May 07, 2018

1. Slewing drive definition


Slewing drive is a new type of rotary product. It is also commonly called slewing bearing which usually consists of worm, slewing ring, housing, motor and other components. Because the core part adopts slewing bearing, it can bear axial force, radial force and overturning moment at the same time. The slewing drive has the characteristics of easy installation, easy maintenance, and greater installation space saving compared with traditional rotary products. The product can be widely used in the construction machinery and new energy fields such as heavy plate transporters, container cranes, truck cranes, aerial work vehicles, and solar power generation systems.


2. Slewing drive Structure

Slewing drive can be basically divided into single worm drive slewing drive, double worm drive slewing drive and special type slewing drive.


3.Slewing drive advantages



Due to the high integration of the rotary drive, the user does not have to procure and process each component of the rotating device one by one, and to a certain extent, the preparation process at the beginning of product production is also reduced, thereby greatly increasing labor productivity.



The worm gear drive has the characteristics of reverse self-locking, which can achieve reverse self-locking, that is, the worm gear can only be driven by the worm, and the worm gear cannot be driven by the worm gear. This feature makes the slewing drive can be widely used in lifting, high-altitude operations and other equipment, while improving the host's scientific and technological content, but also greatly enhance the host's job stability and job safety factor. Slewing drives are easier to install, easier to maintain, and save installation space to a greater extent than traditional rotary products.
