Scope

This standard specifies a single criterion for balancing the individual parts (shaft or rotor, mating parts) of a keyed assembly, with the aim of adapting all the parts being balanced so that when assembled they meet the overall balance of the assembly and ( or) vibration tolerance. This standard requires the use of half-keys when balancing the individual parts of keyed assemblies to avoid balance errors that would occur when using full-key or no-key criteria. This standard applies to the balancing of rotors on a balancing machine, on the rotor's own frame or on site, and is also applicable to the measurement of residual unbalance and vibration severity of rotors with keyways (without fittings). Although the drawings of this standard show rectangular or square flat keys of equal cross-section mounted parallel to the axis of the shaft, this standard also applies to keys, half-round keys, wedge keys, pins and keys mounted on tapered shafts. other special keys. The principles of the half-key criterion outlined in the definitions and specific applications of other chapters also apply to other special keys such as special shapes and configurations. This standard includes implementation rules (see appendix A) and rules for the transition period when the half-key criterion is adopted in the future (see appendix B).
