Heavy-Load Slewing drive
Heavy-Load Slewing drive


Slewing drive is 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.


Slewing drive is able to sustain more axial load, radial load and tilting moment.Turntable or frame rotate at azimuth and elevation driven by slewing drive.



Slewing drives usually come with different applications. For instance, according to the raceway diameter of the slewing ring, a slewing drive can be classified into WD-080, WD-0130, WD-0170, WD-0223, WD-0343, WD-0419, WD-0478, and WD-0625 series, etc. in the international market. In the model, W and D refer to Worm and Drive respectively. 

In China, most slewing drive manufacturers divide slewing drive into SE3, SE5, SE7, SE9, SE12, SE14, SE17, SE21, and SE25 series, etc. In the model, S and E refer to slewing and enclose respectively and the number refers to the raceway diameter of the slewing ring in inch.


When a slewing drive is used in solar energy industry, users have to choose an ideal one according to the actual area of solar panels. Broadly speaking, SE3 slewing drive is suitable for solar power system coming with 3- 5 m2 solar panel, SE7 for 10-17 m2 solar panel, SE9 for 18-30 m2, SE12 for 31-45 m2, and SE14 for 46-60 m2. These are provided for your reference. For more specific and detailed information, please contact us directly.

Application

●For Solar:It is designed in solar tracking system and improve power generation efficiency.

●For industrial usage: Mainly used to drive two relative rotating objects in 360°.



Advantages

lyjw Slewing drive designed with hourglass worm shaft which provides more tooth contact and higher torque.

Service life is increased by gear and raceway harden.

Product performance is tested and ensured product quality.
