using gears having orbital motion

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Toothed gearings for conveying rotary motion with variable gear ratio or for reversing rotary motion > using gears having orbital motion

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) > using gears having orbital motion

Of 11 combined children, 8 exist in both systems.

3 codes are CPC-only extensions.

Note: 3 CPC extensions are marked as secondary classification only.

2 shared codes have differing titles between IPC and CPC.
