9 Inches IP66 Worm Gear Slew Drive For Horizontal Single Axis Solar
Tracking System
High Torque Slewing Drive Description
High torque lew drive, with low speed, is a kind of integrated
drive power source of fully rotary deceleration transmission
mechanism, it takes the slewing bearing as the transmission
actuator and the mechanism attachment, by attaching the active
part, the driving source and the shell to one ring in the inner and
outer ring of the slewing bearing, while the other ring as both the
transmission actuator and the connecting base of the driven working
parts. In this way, by using the the characteristics of slewing
bearing as the fully rotary connector to configure the drive power
and the main drive parts effectively, making it a set of rotary,
deceleration and drive functions and at the same time with simple
structure, general type of deceleration transmission mechanism of
easy manufacturing and maintenance.

Q&A
Why Use a Slewing Drive Tracking System
The design principle of the photovoltaic tracking support system is
not complicated. Since the sun's irradiation angle is always
changing, traditional fixed photovoltaic panels are no longer "dead
things" after adopting tracking technology. Instead, it can chase
the sun like a sunflower, increasing the amount of solar radiation
it receives, thereby increasing the power station's overall power
output. It is conservatively estimated that tracking technology can
increase the power generation of photovoltaic power plants by 20%
to 30%. The traditional fixed photovoltaic panels have the lowest
power generation efficiency, and the photovoltaic panels of
single-axis and dual-axis brackets and auxiliary systems are indeed
relatively high. Many power stations are built in areas with
relatively harsh environments. Strong wind, sand and snow have
brought trouble to the operation and maintenance of the power
station. With tracking technology, photovoltaic panels can adjust
the angle at any time, and the power station will no longer be
vulnerable to severe weather. In addition, thanks to the
single-axis and dual-axis supports, the photovoltaic power station
with tracking system can be more closely integrated with
agricultural production, and can operate flexibly in the
environment of ponds, mountains and wasteland, which has advantages
over traditional power stations.
