Title:
CAM SHAFT FOR OPERATING TAPPER FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS62199908
Kind Code:
A
Abstract:
A camshaft for actuating the valve tappets in internal combustion engines includes a shaft of a cold drawn pipe and a cam member. Both parts are connected to one another via an axially slotted tolerance ring. The bore of the cam member has an inwardly directed projection with essentially radially extending sides and a partially cylindrical surface having a curvature which corresponds to the curvature of the shaft. The edges forming the slot of the tolerance ring rest against the sides of the projection. The resulting circumferential bracing of the tolerance ring ensures a secure support of the cam member on the shaft. The projection is located in that angular range of the cam member in which the rotating cam during operation is in contact with the tappet to be actuated. Thus, the cam member is additionally braced by the cylindrical surface of the projection when the highest radial force acts on the cam member during a full rotation.
