Gearbox component with laminated fiber mat

Abstract

The invention relates to a component (101, 201) for transmitting or supporting at least one torque flow running from a drive shaft to an output shaft of the transmission; wherein a base body (103, 201) of the component is made of metal. The component has one or more fiber mats (105) laminated onto the base body (103, 201).

Description

[0001] The invention relates to a component according to the preamble of claim 1 and the use of such a component according to the preamble of claim 5.

[0002] Wind turbine gearboxes with a solar shaft made of a fiber composite material are known from the prior art. Such a solar shaft is disclosed in German patent application DE 10 2019 209 056 A1.

[0003] The invention is based on the objective of improving a component of a transmission subjected to a torque compared to the prior art. This objective is achieved by a component according to claim 1 and a use according to claim 5.

[0004] The component according to the invention is designed to transmit or support a torque flow running from a drive shaft to an output shaft of a gearbox. The component is, for example, a part of a gearbox housing or a shaft, such as a solar shaft.

[0005] The component has a round body. As with conventional gearbox components, this is made of metal, preferably steel.

[0006] According to the invention, the component comprises, in addition to the base body, one or more fiber mats laminated onto the base body. A fiber mat is a woven structure consisting of fibers. In particular, carbon or glass fiber mats are used as fiber mats for the component according to the invention.

[0007] Laminating refers to the creation of a material-bonded connection using an adhesive. Matrices used for conventional fiber-reinforced composites, for example, can be used as adhesives.

[0008] The stiffness and damping properties of the component are improved by the one or more fiber mats laminated on according to the invention.

[0009] In a preferred embodiment, the component is designed as a housing part. In particular, it can be a rotationally symmetrical housing part which, for example, can be screwed or bolted to a ring gear on one or both end faces.

[0010] In an alternative preferred embodiment, the component is designed as a wave, preferably as a solar wave.

[0011] Fiber-reinforced composites have not yet been widely adopted in wind turbine gearboxes due to their uncertain long-term durability. However, the use of a [missing information] base body allows for an accurate and reliable prediction of long-term durability based on the extensive experience gained in the past with the use of metallic gearbox components. At the same time, the component according to the invention benefits from the advantages of a fiber-reinforced composite material. This makes the invention, contrary to the expectations of experts, suitable for further development as part of a wind turbine gearbox.

[0012] The above-described, for the transmission or support of at least one torque flow running from a drive shaft to an output shaft of the gearbox, is used according to the invention to reduce vibrations resulting from the transmission and / or support of the torque flow.

[0013] Preferred embodiments of the invention are illustrated in the figures. Matching reference numerals denote identical or functionally equivalent features. Specifically, the figures show: Fig. 1 a housing component; and Fig. 2 a solar wave.

[0014] The in Fig. The housing component 101 shown comprises a housing shell 103 and a fiber mat 105. The fiber mat 105 is laminated onto the housing shell 103.

[0015] According to Fig. In Figure 2, the fiber mat 105 is laminated onto a solar shaft 201. The solar shaft 201 is integrally connected to a sun wheel 203. The fiber mat 105 has a cylindrical shape and covers part of the outer surface of the solar shaft 201.
