Abstract: In a turbodrill, there is no guarantee that a rotary friction ring (1) is or will remain exactly at right angles to its shaft (2). Wear against a co-operating non-rotary friction ring (6) is thus uneven, and if the surrounding medium is drilling mud, small abrasive grains can penetrate between the friction rings where they are not in contact and score them where they are in contact. The non-rotary friction ring is mounted on a moving sleeve (28) which is connected to a fixed sleeve (33). A spring (17) urges the friction rings into contact. An arrangement of balls in axial grooves between the sleeves allows the moving sleeve (28) to tilt slightly relative to the fixed sleeve (33). The non-rotary friction ring can thus wobble to keep in good contact with the rotary friction ring.

Abstract: A fixed pad thrust bearing for a turbomachine comprises a ring of sector-shaped pads separated by grooves and facing a thrust collar integral with the rotor of the turbomachine within a thrust bearing cage integral with the rotor. The ring bears on a deformable ring. Each pad is fed with oil via a space formed in the wall of the cage and facing an orifice in a bore in the pad. A front surface of each pad facing the collar is inclined relative to the rear surface of the ring. Each pad is further formed with a groove communicating with the aforementioned bore but not reaching as far as the inner and outer edges of the pad, being disposed adjacent the leading edge of the pad. The oil is recovered centrifugally from the outer edge of the collar. In this way, virtually all the power consumed by the oil goes towards providing the hydrodynamic supporting force, minimizing the shearing losses between the fixed and moving parts within the thrust bearing cage.
