Self Lock Features
The worm gear and worm drive have the characteristics of reverse
self-locking, that is, only the worm can drive the worm gear, but
the worm gear cannot drive the worm to move. When the lead angle of
the worm is less than the equivalent friction angle between the
meshing gear teeth, the mechanism has self-locking properties and
can achieve reverse self-locking, that is, only the worm can drive
the worm wheel, but the worm cannot be driven by the worm wheel.
Such as the self-locking worm mechanism used in its heavy
machinery, its reverse self-locking can play a role in safety
protection.

Applications
New energy is divided into: solar energy, tidal energy, wind
energy, etc. Hangtuo rotary drive device is widely used in these
industries and recognized by technical engineers.
Solar: Large slewing rings and drive units are available for solar
installations that meet the requirements of this field of use in
terms of corrosion protection, temperature fluctuations and precise
control of the adjustment angle. Our products ensure that the cells
of photovoltaic devices are aligned optimally with the sun at all
times.
Wind energy: Our efforts in the field of renewable energy make
Airtop slewing drives a reliable partner for all major wind energy
equipment manufacturers. And this starts from the very beginning of
the industry. Thanks to intensive research and development work,
our products are used in onshore and offshore equipment worldwide.
We are committed to enabling our products and our customers to
contribute to an environmentally friendly future.
