Slewing ring, also referred to as slewing bearings or turntable bearing, is a big bearing which has the capacity to sustain the more axial load, radial load and tilting moment. It is known as: “machine joints”, the fundamental machinery transmission parts, between your two objects that require to be relative rotary motion. It gets the inner and outer ring, worm gear slew drive rolling and other parts.
One can consider the slewing travel as a gearbox since the core motion parts will be the slewing bearing and worm shaft. It also consists of auxiliary elements such as seals, housing, and motor. As a power resource, slew motor is usually DC planetary gear engine or AC gear engine. AC hydraulic engine is mainly found in the structure machinery as a power drive system. As the core component is slewing ring travel, slewing gearbox can readily endure the axial and radial forces. The slew travel working theory: The worm is driven by the motor, which drives the external band of the slewing band to rotate; The outer ring output the torque through the flange and the inner ring of the slewing ring is set in the housing.
Slewing drive has reverse self-locking because of worm gear drive with reverse self-locking characteristics. This feature significantly enhances the stability of the host operating and safety factor. When compared to traditional swing products, slewing drive gearbox is simple to install, simple to maintain, and saves considerable installation space.
