with two or more countershafts

Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

Toothed gearings for conveying rotary motion with variable gear ratio or for reversing rotary motion > without gears having orbital motion > exclusively or essentially with continuously- meshing gears, that can be disengaged from their shafts > characterised by the disposition of the gears > with two or more countershafts

CPC:

Toothed gearings for conveying rotary motion with variable gear ratio or for reversing rotary motion (speed-changing or reversing mechanisms F16H59/00 - F16H63/00) > without gears having orbital motion > exclusively or essentially with continuously meshing gears, that can be disengaged from their shafts > characterised by the disposition of the gears (F16H3/083, F16H3/085 take precedence) > with two or more countershafts

CPC subdivides this area 4x more granularly than IPC with 5 additional codes.

5 codes are CPC-only extensions.

Note: 5 CPC extensions are marked as secondary classification only.

IPC defines codes here since 1990.
