Introduction:
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 requirements. Slewing drive has the advantage for saving space in facilities, max load capacity in a compact design, extensive lifespan, and reduced maintenance costs.
Glossary
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.
--Customer can choose the motor according to our already designed slewing drive connect dimension.
--We can design the connect structure 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.
Standard Model Slewing Drive:
A. Enclosed housing (SE Series)
B. Open Housing (S Series)
C. Special Type


Note:
1. Different motors(AC, DC, Hydraulic) can be designed according to customer's requirement.
2. Shaft opposite to motor can choose to be hex head or not hex head.

Slewing drive introduction
1. Introduction of LBD slewing drive

LBD Slewing Drive movement can reduce power consumption, since the security role. In addition to the field of use in the daily solar power systems are usually used for Special vehicle, heavy-duty flat-panel truck, container cranes, truck mounted crane, automobile crane and aerial vehicles, cranes, gantry cranes, small wind power stations, space communications, satellite receiver, etc...The Slewing Drive in the solar photovoltaic industry, the general configuration DC planetary reduction motor or AC geared motors; Main configuration of the hydraulic motor as a power-driven construction machinery
LYHY Slewing Drive principle of the large transmission ratio of the deceleration device to transmit motion and power between the two axes staggered in space. The Slewing Drive transmission is usually the case of the main components of the worm and wheel bearings, shell, and the power source
As the core component of turntable bearings, can withstand the axial load, radial load and overturning moment. 

2. Structure
Slewing drive can be divided into two different structures as per different applications. 
Light load slewing drive
Heavy load slewing drive
The dimensions of slewing drives include 3 inch, 5 inch, 7 inch, 9 inch, 12 inch, 14 inch, 17 inch, 21 inch and 25 inch. 

3. Features: 
Slewing drive is a special bearing. And a slewing drive usually consist of slewing bearing, worm shaft, housing, bearing, motor and so on. Motor drive the worm shaft, the outer ring of slewing bearing will rotate, the outer ring output the torque through flange while the inner ring of slewing bearing is fixed in housing. 
LBD Slewing Drive and rotary products, compared with the ease of installation, ease of maintenance, Installation space savings advantages to a greater extent. 

4. Application: 
Slewing drives are widely used in aerospace area, solar power systems, wind turbines, satellite broadcasting system, and engineering machinery like truck cranes, and man lifts, etc. Recently years, it has been prosperously used in photovoltaic power generation systems, special vehicle, heavy-duty flat-panel truck, container cranes, truck mounted crane, automobile crane and aerial vehicles, cranes, gantry cranes, small wind power stations, space communications, satellite receiver, etc.
