The use and working principle of the slewing bearing on the aerial work vehicle

Slewing mechanism, the vehicle-mounted aerial work vehicle usually adopts a full-rotation slewing mechanism, and the forward and reverse directions can be selected according to the needs of the operation. The slewing part of the slewing mechanism and the working platform are installed on the slewing bearing, that is, the turntable. The driving device is fixed on the turntable, and the lower end is equipped with a driving gear. The slewing bearing consists of a turntable and a ring gear seat fixedly connected with the frame. The slewing mechanism is composed of a turntable, a cycloid hydraulic motor, a worm gear reducer, a slewing bearing and a pinion. The outer gear ring of the slewing bearing is fixed on the chassis, and the inner ring is connected with the turntable. The cycloid motor rotates to drive the worm gear reducer to rotate, and the worm gear rotates to drive the pinion connected to it, and the turntable is rotated through the meshing of the pinion and the outer ring gear.
