THE QUESTIONS OF SPINNING FRICTION IN AN ELASTIC POINT OF CONTACT
Journal Title: Tribologia - Year 2010, Vol 232, Issue 4
Abstract
The paper presents tangential stress as a result of friction change in the stress distribution in upper surface layer. The increase of this stress may be up to 100% at field of acting greater to 30%. It causes plastic deformation of mating surfaces and their intensive wear during work.<br/><br/>

FINITE ELEMENT ANALYSIS OF THE THERMAL BEHAVIOUR OF SINGLE-DISC CLUTCHES DURING REPEATED ENGAGEMENTS
Most of the failures in the sliding systems occur due to the high thermal stresses, which generated at the interface between the contacting surfaces due to sliding between parts, such as friction clutches and brakes. In...
FUNDAMENTALS OF THE STOCHASTIC DESCRIPTION OF THE HYDRODYNAMIC THEORY OF LUBRICATION
The aim of this paper is the presentation of basic principles referring to the application of stochastic methods during the solution of hydrodynamic lubrication problems for slide journal bearings, taking into account th...
BEARING SYSTEMS OF WIND TURBINES – MAINTENANCE PROBLEMS
In operation of wind turbines of conventional design (with gear), a high failure rate of gears, especially the cylindrical roller bearings of the high-speed shafts, are observed. In Poland, the owner of a large wind farm...
IDENTIFICATION OF FRICTION CONDITIONS IN HUMAN JOINTS
The purpose of the paper is to explain the friction conditions and the lubrication mechanism in healthy joints, based on rheological tests of synovial fluid and the identification of structures and the shape of articular...
Zwiększenie trwałości eksploatacyjnej węzłów tarcia przez zastosowanie powłok DLC typu a:C:H oraz a:C:H:W
W artykule przedstawiono wyniki badań struktury oraz testów triologicznych powłok DLC typu a:C:H oraz a:C:H:W. Powłoki otrzymywano techniką PACVD na elemenach ze stopu Co-Cr-Mo. Analizę struktury powierzchni i jej elemen...
