The slewing drive is a full-circle slewing reduction transmission mechanism that integrates a driving power source. It uses a slewing bearing as a transmission follower and a mechanism attachment. By attaching a driving member and a drive source to one of the inner and outer rings of the slewing bearing And the cover, and the other ring is used as both the driving follower and the connection base of the driven working part. This makes use of the characteristics of the slewing bearing itself as a full-circle slewing connector to efficiently configure the driving power source and the main transmission. Parts, making it a universal reduction transmission mechanism that integrates slewing, deceleration and driving functions, yet has a simple structure and is easy to manufacture and maintain.
According to the type of variable speed transmission of slewing drive, it can be divided into toothed slewing drive and worm gear slewing drive, inheriting the characteristics of gear drive and worm gear worm drive. These two types of slewing drive can be adapted to medium and high-speed applications In terms of load-carrying capacity, the worm gear and worm gear perform better than the tooth type. When the envelope worm drive is used, its load-carrying capacity, anti-deformation ability, and transmission rigidity are further improved. However, the worm gear worm rotary drive is more efficient in terms of efficiency. Inferior to toothed slewing drive.
According to the openness of the slewing drive transmission, the slewing drive can be divided into open and closed. Generally, the open structure is mostly used in applications where the environment is too harsh and the maintenance and repair cycle is short. Inspection, maintenance, and service are also easier to replace. Where the environmental conditions do not change much and the environment pollution level is below moderate, the closed structure can provide a long maintenance life cycle.
