3 Inch IP66 Small Slew Drive With 24VDC Planetary Gear Motor For Tilted Solar Tracking System
Small 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.www
