Technical Field

[0001] This utility model relates to the field of ultra-thin large radial track bearing technology, specifically a self-lubricating ultra-thin large radial track bearing. Background Technology

[0002] On high-speed wire rod production lines in steel companies, rolling mills roll steel billets at 100 meters per second at 800 degrees Celsius to produce finished products. Such productivity requires bearings to rotate tens of thousands of times per minute. The 800-degree Celsius temperature of the steel billet material itself puts the bearings in a very high ambient temperature. Currently, most rolling mill bearings used are steel bearings. Under such high-speed and high-temperature conditions, their wear rate accelerates dramatically, and the bearings will fail quickly. Premature bearing failure will lead to the shutdown of the entire equipment, reducing production efficiency and increasing production costs.

[0003] A self-lubricating rolling bearing, CN201320318532.0, can effectively improve bearing failure caused by high temperature and high speed wear by adding a self-lubricating sliding layer, and greatly improve the service life of the bearing. However, it has shortcomings: the lubrication effect of existing equipment is not good, the disassembly and assembly effect is not good, the oil injection effect is not good, and it is inconvenient to use. Therefore, a self-lubricating ultra-thin large radial rail bearing is needed to solve the above problems. Utility Model Content

A fixing pipe is inserted into the inner wall of the oil inlet, and a one-way valve is fixedly connected to one end of the fixing pipe. A connecting groove is provided in the middle of the inner wall of the ball support ring.

[0006] Preferably, the sealing cover is installed in a positioning splicing manner with the positioning slot, the positioning insert, and the ball support ring, and the positioning insert is bolted to the positioning slot by fixing bolts.

[0007] Preferably, the ball bearings are slidably connected to the outer ring and inner ring via a ball bearing support ring, and the ball bearing support ring is circulatedly connected to the ball bearings via a connecting groove. The ball bearing support ring and the limiting support block are sealed and connected to the ball bearings via a guide groove.

[0008] Preferably, the ball is installed in a sealed rolling support manner with the outer ring body and the inner ring body through a limiting support block, and the shape of the inner side of the limiting support block matches the shape of the outer wall of the ball.

[0009] Preferably, the oil inlet is connected to the guide groove in one direction via a one-way valve, and the oil inlet and the one-way valve are symmetrically distributed on both sides of the sealing cover.

[0010] Preferably, the one-way valve is installed in a screw-on seal with the oil inlet via a fixed pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This self-lubricating ultra-thin large radial track bearing can seal and support the balls through the limiting support block, and can also circulate and guide the oil through the guide groove and the connecting groove, so as to quickly circulate and guide the oil, avoid leakage, and improve the lubrication effect. Moreover, the sealing cover can be quickly positioned and disassembled by the fixing bolts, positioning slots, and positioning blocks, which facilitates the quick disassembly and assembly of the balls and ball support rings for easy replacement.
