How Do Slew Drives Work?

The mechanics behind it is built on the concept of a worm wheel where a slewing ring with external teeth is meshed with complementing worm gear with a predefined gear ratio. Internal components are contained and assembled inside a cast iron or aluminum housing for protection and installation.The unique design of a slew drive allows it to utilize two perpendicular planes transmitting high output rotational torque with a relative speed ratio to its inputs. As the worm gear rotates through a low input torque on the horizontal plane, its hardened teeth translate rotational motion onto the external slewing teeth. This force creates a rotation around the perpendicular axis of the slew drive through the slewing outer ring.A worm-wheel design allows a wide range of low torque inputs to the slew drive to transmit or hold high torque applications. Slewing drives can be found across several constructions and heavy machinery equipment. The versatility and weight allow slew drives to act as an immediate solution to rotary-related issues.

Applications of Slewing Drive

Slew drive can be widely used for 360° rotating and speed shifting, ample torque smoothly transmission, high precision matching or compacted mechanism is mainly relied on slew drive, for its particular solution and widely application below:

• Heavy loading gantry crane

The slewing drive has changed the traditional mode of heavy loading gantry cranes in this field, significantly reducing operating and maintenance costs. It has been adopted by more and more host manufacturers of its effectiveness.

• Aerial work vehicle field

The slewing bearing motivates slewing drive, which has developed rapidly and has obvious advantages in this field.

• Heavy loading flatbed truck (beam truck)

Due to the heavy load, duplex worm slew drives widely provide ample output torque.

• Port cranes

While using a slew drive to fulfill the loading moment, the conventional hydraulic cylinder is another way to modify the rotating slewing ring.

• New energy field

With the support of national policies, the prospects of the rotary drive in this field are very impressive.
