Recently, cycloidal drives have been increasingly used due to their beneficial features, such as the implementation of a large transmission, efficiency, and high performance density. Production accuracy is inevitable in order to ensure the dynamicall...

The cutting fluids applied to the machining processes by the MQL process aim to reduce the machining temperatures and tool wear as well as improve the surface and dimensional finishing of the parts. To increase the efficiency of these fluids, graphen...

This article presents a test stand with a model high-speed spindle equipped with a system of active control of the preload of the bearings. This preload was changed by means of three piezo actuators. The work presents the results of tests during whic...

Surface Force Balance (SFB) experiments have been performed in a dry atmosphere and across an ionic liquid, combining the analysis of surface interactions and deformations, and illustrate that the mechanical deformations of the surfaces have importan...

Many researches are focused on the tribological performances of pure vegetable oil in order to replace the conventional mineral engine oils. This work investigates the influence of local moringa oil (noted VO) on the performances of lubricants formed...

The motivations for the move to electrified vehicles are discussed with reference to their improved energy efficiency, their potential for lower CO₂ emissions (if the electricity system is decarbonized), their lower (or zero) NO_x/particulate matter (...

In the context of targeted improvements in energy efficiency, secondary rolling bearing contacts are gaining relevance. As such, the elastohydrodynamically lubricated (EHL) roller face/rib contact of tapered roller bearings significantly affects powe...
