CAM ASSEMBLY AND CAM POSITIONING DEVICE

Document Type and Number:

WIPO Patent Application WO/2002/053951

Kind Code:

A1

Abstract:

A device for positioning two plate cams of a metallic cam assembly for use in valve control of an internal combustion engine while deviating the fixing phase. The cam positioning device comprises a first cam positioning jig (24) provided with a positioning hole (31) of substantially the same shape as the contour of a first cam plate (10), and a second cam positioning jig (25) provided with a positioning hole (31) of substantially the same shape as the contour of a second cam plate (11). The cam positioning jigs (24, 25) are secured onto a positioning base (26) while arranging the positioning holes (31) at such relative positions as the orientation is differentiated by an angle a$g(a) depending on a specified phase difference of both cam plates (10, 11). At the time of assembling a cam assembly C, the first and second plate cams are fitted in the positioning holes (31) and then a cam shaft (12) is press fitted in a shaft insertion hole (22) thus assembling both plate cams at relative positions on the cam shaft separated by an angle $g(a) in the circumferential direction as much as a phase difference.
