Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a separate wind power generation gear box. Background Art

[0002] Wind power generation converts the kinetic energy of wind into electrical energy. Usually, the speed of the wind wheel is very low, far from the speed required by the generator to generate electricity. It must be achieved through the speed-increasing effect of the gear pair of the gearbox, so the gearbox is also called a speed increaser. The gearbox is filled with lubricating oil to prevent friction, lubricate gears, and dissipate heat and cool, thereby extending the life of the gears. However, after long-term use, the lubricating oil will contain gear meshing wear particles, lubricating oil aging decomposition sediments and other pollutants. Generally, a filtering device is provided to filter out the sediment in the filtered lubricating oil.

[0003] However, the existing wind power generation gear box has many gears installed inside the box, and the gear meshing is relied on to drive the flow of lubricating oil. After a long period of accumulation, oil stains will be deposited on the filter device, which needs to be inspected and repaired frequently. The cleaning work relies on manual labor, and it is difficult to fully remove the sediment and other pollutants in the lubricating oil. In addition, some areas cannot be fully lubricated. The lubricating oil falls from the gears and flows into the gear box. The lubricating oil at the bottom cannot be effectively used, resulting in unsatisfactory lubrication effect, reducing the service life of the gears, affecting the working power generation efficiency, and increasing the cost of use. Therefore, a separate wind power generation gear box is proposed. Utility Model Content
