Definition of rotary drive

Slewing drive is a kind of full circle rotary deceleration transmission mechanism integrated with driving power source. It takes slewing ring as driving follower and mechanism attachment. Through attaching driving member, driving source and cover on one of inner and outer rings of slewing ring, the other ring is regarded as driving driven member and connecting base of driven working parts, so slewing bearing is used It is the characteristic of the full circle rotary connector. The driving power source and main transmission parts are configured efficiently, which makes it a universal deceleration transmission mechanism with simple structure, convenient manufacture and maintenance, which integrates the functions of rotation, deceleration and driving. Rotary drive is a kind of high integrated full circle rotary deceleration mechanism, and its characteristics are more than that. The maximum and minimum rotary drive can drive parts and load difference dozens of times, but their size, especially the axial size of the transmission chain, is not different, which is conducive to the structural form of series transmission connecting parts flattening, so as to reduce the whole mechanical equipment 。

In addition, no matter the gear type or the worm gear type rotary drive, because the size difference between the driving and driven parts is very large, it is easier to realize the transmission with large transmission ratio, which is also difficult for many other types of variable speed transmission mechanism.
