Problems solved by technology

[0002] Wind turbines mostly use lubricating grease for bearing lubrication. Grease lubrication has high requirements for oil circuit structure design. Poor oil circuit structure design will cause various adverse consequences: 1. Too fast oil rejection leads to lack of lubricating grease, so the bearing temperature rises If it is too high, it will damage the bearing; 2. Poor oil drainage will cause the lubricating grease to occupy most of the bearing space, and the heat dissipation will be relatively poor, causing the bearing temperature to rise too high, and the base oil of the grease will be oxidized. As time goes by, the base oil will gradually Loss, leakage, grease dries out, hardens, bearings lose lubrication, leading to damage
Therefore, it is necessary to design a reasonable lubricating structure so that the pumping pressure is too high to cause lack of grease, or the pumping pressure is too low to cause poor discharge of waste oil

Abstract

The invention discloses a wind driven generator bearing lubricating structure which comprises a left baffle (1), a main body (2) and a right baffle (3), wherein the main body (2) is internally provided with a bearing A (4), a left oil retainer (5), an oil slinger (6), a right oil retainer (7) and a bearing B (19); the left baffle (1) is provided with an oil inlet A (10) and an oil inlet B (11), the oil inlet B (11) is communicated with a cavity A (12), an oil inlet channel (14) is communicated with the oil inlet (10) and a cavity B (13), the bottom of the left oil retainer (5) is provided with a notch (16) communicated with the internal space of a right groove, and an oil discharge channel (18) communicates the notch (16) with an oil discharge hole (17). The wind driven generator bearing lubricating structure has the beneficial effects that two bearings are lubricated simultaneously, so that each bearing is lubricated by new grease; a reasonable oil shedding structure is designed, and waste oil is discharged from the same oil discharge hole; the oil retainer and the oil slinger enable an oil chamber to store proper quantity of grease.
