Worm Gear Slew Drive Drived By Electric Motor And Gear Box For
Solar Tracking System
Product Description
The Slewing Drive, also called slewing ring bearing, is a kind of
product able to withstand large axial loads with very low speed.
And depending on the type also are well suited to absorb tilting
moment. Slewing rings are available in industrial models, in which
the rings are made from forged steel and hardened ball tracks are
also implemented. As technology has improved, more slewing drives
are using hourglass worm technology, in which the worm is shaped to
engage more teeth in the gear. This increased tooth engagement
results in greater strength, efficiency and durability.
The slewing drive uses standard worm technology in which the worm
on the horizontal. The speed ratio of the shaft depends on the
relationship between the number of threads on the worm and the
number of teeth in the worm gear or gear. They are standardized
products for specific industries such as the solar industry and
mobile applications such as excavators. The worm are powered by an
electric motor or hydraulic motor, whether or not combined with an
additional planetary gear box, worm gear box etc.

Application of the Slew Drives
With excellent rotation accuracy and torque, our slewing plays an
important role in the field of artificial intelligence, such as
robots, dust-free spray shops, robotic arms, etc. We have developed
and designed many personalized design solutions, A complete
rotation solution is given in combination with specific operating
conditions.
Our slewings are used both in heavy equipment, such as armored
vehicles, and in sensitive optical equipment. They are
characterized by robustness, precision and reliability.
Our slewing is used in the construction machinery industry, and has
been well received by customers at home and abroad. The slewing
bearing of construction machinery is a special force-transmitting
base in construction machinery that simultaneously bears axial
force, overturning moment, radial force and requires two parts to
rotate relative to each other. The slewing bearing application in
the machinery industry is more common, such as: hoisting and
unloading machinery, mining machinery, port machinery, etc.
