Definitions
- the invention is based on a wing made of plastic for a vane vacuum pump, according to the genus of Patent claim 1.
- the wing according to the invention with the features of Patent claim 1 is advantageous in that, firstly a mounting of separately produced items is eliminated on the other hand, the injection mold the final shape of the wing determined reproducibly with relatively tight tolerances.
- claim 2 embodiment is a Structure of the wing specified, at first the body the wing by injection molding, transfer molding or Forming presses and subsequently produced in the same or a separate injection mold the end-side part of the wing is manufactured.
- the development of the invention according to claim 3 is insofar advantageous, as one hand, the dimensional accuracy of the wing by a reduced influence of material shrinkage on end part is improved, on the other hand, the cost of the wing can be kept low when the Material of the end-side part is expensive.
- the measure marked in claim 4 provides an im During the manufacture of the grand piano in a simple way producible connection of the parts of the wing, especially if with the materials used for the Body and the end part of the wing no Material limit can be achieved.
- heat treatment of Body of the wing will be an increase in strength of the wing by the maximum achievable, spatial Degree of crosslinking of the molecular structures and a constancy of the Wing geometry due to stress reduction in the material structure and avoiding the Nachschwindens achieved.
- FIG. 1 shows a Spatial representation of a vane vacuum pump with a single wing
- Figure 2 as a spatial image of the body of Wing
- Figure 3 also as a room image with two end parts completed wings.
- a vane-type vacuum pump 10 shown in FIG. 1 has a reproduced without cover pump housing 11 with a Interior 12, in which a drivable rotor 13 eccentric is arranged.
- the rotor 13 is with a transverse Slot 14 for longitudinally movable guide of a plastic existing wing 15 provided.
- the wing 15 attacks slidable and sealing on a shell side Inner wall 16, on an end wall 17 and not on drawn lid of the pump housing 11 at.
- the Pump housing 11 further includes an intake manifold 18 a coat side opening into the interior 12 Inlet opening 19 and the end face an outlet opening 20th on.
- the intake manifold 18 is connected to a not shown Vacuum brake booster of a vehicle brake system connected.
- the operation of the vane vacuum pump 10 is known, so there is no further Explanation is needed.
- the lamellar wing 15 is made Plastic. Its shown in Figure 2 of the drawing Body 21 is made of a duroplastic. He is out a glass fiber reinforced phenol novolak molding compound or a material with comparable properties Injection molding, transfer molding or compression molding. This material is characterized by high mechanical and dynamic load capacity and oil resistance. His Material properties are in the temperature range of -40 ° C to + 150 ° C largely constant. The setting behavior of Material is very high over the life of the vacuum pump 10 low. The material properties of said thermoset can be improved by annealing the body 21 for several hours become.
- the wing 15 has molded end portions 22 and 23rd made of a high temperature resistant thermoplastic such as polyaryletherketone (PEEK) or a material with consist of comparable properties. This if necessary through a specially composed filler combination modified plastic has a high wear resistance and a low friction coefficient.
- the End-side parts 22 and 23 are by a Injection molding with the body 21 of the wing 15th united.
- the body 21, with opposite its broad sides 24, 25 and its narrow sides 26, 27 stepped recessed end portions 28, 29 is provided (see Figure 2), taken in a tool mold and with the mentioned thermoplastic material to that in Figure 3 form supplemented.
- the plastics used for the body 21 and the end portions 22, 23 of the wing 15 no or one are inadequate previously described embodiment of the wing 15 measures to achieve a positive connection between the mentioned Parts and the body of the wing 15 is provided.
- the end portions 28 and 29 of the body 21 have three longitudinal, straight grooves 30 half to three-quarter circular cross-section, which of the Material of the end-side parts 22 and 23 at Injection molding process are completed. This way will a lifting or releasing the end-side parts 22, 23 from Body 21 of the wing 15 prevented.
- Wing 15 In deviation from the above-described manufacturing process of Wing 15 can temper the body 21 without damage for the end-side parts 22, 23 after their union with done to the body.
- the manufacturing process can also be applied to vane vacuum pumps Find application where wings with only a single end sliding coating can be used.
