- F16H 3/46 Gearings having only two central gears, connected by orbital gears (F16H3/68 - F16H3/78 take precedence)
- F16H 3/62 Gearings having three or more central gears (F16H3/68 - F16H3/78 take precedence)
- F16H 3/68 in which an orbital gear has an axis crossing the main axis of the gearing and has helical teeth or is a worm
- F16H 3/70 in which the central axis of the gearing lies inside the periphery of an orbital gear
- F16H 3/72 with a secondary drive, e.g. regulating motor, in order to vary speed continuously
- F16H 3/74 Complexes, not using actuatable speed-changing or regulating members, e.g. with gear ratio determined by free play of frictional or other forces
- F16H 3/76 with an orbital gear having teeth formed or arranged for obtaining multiple gear ratios, e.g. nearly infinitely variable
- F16H 3/78 Special adaptation of synchronisation mechanisms to these gearings
