High Precision Slew Drive Gearbox For High Holding Torque CSP Sun Tracking System
Small Size High Precision Slew Drive Gearbox For High Holding Torque CSP Sun Tracking System
Small Size High Precision Slew Drive Description
The advantages and disadvantages of tracking technology mainly depend on the quality of the control system and the drive system, and as the most commonly used driving equipment in the tracking system of the solar thermal power station, especially the tower CSP station, the slewing drive reducer can accurately and reliably drive the tracking system to track the sun in real time, and its rotation accuracy can directly affect the reflection accuracy of the mirror, and its reliability is related to whether the entire mirror field can operate normally. In addition, the slewing drive reducer also has important roles such as self-locking, wind resistance, anti-tilting, etc., which can be described as the "heart" that ensures the healthy operation of the tracking system.
