear slew drive withstand the axial and radial forces. The slew travel working basic principle: The worm is driven by the motor, which drives the outer band of the slewing band to rotate; The external ring result the torque through the flange and the internal band of the slewing ring is set in the housing.
Slewing drive has reverse self-locking because of worm gear drive with reverse self-locking features. This feature significantly enhances the balance of the web host operating and safety factor. Compared to the traditional swing products, slewing drive gearbox is simple to install, simple to maintain, and saves considerable installation space.
