Definitions
- a cell compressor which is equipped with plastic fins or blades. While that part of the fins which is assigned to the rotor of the cell compressor consists of a poor quality material, the end part of the fins which is assigned to a jacket wall of the compressor housing, on the other hand, should consist of a highly wear-resistant material.
- the parts of the lamellae are manufactured separately from one another and connected to one another by methods such as gluing, riveting and welding. Furthermore, the two lamella parts can also be pressed together during the manufacturing process.
- a multi-part lamella construction has the disadvantage that the individual tolerances of the lamella parts add up.
- the development of the invention according to claim 3 is advantageous in that on the one hand the shape accuracy of the wing is improved by a reduced influence of the material shrinkage at the end part, on the other hand the costs of the wing can be kept low if the material of the end part is expensive.
- the measure characterized in claim 4 represents a connection of the parts of the wing which can be produced in a simple manner in the course of the manufacture of the wing, in particular if the materials used for the Body and the end part of the wing no material bond can be achieved.
- FIG. 1 shows a three-dimensional representation of a vane cell vacuum pump with a single vane
- FIG. 2 shows the body of the wing as a spatial image
- FIG. 3 also shows the vane completed with two end parts.
- a vane cell vacuum pump 10 shown in FIG. 1 has a pump housing 11 shown without a lid, with an interior 12 in which a drivable rotor 13 is arranged eccentrically.
- the rotor 13 is provided with a transverse slot 14 for the longitudinally movable guidance of a wing 15 made of plastic.
- the wing 15 slidably and sealingly engages an inner wall 16 on the casing side, an end wall 17 and the cover (not shown) of the pump housing 11.
- the pump housing 11 also has an intake port 18 with an inlet opening 19 opening into the inner side 12 and an outlet opening 20 on the front side.
- the intake port 18 is not shown Vacuum brake booster connected to a vehicle brake system.
- the functioning of the vane vacuum pump 10 is known, so that no further explanation is required for this.
- the lamellar wing 15 is made of plastic. Its body 21 shown in FIG. 2 of the drawing is made of a thermoset. It is made of a glass fiber reinforced phenol novolak molding compound or a material with comparable properties
- Injection molding injection molding or compression molding.
- This material is characterized by high mechanical and dynamic resilience and oil resistance. Its material properties are largely constant in the temperature range from -40 ° C to + 150 ° C. The setting behavior of the
- thermoset is very low over the life of the vacuum pump 10.
- the material properties of the thermoset mentioned can be improved by annealing the body 21 for several hours.
- the wing 15 has molded-on end parts 22 and 23, which consist of a high-temperature-resistant thermoplastic such as polyaryl ether ketone (PEEK) or a material with comparable properties.
- PEEK polyaryl ether ketone
- This plastic possibly modified by a specially designed filler combination, has a high wear resistance and a low coefficient of friction.
- the end parts 22 and 23 are combined with the body 21 of the wing 15 by an injection molding process.
- the body 21, which is provided with end sections 28, 29 which are stepped back in relation to its broad sides 24, 25 and its narrow sides 26, 27 (see FIG. 2), is received in a tool form and with the aforementioned thermoplastic material to that shown in FIG. 3 Completed form.
- the two form end parts 22 and 23 of the wing 15 semi-cylindrical shells with a small layer thickness, which envelop the end sections 28 and 29 of the body 21 as a sliding coating and are flush with the narrow sides 26 and 27 of the body 21 at least.
- the plastics used for the body 21 and the end parts 22, 23 of the wing 15 have no or an insufficient material bond, measures for achieving a positive fit between the mentioned parts and the body of the wing 15 are provided in the above-described embodiment of the wing 15.
- the end sections 28 and 29 of the body 21 have three longitudinal, straight grooves 30 of semi-circular to three-quarter circular cross-section, which are filled by the material of the end parts 22 and 23 during the injection molding process. In this way, lifting or loosening of the end parts 22, 23 from the body 21 of the wing 15 is prevented.
- the annealing of the body 21 can also take place without damage to the end parts 22, 23 after they have been combined with the body.
- the manufacturing process can also be used in vane cell vacuum pumps, in which vanes with only a single sliding surface on the end are used.
