The slewing drive is a gearbox that can safely hold radial and
axial loads, as well as transmit a torque for rotating.
The rotation can be in a single axis, or in multiple axes
together.Slewing drives are made by manufacturing gearing,bearings,
seals, housing, motor and other auxiliary components and assembling
them into a Únished gearbox.
Slewing drive is widely applied in modular trailers, cranes, timber
grab equipment,aerial working platform, solartracking systems wind
power systems, etc.
slewing drive is suitable for high-latitude areas and the eÜciency
of power generation will be increased over 35%,which signiÚcantly
improve the eÜciency of solar power generation system.
For horizontal single-axis solar tracking system, the main shaft of
solar panel will adjust the angle to precisely track the
declination angle. This kind of slewing drive is only applied for
low latitudes area.
By adopting slewing bearing as its core component, slewing drive
can bear axial force, radial force and tilting moment
simultaneously. Slewing drive is widely applied in solar tracking
systems.
The solar tracking system is divided into Horizontal single-axis
solar tracking system, Tilted Single-Axis Tracker and Dual axis
solar tracking system.
The slewing drives which are used in solar tracking systems are
mainly single axis (SE series), dual axis (SDE series) and vertical
type (VE series). And the most common used models are SE3, SE5,
SE7, SE9; SDE3 and VE7, VE9.
Solar Tracking System Enclosed Housing Slew Drive With tilting
moment capacity
Slewing drive’s mainly consists of a slewing bearing, a worm
shaft&motors(AC,DC, hydraulic). It can also bear axial load,
radial load and tilting moment.The main advantage is easily to
install,maintain and save installation space.
SE Enclosed Housing Slew Drive help power movement across
industries and are perfect for situations requiring both
load-holding and rotational torque from the same gearbox. Typical
applications include solar trackers, wind turbines, satellite and
radar dishes, truck cranes, man lifts, utility equipment, hydraulic
equipment attachments, oil tool equipment, tire handlers, digger
derricks, and automotive lifts.
Enclosed Housing Slew Drive provide load support and controlled
rotational torque in both single and dual-axis solar trackers.Our
in-house solar tracker is used for accelerated life cycle tests of
applied torque, radial, and axial loads, and overturning movement.
There is a special weighted cage structure so that we can mimic up
to 120 square meter PV panel.
SE Enclosed Slew Drives help power movement across industries and
are perfect for situations requiring both load-holding and
otational torque from the same gearbox. The slewing drive is a
modernized take on the worm drive mechanism that dates back many
centuries and was widely used during the Renaissance Era. Pappus of
Alexandria (3rd century AD), a Greek mathematician is credited for
an early version of the endless screw, which would later evolve
into the worm drive.
Slewing drives are commonly used mechanical devices, found today in
applications such as construction cranes, solar tracking systems
and industrial equipment. The basic technology found in these drive
mechanisms, however, is very old dating back to Ancient Greece, and
employed by Leonardo da Vinci in many of his Renaissance
inventions. Modern slewing drives represent the modern evolutions
of an ancient and highly effective basic machine, the worm drive or
endless screw.
A quality modern slewing drive includes a sound mounting structure,
a slew bearing, rotational movement and power controls to
facilitate perfect motion. In operation, the drive converts axial
movement (force exerted on an axis) into radial/rotary torque,
allowing the rotation of greater loads with more accuracy, while
also enabling geared torque amplification.
The slewing drive does this by meshing the grooves of a horizontal
screw (the worm) with the teeth of a gear placed perpendicular to
the screw. The gear rotates as the screw turns, and the screw’s
axial movement force is then transmitted to the radial gear as
magnified output torque.
While the basic idea behind the slewing drive is not new, the
modern incarnations of this device feature many relatively recent
innovations. Kinematics’ patented hourglass screw design, for
example, increases the number of gear teeth that can be engaged
with the worm grooves at once, greatly improving force transition
over standard worm designs by meshing much more efficiently with
the radial gear. This, in turn, significantly increases the drive’s
survivability load, positioning accuracy and rotational smoothness.
Enclosed in a rugged and tested enclosure to protect the mechanism
from water, dust, dirt and other particulate contaminants, the
resulting Kinematics slewing drive gearbox delivers a powerful
means of creating accurate rotational force in many of the world’s
most demanding applications.
By adopting slewing bearing as its core component,slewing drive can
bear axial force, radial force and tilting moment simultaneously.
Slewing drive is widely applied in modular trailers, all types of
cranes, aerial working platform, solar tracking systems and wind
power systems.
Electric and planetary gearboxes can be designed according to
customer's requirement.Slewing drive has the advantage for saving
space in facilities,max load capacity in a compact design,extensive
lifespan, reduced maintenance costs.

The vertical slewing drive is generally installed perpendicular to
the ground and is widely used in various photovoltaic power
generation projects, such as trough power generation. Sometimes the
drive end can be installed a vertical slewing drive, and the
non-drive end can choose to use a bearing housing.For example, the
drive of the flat single-axis system is widely used in this kind of
structure. PE series slewing drive is our high precision type slew
drive, usually we have three precision grades: I≤0.05°,II≤0.07°and
III≤0.09°and this model with enclosed housing, it can prevent dust
and water from entering the inside. If customer intends to use
solar panels,its can handle 18-30m2 solar panels area.
Solar tracker comprises of several parts including sun tracking algorithm, control unit, positioning system, drive mechanism system, sensing devices, wind guard, tubes, and rods. Growing demand for energy supplemented by fluctuating fuel oil prices, increase in efficiency of solar panels by the use of solar trackers and increased product demand are expected to bolster the overall solar tracker market growth.
