Slewing ring, also known as slewing bearings or turntable bearing, is a big bearing which has the capacity to maintain 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 need to be relative rotary movement. It has the inner and outer band, rolling and other elements.
You can consider the slewing drive as a gearbox because the core motion components are the slewing bearing and worm shaft. In addition, it consists of auxiliary elements such as for example seals, housing, and engine. As a power source, slew motor is usually DC planetary gear engine or AC gear motor. AC hydraulic motor is mainly used in the structure machinery as a power drive system. As the core component is slewing ring get, slewing gearbox can readily endure the axial and radial forces. The slew get working principle: The worm is powered by the motor, 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 ring is set in the housing.
Slewing drive has reverse self-locking due to worm gear drive with invert self-locking features. This feature significantly enhances the stability of the sponsor operating and safety aspect. When compared to worm gear slew drive traditional swing items, slewing drive gearbox is easy to install, simple to maintain, and will save considerable installation space.
