CONTINUOUSLY VARIABLE TRANSMISSION METAL BELT, METHOD FOR MANUFACTURING METAL RING OF CONTINUOUSLY VARIABLE TRANSMISSION METAL BELT, AND METHOD FOR MEASURING SHAPE OF METAL RING OF CONTINUOUSLY VARIABLE TRANSMISSION METAL BELT

摘要

A continuously variable transmission metal belt includes a metal ring assembly and metal elements. The metal ring assembly includes stacked endless metal rings. Each of the stacked endless metal rings includes a flat peripheral surface and a substantially semicircular end face. The substantially semicircular end face is connected to an end of the peripheral surface in a width direction of each of the stacked endless metal rings. The metal elements are supported on the metal ring assembly. A displacement Z of the end face is smaller than or equal to 0.1R. The displacement Z is defined as Z=R−H. R is a radius of an imaginary circle that passes through a contact point between the peripheral surface and the end face and that is tangent to the end face. H is a distance from a center of the imaginary circle to the peripheral surface.
