Slewing ring, also referred to as slewing bearings or turntable bearing, is a large bearing which can maintain the more axial load, radial load and tilting worm gear slew drive moment. It is known as: “machine joints”, the fundamental machinery transmitting parts, between your two objects that need to end up being relative rotary motion. It has the inner and outer band, rolling and other parts.
You can consider the slewing travel as a gearbox since the core motion components will be the slewing bearing and worm shaft. In addition, it consists of auxiliary elements such as seals, housing, and motor. As a power resource, slew motor is normally DC planetary gear engine or AC gear motor. AC hydraulic motor is mainly used in the structure machinery as a power get system. As the core component is slewing ring travel, slewing gearbox can easily endure the axial and radial forces. The slew drive working principle: The worm is powered by the motor, which drives the outer band of the slewing ring to rotate; The external ring output 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 features. This feature significantly enhances the stability of the host operating and safety factor. Compared to the traditional swing items, slewing get gearbox is simple to install, easy to maintain, and saves considerable installation space.
