Hydraulic camshaft adjusting device for internal combustion engine, has rotor having hub which is integrally fixed with four adjoining blades, such that hub and blades are formed as integral monolithic structure

摘要

The hydraulic camshaft adjusting device (1) has a rotor (3) comprising a hub (4) which is integrally fixed with four adjoining rotor blades (7), such that the hub and blades are formed as integral monolithic structure (14). The front and rear side surfaces (17,18) of each blade are radially extended outward of stator (2) from the hub. The rotor blades are tapered radially outward. The integral monolithic structure is made from metal sheet or sinter component. The thickness of blade is formed homogeneously in the axial direction.
