Relationship Between Koyo Bearing Trajectory And Radial Load

Trajectory And Radial Load

When the Koyo bearing rotates, the raceway surfaces of the inner ring and outer ring of the Koyo bearing are in rolling contact with the rolling element, so the running track is a dark surface. The running track attached to the raceway surface is not abnormal, so the load conditions can be known. Therefore, when removing the Koyo bearing, please pay close attention to and observe the running track of the raceway surface.

Relationship Between Koyo Bearing Trajectory And Radial Load

If you carefully observe the running track, you will know that it only bears radial load, large axial load, moment load, or extreme uneven rigidity on the bearing housing. It can be checked Trajectory And Radial Load whether the unexpected load is added to the bearing and whether the installation error is Guoda, which will become a clue to investigate the cause of bearing damage.

Fracture Causes Of Imported Bearing Cage And Factors Affecting Bearing Performance

Fracture Causes Of Imported Bearing Cage And Factors Affecting Bearing Performance

Bearing plays an important role in social life.

Bearing is composed of cage, outer ring, rolling element and inner ring. Trajectory And Radial Load The components of bearing vary with different bearing types. What are the reasons for the fracture of imported bearing cage?

Creep is also one of the causes of cage fracture. The so-called creep mostly refers to the sliding Trajectory And Radial Load phenomenon of the ferrule. When the interference of the mating surface is insufficient, the load point moves to the surrounding direction due to sliding, resulting in the deviation of the ferrule from the axis or shell to the circumferential direction.

Once creep occurs, the mating surface will be significantly worn, and the wear powder may enter the Trajectory And Radial Load bearing to form a process of abnormal wear, raceway peeling, cage wear and additional load, which may even cause cage fracture.

Abnormal load of cage. If the installation is not in place, the inclination and the interference Trajectory And Radial Load amount are too large, it is easy to reduce the clearance, aggravate the friction and heat generation, soften the surface, and premature abnormal spalling.

With the expansion of spalling, the spalling foreign matter enters the Trajectory And Radial Load cage pocket, resulting in the operation block of the cage and additional load, which intensifies the wear of the cage. Such a deteriorated cyclic effect may cause the cage fracture.

Cage material defects and riveting defects may cause cage fracture.

The countermeasures are to strictly control in the manufacturing process. The invasion of foreign matters is a common mode of cage fracture Trajectory And Radial Load failure. Due to the intrusion of foreign hard foreign matters, the wear of cage and abnormal additional load may also lead to cage fracture.

Poor lubrication mainly refers to that the shaft is in poor oil state, which is easy to form adhesive wear and Trajectory And Radial Load deteriorate the working surface state. The tears caused by adhesive wear are easy to enter the cage, resulting in abnormal load on the cage, which may cause cage fracture.

Bearing plays an important role in the field of machinery. Bearing can not only be used in machinery, but also be made into some craft toys. Bearing Trajectory And Radial Load has had a great impact on our life.

What are the factors affecting bearing performance? The following is the analysis. The smelting quality and basic requirements of bearing steel the service life and reliability of rolling bearings are closely related to the smelting quality of bearing steel to a great extent. The smelting requirements of bearing steel are much stricter than those of general industrial steel.

High precision dimension requires steel for rolling bearings, which requires high dimensional accuracy, because most bearing parts have to be pressure formed. In order to save materials and improve labor productivity, most bearing rings are forged, steel balls are formed by cold heading or hot rolling, and small-size rollers are also formed by cold heading.

If the dimensional accuracy of steel is not high, the blanking size and weight can not be calculated accurately, the product quality of bearing parts can not be guaranteed, and it is easy to cause damage to equipment and molds.

Especially strict requirements for carbide non-uniformity. In bearing steel, if there is serious uneven carbide distribution, it is easy to cause non-uniformity of microstructure and hardness in the process of heat treatment. The structural non-uniformity of steel has a great impact on the contact fatigue strength.

In addition, the serious non-uniformity of carbide is also easy to cause cracks in the bearing parts during quenching and cooling, and the non-uniformity of carbide will also reduce the service life of the bearing. Therefore, in the bearing material standard, there are clear special requirements for steels of different specifications.
