Slewing ring, also referred to as slewing bearings or turntable bearing, is a large bearing which has the capacity to sustain the more axial load, radial load and tilting moment. It is known as: “machine joints”, the essential machinery transmission parts, between the two objects that require to be relative rotary motion. It has the inner and outer ring, rolling and other elements.
You can consider the slewing travel as a gearbox because the core motion components are the slewing bearing and worm shaft. In addition, it consists of auxiliary elements such as seals, housing, and motor. As a power supply, slew motor is normally DC planetary gear electric motor or AC gear motor. AC hydraulic electric motor is mainly found in the construction machinery as a power travel system. As the primary component is slewing band drive, slewing gearbox can easily withstand the axial and radial forces. The slew get working theory: 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 internal ring of the slewing ring is fixed in the housing.
Slewing drive has reverse self-locking due to worm gear drive with invert self-locking characteristics. This feature greatly enhances the worm gear slew drive balance of the host operating and safety element. Compared to the traditional swing items, slewing drive gearbox is easy to install, easy to maintain, and saves considerable installation space.
