Tilting pad bearing
A tilting pad bearing ( 10 ) including tilting pads ( 1, 2, 3 ) retained and positioned so that the tilting pads can tilt in a housing body ( 8 ) with a frame-type spring unit ( 8 ), such that, during operation of the tilting pad bearing ( 10 ), converging bearing gaps are created between the tilting pads ( 1,2,3 ) and a rotor body ( 4 ) that is rotatably mounted about an axis of rotation. In order to improve the functioning and/or manufacturing of the tilting pad bearing ( 10 ), the tilting pad bearing ( 10 ) includes rolling elements ( 6, 7 ) arranged between the housing body ( 5 ) and the tilting pads ( 1,2, 3 ).
1.

2. The tilting pad bearing as claimed in claim 1 , wherein the rolling elements ( 24 ; 44 ) are embodied as rollers.
3. The tilting pad bearing as claimed in claim 1 , wherein the rolling elements ( 6 , 6 ; 20 ) are embodied as balls.
4. The tilting pad bearing as claimed in claim 1 , wherein the cage ( 9 ) comprises at least one annular body ( 11 , 12 ; 31 , 32 ; 45 ).
5. The tilting pad bearing as claimed in claim 1 , wherein the tilting pads ( 1 , 2 , 3 ) are each assigned a respective spring element ( 13 , 14 , 15 ; 23 ; 27 ; 43 ) in order to position and hold a respective tilting pad ( 1 , 2 , 3 ) so that the respective tilting pad can tilt in the housing body ( 5 ).
6. The tilting pad bearing as claimed in claim 5 , wherein the respective spring element ( 13 , 14 , 15 ; 23 ; 27 ; 43 ) fits around the respective tilting pad ( 1 , 2 , 3 ) at ends which are opposite in a circumferential direction.
7. The tilting pad bearing as claimed in claim 6 , wherein the respective spring element ( 23 ; 43 ) comprises at least one spring tab ( 21 ; 25 ), which is biased inward against the respective tilting pad ( 1 ).
8. The tilting pad bearing as claimed in claim 5 , wherein the respective spring element ( 23 ; 43 ) comprises at least one spring tab ( 21 ; 25 ), which is biased inward against the respective tilting pad ( 1 ).
9. A tilting pad bearing ( 10 ) comprising tilting pads ( 1 , 2 , 3 ), which are positioned and held so that the tilting pads can tilt in a housing body ( 5 ) by a spring device ( 8 ) in order, during operation of the tilting pad bearing ( 10 ), to produce converging bearing gaps between the tilting pads ( 1 , 2 , 3 ) and a rotor body ( 4 ) mounted so as to be rotatable about an axis of rotation, wherein rolling elements ( 6 , 7 ; 20 ; 24 ; 44 ) are arranged between the housing body ( 5 ) and the tilting pads ( 1 , 2 , 3 ), wherein the tilting pads ( 1 , 2 , 3 ) are each assigned a respective spring element ( 13 , 14 , 15 ; 23 ; 27 ; 43 ) in order to position and hold a respective tilting pad ( 1 , 2 , 3 ) so that the respective tilting pad can tilt in the housing body ( 5 ), wherein the respective spring element ( 13 , 14 , 15 ; 23 ; 27 ; 43 ) fits around the respective tilting pad ( 1 , 2 , 3 ) at ends which are opposite in a circumferential direction.
10. The tilting pad bearing as claimed in claim 9 , wherein the respective spring element ( 23 ; 43 ) comprises at least one spring tab ( 21 ; 25 ), which is biased inward against the respective tilting pad ( 1 ).
11. A tilting pad bearing ( 10 ) comprising tilting pads ( 1 , 2 , 3 ), which are positioned and held so that the tilting pads can tilt in a housing body ( 5 ) by a spring device ( 8 ) in order, during operation of the tilting pad bearing ( 10 ), to produce converging bearing gaps between the tilting pads ( 1 , 2 , 3 ) and a rotor body ( 4 ) mounted so as to be rotatable about an axis of rotation, wherein rolling elements ( 6 , 7 ; 20 ; 24 ; 44 ) are arranged between the housing body ( 5 ) and the tilting pads ( 1 , 2 , 3 ), wherein the tilting pads ( 1 , 2 , 3 ) are each assigned a respective spring element ( 13 , 14 , 15 ; 23 ; 27 ; 43 ) in order to position and hold a respective tilting pad ( 1 , 2 , 3 ) so that the respective tilting pad can tilt in the housing body ( 5 ), wherein the respective spring element ( 23 ; 43 ) comprises at least one spring tab ( 21 ; 25 ), which is biased inward against the respective tilting pad ( 1 ).
