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