SDE / PDE 3 Inch Worm Gear Slew Drive High Precision For Dual Axis
Solar Trackers
Worm Gear Slew Drive Description
Solar tracker comprises of several parts including sun tracking
algorithm, control unit, positioning system, drive mechanism
system, sensing devices, wind guard, tubes, and rods. Growing
demand for energy supplemented by fluctuating fuel oil prices,
increase in efficiency of solar panels by the use of solar trackers
and increased product demand are expected to bolster the overall
solar tracker market growth.
Slewing drive is a main part in solar tracker. By adopting slewing
bearing as its core component, slewing drive can bear axial force,
radial force and tilting moment simultaneously. Dual axis solar
tracking system is one of the applications of slewing drives.

Features
1. High backholding torque to improve the solar tracking system's
safety
2. Enveloping worm drive inside
3. Multi tooth contact to ensure high load
4. Self-locking function
Dual axis slewing drives are used in dual axis solar trackers,
heliostats, concentrated photovoltaics (CPV), and satellite
antenna. By applying a dual axis slewing drives on a solar system,
the panels will always be oriented towards the sun, no matter the
season, time of the day or latitude of the regions. It can let the
project owner gain more electricity capacity up to 40%. And thus
more yield.
Q&A
1. How can i choose?
Please specify the wheel diameter size, width, voltage, power and
no-load speed of the required motors.
2. Could I take samples to test quality and market in advance?
Sure, welcome to take samples to test our quality and service.
3. What's the total cost for samples?
Total sample cost= sample cost + freight
We will give you the best shipping cost after you choose the
suitable gear motors
