A.1 Worldwide past usage of key conventions
Figures
1 Major types of shaft keyways and keys
2 Contoured half-key set
C.1 Half-height key set
C.2 Half-length key (for shaft only), its centre of
gravity located in the same transverse plane as
that of the full key in the final assembly
C.3 Half-length key used for balancing fitment
C.4 Stepped (final) key for short fitment
C.5 Average-length (final) key for short fitment in
ideal position
C.6 Average-length (final) key for short fitment
mounted flush with shaft end, producing balancing
error
C.7 Stationary and operational key positions
C.8 Translation of key-caused quasi-static balancing
error into shaft (rotor) correction planes
C.9 Shaft keyway machines with end mill cutter
C.10 Shaft keyway machined with a key slot cutter
D.1 Internal moments created when a full key is
corrected by two correction masses on the rotor
body
Applies to rotors balanced in balancing machines, in their own housing and in situ.
