Problems solved by technology

[0003] Most of the disc-shaft connection in the prior art adopts the structural form of flange and bolt connection. Although this structural form is easy to process, in order to reliably center the flange, it is necessary to design a large interference between the disc and the shaft. Therefore, Makes it difficult to disassemble
In addition, the disk shaft connection in the prior art is often in an unstable state after working for a long time

Embodiment Construction

[0064] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0065] The disk-shaft connection structure of the embodiment of the present invention is used to connect the disk and the shaft. For example, in one embodiment, the shaft may be a turbine shaft of an aero-engine, and the disk may be a turbine disk of an aero-engine. Of course, the present invention does not limit the types of the disk and the shaft. In other embodiments, the disk and the shaft may also be other components in o...

Abstract

An embodiment of the present invention provides a disk-shaft connection structure, including a shaft assembly, a disk assembly, a connecting piece, and a first locking piece. The shaft assembly is provided with a first flange portion, and the first flange portion includes a first positioning surface and a The second positioning surface opposite to the first positioning surface, the first positioning surface and the second positioning surface are arranged at intervals along the radial direction; the disk assembly is sleeved outside the shaft assembly, the disk assembly includes a second flange part, the second flange The part has a third positioning surface; the connecting piece is connected to the shaft assembly and the disc assembly, the connecting piece includes a body part and a third flange part, the third flange part is connected to the body part, the body part has a fourth positioning surface, and the first method The flange part, the second flange part and the third flange part are arranged correspondingly; the first locking part is locked on the first flange part, the second flange part and the third flange part, so that the third positioning surface and The first positioning surface is positioned relative to the second positioning surface, and the fourth positioning surface is positioned relative to the second positioning surface.

Description

technical field [0001] The present invention generally relates to the technical field of aero-engines, and in particular, relates to a disk-shaft connection structure. Background technique [0002] The disk-shaft connection is an important structural form in the rotor structure system, which is related to whether the rotor is stable and reliable during the working process. [0003] Most of the disc-shaft connection in the prior art adopts the structural form of flange and bolt connection. Although this structural form is easy to process, in order to reliably center the flange, it is necessary to design a large interference between the disc and the shaft. Therefore, This makes disassembly and assembly more difficult. In addition, the disk shaft connection in the prior art is often in an unstable state after working for a long time Contents of the invention [0004] The connection structure of the disk shaft in the embodiment of the present invention has the advantages of ...
