A rotating, conductive, heat transfer device includes an outer race (14) having an axis (12), an inner race (16) coaxial with the outer race, and a plurality of bearing balls (18 to 38) disposed in a radial direction between the inner race and the outer race. The device (10) also includes a plurality of separators (40 to 58) disposed alternately in a peripheral direction between the bearing balls. A first track (62) and a second track (66) are supported by the inner race (16), for supporting the separators. The inner race has a first, fixed, inner ring portion (92) with a first bearing surface (96), and has a second, separable, inner ring portion (94) with a second bearing surface (98). The outer race (14) has a third bearing surface (100), disposed in a radial direction opposite to the first bearing surface (96) and also has a fourth bearing surface (102), disposed in a radial direction opposite to the second bearing surface (98). The first and second and third and fourth bearing surfaces are in contact with a spherical surface of each bearing ball. A plurality of coil springs (110 to 122) urge the second inner ring portion (92) in an axial direction toward the first inner ring portion (92), thereby applying first and second and third and fourth forces normal to the respective first and second and thrid and fourth bearing surfaces, for providing heat conduction from one race to the other race. |
