VE7 Single Axis Worm Gear Slewing Bearings With Nema23 For Solar Tracking Systems
Worm Gear Slewing Bearings Description
Fresnel concentrated solar power station is a kind of CSP solar tracking system. The working principle is similar to trough type photothermal power generation, except that the Fresnel structure condenser is used instead of the mirror. This makes it relatively inexpensive, but the efficiency is correspondingly reduced.
Because such a system has only a few times of concentrating, the quality of the heated water vapor is not high, so that the annual power generation efficiency of the whole system can only reach about 10%; but due to the simple structure of the system and the direct use of heat-transfering medium to generate steam, its construction and maintenance costs are also relatively low.
Enveloping Worm Gear Slew Drive Features
1. Rotate 360°
2. Connect a driving motor on the left or right side
3. Grease had been filled before factory
4. Simple installation and rational space utilization
5. Self locking worm gear
6. Easy and fluent method of starting and stopping
7. High backholding torque, suitable for vertical installation
8. Low maintenance

Applications
Parabolic Collector Concentrating Solar Power Plant
Adopts north-south horizontal axis design, effectively improve the collector heat gains. Ultralimit mechanical structure design, collector can achieve wind speed ≤ 7m/s, tracking precision is 0.1°; Gust wind speed in any state ≤ 20m/s, collector is not damaged. Stop protecting state, down wind speed ≤ 32m/s, collector is not damaged.
