Dual worm slewing drive is a brand new slewing drive product, which consists of a shell, worm gear sleeve, worm, motor, and other components. Unlike a single worm, under the premise of the same shape and size, a dual worm slewing drive has a compact structure history, better load capacity, and much more output torque than a single worm slewing drive. Compared with a single worm slewing drive, a dual worm slewing drive still has the characteristics of modularization, safety, and simplified clamp design.

In this device, 2 worms are used to drive the external ring gear of the slewing ring. The inner circle is fixed above the seat ring of the base, and the first shaft shell and the second shaft shell are symmetrically arranged on the outer side of the seat ring of the ground. The axis lines are perpendicular to each other in space; the first worm is installed in the first shaft housing; the second worm is installed in the second shaft housing. The first worm and the second worm are both meshed with the outer gear ring. The translational forces of the 2 worms offset each other. At the same time, the gap between the worm and the outer ring gear can be “eliminated” to achieve precise positioning of the rotation angle of the external ring gear. The dual-worm slewing drive has a simple structure and practical design and can be widely used in engineering machinery, construction machinery, solar photovoltaic, and other industries.
