METHOD FOR INCREASING THE FATIGUE STRENGTH OF A PREDOMINANTLY STEEL MECHANICAL PART OF A WIND TURBINE AND/OR FOR REDUCING THE TENDENCY TO FORM WHAT ARE CALLED WHITE ETCHING CRACKS OR BRITTLE FLAKES IN SUCH STEEL MECHANICAL PARTS

摘要

Method for increasing the fatigue strength of a mechanical part of a wind turbine and/or for reducing the tendency to form what are called "white etching cracks" or "brittle flakes" in such a bearing, characterised in that it consists in making one or several of the bearing rings and/or roller elements concerned of the bearing at least partly of a hardened steel having a carbon content between 0,4 and 0,8 percent by weight.
