GEARING
{
( steering of motor vehicles by differentially driving ground-engaging elements on opposite vehicle sides B62D 11/02 )
}
NOTE
-
1. Combinations including mechanical gearings are classified in groups F16H 37/00 or F16H 47/00 , unless they are provided for in groups F16H 1/00 to F16H 35/00 .
2. In this subclass, sets of rigidly-connected members are regarded as single members.
3. 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
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. Attention is drawn to the following places:

A01D 69/06 Gearings in harvesting machines

Guide Heading:
Control of gearings conveying rotary motion( orbital toothed gearings with a secondary drive in order to vary the speed ratio of driving or feeding mechanisms of machine tools B23Q 5/12 , B23Q 5/46 ; conjoint control of drive units for vehicles B60K 41/00 ; cycle transmissions B62M ; marine propulsion B63H )
NOTE
-
Attention is drawn to the Notes following group B60K 41/00 .

In groups F16H 59/00 to F16H 63/00 , clutches positioned within a gearbox are considered as comprising part of the gearings.

In groups F16H 59/00 to F16H 63/00 , the following terms or expressions are used with the meaning indicated:

- "final output element" means the final element which is
moved to establish a gear ratio, i.e. which achieves the
linking between two power transmission means, e.g. reverse
idler gear, gear cluster, coupling sleeve, apply piston
of a hydraulic clutch;
- "mechanism" means a kinematic chain consisting either of a
single element or alternatively of a series of elements,
the position of each point on the kinematic chain being
derivable from the position of any other point on the chain,
and therefore, for a given position of a point on one of
the elements forming the kinematic chain there is only one
position for each of the other points on the elements
forming the kinematic chain;
- "final output mechanism" means the mechanism which includes
the final output element;
- "actuating mechanism" means the mechanism, the movement of
which causes the movement of another mechanism by being in
mutual contact;
- "final actuating mechanism" means the mechanism actuating
the final output mechanism.
-
{
"mechanical force" means the force transmitted by an
actuating mechanism or the human body
}

Combinations of features individually covered by group F16H 61/00 and one or both of groups F16H 59/00 and F16H 63/00 are classified in group F16H 61/00 .

Combinations of features individually covered by groups F16H 59/00 and F16H 63/00 are classified in group F16H 63/00 .

When classifying in groups F16H 59/00 to F16H 63/00 , control inputs or types of gearing, which are not identified by the preceding notes concerning combinations, and which are considered to represent information of interest for search, may also be classified. Such non-obligatory classification should be given as "additional information", e.g. selected from subgroup F16H 61/66 relating to the type of gearing controlled or from group F16H 59/00 relating to control inputs
