Abstract
Endless metal belt particularly for a continuously variable transmission in which the tensile stresses during operation are decreased by incorporating compression stresses in at least the beld edge zones, for instance by plastic deformation of the belt material.
Claims12
Endless metal belt for being guided over pulleys and thereby subjected to varying bending and tensile stresses during operation,
- said belt having permanent compression stresses incorporated in at least edge zones of the belt, the belt edge zones being adjacent to longitudinal edges of the belt, for counteracting stresses to which the belt is subjected.
Process for forming an endless metal belt, comprising the steps of:
- (a) providing a metal belt;
- and
- (b) incorporating permanent compression stresses in at least edge zones of the belt, adjacent to longitudinal edges of the belt, the zones with incorporated compression stresses being formed by plastic deformation of the belt material.
