SDE3 Envelop Worm Gear Slew Drive Gearbox IP 66 For Dual Axis Solar
Tracking System
Description
For slewing drive, there are nine (9) different sizes available
from 3" to 25" with more than 60 models to meet both regular and
precise tracking requirements in PV system like oblique tracking
system, flat single tracking system, CPV and solar thermal power
tracking fields.
Advantages
1) Higher output torque and holding load
2) Top tracking precision
3) Strong corrosion resistance and sealing effective
4) ISO/CE certified
5) IP66
6) Self-locking
7) Backlash: less than 0.01 degree
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
