ROTARY ASSEMBLY

WIPO Patent Application WO/2006/077914

A1

A rotary assembly, wherein the cam piece (3) of a camshaft (1) comprises a circular base circle part (31) surrounding a drive shaft (2) in a mounted state. A pair of sleeve parts (33) extending from both end faces of the base circle part (31) in its insertion direction are formed on the cam piece. Inner holes (34) are formed in the sleeves (33) at the contact parts on the outer peripheral surface of the drive shaft (2), and a plurality of grooves (35) extending in a drive shaft (2) insertion direction are formed in the inner hole (34). Also, projected lines (37) extending in the drive shaft (2) insertion direction are formed in the inner hole (34), and a keyway (21) engaged with one of the projected lines (37) is formed in the outer peripheral surface of the drive shaft (2). By engaging the projected line (37) with the keyway (21) in the enlarged state of the inner hole (34) by heating the cam piece (3), the drive shaft (2) is inserted into the inner hole (34) while positioning in its rotating direction to firmly fix the cam piece (3) onto the drive shaft (2).
