  • CVT pulley with engineered surface
    Patent number: 9714700
    Abstract: A pulley for a continuously variable transmission and a method of creating an engineered surface on an outer surface of a pulley of a continuously variable transmission, with the engineered surface engaging with a belt or chain of the continuously variable transmission. The method comprising the steps of: determining an actual engineered roughness (Rpk) on the outer surface needed to obtain a predetermined friction between the engineered surface and the belt or chain; and etching microgrooves in at least a portion of the outer surface to create the engineered surface by employing a laser to etch the microgrooves, the microgrooves being formed to a depth that produces the actual engineered roughness (Rpk).
    Type: Grant
