3 Inch IP66 Small Enclosed Slew Drive For Tilted Solar Tracking
System
Tilted Solar Slew Drive Description
A slew drive system is a compactly constructed unit which consists
of a worm, gear, base, house, bearings and other accessories. This
unit brings the advantages of a gear and a worm into one unit. Our
SE drives offer an IP66 rated enclosure that nearly complete
protection from environmental particles such as dust, dirt, sand,
and even water. Our testing equipment ensure our products a 30-year
field lifetime.

Different motors (220VAC, 380VAC motors, 12VDC, 24VDC, 48VDC
motors, servo motors and stepper motors) can be designed according
to customer's requirement.
DC Motor
1. Adopt Dual supporting structure for output shaft so that the max
torque of gearbox is increased a lot.
2. Sun wheel and planetary wheel are connected by spline which
increase the max torque of gearbox and lengthen the life.
3. We use helical gear at input stage which make the noise low anf
run smoothly in high speed. The inner gear ring is separated so that we can make more ratio and
the design is flexible. Gearbox and motor are located by a seam fix by screw in axial which
increase the matching precision and reduce noise.
4. We use rolling pin holder inside planetary wheel.we use rolling
pin grinding instead of sliding grinding so the life of gearbox is
much longer.
5. Double supporting structure; Internal grinding on inner bore of
planetary gears making the inner bore roundness less than
0.003mm;running by rolling instead of sliding; HRC60 gear surface
precision scraping;The adopting of all these technoligies ensure
the super quiet and steady operating and a long life time over
10000 hours.
