Hourglass Worm Gear Solar Small Slew Drive For Single Axis Tracking
System
Worm Gear Enveloping Slewing Drive
The rotary motion of the slewing drive is driven by a hydraulic
motor, electric motor, stepper motor or a servo motor. It is easy
to find a matching hydraulic motor or DC electric motors in the
market, and it also conforms to industry standards, which can save
a lot of time.
For the motors, however, some device adapters are also required
when come to connect the motors to the slewing drives' worm shaft.

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
Applications
SE single axis horizontal slewing drive is a critical component for
both single axis solar tracking system and dual axis solar tracking
system. Besides, it can also applied in CSP and CPV system, wind
energy, robot etc.
Single-Axis Tracking System
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 that the reducer offer both
load-holding and rotational torque – something only a highly
specialized slewing drive can offer. Trackers applied slewing
drives that engage a greater number of teeth on the pitch line of
the gear ring will 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.
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.
