This standard presents metric dimensions, tolerances,
sizes and fits for straight bores, tapered
bores, keys and keyways for unmounted industrial
flexible couplings. The keys and keyways followed
the recommendations of ISO R773:1969 and shaft
tolerances followed ISO R775:1969. Shaft keyseat
dimensions and tolerances were given in ISO
R773:1969. This specification includes index tolerances
for multiple keyways.
Inspection methods for straight and tapered bores
and keyways are included in the annexes. The
annexes also include the recommended design
practice for tapered shafts for use with flexible
couplings.
1.1 Application area
This standard is applicable to couplings as defined in
ANSI/AGMA 9009--D02, Nomenclature for Flexible
Couplings, with metric bores and keyways.
1.2 Excluded area
This standard does not apply to couplings attached
to shafts without keys (see ANSI/AGMA 9003--A91),
shafts and bores with tapered keys, inch bores with
metric keyways, metric bores with inch keyways,
inch bores with inch keyways, or shaft keyseat
tolerances. See ANSI/AGMA 9002--B04 for inch
bores with inch keyways.
