IP66 Single Axis Rotatory Slewing Drive WIth High Presicion For PV Trackers
Single Axis Rotatory Slewing Drive Description
Rotary slewing drive products can be divided into two types: open type and closed type according to the closed state, and can be divided into gear type and worm gear type according to the different transmission forms. Hangtuo has these types of products, and users need to meet their own application requirements and Use the environment to make choices.
Usually, the closed structure is used in humid, medium dust or corrosive gas environments, and in those occasions with high environmental protection requirements that do not allow the leakage of lubricating grease. The closed environment can effectively prevent impurities from entering the rotary drive body and improve the machine. However, when there is too much dust in the environment and the rotary drive is completely placed in the dust, the seals that play a sealing role will accelerate wear and fail quickly. At this time, the closed environment may be inconvenient for maintenance and parts replacement. It is more appropriate to use an open structure, and to choose tooth surface hardening to improve the durability of the machine. In addition, the open structure is easy to clean up impurities. If the use and maintenance can be done well, it may not necessarily have a shorter life than the closed structure. In the process of product selection, various factors must be considered comprehensively.

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.
