The targeted insertion of compressive residual stresses can positively influence the fatigue life of rolling element bearings. Adapted manufacturing processes such as hard turning and deep rolling can help optimising the ...

The power control of wind turbines is usually realized via a change in the pitch angle of the rotor blades. Pitching facilitates the exact control of the turbines and the reliable deceleration of the rotor when required. ...

Bio-lubricants have demonstrated promising tribological and physical properties, suggesting their potential advantages in the lubrication of critical machinery components. This study investigates the impact of using blended ...

Grease-lubricated rolling element bearings can suffer from wear due to lubricant starvation under certain oscillating operating conditions. Especially for large-scale slewing bearings, such as blade bearings in wind turbines, ...

Locally adapted properties within a machine component offer opportunities to increase the performance of a component by using high strenght materials where they are needed. The economic production of such hybrid components ...

The application of microdimple-textured surfaces for rolling bearings is not very common but can be beneficial for various usage scenarios. In contrast to the applications for plain bearings or cylinder running surfaces, ...

In recent years, graphene-based lubrication was in the focus of nano-and microtribological studies. While the sliding properties of graphene based dry lubrication were previously investigated on the nano-and micro-scale, ...

Components subject to rolling contact fatigue, such as gears and rolling bearings, are among the fundamental machine elements in mechanical and vehicle engineering. Rolling bearings are generally not designed to be ...

Small oscillating amplitudes (~0. 1°) and larger (> 1°) can both lead to wear, w hich complicates the evaluation of the operating conditions. In this work, a simulation model is used to discuss critical amplitudes. The ...
