Abstract: A tapered roller planetary traction drive based on a so-called zero-spin design was built for performance evaluation. The traction drive demonstrated, in many aspects, superb performance ...

Abstract: A novel design of planetary tapered roller traction drive was described. The design eliminated the spin motion induced sliding, offering high mechanical efficiency and improved wear performance. ...

Abstract: A means of evaluating the surface roughness effect on contact fatigue life has been proposed. To account for stress variations caused by random surface roughness, an effective stress concept ...

Abstract: This paper presents a numerical solution for the elastohydrodynamic lubrication in point contacts, using optically measured three-dimensional rough surface profiles as input data. The multi-grid ...

Abstract: A general transient model for microelastohydrodynamic lubrication with Eyring fluid was established in this paper to describe the basic processes involved in thin film lubrication with rough ...

Abstract: The transient elastohydrodynamic lubrication (EHL) process of cam-tappet pair in I. C. engine is analyzed with a full numerical method. The variations of pressure distribution and film profile ...

Abstract: An accurate, robust, and efficient method for elastic contact of rough surfaces is presented. The method converts the contact problem into an unconstrained energy minimization problem. The equality ...

Abstract: Transient EHL analysis for line contacts with measured surface roughness is performed by using the multigrid method. Results show that the transient effect, induced by surface roughness, has a ...

Abstract: A fast calculation model for the pressure distribution in EHL line contacts between rough surfaces is presented. Comparison between the results obtained from the model calculation and numerical ...
