Totally enclosed housing slew drive High reliability For HCPV & PV
designed worm motor slewing drives PE3C/ZE3C with Hydraulic motor
Slewing Drive
By adopting slewing bearing as its core component,slewing drive can bear axial force, radial force and tilting moment simultaneously. Slewing drive is widely applied in modular trailers, all types of cranes, aerial working platform, solar tracking systems and wind power systems.
Electric and planetary gearboxes can be designed according to customer's requirment.Slewing drive has the advantage for saving space in facilities,max load capacity in a compact design,extensive lifespan, reduced maintenance costs.
Glossary
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.
Hourglass worm
Hourglass worm: Compare with traditional worm, hourglass worm can withstand a survivability load that is four to nine times greater.As the special hourglass shape of the drive allows more teeth to be engaged at one time,enabling much higher torque endurance.It can increase the durability, precision,and efficiency and maximum load capacity in a compact design.
--Customer can choose the motor according to our already designed slewing drive connect dimension.
--We can customized the connection dimension according to customer's motor connect dimension.
--We can help to provide the whole parts with Hydraulic motor, DC motor, AC motor, Stepper or Servo motor.

Friendship Recommendation
It is advised to mount the slewing drives referring to attached drawing upside in solar applications for better protection.
For other applications, the mounting directions shall be based on the evaluation of the protection level and it shall be better for better protection.
It is advised to mount the slewing drives upside down on the azimuth axis in solar applications for better protection and add protection for the elevation axis.
For other applications, the mounting directions shall be based on the evaluation of the protection level and it shall be better for better protection.
