Patent Application
20180135701
This application claims priority to German patent application no. 10 2016 222 600.2 filed on Nov. 16, 2016, the contents of which are fully incorporated herein by reference.
The present disclosure is directed to an improved structure for a bearing carrier or bearing housing or part of a bearing housing.
A bearing housing made of a short-glass-fiber-reinforced polyamide is known. The relevant fibers are not targeted and are distributed randomly. In addition, bearing housings made of steel are known.
Furthermore, bearing carriers made of steel are known which are very heavy. These can corrode, and, due to their wall thickness, must be manufactured on relatively expensive large-format presses and using punching tools that are also expensive. Because of the investment costs of the presses and the punching tools, the manufacturing of the respective bearing carriers is only worthwhile for relatively high quantities.
One aspect of the disclosure comprises, in particular, achieving a high efficiency.
The disclosure is directed to a bearing carrier, or bearing housing, or part of a bearing housing.
According to the disclosure, at least one organic sheet and/or at least one pre-preg is provided. A high efficiency can thereby be achieved. In particular, a targeted introduction of oriented continuous fibers can be achieved, whereby an improved force-supporting and thus a low susceptibility to creep can be achieved, in particular in comparison to short-fiber reinforced polyamide components. In particular a low weight can be achieved. Furthermore, in particular it can be achieved that even small batch sizes are cost-effectively manufacturable. In particular, the use of expensive large-format presses can be avoided. In particular, the organic sheet can be a fabric, made of reinforcing fibers, impregnated with thermoplastic powder, or unidirectional bands, made of reinforcing fibers, impregnated with thermoplastic, wherein the reinforcing fibers can in particular be carbon- and/or glass- and/or aramid fibers. The pre-preg can in particular be a fabric, made of reinforcing fibers, impregnated with partially cured duroplastic resin, or unidirectional bands, made of reinforcing fibers, impregnated with partially hardened duroplastic resin, wherein the reinforcing fibers can in particular be carbon- and/or glass- and/or aramid fibers. Furthermore, in particular an additional corrosion protection can be omitted.
Furthermore, a method is disclosed for manufacturing a bearing carrier and/or a bearing housing and/or a part of a bearing housing, wherein two layers are attached to each other. Accordingly a high efficiency can be achieved.
Further advantages arise from the following description of the drawings. Exemplary embodiments of the disclosure are depicted in the drawings. The drawings, the description, and the claims contain numerous features in combination. The person skilled in the art will also advantageously consider the features individually and combine them into further meaningful combinations.
The bearing carrier includes a layering 16 that is comprised of a plurality of layers (
In other exemplary embodiments the layering can also additionally include one or more steel plates. The various layers occurring in the bearing carrier can be chosen according to the application for which the bearing carrier is to be used such that the bearing carrier has the desired stability and stiffness. In principle, however, in the layering all possible sequences of layers, selected in particular from the materials organic sheet, pre-preg, aluminum plate, and steel plate, are conceivable.
The bearing installed can be a rolling-element bearing or a sliding bearing.
In a method for manufacturing the bearing carrier, the circumferential contour and the bore of individual layers of the layering are cut-out using a laser or another automatic cutting tool. Thereafter the layers 18, 20 are attached to each other, wherein the layers 18, 20 are heated and pressed together. Subsequently the further layers of the layering are individually added, i.e., attached, by heating and pressing. Alternatively it is possible that all layers of the layering are correctly positioned relative to one another, heated, and subsequently pressed together so that a final shape of the bearing carrier arises. An adhesive can optionally be used for the attaching of the layers to one another. The bearing carrier manufactured in this way is now still machinable by drilling or milling.
During manufacturing the bearing is either pressed-in into the individual layers during the pressing of the individual layers, or pressed-in into the bore of the bearing carrier after the manufacturing of the bearing carrier.
An alternative exemplary embodiment is depicted in
A manufacturing of the bearing housing and the unit made of housing and bearing is effected in the same steps as the manufacturing of the bearing carrier or of the bearing carrier with the bearing; see exemplary embodiment of Figures one and two.
Representative, non-limiting examples of the present invention were described above in detail with reference to the attached drawings. This detailed description is merely intended to teach a person of skill in the art further details for practicing preferred aspects of the present teachings and is not intended to limit the scope of the invention. Furthermore, each of the additional features and teachings disclosed above may be utilized separately or in conjunction with other features and teachings to provide improved bearing carrier or bearing housing or part of a bearing housing.
Moreover, combinations of features and steps disclosed in the above detailed description may not be necessary to practice the invention in the broadest sense, and are instead taught merely to particularly describe representative examples of the invention. Furthermore, various features of the above-described representative examples, as well as the various independent and dependent claims below, may be combined in ways that are not specifically and explicitly enumerated in order to provide additional useful embodiments of the present teachings.
All features disclosed in the description and/or the claims are intended to be disclosed separately and independently from each other for the purpose of original written disclosure, as well as for the purpose of restricting the claimed subject matter, independent of the compositions of the features in the embodiments and/or the claims. In addition, all value ranges or indications of groups of entities are intended to disclose every possible intermediate value or intermediate entity for the purpose of original written disclosure, as well as for the purpose of restricting the claimed subject matter.
