摘要： A traction drive rotary assembly including a plurality of rolling elements having traction contact surfaces associating with each other to transmit power between the rolling elements. At least one of the traction contact surfaces has a surface microstructure including grooves and protrusions alternately arranged. The surface microstructure is represented by an unfiltered primary profile curve including recesses and projections corresponding to the grooves and the protrusions. 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.
