1. Introduction of slewing drive

Slewing drive is a full-cycle rotation reduction transmission mechanism integrated with the driving power source. The slewing bearing is used as a transmission follower and a mechanism installation component, and the active component and the driving source are installed on one of the inner ring and the outer ring of the slewing bearing. In addition, the housing and the other ring are regarded as the connecting base of the driving follower and the driven working part. Therefore, the slewing bearing itself is a characteristic of the full circle rotating connection part, and the driving power source and the main gearbox are effectively configured. The part makes it a universal reduction transmission mechanism, which integrates the functions of rotation, reduction and driving, and has a simple structure, convenient manufacture and maintenance.

2. The type of slewing drive

1) According to the variable speed transmission form of slewing drive, it can be divided into gear slewing drive and worm gear slewing drive, inheriting the characteristics of gear transmission and worm gear transmission and their respective characteristics.

The drive can be adapted to medium speed and high speed and low speed applications respectively. In terms of bearing capacity, the performance of the worm gear type is better than that of the gear type. When the envelope worm and worm drive is used, its bearing capacity, deformation resistance and transmission stiffness have been further improved, but the worm gear type rotary drive is inferior to the toothed rotary drive.

2)According to the opening degree of the slewing drive transmission mechanism, the slewing drive can be divided into open type and closed type. Generally, the open structure is mainly used for occasions where the environment is too harsh and the maintenance period is short. The open structure is more convenient for the machine to use, and also easy for inspection and maintenance. The closed structure provides a longer maintenance life cycle. In this case, the environmental conditions will not change much and are lower than the level of environmental pollution.

Slew drive can also be called slew drive gearbox. Most of our slewing ring drive is kind of worm gear reducer. And the slew ring bearing is a slewing gear drive part. The slewing drive is a full-cycle rotary reduction transmission mechanism integrated with a driving power source.
