Contact Yield Initiation and Its Influence on Rolling Contact Fatigue of Case-Hardened Steels
(The American Society of Mechanical Engineers (ASME), 2020)Stress distributions and plastic deformation zones are factors directly influencing the fatigue life of components under cyclic contact. An effective approach to improving the resistance of a steel to contact fatigue failure ... -
Study of Oil Starvation in Journal Bearing Using Acoustic Emission and Vibration Measurement Techniques
(The American Society of Mechanical Engineers (ASME), 2020)This present article evaluates the state of starvation in a journal bearing using acoustic emission (AE) and vibration measurement techniques. A journal bearing requires a constant supply of oil in an adequate amount to ... -
Modeling of Crossed Roller Bearings Considering Roller Roundness Deformation
(The American Society of Mechanical Engineers (ASME), 2020)This paper presents a quasi-static five degrees-of-freedom model of crossed roller bearings that considers roller roundness deformation. The existing models of rolling element bearing do not account for ball and/or roller ... -
