SE3 Worm Gear Slew Drive Enclosed Solar Tracker Slew Drive With
24VDC Gear Motor
Description
SE slew drives are mainly used in solar tracking system,
construction machinery.
Because of their multiple uses, slewing drives come in a variety of
model sizes, performance ranges and mounting characteristics. The
drives are well suited for applications that require both load
holding and rotational torque from the same gear box. They can also
be made with dual axes of rotation, (turning axes at the same time)
or with dual drives on the same axis, (two worm threads driving the
same ring gear in one axis).

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
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.
