W/D NO S/S WAITING FOR REPLACEMENT

This standard presents metric dimensions, tolerances, sizes andfits for straight bores, tapered bores, keys and keyways forunmounted industrial flexible couplings. The keys and keywaysfollowed the recommendations of ISO R773:1969 and shaft tolerancesfollowed ISO R775:1969. Shaft keyseat dimensions and toleranceswere given in ISO R773:1969. This specification includes indextolerances for multiple keyways. Inspection methods for straightand tapered bores and keyways are included in the annexes.

The annexes also include the recommended design practice fortapered shafts for use with flexible couplings. 

Application

This standard is applicable to couplings as defined in ANSI/AGMA9009-D02, Flexible Couplings – Nomenclature for FlexibleCouplings, with metric bores and keyways.

Exceptions

This standard does not apply to:

– couplings attached to shafts without keys, see ANSI/AGMA9103-B08;

– couplings attached to shafts with tapered bushings or keylessshaft locking devices;

– shafts and bores with tapered keys;

– inch bores with metric keyways;

– metric bores with inch keyways;

– metric bores with metric keyways; or

– shaft keyseat tolerances.

See ANSI/AGMA 9002-C14 for inch bores with inch keyways.
