Description

Technical Field

[0001] The utility model relates to the technical field of bearing bushes, in particular to an automatic cleaning machine for engine bearing bushes. Background Art

[0002] The bearing of the engine is the contact part between the sliding bearing and the shaft. It is very smooth and is generally made of wear-resistant materials such as bronze and anti-friction alloy. In special cases, it can be made of wood, plastic or rubber. It is also called "shaft liner" and has a tile-shaped semi-cylindrical surface. The bearing material is usually softer and the inner cylindrical surface is not suitable for grinding. It can be processed by boring, diamond boring, scraping or grinding. When grinding, the method of matching the shaft diameter should not be used, but a special grinding rod with the same size as the bearing hole should be used. When the sliding bearing is working, a very thin oil film is required between the bearing and the rotating shaft for lubrication. If the lubrication is poor, there will be direct friction between the bearing and the rotating shaft, and the friction will generate very high temperature. Although the bearing is made of special resistant Although the bearing is made of high-temperature alloy materials, the high temperature generated by direct friction is still enough to burn it out; the bearing may also burn out due to factors such as excessive load, high temperature, impurities in the lubricating oil or abnormal viscosity. After burning, the sliding bearing is damaged, and after the bearing has been used for a period of time, there will be some impurities on the surface. At this time, the bearing needs to be cleaned to achieve the original matching accuracy; but the common cleaning method is manual cleaning, but the efficiency of manual cleaning is extremely low, and after cleaning, the manual wiping process of the bearing is also prone to unclean wiping, which cannot meet the cleaning standards, and the bearing is naturally dried after cleaning, which greatly reduces the drying efficiency of the bearing shaft, resulting in the subsequent processing efficiency being constrained.
