Quick-acting couplings in which the parts are connected by simply bringing them together axially

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Couplings for rigidly connecting two coaxial shafts or other movable machine elements > Quick-acting couplings in which the parts are connected by simply bringing them together axially

CPC:

Couplings for rigidly connecting two coaxial shafts or other movable machine elements (attachment of wheels to axles for railway carriages B60B; for attachment of cranks to their shafts F16C3/10) > Quick-acting couplings in which the parts are connected by simply bringing them together axially

CPC subdivides this area 3x more granularly than IPC with 3 additional codes.

3 codes are CPC-only extensions.

Note: 2 CPC extensions are marked as secondary classification only.

IPC defines codes here since 1995.
