Slewing drive can be divided into gear drive and worm gear drive according to the different transmission forms. According to the different closed forms of the transmission pair, it can be divided into open and closed types. The simplest form of slewing drive is applied to excavators, tower cranes, etc. The drive turntable on the construction machinery product is the last link of the reduction transmission chain. This kind of rotary drive is an open gear transmission, and its front end needs to be equipped with a planetary reducer with a large reduction ratio as its power input. In order to expand the application range of such products and further improve the convenience of product use and maintenance, the slewing drive with integrated worm gear drive was developed for the embryonic form of slewing drive. In order to further improve the drive capacity of the product, the enveloping worm drive It is also applied to such products. The rotary drive equipped with an envelope worm not only increases the driving torque, but also further improves the driving accuracy. It can also be digitally controlled, so it is widely used in tracking and fine-tuning devices on solar and wind power generation equipment. , In addition, it has good application effects in the fields of robots, radar, low-speed heavy-duty lifting, lifting equipment, and precision CNC turntables.
Spherical worm gear reducer rotary drive device is a new type of rotary products, usually by worm, rotary support, shell, motor and other components.As the core part adopts rotary support and enveloping worm structure, it can reach multi-tooth contact, has the characteristics of large transmission torque and smooth operation, so it can bear large axial load, longitudinal load and strong overturning moment at the same time.
Slewing drives are compact rotation units built into an iron casted housing that contains a slewing ring with a gear. A worm gear rotates a slewing ring with high precision; it enables maximum gear torque and smooth rotation. Slewing drives can handle axial, radial and tilting loads and are fully sealed.

The worm-gear type slewing drive is developed by the slewing bearing. It is composed of housing, a turbine ferrule, a worm gear, a motor and kits. Compared with the conventional slewing bearing, the structure is compacted, safe and modularity.

WH is a heavy-duty series slew drive comprising for higher capacity and one or two worms acting upon one wheel yielding maximum torque at the smallest size and weight. Typical applications are steering gears for heavy transportation, rock drill rigs, tilt rotators attached to excavators, and antenna drives. If space is not a limitation, a WH slew drive may be used which would be larger in width (diameter) and would have an increased weight compared with a WH worm drive of a comparable output torque and moment load capacity. However, the total height of the WH drive would be smaller than a WH unit.
