VE9 Compact Worm Gearbox Slewing Drive With 24V Gearbox Reducer For
Solar Energy
Hourglass Worm Gear Slew Drive Description
A slew drive is designed to handle radial or axial loads using high
rotational torque. Equipment for mining, construction,
metalworking, PV solar energy, Concentrated Solar Power and other
applications that require unrelenting strength combined with
faultless precision use slewing technology for safety and accuracy.
Single axis slew drive used in flat single axis tracking system,
which bracket is a north-south arrangement, east-west tracking
system. According to the astronomical algorithm, the slew drive
driven by motor will bear high torque to drive the whole system, so
that the system can track the azimuth of the sun, as far as
possible to improve the sun on the surface of the photovoltaic
module irradiation, and thus increase the power generation.
This is mainly based on the design principle of the tracking
system, due to the impact of the rotation of the earth, for a fixed
location on the Earth, the sun cycle throughout the year, its
illumination angle is also constantly changing. The solar tracking
system is installed to keep solar panels up to track the sun and
increase the amount of solar radiation received by photovoltaic
arrays, thereby increasing the overall capacity of solar
photovoltaic power generation systems.
