In addition to the chassis, the aerial work vehicle also has power transmission device, working device, safety device and hydraulic system to realize its aerial work function.
Generally, the full rotary rotary mechanism is used, and the direction of forward and reverse rotation can be selected according to the operation needs. Generally, the hydraulic motor drives the mechanical rotary device with deceleration function to rotate. The slewing part of the slewing mechanism and the operating platform are installed on the slewing bearing, namely the turntable.
The drive device is fixed on the turntable, and its lower end is equipped with a drive gear. The slewing bearing is composed of a turntable and an inner gear ring seat fixedly connected with the frame. When the driving device rotates, the gear meshes with the fixed gear ring, and the gear rolls along the gear ring, driving the turntable to rotate.
A ball or roller is installed between the turntable and the fixed gear ring seat to reduce the friction resistance of the turntable. The mechanical transmission form of the rotary mechanism can be worm and worm gear, cycloid pin gear or planetary gear.
Slewing bearing is also known as rotary bearing and slewing bearing. Slewing bearing is widely used in real industry. It is known as "the joint of the machine". It is an important transmission element required by the machine that needs to make relative rotary motion between two objects, and also needs to bear axial force, radial force and overturning moment. Its main function is to support the rotating body of the machine, reduce the friction coefficient during its movement, and ensure its rotation accuracy.
Compared with general bearings, the rotating speed of slewing ring is lower. According to the different friction properties of moving elements, slewing bearings can be divided into rolling bearings and sliding bearings.
