Abstract
Abstract A housing system for gas turbines, especially vehicle gas turbines, according to which in a main housing for a gas turbine there is detachably arranged a housing which includes a bell-shaped bearing housing section provided at its radially largest portion with a cast-on bearing wall, and a compressor housing section and a cover pertaining to the compressor housing section. This cover forms a partition between the compressor intake chamber and the transmission chamber in the bell-shaped bearing housing section. When viewing in the direction toward the bell-shaped bearing housing section, the cover is preceded by the compressor housing section, and the compressor housing section and the cover and the bearing housing section are successively and detachably connected to the main housing and coaxially guided and centered thereby.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
198 words
In combination in a gas generation housing system for gas turbines, especially vehicle gas turbines: main housing means for a gas turbine, a gas generator housing arranged at least partially in said main housing means and including an externally bell-shaped section forming a bearing housing and provided at the region of its greatest radial extension with a firmly cast on bearing wall, bearing means arranged in said bearing housing, shaft means rotatably journaled in said bearing means, a turbine wheel mounted at one end section of said shaft means for rotation therewith, a compressor wheel mounted at the other end section of said shaft means for rotation therewith, compressor housing means housing said compressor wheel and defining therewith a compressor suction chamber, said compressor housing means including a wall forming a detachable cover and together with said bearing housing defining a transmission chamber, said compressor housing means aside from said cover and said bearing housing means respectively forming individual sections successively and detachable connected to said main housing means, said main housing means including centering means for coaxially receiving and centering said individual sections, and means for detachably connecting all of said individual sections to said main housing.

In combination in a gas generation housing system for gas turbines, especially vehicle gas turbines: main housing means for a gas turbine, a gas generator housing arranged at least partially in said main housing means and including an externally bell-shaped section forming a bearing housing and provided at the region of its greatest radial extension with a firmly cast on bearing wall, bearing means arranged in said bearing housing, shaft means rotatably journaled in said bearing means, a turbine wheel mounted at one end section of said shaft means for rotation therewith, a compressor wheel mounted at the other end section of said shaft means for rotation therewith, compressor housing means housing said compressor wheel and defining therewith a compressor suction chamber, said compressor housing means including a wall forming a detachable cover and together with said bearing housing defining a transmission chamber, said compressor housing means aside from said cover and said bearing housing means respectively forming individual sections successively and detachable connected to said main housing means, said main housing means including centering means for coaxially receiving and centering said individual sections, and means for detachably connecting all of said individual sections to said main housing.
Claim 3
Dependent Claim
33 words
The combination of claim 1, in which all of said individual sections cover and compressor housing means have radially outer circular surfaces of nearly the same diameter for receiving by said centering means.
Claim 4
Dependent Claim
26 words
The combination according to claim 2, which includes radial seals located between said main housing means and the outer circular surfaces respectively of said individual sections.
Claim 5
Dependent Claim
42 words
The combination according to claim 3, in which said means for detachably connecting all of said individual sections to said main housing means include screws common to and extending through all of said individual sections and threadedly engaging said main housing means.
Claim 6
Dependent Claim
26 words
The combination according to claim 4, in which said turbine wheel and said compressor wheel are supported only by said bearing means in said bearing housing.
Claim 7
Dependent Claim
27 words
The combination according to claim 5, which includes additional support means mounted in said cast-on bearing wall, and transmission gear means journaled in said additional support means.
Claim 8
Dependent Claim
33 words
