“…The development of defects in the rolling-element bearing interactions is mostly caused by surface fatigue wear. 43,51,52 As the fatigue load cycle increases, the variation in operating parameters, for example, film thickness, lubricant film stiffness, friction coefficient, traction coefficient, etc., leads to a propagating fault on the interaction surfaces of bearing components. The defects propagated on the bearing interaction surfaces alter the dynamic behaviour of the bearing system, thereby initiating variations in vibration levels.…”

“…However, higher operating temperatures lead to oxidation of the lubricant, thereby causing a negative impact on the bearing's lubrication. The present work is carried out in line with our previous work 22,34,43 in which roller-bearing damage assessment was conducted by considering film thickness, lubricant degradation and vibroacoustic analysis methods. However, this experimental investigation focuses on the role of bearing tribological parameters such as traction coefficient, lubricant film stiffness, load asperity ratio and dynamic response of the bearing system.…”

Rolling element bearings are commonly employed in rotating machinery to support rotating shafts. These machinery elements are vulnerable to failure due to increased friction and heat, which cause progressive wear on the rolling interaction surfaces of the bearing. The failure of bearings causes an unpredicted shutdown of equipment, leading to an increase in downtime and financial losses. Various condition monitoring techniques have been developed for periodic assessment of failure in roller-bearing systems. The focus of this work is to establish a relationship between surface fatigue wear, film thickness [Formula: see text], asperity load ratio [Formula: see text], lubricant film stiffness [Formula: see text] and traction coefficient [Formula: see text] parameters. A periodic assessment of the above-mentioned parameters was made on the test bearing, which was subjected to a fatigue test for 2000 h. The results acquired from the experimental study highlighted that, as surface fatigue wear on the bearing interaction surfaces and lubricant degradation occurred with an increase in fatigue load cycles, the asperity load ratio [Formula: see text] and traction coefficient [Formula: see text] parameters showed a gradual rise in trend which further resulted in a difference in the dynamic behaviour of the bearing system.

“…A study about wear evolution in the mixed elastohydrodynamic lubrication is presented in Winkler et al 20 An experimental fatigue life test was carried out with the aim of relating surface roughness and wear during bearing operation. 21 Based on DIN 281, a new method for estimating the equivalent fatigue stress in rolling element bearings is applied to a high fatigue cycle multiaxial model. 22 The wear rate was analyzed in Rahul et al 23 in solid lubricated rolling bearings using an experimental technique under high vacuum conditions and computational modeling.…”

Roller bearings are widely used in machinery. Keeping the contact surfaces of bearings properly lubricated strongly mitigates wear effects, improving bearing fatigue life. Therefore, systematically selecting the lubricant fluid that satisfies bearing operation conditions allows the lubricating layer to be able to carry the applied load, the operating temperature, and the roughness on contact. The nonlinear constrained optimization method is used for lubricant selection, seeking to find the fluid that best fits the bearing operation conditions. Roller bearing lubrication is characteristically elastohydrodynamic (EHL); namely, the Hertz theory describes the load applied on the contacts of a cylindrical roller bearing, and the Stribeck condition classifies the tribological condition of the surfaces in contact. This work concludes that roughness and speed are the most important parameters to consider when choosing a fluid lubricant.
