SE3 Zero Backlash Worm Gear, Hourglass Worm Slew Drive For Solar
Tracking System
Worm Gear Sets Description
SE single axis slewing drive is a critical component in both single
axis solar tracking system and dual axis solar tracking system.
Besides, with its perfect and high backlash, it can also applied in
CSP and CPV system, wind energy, antenna which need higher
backlash.
What is Single Axis Solar Trackers
A single-axis tracker orients PV modules along one axis of
rotation, moving horizontally from east to west as the sun moves. Moving these PV modules requires the
reducer offer both load-holding and rotational torque – something
only a highly specialized slewing drive can offer. Trackers applied
slewing drives technologied with hourglass worm can engage a
greater number of teeth on the pitch line of the gear ring, offer
the maximum amount of strength, durability and performance. This
ensures the tracker has the longest possible field life with the
least amount of downtime or maintenance cost.
What is Dual-Axis Trackers
Dual-axis trackers rotate side to side and up and down, enabling
even more precise tracking of the sun's movement.These slewing
drives enable a higher energy output than single-axis systems.
Given that they employ two degrees of freedom, utilizing strong and
powerful slewing drives is even more important for reliable and
continuous functionality in the field.

Advantages
1. Rotation 360 degrees
2. Driving motor connected to the left or right side
3. During installation, it is not necessary to adjust the gearing
clearance; this is already set by the producer before factory
4. Grease had been filled before factory
4. Simple installation and low maintenance
5. Rational space utilization
6. The gear is self-locking; therefore a brake is not necessary
7. Easy and fluent method of starting and stopping
8. High tilting torque, suitable for horizontal installation
