Slewing ring, also called slewing bearings or turntable bearing, is a large bearing which will be able to sustain the more axial load, worm gear slew drive radial load and tilting moment. It really is referred to as: “machine joints”, the fundamental machinery transmitting parts, between the two objects that need to be relative rotary motion. It gets the inner and outer band, rolling and other components.
You can consider the slewing get as a gearbox because the core motion components will be the slewing bearing and worm shaft. In addition, it consists of auxiliary parts such as seals, housing, and electric motor. As a power source, slew motor is usually DC planetary gear electric motor or AC gear engine. AC hydraulic electric motor is mainly found in the building machinery as a power drive system. As the primary component is slewing band get, slewing gearbox can readily withstand the axial and radial forces. The slew travel working basic principle: The worm is driven by the motor, which drives the outer ring of the slewing band to rotate; The external ring output the torque through the flange and the inner ring of the slewing band is set in the housing.
Slewing drive has reverse self-locking because of worm gear drive with invert self-locking characteristics. This feature greatly enhances the balance of the sponsor operating and safety aspect. Compared to the traditional swing products, slewing drive gearbox is easy to install, simple to maintain, and will save considerable installation space.
