Title:
METHOD FOR MANUFACTURING VARIATOR PART OF CONTINUOUSLY VARIABLE TRANSMISSION AND CHUCK DEVICE FOR VARIATOR PART MANUFACTURE
Document Type and Number:
WIPO Patent Application WO/2012/077354
Kind Code:
A1
Abstract:
Disclosed is a method for manufacturing a variator part of a continuously variable transmission comprising: a step of performing preceding machining of a power transmitting surface (4) and a spline hole while leaving machining allowance on a work (10) of a variator part; a step of performing heat curing treatment of the work (10); a step of performing finish machining of a plurality of spline grooves (3b) configuring the spline hole of the work (10); a step of closely bringing a part (15) of a chuck (12) mounted on a lathe into contact with the plurality of spline grooves (3b) to clamp the work (10) coaxially with a rotating shaft of the chuck (12); and a step of performing finish machining of the power transmitting surface (4) of the work (10) using the spline grooves (3b) of the work (10) clamped to the chuck (12) as a machining reference.
