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.
