Vibration absorbing structure for thin-wall support of auxiliary plate of shaft part and vibration absorbing method thereof

Abstract

The invention discloses a vibration absorbing structure for a thin-wall support of an auxiliary plate of a shaft part and a vibration absorbing method thereof. The vibration absorbing structure comprises rubber rings which are arranged at two sides of the auxiliary plate of the part, wherein bakelite plates cover the outer sides of the rubber rings; the rubber rings and the bakelite plates are correspondingly fixed to two sides of the auxiliary plate through fasteners and can be fixed to the auxiliary plate by bolts which correspondingly pass through mounting holes in the rubber rings and the bakelite plates. The method is characterized in that the mounting holes in the manufactured bakelite plate and the rubber ring at one side of the part are aligned, then the bakelite plate and the rubber ring are positioned on the part, and the mounting holes are aligned to through holes in the auxiliary plate; the processed mounting holes in the bakelite plate and the rubber ring at the other side of the part are aligned, and then the bakelite plate and the rubber ring are positioned to the part; the bakelite plates and the rubber rings are locked through the through holes in the auxiliary plate, so as to achieve the auxiliary supporting effect. The vibration absorbing structure and the vibration absorbing method are applicable to the processing of sealing teeth and threads in thin-wall supporting parts of various shaft parts of aircraft engines, and the vibration caused by poor support stiffness in the processing process can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of thin-wall support structure processing of aero-engine shaft parts, and in particular relates to a thin-wall support shock-absorbing structure of an auxiliary plate of shaft parts and a method thereof. Background technique [0002] In the aviation industry, with the improvement of design and manufacturing capabilities, the integration of engine parts is getting higher and higher, the design of parts tends to be integrated, lightweight, and precise, and the surface structure is becoming more and more complex. The structure of a certain type of shaft workpiece tends to be complex curved surfaces such as thin walls and multi-space profiles. Due to the limitation of processing equipment for shaft parts, special large horizontal lathes are used. Since the part belongs to the slender shaft type, the rigidity of the body structure is poor, and many uncertain factors such as axial bending deformation, dimensional...

AI Technical Summary

Problems solved by technology

At the same time, when the sealing teeth are processed in the process, because they are slender shaft parts, their rigidity is poor, and the parts are easy to deform with the change of cutting temperature during processing.

When processing the outer seal with tight teeth, the support wall of the part is very thin, which is very easy to cause residual vibration and damage the tool, making the surface finish unqualified and the size easily out of tolerance
