Rolling element bearing failure analysis: a case study
R.K. Upadhyay - Indian School of Mines
(in lingua inglese)
In order to prevent fretting (false brinelling) in bearings of standby equipment, it is necessary to provide continuous slow rotation of shafts during operation while nearby machines is running [4]. Incrementin the angle of oscillation to secure roller overlap in order to drag fresh lubricantinto the area, ifthe surfaces can be separated by lubricant, fretting ofthe metal cannot occur. When the load is supported by lubricating film it can separate two surfaces from contacting each other with minimum friction. Recommendation towards use of larger bearing of higher capacity to reduce contact loads. It is also recommended that increase the hardness of the elements as much as possible.
