Heavy Load High Quality Slewing Drive Used for Forestry Machinery 

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.

Description
There are no special limitations of mounting angles and positions of this series of products.  It can be mounted horizontally, vertically and inclined.  Enclosed slewing drives are assembled of enclosed housing, slewing bearing, worm shaft and other parts.  Users can choose electric motors or hydraulic motors as the driving power.  It can slew 360 degrees clock-wise or otherwise.  The slewing drive is compact and it is also easy to mount and maintain in comparison with other types of driving devises.
 
Features
It adopts enclosed design and the protection level can reach IP65.  It can effectively prevent dust, rain and other hostile environments.  It suits field usage such as desert, alpine and other hostile environments.
1.Products are easy to mount and maintain.
2.The design and mounting dimensions are international or domestic universal dimensions.  It is easy for the users' replacements in the future.
 
Applications
1.This series of products are widely applied in the turning parts in construction machinery and solar power industries.
2.The azimuth and elevation drivers of solar tracking systems
3.The rotations of turntables or cranes in various types of construction machinery
4.The rotating parts of industrial equipments such as welding positioners

Tilting Moment Torque: Torque is the load multiplied by distance between the position of load and the center of slewing bearing. If the qorque 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.
