Embodiment Construction

[0019] The vacuum pump 1 is shown in a very simplified manner, and the vacuum pump 1 is in image 3 partially shown in. The vacuum pump 1 comprises a housing 5 with a bearing region 6 .

[0020] The vacuum pump 1 is in the form of a vane pump and is used, for example, to generate a vacuum in a vacuum chamber of a brake booster. For this purpose, a rotor 10 is arranged rotatably about an axis of rotation 12 in the housing 5 of the vacuum pump 1 .

[0021] The axis of rotation 12 of the rotor 10 coincides with the longitudinal axis of the rotor 10 . The rotor 10 is driven by, for example, a drive shaft, and the rotor 10 guides blades which are disposed in blade positioning slots 18 in the rotor 10 . When the rotor 10 rotates about its axis of rotation 12, the volume of the suction chamber of the vacuum pump increases, so that the working medium is sucked into the suction chamber. At the same time, the volume in the pressure chamber of the vacuum pump is reduced, so that the ...

Abstract

The present invention proposes a vacuum pump, the vacuum pump having a housing made of light metal, in the housing in a rotatable manner is mounted a rotor made of light metal, the rotor drives at least one blade, wherein the rotor is made of light metal and has at least three different diameters along its axis of rotation.

Description

technical field [0001] The present invention is based on the priority of patent application DE 102015216104.8, the entire content of which is hereby incorporated by reference. [0002] The invention relates to a vacuum pump of lightweight construction with components made of aluminum. Background technique [0003] A vacuum pump with a drivable rotor is known from the international application WO 01 / 48381 A2, wherein at least one vane in the housing can be rotated by means of the drivable rotor. The rotor and / or blades are made of aluminum or aluminum alloys. The rotor is manufactured by machining, or by forming instead of machining, preferably by die casting or extrusion. At least part of the housing of the vacuum pump is likewise made of aluminum or an aluminum alloy. Anodizing the rotor and / or blades. During the anodizing process, a protective oxide layer is formed on aluminum or aluminum alloys. This protective oxide layer serves to provide protection against wear. ...
