The rotary drive is a full-circle rotational speed reduction transmission mechanism that integrates a driving power source. It employs a slewing bearing as both the driven member and the structural attachment point. The driving components, power source, and housing are connected to either the inner or outer ring of the slewing bearing, while the opposing ring serves dual functions as both the driven element and the mounting base for the driven working components. By leveraging the inherent full-circle rotational capabilities of the slewing bearing itself, this configuration optimally arranges the power source and primary transmission elements. This innovative design creates a versatile reduction transmission mechanism that combines rotational motion, speed reduction, and driving functions in a single compact unit. The system features simplified construction with enhanced manufacturability and maintenance accessibility.

Based on the speed variation transmission forms of rotary drives, they can be categorized into gear-type rotary drives and worm-gear rotary drives, which respectively inherit the characteristics of gear transmissions and worm-gear transmissions. These two types of rotary drives are suitable for medium-high speed applications and low-speed applications respectively. In terms of load-bearing capacity, worm-gear drives demonstrate superior performance compared to gear-type transmissions. When employing enveloping worm gear drives, their load capacity, deformation resistance, and transmission rigidity are further enhanced. However, worm-gear rotary drives exhibit lower efficiency than gear-type rotary drives.
Depending on the structural openness of rotary drive mechanisms, they can be classified into open-type and enclosed-type configurations. Open-type structures are typically employed in harsh environments with short maintenance cycles. The open architecture facilitates easier inspection, maintenance, and repair of components, while also enabling simpler replacement procedures.
