Title:
METHOD FOR MANUFACTURING TURBIBE HOUSING
Document Type and Number:
WIPO Patent Application WO/2019/130879
Kind Code:
A1
Abstract:
In an inner cylinder assembling step, an inner cylinder (20) which forms a spiral exhaust gas flow passage (K) is assembled by connecting sheet metal inner cylinder segments (21, 22) and a cast inner cylinder segment (23). In a center flange connecting step, the sheet metal inner cylinder segments (21, 22) are connected to a center flange (11) which receives the drive shaft (14a) of a turbine wheel (14). In an outer cylinder connecting step, an outer cylinder (40) for covering the inner cylinder (20) is connected to an exhaust gas inlet-side flange (12) which is to be an exhaust gas inlet leading to the inner cylinder (20), and is also connected to the center flange (11). In a masking step, the portion where the sheet metal inner cylinder segments (21, 22) and the cast inner cylinder segment (23) are connected, and/or the opening between the outer cylinder (40) and the inner cylinder (20) is closed. In a cutting step, the inner wall surface of the cast inner cylinder segment (23), which faces the turbine wheel (14), is cut after the masking step.
