Reliable Vertical 5 Inch Single Axis Slew Drive With Stepper Motor
For CSP Station
Single Axis Slew Drive Description
Specifications: Our base model sizes deliver performance ranges
from 1,500 Nm to 11,200 Nm of holding torque, 100Nm to 20,000 Nm of
output torque, 5000 Nm to 89,000 Nm of tilting torque, and gearbox
reduction ratios of 30:1 up to 150:1. By attaching a planetary
gearbox, the gear ratio could be even higher. The drives can be
mounted horizontally, vertically, or on a combination of multiple
axes.
Reliability: Our SDE dual-axis slewing drives are assured for a
30-year field life time of precise 3D positioning. SDE drives
create an efficient and reliable solution in a single drive. We
qualify all of our components and raw materials using standards set
by ISO 9001, CE certifications to maximize field life.
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. Learn more about
hourglass technology.
Applications: The most common slewing drive application for the
dual-axis slewing drives are dual-axis solar trackers, such as
heliostats and concentrated photovoltaics (CPV), and satellite or
radar dishes. Other applications such as automotive lifts, robotic
arm positioners, and stage equipment.

Features
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
