SE3 Enclosed Solar Tracker Slew Drive With 24VDC Planetary Gear
Motor And Hall Sensors
Enclosed Solar Tracker Slew Drive Description
The worm drive gearbox is suitable for applications which demand
slow rotation with a continuous or cyclical movement capable of
handling combined loads. The product is with standard dimensions
for coupling an electric or hydraulic motor as well as coupling a
whole system to equipment.
Due to its compactness, high rigidity and other mentioned
advantages, a worm drive system is used in varying equipment such
as mobile assembly platforms, satellite system, hydraulic loading
cranes on haulage vehicles, small marine cranes, extendable
rotating ladders, in wheel units of large marine portal
transporters.
A slew worm drive system is a compactly constructed unit which
consists of a slewing ring, base plate and worm. This unit brings
the advantages of a slewing ring and a worm into one unit.

Remarks
1. Different motors (AC, DC, and Hydraulic) can be designed
according to customer's requirement.
2. Shaft opposite to motor can choose to be hex head or not hex
head.
DC Motor Specification
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.
