worm gear slew drive

Slewing ring, also referred to as slewing bearings or turntable bearing, is a large bearing which is able to maintain the more axial load, radial load and tilting moment. It is referred to as: “machine joints”, the fundamental machinery transmission parts, between your two objects that require to be relative rotary movement. It gets the inner and outer ring, rolling and other parts.
You can consider the slewing drive as a gearbox since the core motion parts are 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 normally DC planetary gear electric motor or AC gear engine. AC hydraulic electric motor is mainly used in the structure machinery as a power drive system. As the core component is slewing band drive, slewing gearbox can easily withstand the axial and radial forces. The slew travel working theory: The worm is powered by the motor, which worm gear slew drive drives the external ring of the slewing band to rotate; The external ring result the torque through the flange and the inner ring of the slewing ring is set in the housing.
Slewing drive has invert self-locking due to worm gear drive with invert self-locking characteristics. This feature greatly enhances the stability of the host operating and safety element. When compared to traditional swing products, slewing drive gearbox is simple to install, simple to maintain, and will save considerable installation space.
