Title: A gas-driven turbine, and a rotating mirror camera incorporating such a turbine
IPC: F01D25/16
Filed: 1961-06-14
Abstract: 973,123. Bearings. BECKMAN & WHITLEY Inc. June 14,1961 [June 17, 1960], No. 21456/61. Heading F2A. [Also in Division G2] A gas-driven turbine having a rotor shaft which extends through a lubricated bearing and a wall into a chamber from which lubricant must be excluded is provided with a conduit which opens on to the periphery of the rotor shaft between the bearing and the wall and is connect able to a sub-atmospheric pressure source whereby lubricant is sucked away from the shaft and gas is sucked out of the mirror chamber through the wall in counterflow to lubricant tending to move along the shaft, into the mirror chamber. As shown, the rotating mirror 72 of a high-speed photographic camera located in an evacuated chamber 18 is attached to the turbine rotor shaft 24 supported at one end by two bearings 38, 56 on opposite sides of the turbine, which is fed at 46 with high-pressure air, and at the other by three bearing wheels having plastic tyres spaced from each other by 120 degrees. The turbine rotor includes two annular rows of blades 114 separated by an annular groove 113 and the inside of the turbine stator has a groove 112 opposite the rotor groove denning a gas inlet passage which decreases in cross-sectional area between the inlet and outlet ends. Part of the high-pressure air is bled off along a pipe 122 to a lubricant reservoir 82 so that lubricant is delivered via a radial passage 134 into the end of the shaft 24 and is distributed via radial slots 178, 144 to the bearings 38, 56 thus forming oil seals on opposite sides of the turbine. Excess oil fed to the bearing 38 is returned to the reservoir at 160 by the centrifugal pump action of the vanes 154. Oil which travels along the shaft towards the mirror is thrown off along a disc 30 into a frustoconical depression 28 in a mechanical seal 22 and is drawn off by vacuum line 26 whilst leakage past the member 22 is prevented by air from the mirror chamber compressed by the peripheral parts of the rotating mirror travelling along radial passages 204 in the member 22 to the shaft 24. The bearing arrangement shown for the end of the mirror shaft remote from the turbine is suitable for speeds of 3000 r.p.s. but for speeds of 5000 r.p.s. it is preferable to employ bearing wheels larger than can be accommodated by such a configuration, and for this purpose two pairs of bearing roller wheels are disposed in spaced parallel planes with the lines of centres of each pair crossing at 90 degrees on the shaft axis. For speeds below 3000 r.p.s. the bearing element 56 may be omitted while retaining the centrifugal pump system for distributing lubricant to the bearing 38. A spring-loaded knob 68 may be pressed inwardly to turn the mirror shaft manually.
