Slewing ring, also known as slewing bearings or turntable bearing, is a big bearing which is able to maintain the more axial load, radial load and tilting moment. It really is referred to as: “machine joints”, the essential machinery transmission parts, between the two objects that require to be relative rotary motion. It has the inner and outer band, rolling and other components.
One can consider the slewing drive as a gearbox since the core motion parts will be the slewing bearing and worm shaft. In addition, it consists of auxiliary components such as for example seals, housing, and motor. As a power source, slew motor is usually DC planetary gear engine or AC gear motor. AC worm gear slew drive hydraulic motor is mainly used in the building machinery as a power travel system. As the primary component is slewing ring get, slewing gearbox can easily endure the axial and radial forces. The slew get working principle: The worm is driven by the electric motor, which drives the external band of the slewing ring to rotate; The outer ring result the torque through the flange and the internal ring of the slewing band is set in the housing.
Slewing drive has reverse self-locking due to worm gear drive with reverse self-locking features. This feature significantly enhances the balance of the sponsor operating and safety factor. Compared to the traditional swing products, slewing get gearbox is easy to install, easy to maintain, and will save considerable installation space.
