Title:

METHOD FOR MANUFACTURING SUPERCHARGER COMPRESSOR HOUSING, AND SUPERCHARGER COMPRESSOR HOUSING

Document Type and Number:

WIPO Patent Application WO/2018/220713

Kind Code:

A1

Abstract:

When a compressor housing with an abradable seal is manufactured, the housing can be manufactured by manufacturing equipment simpler than a thermal spraying device, an injection molding device, etc., and between the abradable seal and a groove part provided to a main-body side of the compressor housing, a protruding part having greater length along the axial direction of the groove can be formed by deforming a portion of the abradable seal. This invention provides: a method for manufacturing a supercharger compressor housing, in which a supercharger compressor housing is manufactured through at least a local heating step for locally heating an area to be heated HT, which is part of an abradable seal 10, and a mounting/fixing step for mounting and fixing the abradable seal 10 to a mounting/fixing surface 140 of a compressor housing main body 100, the locally heated area to be heated HT being inserted while being deformed into groove parts 140 provided to the mounting/fixing surface 140 in the mounting/fixing step; and a compressor housing created using this manufacturing method.
