Bearing endurance and reliability-a user's perspective

摘要

Rolling-element bearings are an integral part of mechanical systems from home washing machines to space stations and rockets that put them in orbits.Bearing reliability and endurance are critical for operational success of mechanical systems.A trend in modern industrial machinery such as gearboxes is to increase the power density without changing the basic equipment dimensions.For such cases,often the stated ￡]0 bearing lives are not achieved.
