The beneficial effect of this basic scheme lies in: by adopting the arrangement, the exhaust muffler is connected with the mounting bracket through the belt type hoop, and the belt type hoop has certain elasticity, so that the exhaust muffler is in non-rigid connection with the mounting bracket, thereby reducing vibration transmission between the exhaust muffler and the mounting bracket, further improving the stability and fatigue durability of the mounting bracket under the vibration effect, and enhancing the reliability of the exhaust muffler mounting assembly.
Further, the mounting bracket is provided with a first supporting plate vertical to the axial direction of the exhaust muffler and a second supporting plate parallel to the axial direction of the exhaust muffler, and connecting holes are formed in the first supporting plate and the second supporting plate. By adopting the arrangement, the first support plate and the second support plate are utilized to resist the actions in two directions perpendicular to each other, so that the structural stability of the mounting bracket is enhanced, and the reliability of the exhaust muffler mounting assembly is further improved.
Further, a bending part is arranged between the connecting hole and the connecting part on the first supporting plate. By adopting the arrangement, the toughness of the first supporting plate is improved by utilizing the bending part, so that the vibration resistance of the mounting bracket is further improved, and the reliability of the exhaust muffler mounting assembly is further enhanced.
Further, the exhaust muffler is connected with the exhaust elbow through a joint assembly, the joint assembly comprises a muffler joint connected to the exhaust muffler, an exhaust pipe outer sleeve and an exhaust pipe inner sleeve connected to the end part of the exhaust elbow, and a containing cavity for plugging the muffler joint is arranged between the exhaust pipe outer sleeve and the exhaust pipe inner sleeve. By adopting the arrangement, the connection between the new exhaust muffler and the exhaust elbow is realized through the plug-in fit of the muffler joint between the exhaust pipe outer sleeve and the exhaust pipe inner sleeve, so that the connection operation is simpler, the assembly tolerance between the exhaust elbow and the exhaust muffler can be effectively overcome, and the processing difficulty is reduced.
Further, the outer sleeve and the inner sleeve are respectively provided with a waveform part for interference fit with the muffler joint. By adopting the arrangement, the sealing effect between the outer sleeve and the inner sleeve of the exhaust pipe and the muffler joint is realized by utilizing the line contact and interference fit between the wavy part and the muffler joint, thereby enhancing the connection tightness.

Detailed Description
The following is a further detailed description of the embodiments:
reference numerals in the drawings of the specification include: the exhaust muffler 1, the anchor bolt 21, the steel belt 22, the first supporting plate 31, the second supporting plate 32, the connecting part 33, the bending part 311, the muffler joint 4, the exhaust pipe outer sleeve 5, the exhaust pipe inner sleeve 6 and the exhaust elbow 7.
An embodiment is substantially as shown in figures 2 to 4: an exhaust muffler installation assembly of an aeroengine comprises an exhaust muffler 1 and an exhaust elbow 7 communicated with the exhaust muffler 1, wherein an installation bracket is arranged on the exhaust muffler 1. In this embodiment, the mounting bracket is provided with a connection portion 33, and the connection portion 33 is attached to the exhaust muffler 1 through a band-type anchor ear. In this embodiment, the band type anchor ear is composed of a steel band 22 and anchor ear bolts 21 for adjusting the distance between both ends of the steel band 22. The mounting bracket is provided with a first supporting plate 31 perpendicular to the axial direction of the exhaust muffler 1 and a second supporting plate 32 parallel to the axial direction of the exhaust muffler 1, and connecting holes are formed in the first supporting plate 31 and the second supporting plate 32, so that the central lines of the two connecting holes are perpendicular to each other, and the mounting bracket can restrict the axial direction and the radial direction of the exhaust muffler 1. A bending portion 311 is disposed between the connecting hole and the connecting portion 33 on the first supporting plate 31, and in this embodiment, the bending portion 311 is disposed near the connecting hole on the first supporting plate 31.
In this embodiment, the exhaust muffler 1 and the exhaust elbow 7 are connected by a joint assembly. The joint assembly comprises a muffler joint 4 connected to the exhaust muffler 1, an exhaust pipe outer sleeve 5 and an exhaust pipe inner sleeve 6 connected to the end part of an exhaust elbow 7, and a containing cavity for plugging the muffler joint 4 is arranged between the exhaust pipe outer sleeve 5 and the exhaust pipe inner sleeve 6. The exhaust pipe outer sleeve 5 and the exhaust pipe inner sleeve 6 are provided with wave-shaped parts for interference fit with the muffler joint 4.
The specific implementation process is as follows:
when the exhaust muffler is used, the exhaust muffler 1 is connected with the mounting bracket through the belt type hoop, and then the mounting bracket is connected with the engine, so that the exhaust muffler 1 is fixed on the engine. Finally, the muffler joint 4 is inserted between the exhaust pipe outer sleeve 5 and the exhaust pipe inner sleeve 6, so that the exhaust muffler 1 is connected with the exhaust elbow 7.
