Abstract
Abstract The blades of the vane ring are supported in an axle housing which is fixed to the outside of the blade carrier. Each housing includes a spaced inner wall and outer wall which define a coolant chamber therebetween. The inner wall also terminates short of the outer wall to form an open-ended chamber for reducing the flow of heat from the working medium within the blade carrier.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
101 words
In combination, a vane ring having a blade carrier and a plurality of blades passing therethrough, each said blade having an axle journal extending outwardly through said blade carrier to the outside thereof; and a separate bearing mount for each blade radially removable therefrom, each bearing mount having an axle housing fixed to said blade carrier on the outside thereof, said axle housing rotatably supporting said axle journal therein with respect to said blade carrier, and including means for removably mounting each said bearing mount individually on a respective blade whereby each said bearing mount can be removed from said carrier.
Claim 2
Dependent Claim
101 words
In combination, a vane ring having a blade carrier and a plurality of blades passing therethrough, each said blade having an axle journal extending outwardly through said blade carrier to the outside thereof; and a separate bearing mount for each blade radially removable therefrom, each bearing mount having an axle housing fixed to said blade carrier on the outside thereof, said axle housing rotatably supporting said axle journal therein with respect to said blade carrier, and including means for removably mounting each said bearing mount individually on a respective blade whereby each said bearing mount can be removed from said carrier.
Claim 3
Dependent Claim
101 words
In combination, a vane ring having a blade carrier and a plurality of blades passing therethrough, each said blade having an axle journal extending outwardly through said blade carrier to the outside thereof; and a bearing mount having an axle housing fixed to said blade carrier on the outside thereof, said axle housing rotatably supporting said axle journal therein with respect to said blade carrier and including an inner tubelike wall and an outer wall defining the exterior of said housing and which further includes at least one bearing mounted on said inner wall in supporting relation to said axle journal.
Claim 4
Dependent Claim
101 words
In combination, a vane ring having a blade carrier and a plurality of blades passing therethrough, each said blade having an axle journal extending outwardly through said blade carrier to the outside thereof; and a bearing mount having an axle housing fixed to said blade carrier on the outside thereof, said axle housing rotatably supporting said axle journal therein with respect to said blade carrier and including an inner tubelike wall and an outer wall defining the exterior of said housing and which further includes at least one bearing mounted on said inner wall in supporting relation to said axle journal.
Claim 5
Dependent Claim
68 words
The combination as set forth in claim 2 wherein said axle housing further includes at least two annular supports supporting said inner wall on said outer wall in spaced relation to define a closed hollow space therebetween, said annular support closest said blade carrier being spaced inwardly of the adjacent ends of said inner and outer walls to define an open-ended hollow space therebetween facing said blade carrier.
Claim 6
Dependent Claim
34 words
The combination as set forth in claim 3 further comprising a distribution line connected to each said closed hollow space of at least one group of axle housings for introduction of a coolant thereinto.
Claim 7
Dependent Claim
26 words
The combination as set forth in claim 4 further comprising a pipe section interconnected to said closed hollow spaces of each pair of adjoining axle housings.
Claim 8
Dependent Claim
40 words
The combination as set forth in claim 4 wherein said annular support closest said blade carrier includes a plurality of bores communicating said closed hollow space and said open-ended hollow space with each other for the flow of coolant therebetween.
Claim 9
Dependent Claim
27 words
The combination as set forth in claim 2 wherein said inner wall mounts a bearing sleeve at each end thereof in supporting relation to said axle journal.
Claim 10
Dependent Claim
28 words
The combination as set forth in claim 7 wherein each bearing sleeve is made of a heat resistant plastic material characterized in being free of a lubricant supply.
Claim 11
Dependent Claim
30 words
The combination as set forth in claim 2 further comprising a seal between said axle housing and said axle journal on the side of said bearing opposite said blade carrier.
Claim 12
Dependent Claim
24 words
The combination as set forth in claim 2 wherein said outer wall is mounted on said blade carrier to support said axle housing thereon.
Claim 13
Dependent Claim
30 words
The combination as set forth in claim 2 wherein said inner wall terminates at the end closest said blade carrier at a point within the plane of said outer wall.
Claim 14
Dependent Claim
71 words
The combination as set forth in claim 2 wherein said inner and outer wall define an open-ended hollow space therebetween facing said blade carrier and which further comprises a displacement body in said hollow space forming a flat narrow passage along the surfaces thereof opposite each of said inner and outer walls and means for introducing a flow of coolant into said hollow space to flow through said flat narrow passages.
Claim 15
Dependent Claim
17 words
The combination as set forth in claim 12 wherein said displacement body is made of sheet metal.
Claim 16
Dependent Claim
64 words
The combination as set forth in claim 13 wherein said displacement body is of U-shaped cross section, the outer leg of said body being of greater length than the inner leg and being supported on said blade carrIer, said outer leg including bores adjacent the end thereof communicating opposite sides of said leg with each other for a flow of coolant towards said blade.
Claim 17
Dependent Claim
85 words
In combination, a vane ring having a blade carrier and a plurality of blades passing therethrough, each said blade having an axle journal extending outwardly through said blade carrier to the outside thereof; and a bearing mount having an axle housing fixed to said blade carrier on the outside thereof, said axle housing rotatably supporting said axle journal therein with respect to said blade carrier and including a peripheral flange spaced from said blade carrier for mounting of said axle housing on said blade carrier.
Claim 18
Dependent Claim
85 words
In combination, a vane ring having a blade carrier and a plurality of blades passing therethrough, each said blade having an axle journal extending outwardly through said blade carrier to the outside thereof; and a bearing mount having an axle housing fixed to said blade carrier on the outside thereof, said axle housing rotatably supporting said axle journal therein with respect to said blade carrier and including a peripheral flange spaced from said blade carrier for mounting of said axle housing on said blade carrier.
Claim 19
Dependent Claim
26 words
The combination as set forth in claim 1 wherein said axle housing further includes means for conducting a coolant therethrough for cooling said axle journal therein.
