Gear box lubricating device for wind driven generator
2010
The utility model relates to a gear box lubricating device for a wind driven generator, which comprises a main lubricating system and a bypass filtration system, wherein the main lubricating system is connected with a gear box of the wind driven generator to form a lubricating loop; the main lubricating system comprises a main loop filtration system for coarse filtration and a motor pump system connected with the main loop filtration system; and the bypass filtration system is connected with the gear box and is used for fine filtration. The gear box lubricating device for the wind driven generator has simple structure, can be conveniently disassembled to carry out replacement and maintenance of a filter element and obtains more stable and reliable gear box lubricating effect by arranging a device for detecting the temperature and the pressure of lubricating oil. In the extra-low temperature environment, the gear box lubricating device for the wind driven generator makes the oil temperature raise by a bypass heating system, and the oil which is subjected to coarse filtration and fine filtration by the main loop filtration system can lubricate the gear box; and after the oil temperature raises, the lubricating oil is subjected to secondary filtration of the main loop filtration system and the bypass filtration system sequentially so as to provide the high-quality lubricating oil for the gear box and prolong the service life of the gear box.
