Description

Technical Field

[0001] The utility model relates to the technical field of oil-free bushings, in particular to a flange-type oil-free bushing fixing assembly. Background Art

[0002] Flange oil-free bushings are self-lubricating bearings made from a high-strength copper alloy. Holes are machined into the working surface and filled with solid lubricant in a specific proportion based on operating conditions. The high-strength copper alloy provides a high load-bearing capacity, while the solid lubricant creates a low-friction pair. Under dry friction conditions, a pre-lubricating film applied to the bearing surface ensures that the solid lubricant is transferred to the mating element in the shortest possible time, forming an effective solid lubricating film. Oil-free bushings are used in conjunction with shaft components for both rotational and linear motion, making them a common component in modern industrial equipment.

[0003] There is sliding friction between the oil-free bushing and the shaft. After a period of use, it needs to be replaced due to wear. When replacing, it needs to be fixed to push the bushing out. However, the fixing assembly of the existing technology has a poor fixing effect, which makes it easy to fall off when fixed. At the same time, the replacement time is long. Therefore, there is an urgent need for a flange-type oil-free bushing fixing assembly to overcome the above defects.

[0004] The purpose of the utility model is to provide a flange-type oil-free bushing fixing assembly, which has the advantages of good fixing effect and convenient replacement, so as to solve the problems raised in the above-mentioned background technology. Utility Model Content
