Product Description

Coresun Drive @ Slewing drive is a kind of all-round slewing decelerating transmission mechanism integrated with driving power source. It uses slewing ring as driving follower and mechanism attachment. By attaching the driving part, driving source and cover on one of the inner and outer rings of slewing ring, the other ring is regarded as both the driving follower and the connecting base of the driven working parts. In this way, slewing ring is used It is the feature of all-round rotation connecting piece. It is a general-purpose decelerating transmission mechanism which integrates the functions of rotation, deceleration and driving, but also has simple structure and convenient manufacture and maintenance.

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.

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.

Salt spray test is the method we must take to confirm the corrosion resistance and protection level of the product.The casting housing,worm shaft,slewing bearing and end cap and all of the parts should be tested.
