The aerial work platform are usually use slewing bearing, 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 work platform are both installed on the slewing support, that is, the turntable. The driving device is fixed on the turntable, and a driving gear is installed at the lower end. The slewing bearing is composed of a turntable and a ring gear seat fixedly connected with the frame. The slewing mechanism consists of a turntable, a cycloid hydraulic motor, a worm gear reducer, a slewing support, and a pinion gear. The outer gear ring of the slewing bearing is fixed on the chassis, and the inner ring is connected with the turntable. The rotation of the cycloidal motor drives the rotation of the worm gear reducer, the rotation of the worm gear drives the pinion gear connected to it, and the rotation of the turntable is realized by the engagement of the pinion gear and the oute
The Single Row Four Point Contact Ball Slewing Bearing
The Single Row Four Point Contact Ball Slewing Bearing is composed of 2 seat rings.It features compact in design,and light in weight.The balls contact with the circular race at four points,via which the axial force,radial force and resultant moment may be born simultaneously.
