Note(s) [2009.01]

  • Combinations including mechanical gearings are classified in groups F16H 37/00or F16H 47/00, unless they are provided for in groups F16H 1/00-F16H 35/00.
  • In this subclass, sets of rigidly-connected members are regarded as single members.
  • In this subclass, the following terms or expressions are used with the meanings indicated:
    • "toothed gearing" includes worm gearing and other gearing involving at least one wheel or sector provided with teeth or the equivalent, except gearing with chains or toothed belts, which is treated as friction gearing;
    • "conveying motion" includes transmitting energy, and means that the applied and resultant motions are of the same kind, though they may differ in, e.g. speed, direction or extent;
    • "rotary" implies that the motion may continue indefinitely.
    • "oscillating" means moving about an axis to an extent which is limited by the construction of the gearing and which may exceed one revolution, the movement being alternately forwards and backwards during continued operation of the gearing;
    • "reciprocating" means moving substantially in a straight line, the movement being alternately forwards and backwards during continued operation of the gearing;
    • "reversing" or "reversal" means that an applied movement in one direction may produce a resultant movement in either of two opposed directions at will;
    • "central gears" includes any gears whose axis is the main axis of the gearing.
