Problems solved by technology
The sun gear is located above the oil level, which poses a huge challenge to the lubrication of the sun gear and planetary gear meshing
In particular, the tooth width of the high-power model gear is wider than that of the low-power model. Although the meshing lubrication here is forced lubrication, the lubricating oil cannot be sprayed to the meshing area effectively and evenly. Although this lubrication method has some Lubrication effect, but can not get good lubrication

The invention discloses a planetary gear train oil spray lubrication structure of a wind power gear box. The planetary gear train oil spray lubrication structure of the wind power gear box comprises aplanet gear, a sun gear and a planet carrier, wherein the planet gear is rotatably connected to the planet carrier and meshes with the sun gear. The planetary gear train oil spray lubrication structure of the wind power gear box is characterized in that the planet carrier is provided with an oil spray structure for spraying oil to the meshing position of the planet gear and the sun gear and a lubricating oil circuit for supplying oil to the oil spray structure; and the oil spray structure communicates to the lubricating oil circuit. The planetary gear train oil spray lubrication structure ofthe wind power gear box can be used for efficiently and uniformly lubricating a planetary gear train.
Description
technical field [0001] The invention relates to an oil injection lubrication structure of a planetary gear train of a wind power gearbox. Background technique [0002] The gearbox is a key component of the wind turbine. In the wind generator, the gearbox generally adopts a multi-stage planetary gear train. In the planetary gear train, due to the heavy load on the planetary gear and the sun gear in the gearbox, sufficient lubrication must be ensured during work. And in order to ensure the transmission efficiency of the gearbox and reduce the risk of oil leakage, the oil level of the gearbox should not be too high. The sun gear is located above the oil level, which poses a huge challenge to the lubrication of the sun gear and the planetary gear mesh. In particular, the tooth width of the high-power model gear is wider than that of the low-power model. Although the meshing lubrication here is forced lubrication, the lubricating oil cannot be sprayed to the meshing area effect...
