Abstract I believe that many people will encounter sliding bearings, when they are broken, then we will come today and talk about the causes of these damages.
I believe that many people will encounter sliding bearings, when they are broken, then we will come today and talk about the causes of these damages.
1. Some enterprises did not strictly follow the requirements of cleaning and anti-rust regulations and oil seal anti-rust packaging in the process of producing coating machine bearings to carry out anti-rust treatment on the coating machine bearing parts in the process and the assembled coating machine bearing products after assembly . For example, the turnaround time of the ferrule is too long, and the outer circle of the outer ring is in contact with corrosive liquid or gas.
2. The quality of the anti-rust lubricants, kerosene cleaning products used by some enterprises in production does not meet the requirements of process technology regulations.
3. The turning allowance and grinding allowance of sliding bearing rings of coating machines of some enterprises are too small, and the scale and decarburization layer on the outer circle are not completely removed.
4. The environmental conditions of some enterprises are poor, the content of harmful substances in the air is high, the turnover site is too small, and it is difficult to carry out effective anti-rust treatment. Coupled with the hot weather, production workers violated the anti-rust regulations and other phenomena.
5. Some enterprises' anti-rust paper, nylon paper (bag) and plastic tube and other coating machine sliding bearing packaging materials do not meet the requirements of the anti-rust packaging of the roller coating machine bearing oil seal is also one of the factors that cause rust.
6. As the price of the bearing steel of the coating machine drops, the material of the bearing steel of the coating machine gradually declines. For example, the content of non-metallic impurities in steel is relatively high (the increase of sulfur content in steel makes the material's own anti-corrosion performance decrease), and the metallurgical structure deviation. The bearing steel of the coating machine used by the production enterprises is more complicated, and the quality of the steel is even more mixed.
