“…Firstly, the information about rolling bearing, including dimensional parameters, material parameters, and loading spectrum, is collected. Then, with the aid of quasi‐static approach 45 and Hertz contact theory, the contact stress of the bearing corresponding to each loading condition and the interaction factor are calculated, as shown in Figure 6B. Finally, the cumulative damage and fatigue life of rolling bearings during operation are calculated.…”

During the use of rolling bearings in wind turbines, aero engines, and other equipment, they often operate under variable operating and loading conditions. The practice has shown that the sequence of these loads and their interaction has a significant impact on the fatigue life of rolling bearings. In order to better understand this issue, a modified nonlinear fatigue damage accumulation model, which considers the influences of both load sequence and load interaction, is proposed in this paper and verified using the fatigue testing data for six materials. Then, the verified model was applied to evaluate the fatigue damage accumulation and fatigue life of a rolling bearing. The results have shown that, compared with the existing models, the proposed model can more accurately predict the damage accumulation and fatigue life of the rolling bearing under variable loading conditions.

“…24 Wang et al presented models to analyze the relation between the normal pressure imposed on the rolling ball and its gyroscopic torque with or without race control hypothesis and then the friction coefficient was calculated. 20,25,26 Considering the effect of the rough surface, the quasi-dynamic model of ACBB was introduced by Wang to investigate the influences of the race surface on the subsurface stress field. 27 Some scholars paid attention to the research on the nonlinear vibration characteristics and stability of the rotor-bearing system based on the load distribution, contact angle and stiffness of ACBB.…”

“…Furthermore, the sphere-outer race contact load could exceed the value of the sphereinner race contact load due to the centrifugal and gyro effect. 23 Based on the previous works, the friction of the sphere-race contact caused by centrifugal and gyro effect is inevitable 3,25,26 and should not be ignored when evaluating the RCF life of the rolling bearing. However, there are few quantitative and theoretical reports on the issue.…”

In this paper, a theoretical model is proposed to analyze the friction effect on the rolling contact fatigue (RCF) life of the angular contact ball bearing (ACBB). Firstly, the quasi-static model without race control hypothesis is introduced to study the load characteristics of the ACBB under different loading conditions. Then, the friction coefficient is quantitatively calculated by analyzing the relation between the gyroscopic torque and the sphere-race contact load. The effects of the axial load, radial load, torque load and rotating speeds on the friction coefficient, the maximum value of the sub-surface von Mises stress (SSVS) and the maximum peak-peak value of the sub-surface shear stress (SSSS) are subsequently investigated. The results show that they can significantly affect the friction coefficient and further influence the stress field beneath the contact surface. Further studies illustrate that the friction coefficient cannot affect the maximum peak-peak value of the SSSS but can change the distribution of the SSVS field. The relative RCF life of the sphere-race contact is calculated and the published studies confirm the accuracy of the calculation.

“…Though the skidding behavior under pure axial load can be predicted by introducing the theory of elastohydrodynamic lubrication(EHL), 23 the influence of cage and several inertia items are still ignored in this model. In recent years, many new treatments have been proposed to remove the classical restrictive race control assumptions, 4,24 while this model is no longer appropriate when the interactions between the cage and other bodies need to be considered. Taking the time-varying characteristics into consideration, the dynamic model has also been used to analyze the bearing characteristics, such as vibration 25 and roller convexity excursion.…”

To study the angular misalignment effects on the high-speed micro ball bearing which is applied to the dental handpiece, an improved five-degree-of-freedom quasi-dynamic model considering full multibody interactions is established in this paper. Then the modified fatigue life model presented by Jones is adopted to further evaluate the influence of angular misalignment on the reliability of the bearing. The results show that the angular misalignment significantly influences the contact load and contact angle distributions as well as the skidding behavior under both pure axial load and combined axial and radial loads. After comprehensive comparison, it is found that the impacts of angular misalignment on total power loss and bearing fatigue life are different under the two types of loads. Under pure axial load, the total power loss increases consistently and the bearing fatigue life decreases significantly when the absolute value of angular misalignment becomes larger. However, under combined axial and radial loads, the effects of angular misalignment are rather complicated and the direction of angular misalignment turns out to be a key influencing factor.
