Title:
DRIVE BELT AND CONTINUOUSLY VARIABLE TRANSMISSION USING THE DRIVE BELT
Document Type and Number:
Japanese Patent JP2004125173
Kind Code:
A
Abstract:

To extend the operation life of a known belt without increasing cost.

This drive belt comprises at least one continuous band 11 and the array of plate-like traverse elements 20 engaged with each other in the longitudinal direction of the connection band 11. The continuous band 11 is curved with a crowning radius of curvature Rcrown in the traverse direction to impart internal stress distribution to determine a curling radius of curvature Rcurl when the cut continuous band 11 is curved in the longitudinal direction. The ratio Rcurl/Rmin of the curling radius of curvature Rcurl to the minimum radius of curvature Rmin and a preliminary bending coefficient fPB meet the requirement of the following expression.fPB=(δi+δo)/δo. Where, δi: maximum vertical distance in radial direction between neutral line NL in cross section of band 11 where stress by absolute longitudinal bending is zero and innermost surface 12, and δo: maximum vertical distance in radial direction between the neutral line NL and outermost surface 13.
