Non-standard bearing manufacturing maintenance and the requirement of smelting

Non-standard bearing manufacturing maintenance and the requirement of smelting source: bearing | last updated: - 2020 09 - 14 non-standard bearing manufacturing maintenance for non-standard bearings and keep its long-term performance into full play, must earnestly to do regular maintenance ( Regular inspection) 。 Through proper periodic inspection, do early detection of fault, prevent accident arrangement is very important to increase productivity and efficiency. Non-standard bearings cleaning non-standard bearings will be removed when checking, use methods such as photography first appearance record. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing. A, non-standard bearings cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame. B, rough washing, oil using a brush to remove grease or adhesive. If at this time in oil bearing, pay attention to the rolling surface due to foreign bodies such as damage. C, fine cleaning, slowly rotating bearings in the oil, must be carefully. Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. After cleaning, coating anticorrosive oil or antirust grease on the bearing immediately. Non-standard bearing steel smelting requirements for non-standard bearing steel, surface defects, including cracks, slag inclusion, burr, scarring, scale, etc. , internal defects including shrinkage cavity, bubbles, white spots, such as severe osteoporosis and segregation. These defects for the processing of non-standard bearing, non-standard bearing performance and life has a great influence, explicitly stipulated in the non-standard bearing material standard is not allowed. These defects. Carbide inhomogeneity requirements in non-standard bearing steel, if there is a serious uneven distribution of carbide, are in the process of heat treatment process is easy to cause tissue and uneven hardness, the organization of the steel inhomogeneity has a larger effect on contact fatigue strength. In addition, the serious carbide inhomogeneity is easy to make non-standard bearing parts during quenching cracks, carbide inhomogeneity will results in the decrease of non-standard bearing life, therefore, in the material standard, non-standard bearing of different specifications of the steel have clear special requirements.
