Slewing Drive

Gearbox for slewing drive series to enhance the rotary motion of various equipment. The slewing drive series includes various drives for hydraulic and electric prime movers, with built-in parking brake and drive pinion. The unique feature of the slewing drive device is that it has special bearings and can withstand inertia, radial and thrust loads.

What is a slewing drive?

Rotary transmission adopts rotary bearing and annular worm structure, which can realize multi tooth contact, and has the characteristics of large torque transmission and stable operation; Capable of withstanding large radial and axial loads and strong overturning moments.

Modularization
Due to the high integration of the rotary drive, users do not have to purchase and process each part of the rotary device one by one, which also reduces the preparation process at the initial stage of product production to a certain extent, thus greatly improving labor productivity.
Security
Worm gear drive has the characteristics of reverse self-locking, which can realize reverse self-locking. This feature makes the slewing drive widely used in hoisting, high-altitude operation and other equipment. While improving the technical content of the host, it also greatly improves the operating stability and operating safety factor of the host.
Simplified mainframe design
Compared with traditional rotary products, the rotary drive device is easy to install and maintain, saving installation space to a greater extent.
