Balance Test Indexing Tool for Balance-Testing a Rotor

A system, comprising:

• a modular balance test indexing tool system for assisting with balancing a rotor of machinery on a balance testing machine having a drive mechanism, said modular balance test indexing tool system including:
• a rotor mount surface disposed on the rotor;
• a balance testing machine arbor configured to be coupled between the drive mechanism of the balance testing machine and said rotor mount surface, wherein said rotor mount surface and said balance testing machine arbor cooperate with one another to provide a first indexing coupling between the drive mechanism and the rotor when the rotor, said rotor mount surface and said arbor are installed in the balance testing machine;
• and
• a balancing simulator configured to be coupled between the drive mechanism of the balance testing machine and said rotor mount, wherein said rotor mount surface and said balancing simulator cooperate with one another to provide a second indexing coupling between the drive mechanism and the rotor.

A balance test indexing tool for use in balance-testing a rotor, the rotor being a component of a separate rotating machine having a machine function other than balance-testing and having a rotor surface symmetrically disposed about an axis of rotation of the rotor, said tool comprising:

• a rotor mount receiver having a flange extending radially from a shaft, said rotor mount receiver defining a receiver face;
• a kinematic half mount disposed on said receiver face;
• a mount surface formed directly in said symmetrically disposed rotor surface, said mount surface including a coupling half mount configured to mate with said receiver face half mount, such that said kinematic half mount and said coupling half mount together form a kinematic mount between the rotor and rotor mount receiver;
• and
• means biasing the mount surface and receiver together.
