Performance requirements for bearing bush

Bearing bush is one of the important parts of mechanical equipment, and its performance has a great influence on the stability and service life of the overall performance of the equipment. Dafeng Mingyue  will specify the performance requirements of an ideal bearing bush in this paper.

Firstly,the bearing bush should have high strength and hardness. The bearing bush should have high strength and hardness to bear large forces and torques, so as to ensure that the bearing bush will not break or deform under high speed and heavy load. At the same time, the bearing bush should have certain toughness and elasticity to withstand certain vibrations and impact during operation.

Secondly,the bearing bush should have strong wear resistance. In the process of use, the bearing housing carries the rotating parts of the equipment and is often worn. Therefore, it needs to have good wear resistance to withstand long-term work and frequent friction and wear, ensuring the life and stability of the equipment.

Thirdly, the bearing bush should have good thermal conductivity. The heat generated in the process of using the bearing bush needs to be dissipated in time, otherwise it is easy to cause thermal cracks or ablation of the bearing bush. Therefore, the material of the bearing shell must have excellent thermal conductivity, which can effectively dissipate heat and prevent overheating.

Fourth,the friction coefficient of the bearing bush should be very low. The bearing bush should have a low friction coefficient to reduce frictional resistance and energy loss.

Fifth,the bearing bush should have strong lubrication. The surface of the bearing bush needs to be coated with a smooth lubricating oil to reduce friction and wear between the bearing bush and other equipment parts. At the same time, lubricating oil also has the functions of cooling, noise reduction and shock absorption, which can ensure the normal operation of machinery and equipment.

Sixth,the bearing bush should be embeddable. The bearing material should have good adaptability and the ability to accommodate foreign objects, and can adapt to the shape changes of the journal and accommodate impurities entering the oil film, so as to reduce journal scratch and wear.

Finaly,the bearing bush should have certain anti-corrosion and anti-adhesion capabilities. Due to high temperature oxidation and certain additives in lubricating oil that can form organic acids, inorganic acids, and oxides, the bearing bush should have certain anti-corrosion capabilities; At the same time, the bearing bush should also have anti-adhesion capabilities to prevent the bonding between the bearing bush and the shaft neck.

Generally speaking, the performance requirements of bearing bush include strength, wear resistance, thermal conductivity and lubricity. This requires that the materials selected for bearing shell processing meet these requirements. The bearing materials should have high hardness, strength, low friction coefficient, strong fatigue resistance, good wear resistance, high temperature resistance and high pressure resistance, and the selection of materials should meet the use conditions, and have good processability and corrosion resistance.

Dafeng Mingyue strictly screens raw materials according to the above requirements to ensure that the required materials are from reputable and strong manufacturers, ensuring that the bearing shells we produce have the best performance, thus enabling long-term stable operation of mechanical equipment.
