Definitions
- the invention relates to a housing for a drive shaft, a stator and a rotor comprising, as e.g. in electric motors, generators, and other drives, in particular a housing with, for example, two bearing plates, one for the drive shaft with the rotor and one for the stator. Moreover, the invention relates to a manufacturing method for the production of such a housing, as well as the use of a fiber reinforced plastic.
- the bearing and housing of a drive shaft with a stator is conventionally made up of 2 end shields, one which supports the motor shaft with the rotor and one which accommodates the stator.
- the end shields and housings are usually made of metal and / or a metal alloy.
- the end shields and housings are usually connected to each other by screwing. This type of construction solves the problem of keeping rotor and stator separate so that the drive is not affected by, for example, magnetic attraction or forces arising from the rotational movement, mass inertia, imbalance, etc.
- Power weight of the drive (power of the drive based on the weight) is a decisive criterion. To achieve a high power weight, the mass of the passive components (housing, end shields) must be kept as low as possible.
- the object of the present invention is therefore to provide a concept by means of which a housing for, for example, a drive shaft can be created in which the weight of the components, in particular of the end shields, is reduced.
- the object and object of the invention is therefore a housing for a drive shaft, wherein at least one element of the housing, the magnetic shield allows and / or metal or a metal alloy is wholly or partially replaced by an element made of a fiber reinforced plastic.
- the invention relates to a method for producing a housing for a drive shaft by fiber composite plastics processing technology.
- fiber composite plastics processing technology for example, winding technology, prepreg technology, laminating technology and liquid infusion technology are mentioned.
- the individual components (Ge) housing and / or end shields) in whole or in part.
- housing and end shield are integrated in a fiber-composite-like barrel construction (see FIG. 2).
- orientation of the fibers in the fiber-reinforced plastic is adapted to the weight distribution such that the highest weight lies in the direction of the fiber reinforcement.
- the fiber orientation of the fiber-reinforced plastic along the main load paths so that the housing is particularly thin and thus can be realized weight-saving.
- the embodiment of the invention in which a fiber-reinforced plastic is used, which has higher specific mechanical stiffnesses and / or strengths in the fiber direction than the common metals, metal alloys and / or metallic materials such as steel, aluminum, magnesium, etc.
- a fiber-reinforced plastic which has higher specific mechanical stiffnesses and / or strengths in the fiber direction than the common metals, metal alloys and / or metallic materials such as steel, aluminum, magnesium, etc.
- Fiber composite plastics based on carbon fibers are used with particular advantage because they exhibit a very high and therefore favorable stiffness or strength-to-weight ratio. Therefore, it is proposed to make these components from fiber composite materials such as carbon fiber reinforced plastic (CFRP), glass fiber reinforced plastic (GRP) and / or aramid fiber reinforced plastic (AFK), or combinations of these materials.
- CFRP carbon fiber reinforced plastic
- GRP glass fiber reinforced plastic
- AFK aramid fiber reinforced plastic
- Integral fiber composite construction In a particularly advantageous embodiment, the housing, including the end shield, is produced as a complete structure in a fiber-composite manner. This structure can be realized as a "barrel construction" ( Figure 2)
- riveting are in the inventive creation of a housing with end shield made of fiber reinforced plastic connecting methods, as are customary for the processing of fiber-reinforced plastics used.
- connection methods are for example bonding, looping and / or insert technique called.
- FIG. 1 shows the prior art
- FIG. 2 shows an embodiment of the invention, the preferred barrel construction
- Figure 1 shows the classic metallic construction 1 with housing, end shield and power parts with bolted components. To recognize the housing 2 with the shaft 3, the two end shields 4, with the housing 2 through
- FIG. 2 shows a fiber composite construction, in particular the variant in which housing and end shield are integrated, the "barrel housing" according to a preferred embodiment of the present invention is shown in FIG.
- the barrel housing 7 is constructed ellipsoidally and, for example, a carbon fiber plastic (CFRP) sheath with integrated end shield, for example in winding technology or prepreg technology.
- CFRP carbon fiber plastic
- mass-producible and cost-effective methods for example the already mentioned winding technology and prepreg technology, but also all types of laminating techniques, as well as liquid infusion technology can be used for the components of fiber reinforced, in particular made of long fiber reinforced plastic.
- This also makes it possible, for example, to produce in a continuous process and at low cost.
- the invention proposes for the first time the mechanical and / or constructive replacement of a classic housing and bearing plate construction for drive shafts. As stated, two directions are suggested, one being the targeted use of the anisotropic mechanical properties of the fiber reinforced plastic parts and the other the reduction of the mass of the passive parts. Thus, significantly increased performance weights can be achieved.
- the invention discloses a possibility to replace heavy metallic components of a housing for a drive shaft by lighter and optionally even more resilient fiber reinforced plastics.
