High Torque Slewing Gear Reduction For Truck Crane

Heavy load worm gear slewing ring bearing

High holding torque and tilting moment torque

Slewing Drive Parameter Meaning

1) Tilting Moment Torque: Torque is the load multiplied by distance between the position of load and the center of slewing bearing. If the torque generated by load and distance is greater than the rated tilting moment torque, slewing drive will be overturned.
2) Radial load: Load vertical to the axis of slewing bearing.
3) Axial load: Load parallel to the axis of slewing bearing.
4) Holding torque: It is the reverse torque. When the drive is rotating reversely, and parts are not damaged.
5) The maximum torque achieved is called holding torque.
6) Self-locking: Only when loaded, the slewing drive is not able to reverse rotate and thus called self-locking.

Rotary drive slewing drive worm gear is a perfect combination of turbine worm products, worm ring surface envelope form, its tooth contact area is large
The enveloping worm structure is adopted to drive the worm wheel and worm gear, and the tooth meshes more closely

We offer the slewing drive slewing gear from 2 inch to 32 inch as customized solution
