Fatigue Failure and Ball Bearing Friction
Tribology Transactions, 2000According to the standard method for calculation of life ratings for rolling contact bearings, failure is considered to occur at the initiation of the first spall in a rolling component surface. While this is acceptable for most bearing applications, in many applications bearing operation may effectively continue for a period of time during which ...

ANALYSIS OF ROLLING BEARING FAILURES
Mechanics and TechnologiesДанные о доле различных видов повреждений подшипников качения у тракторов различных марок и даже у тракторов одной марки, но в различных выборках, могут несколько отличаться, так как это соотношение является результатом влияния ряда переменных факторов, в том числе нагруженности подшипниковых узлов, свойств абразивных частиц, попадающих в смазку и ...

Bearing Friction and Failure Mechanisms
2016The total friction torque acting on the bearing is caused by the bearing loads, viscous friction of oil, and seals of the bearing: $$ {M}_t={M}_l+{M}_v+{M}_s ...

Aircraft Wheel Bearing Failures … Why?
Scientific Lubrication, 1961RECENT post-accident investigations of an alarming number of wheel bearing failures in high performance aircraft have emphasized the need for a comprehensive and workable procedure for handling these bearings and bearing grease seals to eliminate these accidents.

Fatigue Failure Distributions for Ball Bearings
Journal of Lubrication Technology, 1973High reliability requirements of aircraft gas turbine mainshaft ball bearings necessitate reliable methods for estimating fatigue lives in the early failure region of the life dispersion. Economical and rapid comparisons of surface fatigue lives of modern track materials demand extrapolation from limited numbers of rig results, using a statistical ...

Incipient Failure Detection: Incipient Failure Detection in Ball Bearings
1969Abstract : This document reports the results of an investigation of incipient failure detection in ball bearings by means of acoustic monitoring techniques. The change of acoustic emanation strength with bearing condition was studied to determine if changes within the frequency spectrum monitored would manifest the onset of a bearing failure.
