Drive Slew Ring Application Compendium


Drive slew rings consist of a slew bearing, worm shaft, housing, shaft bearings and a motor in an integrated package with a hollow bore. The motor drives the worm shaft which in turn drives the outer ring of slew bearing causing it to rotate. The outer ring is attached to a rotating flange while the inner ring of the drive slew ring slewing bearing is fixed to the stationary housing.
