Hourglass Worm Gear Slewing Ring Bearing For Curved Mirrors Parabolic Csp
Worm Gear Slewing Ring Bearing Description
The slewing drive is a perfect motion control product for the application which requires rotational torque strength, low speed and good accuracy.
Slew drive for solar: it is designed in solar photovoltaic panel rotation and improves power generation efficiency. Concentrated solar powers include solar concentrator solar dish, CPV (Concentrated Photovoltaics), CSP (Concentrated solar power), solar parabolic trough, PV tracker(single axis & dual axis solar tracking solutions). For wind generators: Slewing drives are used to rotate the pedestal in wind turbines. For Construction Machinery Application: widely applied on mounted truck crane, aerial working platform, cranes, timber grab. For Industry Market: Automation and CNC assembly line, robotic arm. For Satellite: space communications and global positioning systems in satellite dish.

Applicaiton in Parabolic CSP
Slewing drives are a perfect rotating part for CSP parabolic trough. A parabolic trough applies sun-tracking curved mirrors (called parabolic troughs) to maximize the sun’s energy and consequently the efficiency of heat production. The sun's rays are captured and reflected onto a receiver pipe filled with a heat transfer fluid (water or thermal oil) that is located in the central point of the troughs.
