Inventor: KONISHI MOTOKI
IPC: F01D25/24
Filed: 2020-02-27
Abstract: To prevent the damage and a crack of a tongue part, in a turbine housing of an exhaust turbo supercharger.SOLUTION: A turbine housing 1 comprises a turbine scroll chamber 9, and a region sandwiched by the turbine scroll circumferential 9 and an exhaust gas introduction passage 8 out of the turbine housing 1 serves as a tongue part 38 whose thickness is thinned toward a tip 38e. An inner face 38b of the tongue part 38 is applied with hardening processing by shot-peening which is performed by injecting small ball groups from an exhaust gas outlet passage 10 side. Since the inner face 38b is densified, the tongue part 38 is suppressed in a spread of thermal stress to a core part, and can prevent the generation of a crack 39. Also, since a direction F1 of the thermal stress and a direction F2 of residual stress which is generated by the processing hardening by the shot-peening become substantially reverse with respect to each other, the stress is canceled, and the generation of the crack 39 can be prevented.SELECTED DRAWING: Figure 8
