A mathematical model for calculating wear in machine elements is proposed. The model is developed for conforming as well as Hertzian type contact and includes correction for the presence of elastohydrodynamic fluid film forces. Resulting formulations are shown compatible with the Linear Wear Model and employ the same wear coefficient K. Statistical analyses of wear data accumulated from available sources to permit the formulation of probabilistic statements in connection with ...
The results of a detailed study of wear for carbon brushes, sliding bearings, friction clutches, gears, and rolling element bearings are described. The findings of a search and appraisal of the literature for each of these components are presented. A mathematical model is proposed for carbon brush wear, but found only to account for part of the observed variation in the given data. Further data analyses evaluate the effect of ...
