Structure of camshaft for engine

Abstract

Abstract PURPOSE:To aim at abatement in a collision noise, by feeding a bearing box, supporting an edge of a camshaft, with pressure oil, and energizing this camshaft in the specified axial direction all the time. CONSTITUTION:A camshaft 4 is driven via a helical crank gear 9. Both ends of this camshaft 4 are supported by bearing boxes 13 and 14. Pressure oil is fed to the lower bearing box 14 via a feed passage 23, and the camshaft 4 is energized in the specified axial direction all the time. A clearance T between the edge of the camshaft 4 and the bearing box 13 is almost brought to zero. With this constitution, a collision noise between the camshaft and the bearing box is reducible.
