DIFF Subgroup
F16H 15/04

Gearings providing a continuous range of gear ratios

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Gearings for conveying rotary motion with variable gear ratio, or for reversing rotary motion, by friction between rotary members > without members having orbital motion > Gearings providing a continuous range of gear ratios

CPC:

Gearings for conveying rotary motion with variable gear ratio, or for reversing rotary motion, by friction between rotary members (control of change-speed or reversing-gearings conveying rotary motion F16H59/00 - F16H63/00) > without members having orbital motion > Gearings providing a continuous range of gear ratios

IPC and CPC are identically structured here. All 4 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.
