摘要： A pulley engageable with a belt for use in a continuously variable transmission includes first and second pulley halves rotatable about an axis and relatively moveable in a direction of the axis. The pulley halves include truncated conical portions symmetrically opposed to each other and outer surfaces which are axially opposed to each other and sloped relative to the axis. The outer surfaces have a circumferential roughness average (Ra,y) measured in a direction (y) circumferential to the axis between approximately 0.15 and 1.0 micrometer. The outer surfaces have a radial roughness average (Ra,x) measured in a direction (x) radial to the axis, and a ratio Ra,x/Ra,y between approximately 0.5 and 2.5.

摘要： A belt for a continuously variable transmission (CVT) includes at least one continuous band supported against a contact face in a slot formed in each of a plurality of transverse elements of the CVT. The band has a surface positioned against the contact face. This surface is coated with chromium nitride by physical vapor deposition to reduce wear.
