Problems solved by technology

[0003] However, the known shaft-hub connection structures cannot combine the characteristics of small installation space, high force and torque transmission, and high strength
For example, although the spline connection has a high torque transmission, it is not suitable for transmitting axial forces; for this purpose, an additional axial safety must be provided, which requires additional installation space

Embodiment Construction

[0037] figure 1 Shown are the shaft 10 , the hub 20 of the rotor wheel and the filler material 30 , which are joined to form the shaft-hub connection 1 in the assembled state. figure 1 The state of the two components, shaft 10 and hub 20 and filler material 30 , is shown here before joining to form shaft-hub connection 1 . According to the invention, the filler material 30 is strongly deformed or plasticized during the joining process of the shaft-hub connection 1 , so that a positive connection is formed. As a result, very high forces and moments can be transmitted, for example higher than in the case of conventional press or tooth or wedge connections.

[0038] exist figure 1 In the preferred embodiment, the filler material 30 is strongly deformed during engagement of the shaft-hub connection 1 , optionally under intense heating of the filler material 30 . For this purpose, the filler material 30 can also be configured in the form of a ring or as a hollow cylinder, for ex...

Abstract

The invention relates to a shaft-hub connection (1), particularly for mounting a rotor wheel on a shaft (10). The shaft-hub connection (1) comprises a shaft (10), a hub (20) and a filler material (30). The shaft (10) comprises an end section (11) on one end. A receiving region (21) is arranged in the hub (20). The end section (11) is arranged in the receiving region (21), with an intermediate layer of the filler material (30) positioned inbetween. The filler material (30) forms undercuts in the axial and rotational direction, in relation to the end section (11) and in relation to the receivingregion (21), so as to create a positive embodiment of the shaft-hub connection (1).

Description

technical field [0001] The invention relates to a shaft-hub connection, in particular for connecting a rotor wheel to a shaft. Background technique [0002] Shaft-hub connections are known in various embodiments from the prior art, for example from the textbook "Roloff / Matek Maschinenelemente: Normung, Berechnung, Gestaltung" (published by Vieweg+TeubnerVerlag). [0003] However, the known shaft-hub connections cannot combine the properties of small installation space, high force and torque transmission, and high strength. For example, splined connections, although having a high torque transmission, are not suitable for transmitting axial forces; for this purpose, additional axial securing must be provided, which in turn requires additional installation space. Contents of the invention [0004] On the other hand, the shaft-hub connection according to the invention has a high force and torque transmission and a high strength with only small structural dimensions. [0005]...
