COMPRESSOR COVER ASSEMBLY METHOD AND FORMING TOOL

摘要

A method of assembling and retaining a noise attenuation device (30) within an air inlet (16) of a compressor cover (12) includes inserting the noise attenuation device (30) into the air inlet (16) and applying a rolling compressive force to the air inlet (16) using a forming tool (40). As a result, the air inlet terminal end (17) is deformed radially inward so as to form a radially-inwardly protruding lip (17b) about the air inlet terminal end (17). The radially-inwardly protruding lip (17b) is configured to retain the noise attenuation device (30) within the air inlet (16). The forming tool (40) used to form the radially-inwardly protruding lip (17b) is also described.

1. A method of assembling a compressor cover assembly (24) using a forming tool (40) in which the compressor cover assembly (24) includes a compressor cover (12) and a noise attenuation device (30), the method comprising
inserting the noise attenuation device (30) into an air inlet (16) of the compressor cover (12); moving at least one of the compressor cover (12) and the forming tool (40) toward each other to an extent that the forming tool (40) applies a deforming compressive force to the air inlet (16); and while the forming tool (40) applies the deforming compressive force to the air inlet (16), rotating at least one of the forming tool (40) and the compressor cover (12) such that the forming tool (40) deforms the air inlet (16) along a path defined by the intersection of the forming tool (40) and the air inlet (16), wherein a deformation of the air inlet (16) resulting from the steps of moving and rotating serves to retain the noise attenuation device (30) in the air inlet (16).
