Abstract
Ductility of belt material is increased at least at one edge of an endless metal belt, thus reducing the likelihood of premature failure of the belt. The inner region of the belt maintains the inherent strength of the metal. The endless metal belt so formed is particularly useful as a driving member for a continuously-variable transmission.
Claims26
An endless metal belt comprising a center region between two edge regions, wherein a ductility of at least one said edge region is greater than a ductility of said center region, wherein ductility is measurable as percent elongation of a two inch pull.
An endless metal belt assembly comprising at least two independently movable nested endless metal belts comprising a center region between two edge regions, wherein a ductility of said edge regions is greater than a ductility of said center region, wherein ductility is measurable as percent elongation of a two inch pull.
A process for treating an endless metal belt which has a center region between two edge regions, comprising treating at least one said edge region to increase a ductility of said edge region above a ductility of said center region, wherein ductility is measurable as percent elongation of a two inch pull.
