Slewing Drive

What is slewing drive

slewing drive is a full cycle rotary reduction transmission mechanism that integrates a driving power source. It uses a rotary bearing as the driving follower and mechanism attachment. By attaching an active component, driving source, and cover to one of the inner and outer rings of the rotary bearing, the other ring is used as both the driving follower and the connecting base of the driven working component. This takes advantage of the characteristic that the rotary bearing itself is a full cycle rotary connector, Efficient configuration of the driving power source and main transmission components makes it a universal reduction transmission mechanism that integrates rotation, deceleration, and driving functions, while also having a simple structure and convenient manufacturing and maintenance. The picture shows two typical slewing drives.

Features of slewing drives

Rotary drive is a highly integrated full circle rotary reduction mechanism, and its characteristics go beyond that. The difference in the maximum and minimum rotary drive can drive components and loads is tens of times, but their dimensions, especially the axial dimensions of the transmission chain, are not significantly different. This is conducive to flattening the structural form of the series transmission connecting components, thereby reducing the size of the entire mechanical equipment.

This is conducive to flattening the structural form of the series transmission connecting components, thereby reducing the size of the entire mechanical equipment.

In addition, whether it is a tooth type or a worm gear worm type Slewing Drive, due to the large size difference between the driving and driven parts themselves, it is easier to achieve high transmission ratio transmission, which is also difficult for many other types of variable speed transmission mechanisms to achieve.

Applications of slewing drives

The common applications are generally the full circle rotation structure of engineering and construction machinery, as well as solar, wind, and various long-term automatic tracking machinery. Due to its compact structure and short transmission chain, the rotation drive is easier to achieve high accuracy and digital control, so it is also widely used in the field of industrial robots.
