Type Of Timken Imported Bearing Life

Timken imported bearings are precision mechanical basic parts. Due to the rapid development of scientific and technological progress, customers have higher and higher requirements for the quality of bearing products. It is important for the manufacturer to provide high-quality products that meet the standards and meet the service performance of the host, but it is more important to correctly use Timken imported bearings. In the technical work of special bearings for motorcycles in recent years, the author often encounters such problems, that is, the bearings are qualified after testing, but Timken imported bearings are stuck or have early stall failure after installation.

It mainly shows the sense of rotation stagnation, serious peeling of the working face, serious wear and even distortion and fracture of the cage. The analysis of failure results shows that there are not many quality problems belonging to the bearing itself, most of which are caused by improper installation and use. Therefore, the author believes that it is necessary to make some superficial summary on the common failure modes and mechanisms of Timken imported bearings, in order to play a role in attracting jade.

 

Life classification:

fatigue life, wear life, failure life and service life. Fatigue life: the cumulative time before the material of the main moving parts of Timken imported bearings reaches the limit and causes bearing failure.

Type Of Timken Imported Bearing Life

Rated dynamic load: the load that Timken imported bearing can bear when its service life is 10000 rpm. Equivalent dynamic load: it refers to the assumed load that the actual load of Timken imported bearing is converted according to the operating conditions for determining the dynamic load.

 

Wear life:

the accumulated working time before the clearance of Timken imported bearing increases to the specified limit due to normal wear. In terms of the industrial level of Timken imported bearings, the wear life should be > fatigue life, but in fact, the traction motor is just the opposite. Failure life: accumulated working time before Timken imported bearing fails and loses working capacity. Service life: it refers to the above three kinds of life. In theory, it refers to the fatigue life of Timken imported bearings. Under normal service conditions, it shows the wear life of Timken imported bearings. Under abnormal conditions and no manufacturing defects, it represents the fault life.
