Slewing ring, also known as slewing bearings or turntable bearing, is a big bearing which can maintain the more axial load, radial load and tilting moment. It is known as: “machine joints”, the fundamental worm gear slew drive machinery transmission parts, between the two objects that require to be relative rotary movement. It has the inner and outer ring, rolling and other components.
One can consider the slewing travel as a gearbox since the core motion elements are the slewing bearing and worm shaft. In addition, it consists of auxiliary elements such as seals, housing, and motor. As a power source, slew motor is normally DC planetary gear engine or AC gear electric motor. AC hydraulic engine is mainly used in the structure machinery as a power get system. As the core component is slewing band drive, slewing gearbox can readily withstand the axial and radial forces. The slew get working principle: The worm is powered by the engine, which drives the outer ring of the slewing band to rotate; The outer ring output the torque through the flange and the inner band of the slewing band is fixed in the housing.
Slewing drive has invert self-locking because of worm gear drive with invert self-locking characteristics. This feature greatly enhances the stability of the host operating and safety element. Compared to the traditional swing products, slewing travel gearbox is simple to install, easy to maintain, and saves considerable installation space.
