Slewing Drive With Stepper Motor And Encoders For High Presision
Solar Tracking System
Slewing Drive Description
Horizontal single-axis system with single-axis slewing drive
The single-axis tracking system is suitable for use in areas with
latitudes below 30 degrees, and can increase power generation by
20%-30%.
Inclined single-axis system with single-axis slewing drive
Oblique single-axis tracking and vertical single-axis tracking are
suitable for use in areas with latitude higher than 40 degrees,
which can increase power generation by 25%-35%.
Dual axis tracking system using dual axis slewing drive
The system has an axis of rotation in two directions. The panels
can be made to track the sun at the same time in the sun's azimuth
as well as in its altitude. So as to achieve that the panels remain
perpendicular to the sun's rays. Dual-axis tracking is suitable for
use in areas with latitudes higher than 40 degrees, which can
increase power generation by 35-45%.

About Us
You can order a basic type (open gear) or a fully enclosed type. We
also offer a two-axis slew drive (single rotary drive rotates
simultaneously in both directions) and a single-shaft dual drive
(two drive worms drive the same slewing bearing on a single shaft).
Typical slew drive applications include solar power plants, wind
turbines, truck cranes, aerial work vehicles, utility equipment,
hydraulic equipment, petroleum equipment, wheel steering equipment,
excavators, and automatic lifting equipment. There are many other
applications that have not been exhaustively listed, as the slewing
drive is the best choice for applications that offer high loads and
high torque on the same transmission.
We produce many different types of slew drives and offer many types
of slew drives and drive components. Our slew drives can be
self-locking or back-drive. The self-locking slew drive does not
reverse when the reverse force is transmitted from the slewing ring
to the worm, and there is no need to install a separate brake.
Instead of self-locking, it can be driven in reverse. For hydraulic
applications, we supply hydraulic motors to our customers. For
electric equipment, we can supply gearboxes and various motors for
our customers.
