Abstract (en)
[origin: WO2015097277A1] The invention relates to a flexible ring (32) made from steel for use in a drive belt (3)for a continuously variable transmission, which ring (32) is provided with a surface layer including only crystals with a grain size of less than 0.1 micron. By such nanocrystalline surface layer the fatigue strength of the conventional ring (32) could be improved upon.
