SOME CONSIDERATIONS REGARDING THE FATIGUE CRACKS PRODUCING PITTING WEAR OF GEARS
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2017, Vol 62, Issue 2
Abstract
In this article some aspects of the fatigue cracks that have the consequence of pitting wear appearance on the spur gears are presented. The main mechanisms leading to the fatigue cracks, crack nucleation, propagation of cracks of small length, as well as the propagation of cracks on long lengths, respectively, will also be analyzed. The stress field, the growth rate as well as the spread of fatigue cracks will be considered.
