Each projection includes a portion located higher than a center line of the unfiltered primary profile curve and having a shape selected from a generally trapezoidal shape with rounded corners, a generally crowning shape, a generally elliptic arc shape, a generally sinusoidal shape and a generally triangular shape with a rounded apex. A ratio &lgr;/AMP of a wavelength &lgr; of the unfiltered primary profile curve to a half depth AMP of the recess is in a range of 50-400.

摘要： A continuously variable transmission including discs made of heat-resisting bearing steel, and rollers made of ceramics. The heat-resisting bearing steel contains 0.8-1.5 wt % of C, 0.5-2.0 wt % of Si, 0.3-2.0 wt % of Mn, 1.3-1.98 wt % of Cr, and 0.3-1.0 wt % of Mo, (Si+Mo) being 1.0 wt % or more. Because the rollers are made of ceramics superior in heat resistance, the toroidal type continuously variable transmission, even if used under high load and high rotational speed, is free from occurrence of sticking between discs and rollers and damage of the raceway surfaces.

摘要： A toroidal continuously variable transmission system of the present invention is provided with an input disk, an output disk and power rollers. The input and output disks have traction surfaces defined between a small-diameter portion and a large-diameter portion and having an arc-shaped concave section.

At least one of the input disk, the output disk and the power rollers is formed of an alloy steel which contains 0.15 to 2.0% by weight of Mo. The alloy steel is subjected first to carburization or carbonitriding processing executed at a temperature not lower than 1,000° C., and then to hardening and tempering. The alloy steel has a surface carbon content of 0.8 to 1.4%.
