Through the device, lubricating rotation is realized between the cylinder cross shaft and the bearing, and the problem of meniscus wear caused by the rigid rotation without lubrication between the original structure composite bearing and the meniscus is solved, and the problem of abnormal vibration of the pitch oil red caused by severe wear of the meniscus and the cross shaft is solved, and the damage of the meniscus, the composite bearing, the cross shaft and the pitch cylinder is reduced, and the operation stability of the wind turbine is improved. However, when the device is in use, once the meniscus channel of the meniscus is misaligned with the bearing channel of the bearing, it is impossible to realize the lubrication of the cylinder cross shaft and the bearing, and the problem of meniscus wear cannot be solved. Therefore, a wind power meniscus wear-resistant structure is proposed to address the above problems. Utility Model Content

[0006] A bearing channel is provided on the outer side of the bearing, a meniscus channel is provided inside the meniscus, and a docking assembly is provided inside the meniscus channel;

[0007] The docking assembly includes a sliding cylinder and a limiting plate. A sliding groove is provided on the outer side of the sliding cylinder, and a limiting plate is provided inside the sliding groove. One end of the limiting plate is fixedly connected to the meniscus.

[0008] When the prior art is in use, once the meniscus channel of the meniscus is misaligned with the bearing channel of the bearing, it is impossible to lubricate the oil cylinder shaft and the bearing, and the meniscus wear problem cannot be solved. However, the device inserts one end of the sliding cylinder into the interior of the bearing, and the meniscus channel and the bearing channel can be precisely docked. At this time, the lubricating oil can be ensured to enter the specified position smoothly, achieve the lubrication purpose, ensure the quality of the meniscus, and have strong wear resistance. The setting of the limit plate can ensure that the sliding cylinder slides to a certain extent.

[0009] As an optional solution of the wind power meniscus wear-resistant structure described in the utility model, a sealing ring is fixedly connected to the outer side of the sliding cylinder.

[0010] As an optional solution of the wind power meniscus wear-resistant structure described in the utility model, the lower outer diameter of the sliding cylinder is 0.7 times the upper outer diameter of the sliding cylinder, and the bottom of the sliding cylinder is inserted into the bearing channel.

[0011] When the lubricating oil circulates, the sealing ring on the outside of the sliding cylinder can play a sealing role to prevent the leakage of the lubricating oil. At the same time, one end of the sliding cylinder is set with a narrow mouth, which can be connected with the bearing channel to ensure that the lubricating oil flows smoothly into the bearing, thereby lubricating the cylinder shaft, bearing and meniscus, and ensuring that the device has strong wear resistance.

[0012] As an optional solution of the wind power meniscus wear-resistant structure described in the utility model, wherein: a fixing ring is fixedly connected to the inside of the sliding cylinder, and a guide bucket is fixedly connected to the bottom of the fixing ring.

[0013] As an optional solution of the wind power meniscus wear-resistant structure described in the utility model, the guide bucket is made of rubber.

[0014] When the lubricating oil is circulating, it can flow smoothly through the fixed ring and the guide bucket to achieve lubrication. When disassembling, air is pumped in the opposite direction through the external pump body. At this time, the guide bucket collapses, which can ensure that the sliding cylinder slides to the outside of the meniscus channel inside the meniscus. At this time, the sliding cylinder is separated from the bearing, ensuring that the device can be separated normally.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] When the utility model is in use, one end of the sliding cylinder inside the meniscus channel opened inside the meniscus is inserted into the bearing channel inside the bearing, and accurate docking can be achieved at this time, ensuring that the lubricating oil can smoothly pass through the sliding cylinder into the bearing channel, achieving lubrication of the oil cylinder ten-shaft, the bearing and the meniscus, and ensuring that the device has strong wear resistance;

[0017] When the device is used to disassemble the meniscus and the bearing, the air is pumped in the opposite direction through the external pump body, and the guide bucket collapses, so that the sliding cylinder can slide to the outside of the meniscus channel inside the meniscus. At this time, the sliding cylinder is separated from the bearing, and the device can be separated normally.

[0018] A sliding groove is provided on the outside of the sliding cylinder, and a limit plate is arranged. At this time, the limit plate can limit the sliding cylinder, and the sealing ring can seal it. BRIEF DESCRIPTION OF THE DRAWINGS
