Vertical Single Axis Slew Drive With For Small Backlash Solar
Tracking Systems
Vertical Single Axis Slew Drive Description
Due to the use of slewing bearing and annular worm structure, the
solar tracking rotary drive device can achieve multi-tooth contact,
has the characteristics of large transmission torque and stable
operation; it can withstand large radial and axial loads and strong
overturning. Torque (anti-wind resistance) is being widely used in
solar photovoltaic power generation tracking systems and other new
energy industries by domestic and foreign customers. The products
currently have 9 models ranging from 3 inches in diameter to 25
inches in diameter, and more than 60 varieties, which can meet the
needs of different forms of photovoltaic, photoelectric,
photothermal ordinary and precision tracking.
