Purpose Bearings in electric machines often work in high speed, light load and vibration load conditions. The purpose of this paper is to find a new fatigue damage accumulation rating life model of ball bearings, which is expected for calculating fatigue life of ball bearings more accurately under vibration load, especially in high speed and light load conditions. Design/methodology/approach A new fatigue damage accumulation rating life model of ball bearings considering time-varying vibration load is proposed. Vibration equations of rotor-bearing system are constructed and solved by Runge–Kutta method. The modified rating life and modified reference rating life model under vibration load is also proposed. Contrast of the three fatigue life models and the influence of dynamic balance level, rotating speed, preload of ball bearings on bearing’s fatigue life are analyzed. Findings To calculate fatigue rating life of ball bearings more accurately under vibration load, especially in high speed and light load conditions, the fatigue damage accumulation rating life model should be considered. The optimum preload has an obvious influence on fatigue rating life. Originality/value This paper used analytical method and model that is helpful for design of steel ball bearing in high speed, light load and vibration load conditions.

“…Other sources contributing to heat generation, e.g., in high-speed rolling bearings, include the inlet reverse flow, lubricant churning in bearing cavities, as well as friction between rolling element cages. The generated heat propagates through the bearings, inducing alterations in the temperature field, thereby exerting an influence on the overall performance of rolling bearings [1], the limiting speed [2], and even their service life [3]. Therefore, the measurement of temperature rise has been widely adopted as an important parameter in bearing tests for evaluating lubrication properties [4,5] and serves as a failure criterion for lubricants or rolling bearings [6,7].…”

The present study focuses on investigating the influence of oil and solid body temperatures on elastohydrodynamic lubrication (EHL) film formation. Experimental and numerical simulation methods are employed to examine three heating methods: oil and ball heating, disc heating, and entire system heating. A preliminary comparison between the measured results and numerical simulations confirms the impact of heating methods on film formation while validating the availability of the numerical models. Further numerical analysis reveals that in the case of oil and ball heating, the temperature gradient induced by differences in solid body temperatures plays a more significant role in film formation compared to the conventional thermal-viscosity wedge effect caused by EHL film shear. This effect is further amplified at large sliding–rolling ratios and in steel–steel contacts. The overall film formation is primarily governed by the oil inlet temperature, whereas local film formation characterized by a dimple shape is influenced by both thermal gradient effects and thermal-viscosity wedge effects. This study provides valuable insights for selecting appropriate heating methods in experiments as well as understanding how temperature differences affect film formation in practical engineering.

“…They discovered that the overall frictional power consumption of the bearing increased with an increase in the sliding rate. Cui and Zhang [13] analyzed the minimum load for sliding and the maximum critical load for the overheating of rolling bearings based on the self-developed high-speed rolling bearing test bench. Russell et al [14] conducted an experimental study on the effects of bearing fitting on the bearing internal clearance.…”

Bearing is an important transmission component of aero-engine under high-speed and heavy-load conditions. To design a roller bearing with high loading capacity and reliability, it is essential to pay attention to the relationship between external load state (reaction force) and internal load distribution (load distribution). Therefore, a measurement method for bearing reaction force is proposed in this study via load distribution and radial basis function neural network. Different from conventional static reaction force measurement methods, both of direction and magnitude of the reaction force were considered in the proposed method without modifications to bearing. Firstly, an experimental system was designed to investigate the load distribution in a roller bearing under different reaction forces using strain variation measurement. Then, finite element analysis was conducted and simulation results of the strain variations at three interested points match well with the experimental measurements. Finally, radial basis function neural network with strong nonlinear fitting ability is applied to construct the mapping relationship between strain variation and reaction force. The results show that the proposed method can predict the reaction force with high accuracy based on the strain variation at three measuring points.
