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 > in which an orbital gear has an axis crossing the main axis of the gearing and has helical teeth or is a worm

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 > in which an orbital gear has an axis crossing the main axis of the gearing and has helical teeth or is a worm
