WE Series Slewing Drive – High Torque, Compact Rotary Reducer for Heavy Machinery
WE Series Slewing Drive – High Torque, Compact Rotary Reducer for Heavy Machinery
Slewing Drive: Full-Cycle Rotary Reduction Transmission Mechanism with Integrated Power Source
The slewing drive is a rotary reduction transmission mechanism that integrates a driving power source. It utilizes a rotary bearing as the driving follower and mechanism attachment. By connecting the active component, driving source, and cover to one of the inner or outer rings of the rotary bearing, the other ring acts as both the driving follower and the connecting base for the driven working component.

WE Series Slewing Drive – High-Performance Rotary Reduction Transmission for Heavy-Duty Applications
What is WE Series Slewing Drive?
The WE series slewing drive is a complete rotary reduction transmission system that integrates the driving power source with the rotating bearing mechanism. By connecting the driving component, power source, and cover to one of the inner or outer rings of the slewing bearing, the opposite ring acts as the driving follower and base for the working component. This design leverages the unique properties of the rotary bearing as a full-cycle rotary connector, efficiently combining rotation, deceleration, and drive functions in a simple structure. The WE series is known for its ease of manufacturing and maintenance.

Key Features of WE Series Slewing Drive
The WE series slewing drive is a highly integrated rotary reduction mechanism with unique characteristics. The difference in the maximum and minimum load-bearing capacity of the components in the WE series slewing drive is vast, but their dimensions, especially the axial dimensions, remain relatively similar. This compact design helps streamline the overall structure, reducing the size of the mechanical equipment.
Additionally, whether using a tooth-type or worm gear worm-type WE series slewing drive, the significant size difference between the driving and driven parts makes it easier to achieve high transmission ratios. This ability to handle higher ratios is a feature that distinguishes the WE series from many other variable-speed transmission mechanisms.
Applications of WE Series Slewing Drive
High-altitude work platforms
Fire truck ladders
Marine cranes
Log transfer machines
