Embodiment Construction
[0037] figure 1 The rotor 1 for a camshaft adjuster is shown in cross-section. The rotor 1 has a rotor base 3 with four rotor blades 5 extending radially outward. In the installed state, when the rotor 1 is positioned in the stator, the rotor blades 5 are used to divide each pressure chamber of the camshaft adjuster into two adjacent hydraulic regions. in Figure 4 The camshaft adjuster is shown in.
[0038] The rotor base 3 and the rotor blades 5 are integrally made of a metal material by a sintering method. Unlike the two-part manufacturing method in which the rotor blades 5 are held, for example, in grooves of the rotor base body 3, the possible leak locations are minimized by an integrated method. In addition, the sintering method provides the possibility of using an automated process flow, so it is cheap and easy to implement. Based on the dimensional accuracy of this method, the rotor 1 can be manufactured in such a way that the radial leakage gap between the blade end ...
