FIELD: engines and pumps. ^ SUBSTANCE: turbine running on waste gases incorporates a turbine casing, a shaft running in the casing bearings, a turbine wheel fitted on the shaft and a thermal protective wall. The aforesaid wall constricts, along with the turbine casing, the turbine wheel blasting channel and incorporates two outward supports, the first of them being designed to rest on the bearing housing, the second one on the turbine casing. In compliance with the first version at least one support represents peripheral edges designed to rest on the bearing housing and/or the turbine casing peripheral edges. In compliance with the other version, the thermal protective wall has in the area of the first or the second support the centering cams entering the radial grooves arranged in the bearing housing or the turbine casing. In compliance with the third version the said thermal protective wall incorporates in the area of the first or the second support the grooves receiving the aforesaid centering cams arranged on the bearing housing or the turbine casing. The other inventions of the proposed set relate to the thermal protective wall, the bearing housing and the turbine casing to be used in aforesaid turbine running on waste gases. ^ EFFECT: simple and reliable turbine casing centering relative to shaft running in bearing with extra components. ^ 9 cl, 6 dwg |
