EGA5C Series Slewing Drive

One can consider the slewing drive a gearbox because the core motion components are the slewing bearing and worm shaft. It also consists of auxiliary components such as seals, housing, and motor. As a power source, the slew motor is usually a DC planetary or AC gear motor. AC hydraulic motor is mainly used in construction machinery as a power drive system. As the core component is slewing ring drive, slewing gearbox can readily withstand the axial and radial forces. The slew drives working principle: The worm is driven by the motor, which drives the slewing ring to rotate; The outer ring outputs the torque through the flange, and the inner circle of the slewing ring is fixed in the housing.Slewing drive has reverse self-locking because of worm gear drive with reverse self-locking characteristics. This feature dramatically enhances the stability of the host operating and safety factors. Compared to traditional swing products, slewing drive gearbox is easy to install and maintain and saves considerable installation space.
