Slewing ring, also called slewing bearings or turntable bearing, is a large bearing which has the capacity to maintain the more axial load, radial load and tilting moment. It is known as: “machine joints”, the fundamental machinery transmitting parts, between your two objects that require to be relative rotary motion. It gets the inner and outer band, rolling and other elements.
You can consider the slewing get as a gearbox since the core motion components are the slewing bearing and worm shaft. In addition, it consists of auxiliary components such as seals, housing, and engine. As a power supply, slew motor is worm gear slew drive normally DC planetary gear electric motor or AC gear engine. AC hydraulic motor is mainly used in the construction machinery as a power get system. As the primary component is slewing band drive, slewing gearbox can easily endure the axial and radial forces. The slew get working basic principle: The worm is powered by the electric motor, 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 band is fixed in the housing.
Slewing drive has invert self-locking because of worm gear drive with invert self-locking features. This feature significantly enhances the stability of the web host operating and safety factor. When compared to traditional swing products, slewing drive gearbox is easy to install, easy to maintain, and will save considerable installation space.
