3 Inches Horizontal Slew Drive With Hardened Tooch For Sun Solar Tracker
Horizontal Slew Drive Description
Slew drives are perfect for applications that require both load holding and rotational torque from the same gear box. The drives come with an hourglass worm technology, which increase the efficiency of the drives. The difference between normal and hourglass technology is that, in a conventional worm gearing system, only one tooth of the gear is in contact with the worm shaft, whereas in hourglass, it has multi-tooth contact.
Advantages
The structure is compact, the return clearance is small, the precision is high, the service life is very long, and the rated output torque can be made very large. But the price is slightly more expensive. Planetary reducers are generally used when high torque is required in a limited space, ie small volume and large torque, and its reliability and life are better than spur gear reducers. Spur gear reducers are used for lower current consumption, low noise and high efficiency low cost applications. Planetary reducers are characterized by small size, high output torque and high transmission efficiency, as long as they have these requirements.

Applications
The use of rotary drive photovoltaic tracking system can be divided into two types according to the control method
(1) Passive control. Passive solar trackers typically rely on the forces of the environment to create a change in fluid density. This change provides an internal force that is used to make the components track the sun.
(2) Active control. Active solar trackers use externally provided power to drive circuits and actuators (motors, hydraulics, etc.) to make the components track the sun. Open-loop control is a tracking method that does not use a sensor that directly senses the position of the sun. It uses mathematical calculations of the sun's position (based on the time of day, date, location, etc.) to determine where the tracker should be oriented and drive the tracker's drivetrain accordingly.
