Abstract

PURPOSE: To enable to change speed extremely smoothly by a method wherein the entire or a part of those parts of speed change pulleys which constitute belt-contacting surface are formed in specified curved shapes so as to maintain the traveling distance of a belt at a constant value.
CONSTITUTION: The entire of those parts of the speed change pulleys 12, 13 which constitute belt-contacting surfaces 10a, 11a are in specified curbed shapes, that is, the said parts have transverse cross-sectional configurations expressed by the formula, where X is the position of axis with the position of axis for the minimum rotation pitch radius taken as an original (0≤X≤2a); Y is the radius of rotation of the pulley; 2a is the effective range of the sheave; α is the angle of groove; C is the distance span between axese; d0 is the rotation pitch radius for a rotation ratio of 1:1.
