Abstract: A method and apparatus for providing precisely controlled micro-indexing of rotational elements utilizes a bidirectionally controllable linear force actuator in combination with a self-locking linkage mechanism to frictionally grip and to impart a pure turning moment to the rotational element. The method and apparatus disclosed are especially advantageous for use with large rotational elements, such as the rotors of gas turbines. The indexing method inserts a minimal amount of stored energy into a system thereby virtually eliminating overshoot. In a preferred embodiment comprised of a pair of symmetrical indexing sections, the desired micro-indexing is accomplished while imposing no additional loading on the rotational element.

Abstract: A dynamic balancing system for rotary elements wherein balance is maintained by remote control of mass distribution during rotation. A fluid balancing mass partially fills three or more annular chambers. A change in mass distribution is achieved by heating the fluid in a chamber and conducting the vapor so produced to the opposite chamber(s) where the vapor condenses. A warmer chamber thereby loses mass to a cooler chamber. Electronic vibration measuring means and control are generally employed to determine which chambers and what degree of heating are required to improve the state of balance. The preferred control is electronic and comprises a stationarily mounted encoding portion and rotationally mounted decoding portion. Power and encoded control signals are transmitted via inductively coupled coils from the encoding portion to the decoding portion.
