Enclosed Housing Self Locking Slewing Drive Gearbox For PV Solar
Tracking System
Slewing Drive Gearbox Description
The worm gear slew drive has the characteristics of reverse
self-locking, which can realize reverse self-locking, that is, the
gear can only be driven by the worm. This feature makes the slew
drive be widely used in solar energy, antenna, 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.
According to the variable speed transmission form of slewing drive,
it can be divided into gear slewing drive and worm gear slewing
drive, inheriting the respective characteristics of gear drive and
worm gear drive. In terms of bearing capacity, the performance of
the worm gear type is better than that of the tooth type, and when
the enveloping worm drive is used, its bearing capacity,
anti-deformation ability and transmission rigidity are further
improved, but the worm gear type slewing drive is less efficient in
terms of efficiency. Inferior to the gear slewing drive, the gear
slewing drive is further divided into spur gear type slewing drive,
helical gear type slewing drive, and vortex type slewing drive.
