METHOD OF MANUFACTURING DISK FOR VARIATOR |
摘要 |
In a method of fabricating a variator disc, an outer periphery (5) of the input disc (D1), with a spline hole (4) thereof meshed with an input shaft (6), is finished using the input shaft (6) as a working reference. Subsequently, a race (2) is finished with high precisions using the outer periphery (5) as a working reference. There is an alternative method wherein a spline hole (4) with a machining allowance is precisely formed by means of a broach (X) prior to the heat treatment of a blank (B); after hardening the blank (B) by the heat treatment, tooth flanks (4a) of the spline hole (4) are precisely finished by means of a finishing broach (Y); and then, a race (2) of an input disc (D1) is precisely finished using the tooth flanks (4a) as a working reference. <IMAGE> |
