14 Inches IP66 High Moment Torque Electric Slew Gear Reducer For Solar Power System
Electric Slew Gear Reducer Description
Electric Drive Slewing Drive Tracker: An electric drive system converts electrical energy into rotational motion in an AC motor, a brushed DC motor, or a brushless DC motor. The motor is geared down with a gearbox to achieve high torque. The final stage of the gearbox transmits linear or rotational motion to push the tracker's axis of rotation.

Slewing Drive DC Motors
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.
Applications
Single-axis tracking system: The solar photovoltaic power generation system using the slewing drive device has the characteristics of low cost, stable performance, reasonable structure, accurate tracking, and easy to use. There is no need to calculate the sun's position data in various places, and it is not limited by geographical and external conditions, ensuring that the system is facing the sun and accurately tracking the sun anytime, anywhere. It can be used normally in the temperature range of -20°C to 120°C. The tracking accuracy can reach 0.1°. Maximize the accuracy of sun tracking and maximize the utilization of solar energy.
