Vertical Enveloping Worm Gear Slewing Drive, Self Locking For Solar
Tracking System
Enveloping Worm Gear Slew Drive Description
1. Modularity
Due to the high integration of the rotary drive, users do not need
to purchase and process each part of the rotating device one by
one. To a certain extent, it also reduces the preparation
procedures at the beginning of product production, thereby greatly
improving labor productivity.
2. Safety
The worm gear drive has the characteristics of reverse
self-locking, which can realize reverse self-locking, that is, the
worm can only be driven by the worm, and the worm cannot be driven
by the worm. This feature makes the rotary drive can be widely used
in lifting, high-altitude operations and other equipment. While
improving the scientific and technological content of the main
engine, it also greatly improves the operation stability and safety
factor of the main engine.
3. Simplify the host design
Compared with the traditional gear transmission, the worm gear
transmission can obtain a relatively larger reduction ratio. In
some cases, the reducer parts can be omitted for the main engine,
thereby reducing the purchase cost for customers, and also greatly
reducing the occurrence of main engine failure.
