Rotary drive is a full circle rotary reduction transmission mechanism that integrates a driving power source. It uses a rotary bearing as the driving follower and mechanism attachment, and attaches the driving element, driving source, and housing to one of the inner and outer rings of the rotary bearing, while the other ring serves as both the driving follower and the connecting base of the driven working component. By utilizing the characteristic of the rotary bearing itself as a full circle rotary connection, the driving power source and main transmission parts are efficiently configured, making it a universal reduction transmission mechanism that integrates rotary, reduction, and driving functions while having a simple structure, easy manufacturing, and maintenance. The picture shows two typical types of rotary drives.

According to the variable speed transmission form of rotary drive, it can be divided into toothed rotary drive and worm gear rotary drive, inheriting the characteristics of gear drive and worm gear drive respectively. These two types of rotary drive can adapt to medium high speed and low speed applications respectively. In terms of load capacity, worm gear drive performs better than toothed drive, and when using enveloping worm drive, its load capacity, deformation resistance, and transmission rigidity are further improved. However, worm gear rotary drive is inferior to toothed rotary drive in efficiency.
According to the openness of the rotary drive transmission mechanism, rotary drives can be divided into open and closed types. Open type structures are usually used in applications with harsh environments and short maintenance cycles. Open type structures are more convenient for inspecting, maintaining, and servicing components, and are also easier to replace. In situations where the environmental conditions do not change significantly and the pollution level is below moderate, a closed structure can provide a longer maintenance life cycle.
