CAM SHAFT
Document Type and Number:
Japanese Patent JPS6181501
Kind Code:
A
Abstract:
PURPOSE:To reduce the number of machining processes, by installing a projection and a groove at a position being dislocated out of a nose part as far as an angle of a half angled by the nose part of both suction and exhaust cam, in case of such one which positions a cam lobe to a steel pipe with the projection and the groove. CONSTITUTION:A suction cam 31 and an exhaust cam 32 both are constituted of a sintered alloy or the like, and positioned on a steel pipe by a combination of a projection and a groove. The projection and the groove are formed in angle beta position from a nose part in relation to an angle alpha made by a straight line connecting the nose part between the suction cam 31 and the exhaust cam 32 and a steel pipe center, and beta comes to a half of alpha. The same groove or projection is usable for both suction and exhaust cams and, what is more, a cam lobe also rotates a half-turn and inserted thereinto so that the same thing is usable, getting off with the number of machining processes reduced.
