The Introduction Of Slewing Drive
May 02, 2018

Slewing drive is a full-circle rotary speed reduction transmission mechanism integrated with a drive power source. It uses a slewing bearing as a transmission follower and a mechanism attachment member, and a driving member and a driving source are attached to a ring in the inner and outer rings of the slewing bearing. And the cover, and the other ring is used as a drive follower and as a connection base for the driven working parts, so the use of the slewing bearing itself is a feature of the full-circumference rotary joints, efficiently configuring the drive power source and the main drive Parts, making it a kind of general-purpose deceleration transmission mechanism that integrates rotation, deceleration and drive functions while being simple in structure and convenient in manufacture and maintenance. The picture shows two typical slewing drives.


The slewing drive is a highly integrated full-circle slewing speed-reducing mechanism. Its characteristics are not limited to that. The maximum and minimum slewing drives can drive the components and loads by several times, but their size, especially the drive chain axis The difference in size is not large, so that it is favorable for the flattening of the structure of the tandem drive connecting parts, so that the entire mechanical equipment can also be reduced.


In addition, whether it is a gear type or a worm gear type slewing drive, since the size difference between the main and driven parts themselves is large, it is easier to realize a large gear ratio transmission.
