Abstract:
A metal V-belt, comprising:an endless belt shaped metal ring member and a plurality of metal element members supported along said metal ring member and that transmits power between a drive pulley and a driven pulley, said metal element members have a cross-sectional convex circular arc-shaped rocking face and incline forward and rearward about said cross-sectional convex circular arc-shaped rocking face relative to a traveling direction of said metal V-belt to contact a rear surface and a front surface of opposing front and rear metal element members, respectively, and further have a convex portion with a protruding height and a concave portion on front and rear surfaces and by means of engaging said opposing front and rear metal element members together, said convex portion and said concave portion can be lined up in a row at the front and rear surfaces on said metal element members, wherein a radius of curvature (R) of said rocking face is designed such that an allowable total clearance value between the total metal element members is less than the protruding height of said convex portion, the allowable total clearance value being a sum of a no-load stop clearance value and a compression stress clearance value, the no-load stop clearance value occurring between the metal element members during a no-load stop when said metal V-belt is stretched between said drive pulley and said driven pulley, the compression stress clearance value occurring between the metal element members due to compression stress acting on said rocking edge of said metal element members while said metal V-belt is transferring power.
