ABSTRACT:
The relation of the length h1 of the V surface of each metal element to the saddle primary thickness h2 is determined such that the strength of the metal element for the Hertz's pressure generated on the V surface 2 from the normal force P which acts on the V surface 2 when the element engages in the V-shaped groove of a pulley and the strength for the bending moment which is produced by the normal force P on the saddles 1 of the metal element are made substantially equal to each other. Also, the relation of the length of the V surface to the saddle primary thickness is determined such that the fatigue life by the Hertz's pressure which acts on the V surface and the fatigue life by the bending moment which acts on the saddles are made substantially equal to each other. The length h1 of the V surface, which is determined in the above mentioned ways, can be about 0.26-1.0 of the saddle primary thickness h2. Thus, the miniaturization and lightening of the element is achieved by this rational method which equalizes the fatigue life for the whole body of the element while providing the element with necessary strengths.
