Slewing drive features
- Sep 06, 2018 -

The slewing drive is a highly integrated full-cycle rotary reduction mechanism. It is not only characterized by the fact that the largest and smallest slewing drives can drive dozens of times the load and load, but their size, especially the drive chain axial The difference in size is not large, which is advantageous in flattening the structural form of the series transmission connecting mechanism, so that the entire mechanical equipment is also reduced.

In addition, whether it is a tooth type or a worm gear type slewing drive, since the size difference between the main and driven parts itself is large, it is easier to realize the transmission of the large transmission ratio, which is also difficult for many other types of variable speed transmission mechanisms. of.

The slewing drive is a full-cycle rotary reduction transmission mechanism integrated with a driving power source. The slewing bearing is used as a transmission follower and a mechanism attachment member, and an active member and a driving source are attached to one of the inner and outer rings of the slewing ring. And the casing, and the other ring is regarded as both the transmission follower and the connecting base of the driven working part, so that the slewing bearing itself is a feature of the full-circle rotary connecting member, and the driving power source and the main transmission are efficiently configured. The part makes it a general-purpose reduction transmission mechanism that integrates the functions of rotation, deceleration and drive, while having a simple structure and convenient manufacture and maintenance. The picture shows two typical rotary drives.
