Worm And Gear Dual Axis Slew Drive, Small Backlash For Precision
Applications
Worm And Gear Dual Axis Slew Drive Description
Slewing drives of worm gear construction can be used for a wide
range of solutions for steering and rotary applications. We supply
slewing drive products according to your requirements and can also
provide you with customized system solutions.
The slewing drive device has a reverse self-locking function, which
greatly improves the stability and safety factor of operation. In
addition, the worm is a secondary enveloping toroidal worm, which
has more contact with the gear, which enhances the strength and
stability of the whole machine. The products are designed to carry
heavy loads and withstand high strength without breaking. We can
provide torque reports and 30-year life test reports according to
customer needs.

Application
The application field of worm gear slewing drive is often used in
the case of two shafts staggered, large transmission ratio, small
driving power or intermittent operation. The slewing drive can be
applied to the main engine that does circular motion, such as crane
turntable, rotating machinery, and some machinery that works in a
circle. After the product is put into production, it can be widely
used in the field of construction machinery, such as aerial work
vehicles, truck cranes and new energy fields, such as solar
photovoltaic power generation, wind power and solar thermal system
power generation. There are other fields such as automation,
machine tool manufacturing, space communication, etc., and the
market potential of products is very huge.
