The straight worm structure is adopted, and the gear part of slewing bearing is quenched by isothermal and high frequency, the tooth part has high hardness and good wear resistance.The contact area between the turbine and the worm is large, the operation is stable, the transmission torque is large, the transmission efficiency is high.
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.
Radial load: Load vertical to the axis of slewing bearing
Axial load: Load parallel to the axis of slewing bearing
Holding torque:It is the reverse torque.When the drive is rotating reversely, and parts are not damaged,The maximum torque achieved is called holding torque.
Self-locking: Only when loaded, the slewing drive is not able to reverse rotate and thus called self-locking.


For worm shaft, slewing gear and casting housing Coresun Drive makes 100% finished product inspection.
Coresun Drive processes the Slewing Drive Motor metallographic testing to ensure the quality of raw material and makes the salt &spray testing to make sure the anti-corrosionperformance.
