Vertical Worm Gear Single Axis Small Slew Drive , Solar Slew Drive With 0.1 Degree Accuracy
Vertical Slew Drive Description
Solar tracker must have smooth, slow and sturdy motion. The tracker should possess high position accuracy and high degree of reliability. These requirements can be attained by specially designed drivers known as slewing drivers.
Accuracy: 0.1 Degree
Available: 3 inch - 12 inch
Horizontal installation
It is advised to mount the slewing drives upside down on the azimuth axis in solar applications for better protection and add protection for the elevation axis. For other applications, the mounting directions shall be based on the evaluation of the protection level and it shall be better for better protection.
Vertical installation
It is advised to mount the slewing drives referring to attached drawing upside in solar applications for better protection. For other applications, the mounting directions shall be based on the evaluation of the protection level and it shall be better for better protection.

Features
1. By adopting slewing bearing as its core component, slewing drive can bear axial force, radial force and tilting moment simultaneously.
2. Slewing drive is widely applied in modular trailers, all types of cranes, aerial working platform, solar tracking systems and wind power systems.
3. Electric and planetary gearboxes can be designed according to customer's requirement.
4. Slewing drive has the advantage of saving space in facilities, max load capacity in a compact design, extensive lifespan, reduced maintenance costs, etc.
