Problems solved by technology

The base body of the casing in the above two methods may reduce the strength and shorten the life of the casing due to welding deformation. This situation will be very unfavorable to the casing as an important part.
[0003] In view of the above-mentioned technical problems existing in the prior art, no effective solution has been proposed that can not only ensure the strength of the casing, but also facilitate and quickly install the object and effectively prevent damage to the mounting thread

Embodiment Construction

[0020] It should be noted that the features in the various embodiments of the present invention may be combined with each other in the absence of explicit limitation or conflict. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] figure 1 It is a schematic structural view of a casing in the prior art, in which a part of the casing base 200 is shown, and the mounting seat 100 tapped with through-hole mounting threads has a shape similar to a parallelogram (or waist shape) from a top view. On the upper surface of the casing base 200 (namely at A), the mounting base 100 and the casing base 200 are connected together by welding to form a casing.

[0022] figure 2 It is a structural schematic diagram of another casing in the prior art, wherein a part of casing base 201 is shown, and the mounting base 101 tapped with mounting threads has a quadrangular upper surface from a top view, in which On the outer sur...

Abstract

The invention relates to an engine case, comprising an engine case base body and an installation seat, and further comprising an installation column body, wherein the installation column body is raised outwards from the outer surface of the engine case base body and is provided with a through hole, and the installation seat is fixedly arranged at one end of the installation column body, which is away from the engine case base body. According to the technical scheme provided by the invention, the installation column body is raised outwards from the outer surface of the engine case base body, so that the welding deformation generated if the installation column body is welded on the engine case base body can be avoided, thus enhancing the strength of the engine case and prolonging the service life of the engine case.

Description

technical field [0001] The invention relates to a casing. Background technique [0002] As an important component of a gas turbine engine, the casing not only bears aerodynamic, vibration and other loads, but also has a very complex structure. There are various mounting seats on it, such as nozzle mounting seats, electric nozzle mounting seats, air induction pipe mounting seats and measuring mount etc. In the past, the connections between these mounts and the casing base were figure 1 or figure 2 The structural style shown. figure 1 , at the edge of the casing base 200 (namely at A), the mount 100 and the casing base 200 are welded together; figure 2 , on the outer surface of the case base 201 (ie at B), the mount 101 and the case base 201 are welded together. The casing base in the above two methods may reduce the strength and shorten the life of the casing due to welding deformation, which will be very unfavorable for the casing as an important part. [0003] Aimin...
