Fenghe’s worm gear and worm rotary drive includes two categories: cylindrical worm and envelope worm, of which cylindrical worm is suitable for medium speed.
Heavy-duty applications while the enveloping worm is suitable for low-speed heavy-duty and high-precision applications, the worm gear and worm rotary drive can be self-locking, in the power movement
The domain can provide basic security and further simplify the overall design of the equipment, and is an excellent industrial accessory.

Double worm slewing drive
Double worm slewing drive is a brand new slewing drive product, which consists of outer casing, worm gear ring, worm, motor and other components.
Advantages compared to single worm slewing drives:
- The double worm slewing drive still has the characteristics of modularization, safety and simplified host design.
- Different from the single worm, under the premise of the same external dimensions, the double worm rotary drive has a more compact structure, better load capacity, and output torque far exceeds that of the single worm rotary drive.
- The double worm slewing drive abandons the core component slewing bearing in design, and forms a double-row space cross-roller type slewing bearing in theory through the outer casing and the worm gear contained within it, and meshes with the worm gear through two worms in the casing. In order to achieve rotation, to ensure that while achieving higher bearing capacity, it can also generate higher output torque.
