Thin wall embedded self-lubricating bearing and manufacturing method thereof

Abstract

The invention discloses a thin wall embedded self-lubricating bearing, comprising a plate, wherein the working face of the plate is uniformly distributed with blind holes, and the blind holes are internally provided with a solid lubricant. The manufacturing method of the bearing is as follows: blind holes are machined on copper alloy sheets; then the solid lubricant is pressed in the blind holes in interference fit tightly; the plate surface embedded with the solid lubricant is polished smoothly; lastly the thin wall embedded self-lubricating bearing is obtained after the sheets are sheared and rolled forming. The bearing manufactured according to the method has the advantages of thin wall, small volume and light weight, thereby simplifying the production technology, reducing the cost, and improving the production efficiency.

Description

technical field [0001] The invention relates to a self-lubricating bearing and a manufacturing method, in particular to a thin-wall inlaid self-lubricating bearing with simple production process and low cost and a manufacturing method. Background technique [0002] The existing thin-wall embedded self-lubricating bearings have the advantages of thin wall, small size and light weight, but due to the need to use more non-ferrous metals, the product cost is high, and sintering and other processes are required in the manufacturing process, and the production process is complicated , the production cost is higher. For example, the Chinese patent number is ZL00237465.X, a utility model patent named "thin-walled copper-based inlaid composite self-lubricating bearing", the disclosed technical solution is "Using a copper plate of 1.0-5.0mm, and uniformly Blind holes are distributed, and tin bronze powder or dendritic copper powder of 40-150 meshes are spread in the blind holes, and ...

[0002] The existing thin-wall embedded self-lubricating bearings have the advantages of thin wall, small size and light weight, but due to the need to use more non-ferrous metals, the product cost is high, and sintering and other processes are required in the manufacturing process, and the production process is complicated , higher production cost

For example, the Chinese patent number is ZL00237465.X, a utility model patent named "thin-walled copper-based inlaid composite self-lubricating bearing", the disclosed technical solution is "Using a copper plate of 1.0-5.0mm, and uniformly Blind holes are distributed, and tin bronze powder or dendritic copper powder of 40-150 meshes are spread in the blind holes, and then lubricants are inlaid. During the manufacturing process, a series of sintering processes are required to make the copper powder in the blind holes form certain pores. , so that the solid lubricant is firmly combined with the copper powder through the pores, the manufacturing process is complicated, the production cost is high, and the production efficiency is low
