Embodiment 1
[0057] A dynamic lubricated roller bearing structure applied to wind power generators, including: a bearing inner ring 10 , a bearing outer ring 20 , bearing rollers 30 , a disk cover 40 , and a dynamic oil replenishing mechanism 50 . The bearing inner ring 10 is connected with the main shaft 90 of the wind power generator.
[0058] An oil inlet hole 11 is provided on the bearing inner ring 10 side. The bearing outer ring 20 is sleeved on the bearing inner ring 10, and an inner cavity 12 is formed between the bearing outer ring 20 and the bearing inner ring 10 at the middle end, and the inner cavity 12 communicates with the oil inlet hole 11, and the bearing outer ring 20 surrounds the bearing The inner ring 10 and the bearing inner ring 10 have a rotation function relative to the bearing outer ring 20 . Bearing rollers 30 (cylindrical or conical) are arranged between the bearing inner ring 10 and the bearing outer ring 20 to form a rolling arrangement.
[0059] The disk cov...
Embodiment 2
[0071] A dynamic lubricated roller bearing structure has the same characteristic structure as that of Embodiment 1, wherein, such as Figure 7 As shown, the inner surface of the bearing outer ring 20 is provided with a transmission mechanism 70 with a rotating function, the transmission mechanism 70 is in close contact with the bearing roller 30 , and the side end of the transmission mechanism 70 is provided with a cam 71 .
[0072] The inner surface of the bearing outer ring 20 is also provided with a concave notch, the notch has a movable housing 81 slidingly arranged, the movable housing 81 is connected with a pressure spring 82, and the movable housing 81 faces one end of the inner cavity 12 Has an elastic membrane 83 .
[0073] Such as Figure 8 As shown, when the bearing works for a long time and consumes grease, resulting in insufficient grease on the contact surface between the bearing roller 30 and the bearing outer ring 20, the bearing roller 30 pushes the transmiss...
Embodiment 3
[0075] A dynamic lubrication method, which includes the following steps:
[0076] Grease is injected into the inner cavity 12 through the oil inlet hole 11 on the inner ring 10 side of the bearing, and then as the grease in the inner cavity 12 increases, it is guided to the outer cavity 41 through the inner cavity 12, and the excess grease is released from the outer cavity 41 side. The oil discharge hole 13 is effectively discharged;
[0077] The grease discharged from the oil discharge hole 13 is collected through the circulation oil passage 51 of the dynamic oil supply mechanism 50, so that the grease enters the oil storage chamber 54 of the oil supply cylinder 52 through the circulation oil passage 51;
[0078]When the bearing is working, through the action of the bumps provided at the sliding connection between the bearing inner ring 10 and the dynamic oil supply mechanism 50, each time the bearing inner ring 10 rotates one revolution, the stress block 56 is triggered to m...
