1. The cylindrical roller for the bearing that can be quickly repaired and replaced is set on the outer side of the connecting shaft by setting the connecting shaft, the storage groove, the first oil discharge port and the baffle, and then the two baffles are used to oppose the roller. When the roller body rotates outside the connecting shaft, the two baffles will limit the position of the roller body. During this process, the lubricating fluid inside the storage tank will be discharged through the first oil discharge port, and the The connecting shaft is lubricated. At the same time, the lubricating liquid will also be sent to the feed port through the second oil discharge port, and finally discharged into the guide hole inside the connecting shaft, which facilitates the cylindrical roller to provide itself with lubricating liquid and avoids this The increased vibration of the cylindrical roller due to the adsorption of dust not only reduces the noise, but also reduces the wear of the cylindrical roller, thereby ensuring the service life of the cylindrical roller.

2. The cylindrical roller for the bearing that can be quickly repaired and replaced is fixed above the external cage through the fixing block by setting the sealing plate, the fixing block and the oil injection hole, and the fixing block can pass the lubricating fluid through the guide hole. At the same time, the lubricating liquid can also be injected into the storage groove through the oil injection hole, and finally the oil injection hole is sealed by the sealing plate, which facilitates the rapid installation of the cylindrical roller, thereby improving the flexibility of the cylindrical roller. At the same time, It is more convenient to fill the cylindrical roller with lubricating fluid, thereby improving the applicability of the cylindrical roller.

Detailed ways

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

As shown in Figures 1-3, the utility model provides a technical solution: a cylindrical roller for bearings that can be quickly repaired and replaced, including a connecting shaft 1, a roller body 2 is provided on the outer sleeve of the connecting shaft 1, and the connecting shaft 1 Both sides are fixedly connected with fixed blocks 8, and the fixed blocks 8 are in the shape of a cube. By setting the fixed blocks 8, it is convenient to quickly install the cylindrical roller, thereby improving the flexibility of the cylindrical roller;

The fixed block 8 communicates with the connecting shaft 1 through the guide hole 7. The shape of the connecting shaft 1 matches the shape of the roller body 2. By setting the guide hole 7, it is convenient to connect the fixed block 8 and the external cage. Lubricating fluid is provided so that the cylindrical roller can be quickly disassembled. The roller body 2 is provided with a storage groove 3, and the roller body 2 is provided with an oil injection hole 9. The roller body 2 is clamped with a sealing plate 10 through the oil injection hole 9. By setting the sealing plate 10, it is more convenient to fill the cylindrical roller with lubricating fluid, thereby improving the applicability of the cylindrical roller;
