Abstract

Air under pressure passes through rotatable hollow shaft 1 into stationary bearing enclosure 2 and through perforated plate 3 to support tape 4. Reaction motor 5 and counterweight 6 are mounted on the shaft. The weight of the latter is chosen to counterbalance the force of the motor so that the shaft does not rotate when the bearing is operating at its normal air pressure.

Air Bearing

Air under pressure passes through rotatable hollow shaft 1 into stationary bearing enclosure 2 and through perforated plate 3 to support tape 4. Reaction motor 5 and counterweight 6 are mounted on the shaft. The weight of the latter is chosen to counterbalance the force of the motor so that the shaft does not rotate when the bearing is operating at its normal air pressure.

If the angle of wrap of the tape increases, the pressure in the bearing increases. This increases the torque of the motor which rotates the shaft clockwise so that plate 7, mounted on the shaft, uncovers more perforations. Thus, as the angle of wrap of the tape increases or decreases, the operative area of the air bearing increases or decreases, respectively.
