Japanese Patent JP4323357
Kind Code:
B2
Abstract:
A process for producing a pulley for a belt drive CVT, including subjecting tapered surfaces of a preform of at least one of input and output pulleys to surface hardening, subjecting the surface-hardened tapered surfaces of the preform to hard turning to form microgrooves radially spaced from one another thereon, between which microprojections are formed, and reducing a height of the microprojections. Alternatively, a process for producing a pulley for a belt drive CVT, including subjecting tapered surfaces of a preform of at least one of input and output pulleys to surface hardening, subjecting the surface-hardened tapered surfaces of the preform to shot peening, and subjecting the shot-peened tapered surfaces of the preform to finishing to form microgrooves having a substantially equal pitch thereon.
