Description of slewing drive
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.
SDE 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 s,
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.
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 finished 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 effciency
of power generation will be increased over 35%,which significantly
improve the effciency 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, SDE7 , VE7, VE9.
Reliability
Our SDE dual-axis slewing drives are assured for a 30-year field
life time of precise 3D positioning. SDE drives create an efficient
and reliable solution in a single drive. We qualify all of our
components and raw materials using standards set by ISO 9001, CE
certifications to maximize field life.
Performance
Our slew drives use patented hourglass worm technology to give
maximum control and movement support. Our worm gears engage 5 to 11
teeth on the pitch line of the ring gear from the hourglass screw,
which is higher tooth engagement than standard worms, giving the
gearbox greater stability and strength. Learn more about hourglass
technology.
How to choose the proper size of slewing drives?
Choosing a proper size of the slewing drives in order to avoid from
not only performance lack or performance surplus is play an
important role in achieving cost effective solutions.
Please give us the following information in order to select a
suitable slewing drive:
1. the application
2. the output toque required. If you do not have a clear idea of
that data, just tell us the load, for example, the weight of panels
and the mounting brackets on our slewing drive.
3. the load dimensions and the biggest wind in your area in the
past 10 years which are used to calculate if the drive we
recommended could bear the maxium load when there comes the big
wind.
4. the output speed you required which will help us to recommend
the suitable motors for you.
5. other informations such as backlash, IP grade demand etc
Our dual axis slewing drives are listed below, for more detailed dimensions and parameters, please refer to our
sales drawings.
