1 Definition of slewing drive
The slewing drive device is a new type of slewing product composed of a worm gear, a slewing support, a housing and a motor. Since the core part adopts slewing bearing, it can bear axial force, radial force and overturning moment at the same time. Compared with traditional rotary products, the rotary drive has the characteristics of simple installation and convenient maintenance, which saves installation space to a greater extent. This product can be widely used in heavy-duty flatbed trucks, container cranes, truck cranes and high-altitude operations.

3. Slewing drive structure
The slewing drive can be divided into single worm drive, double worm drive and special slewing drive. Xuzhou Wanda Slewing Bearing Co., Ltd. can provide SE series and WEA series slewing drives.
SE series adopts toroidal worm structure design, multi-tooth contact, strong impact resistance, suitable for light load and low speed applications. Such as solar tracker system, small environmental protection equipment, etc. .
WEA series adopts curved tooth surface structure design, which has stronger anti-fatigue and bonding ability. It is suitable for heavy and medium speed applications. Such as construction machinery, construction machinery, etc. .
