Definitions
- the invention relates to a vane for a single vane vacuum pump, which has a pot-shaped housing and is provided with a rotor mounted eccentrically and rotatably in the housing, the vane in the rotor being slidably mounted orthogonally to the axis of rotation and with its free ends resting on the inner peripheral surface of the housing.
- Vacuum pumps with such a structure are known. They generally have a housing made of metal, in which a rotor is rotatably mounted and in which the working spaces are formed. For example, the rotor is rotated by the engine of a motor vehicle. It is also known that these rotors consist of metal and in particular of sintered metal. Due to the high weight of the rotor, it has a large moment of inertia, which means that the power consumption of the vacuum pump is undesirably high. In addition, the wing is made of solid material, which further increases the moment of inertia. The invention is therefore based on the object of providing a vacuum pump, in particular a single-wing vacuum pump, which has a lower power consumption.
- the configuration of the wing according to the invention achieves the essential advantage that the weight of the wing is reduced without the bending rigidity being significantly influenced.
- the truss structure has the advantage of stiffening the wing in a simple manner so that it can easily absorb and support the bending forces that arise during the pumping process.
- the truss structure extends into the wing tip. As a result, the moment of inertia of the wing is reduced particularly strongly, so that lower forces are required for acceleration and deceleration.
- the truss structure has diagonal walls that end in the outer wall.
- the diagonal walls are at an angle to Stand outside wall, which is determined from the respective application for the maximum load case.
- the diagonal walls are advantageously at an angle of 45 ° to the outer wall.
- a simple structure of the wing results from the fact that a maximum of two diagonal walls meet in a truss node. In this way, in particular in the case of injection-molded wings, material accumulation in the truss node is avoided.
- the wing is preferably hollow, apart from the diagonal walls. These cavities also serve to absorb lubricants in the form of oil, so that the oil is also permanently available for sealing purposes.
- a partition is provided in the longitudinal axis of the wing, which extends orthogonally to the outer wall.
- This partition increases the overall weight of the wing only insignificantly, since it has relatively small dimensions. However, it increases the bending stiffness of the wing.
- openings can be made relatively small and also have the advantage that lubricant can pass from one side to the other side of the partition.
- partition, the outer wall and the diagonal walls form blind holes with an essentially triangular cross section. Structures of this type are relatively stiff and yet easy to manufacture.
- Figure 1 is an exploded view of the vacuum pump
- Figure 2 is a perspective view of the wing; and Figure 3 is a perspective view of the wing, partially cut away.
- reference numeral 10 designates a vacuum pump as a whole, in which the housing 12 is shown without a housing cover.
- the housing 12 has a suction connection 14 which opens into an interior 16.
- the rotor 18 is constructed in two parts and has a rotor axis 22 and a rotor housing 24.
- the rotor axis 22 passes through the housing 12, in particular a bottom 26 of the interior 16 via a drive opening 28 and protrudes with a rectangular section 30 on the rear side from the housing 12, via which it is set in rotation (by means of a drive, not shown).
- the drive opening 28 is provided with suitable sealants, so that neither lubricant can escape nor air and / or dirt can enter the interior 16.
- the wing 20 which is shown in detail in FIGS. 2 and 3, has an outer wall 32 which faces the inner circumferential surface 34 of the interior 16.
- the wing 20 rests with its free ends 36 on this inner peripheral surface 34.
- the outer wall 32 is closed, that is to say without openings leading to the opposite side, and surrounds a truss structure 38, which forms the core of the wing 20 forms.
- the truss structure 38 has a multiplicity of diagonal walls 40, two of which meet in a truss node 42.
- the diagonal wall 40 and the outer wall 32 enclose an angle 44 of 45 °.
- the diagonal walls 40 are arranged in a W-shape.
- the outer wall 32 and two diagonal walls 40 each enclose an essentially triangular opening 46.
- This opening 46 can either be continuous or it can also be interrupted by a partition 48, as can be seen in FIG. 3.
- This partition 48 extends in the direction of the longitudinal axis 50 of the wing 20 and in turn has openings 52 which connect the two openings 46 to one another.
- the openings 46 can also be slightly conical, so that the wing can easily be removed from an injection mold.
