SE Series Slew Drive with Worm Gear Reducer
The SE series slew drive is a fence-type slewing reducer utilizing a worm gear drive that offers reverse self-locking capabilities. It is designed to provide reliable and efficient rotation for a variety of heavy-duty applications, including aerial work platforms, firetruck ladders, marine cranes, and log transfer machines.
Features of SE Series Slew Drive
SE series slew drive, also known as a rotary gear device, integrates a rotary bearing, worm, casting base, and standard components like bearings and bolts. The use of wheel axle motion reduces force consumption while offering safety protection.
This slewing drive is a full-circle rotary reduction mechanism that combines rotation, deceleration, and driving functions. By attaching the active component, driving source, and cover to one of the rings of the rotary bearing, the opposite ring serves as both the driving follower and the base for the driven component. This configuration optimizes the characteristics of the rotary bearing to achieve high efficiency.
