1. 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), the tilting pad bearing (10) further including a cage (9) which serves to hold the rolling elements (6, 7; 20) in position between the housing body (5) and the tilting pads (1, 2, 3), wherein the cage (9) has through-holes (19; 26; 51-52) in which the rolling elements (6, 7; 20; 24; 44) are accommodated with play in such a way that the rolling elements (6, 7; 20; 24; 44) have rolling contact both with the housing body (5) and with a respective tilting pad (1, 2, 3) outside the through-holes (19; 26; 51-52).
 
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.
 
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).
