Dual Axis High Precision Slew Drive Gearbox For Concentrated Solar Power Station
Dual Axis Slew Drive Description
Concentrated solar power systems, or CPV for short, generate solar
power by using mirrors or lenses to concentrate a largearea of
sunlight, or solar thermal energy, onto a small area. Electricity
is generated when theconcentrated light is converted to heat, which
drives a heat engine connected to an electrical powergenerator or
powers a thermochemical reaction
The ZSDE series designing is absorbs the advantages of ZVE and ZSE.
The Azimuth and Elevation 3D direction rotating at the same time.

Performance
Our slew drives use patented hourglass worm technology to
give maximum control and movement support. Our worm gears engage 5
to 11 teeth on the pitch line of the ring gear from the hourglass
screw, which is higher tooth engagement than standard worms, giving
the gearbox greater stability and strength.
By adoping hourglass worm, the drives have the following features:
1) Higher output torque and holding load
2) Top tracking precision
3) Strong corrosion resistance and sealing effective
How to choose the proper size of slewing drives?
Choosing a proper size of the slewing drives in order to avoid from
not only performance lack or performance surplus is play an
important role in achieving cost effective solutions.
Please give us the following information in order to select a
suitable slewing drive:
1. the application
2. the output toque required. If you do not have a clear idea of
that data, just tell us the load, for example, the weight of panels
and the mounting brackets on our slewing drive.
3. the load dimensions and the biggest wind in your area in the
past 10 years which are used to calculate if the drive we
recommended could bear the maxium load when there comes the big
wind.
4. the output speed you required which will help us to recommend
the suitable motors for you.
5. other informations such as backlash, IP grade demand etc
Packaging and Shipping
Plywooden box.
The slew drive is with small dimension but heavy weight weight, it's not cost effective shipping by sea while the express shipping the cost-effective way, our logistitic staffs will asked TNT, DHL, UPS, FEDEX, to compare the express price in order to find the most cost effective way.
If in bulk order in the future, we recommend ship by sea.
Note:
Express: door to door, just need to pay the import tax if required by the custom.
By air or by sea: factory to destination airport/sea port, need pay destination fee charged by the airport(the destination fee is always charged by per B/L regardless of the package is big, small, heavy or light, in gerneral 200~400 USD per cargo) and import tax if required by the custom.
By train: sometimes the shipping price is the same as sea but taking less shipping time than sea, we will take this shipping way into consideration if the goods are in urgent need by our clients.
