Problems solved by technology
[0006] The purpose of the present invention is to solve the poor lubricating effect of the regular immersion into the oil tank in the gear box casing currently used for planetary-grade rolling bearings, and use an oil delivery pump to implement ring lubrication on the lubrication points by means of pipelines, nozzles and throttling orifice plates. The way of spraying is difficult to get close to the planetary wheel bearings, especially when it is difficult to process the annular oil groove in the lubricating oil circuit set in the pin shaft of the planetary wheel, etc., a new lubricating mechanism in the wind turbine gearbox is provided

Embodiment Construction
[0016] The accompanying drawings disclose the specific structures of the embodiments of the present invention without limitation, and the present invention will be further described below with reference to the accompanying drawings.
[0017] Depend on figure 1 It can be seen that the shape of the pin shaft cover 4 is a stuffy cover, and the outer edge of the pin shaft cover 4 is provided with an annular oil groove 21. After installation, the pin shaft cover 4 and the end of the pin shaft form an oil pool 26, and the lubrication of the oil pool 26 The oil inlet 25 is provided at the bottom of the annular oil groove 21 .
[0018] Depend on figure 2 It can be seen that the oil injection ring 14 includes a vertical oil passage 18 and a horizontal oil passage 15. The inlet end of the oil injection ring 14 is an annular oil groove 23. The lubricating oil passage 17 in the box communicates with the annular oil groove 23 at the inlet end of the oil injection ring 14. There is at le...

The invention relates to lubrication mechanism in wind power generator gear case, oil outlet of oil transfer pump is communicated with entry end of the case body lubrication oil circuit, an oil spout ring is provided between the case body and the lubrication oil circuit of planet carrier flange, the oil spout ring enters into the lubrication oil circuit of planet carrier flange via ring shaped oil groove of slider entry end, the lubrication oil circuit of planet carrier flange is communicated with lubrication oil circuit of the planet carrier pin roll, and terminal of the lubrication oil circuit of the planet carrier pin roll is a planet wheel bearing, one terminal of the planet carrier pin roll is provided with a pin roll gland, and the lubrication oil circuit of the planet carrier flange is communicated with the lubrication oil circuit of the planet carrier pin roll through a pin roll gland. The advantages are: reliable lubrication because of using implementation of the forced lubrication; if stop supply oil for a short time, the oil lubrication stored in oil sump can still provide lubrication for planet wheel bearings because a pin roll gland is disposed in pin roll end; furthermore, machining is convenient by providing ring shaped oil grooves to the pin roll gland, the oil spout ring and the slider block.
Description
technical field [0001] The invention relates to a lubricating mechanism, in particular to a lubricating mechanism in a wind turbine gearbox. Background technique [0002] As we all know, planetary gears and planetary-cylindrical gears are often used in the gearbox of wind power equipment. How to lubricate and cool the planetary rolling bearing directly affects the service life of the gearbox. [0003] At present, a common method is to make them periodically immersed in the oil sump located in the gearbox casing during the working process. This lubrication and cooling method is closely related to the structure of the bearing, the inclined position of the longitudinal axis of the transmission gearbox, the rotational speed of the planet carrier, the residence time of the bearing in the oil sump and the viscosity of the lubricating oil, etc.; The maximum oil level is limited by the labyrinth seal on the rotor side and cannot be too high, resulting in a limited immersion depth o...
