TURBINE CASING, TURBINE RUNNING ON EXHAUST GASES (VERSIONS) AND TURBO SUPERCHARGER INCORPORATING ABOVE-SAID TURBINE (VERSIONS) Russian patent published in 2008 - IPC F01D25/24 

FIELD: engines and pumps.

SUBSTANCE: turbine casing incorporates a bearing housing to accommodate a shaft to run therein, a gas intake casing resting upon the said bearing housing and enveloping it concentrically on the bearing surface part and a centering ring to align the gas intake casing relative to aforesaid shaft fitted in the bearing housing. The said centering ring and either the bearing housing or the gas intake casing comprises centering elements fitted one into the other and furnished with recesses and either radially or axially aligned centering ledges to be fitted into the said recesses. There is a force-closure joint arranged between the casing comprising no centering elements, that is, either between the gas intake casing or the bearing housing and the centering ring. In compliance with the other inventions of the propose set, proposed is the turbine incorporating a turbine casing arranged as-indicated above, but with gas intake casing and the bearing housing are aligned relative to the shaft and can be inter-jointed at whatever angles to each other. The invention describes a proposed turbo supercharger incorporating the aforesaid turbine.

EFFECT: invention allows reliable centering of gas intake casing relative to bearing housing and whatever angular position of said casing relative to bearing housing.
