Appendix 6-A Balancing Terminology NOTE The definitions followed by a number are taken from ISO 1925 2nd Edition. Amount of Unbalance The quantitative measure of unbalance in a rotor referred to a plane without referring to its angular position. It is obtained by taking the product of the unbalance mass and the distance of its center of gravity from the shaft axis. Angle of Unbalance Given a polar coordinate system fixed in a plane perpendicular to the shaft axis and rotating with the rotor the polar angle at which an unbalance mass is located with reference to the given coordinate system. Angle Indicator The device used to indicate the angle of unbalance. Angle Reference Generator In balancing a device used to generate a signal which defines the angular position of the rotor. Angle Reference Marks Marks placed on a rotor to denote an angle reference system fixed in the rotor they may be optical magnetic mechanical or radioactive. Balancing A procedure by which the mass distribution of a rotor is checked and if necessary adjusted in order to ensure that the vibration of the journals and or forces on the bearings at a frequency corresponding to service speed are within .
