In Fig. 9 the structural determination of the effective length of the adjusting lever is illustrated.

The main or pivot axis of the impeller 104 is arranged so that it points to the center of the drawn cross-sectional circle of the tree trunk to be processed halfway up the processing area, and the extension α away from the pivot point 107 is drawn so that it is parallel to the pivot center line 109 of the Impeller 104 is located. A perpendicular to the pivot center line 109 is drawn through the end point UO of the extension β at right angles to the extension α and meets the main axis at the point Ul. On the vertical itself, away from the point of intersection Ul, the quantity \ (c t- d) is plotted to the right and left, the endpoints obtained being points 113 and 114 , and c and d the lengths of the chords between points 108 and 110, respectively. UO and 112 of the arc described by the end of the extension when adjusting by the angle y χ. At the two end points 113 and 114 , viewed from point Ul, an angle of (90 ° -j- *) is created, the new legs 116, 117 with the pivot center line 109 result in the intersection 115 at which the legs 116, 117 with of the pivot center line each form the angle \ .1 \. The distance between the point of intersection 115 and the point 111 is the effective length L vh of the linkage sought for the impeller 104 F i g. 10 shows an adjusting lever 119 on an impeller 120. This adjusting lever is not perpendicular to a plane of rotation of the impeller 120, but should have a favorable middle position for the transmission of motion from a driving connection point 118 between the end positions in which the impeller 120 is to run . Such an adjusting lever 119 does not have to lie in a plane perpendicular to the pivot center line. The pivot point on the adjusting lever can also be moved in a plane perpendicular to the pivoting center line of the impeller when pivoting if the adjusting lever protrudes at an angle from the pivot axis and / or if a part protruding away from the adjusting lever in a fixed, also inclined position carries the pivot point. The effective length L vh of the adjusting lever is then the vertical distance of the leak point from the pivot center line.

This means that the effective lever length of the adjusting lever is proportional to the extension α

and the "sine" of half the pivot angle for the frame part II from its position with the position of the impeller 102 " and inversely proportional to the" tangent "of half the difference between the largest and the smallest pitch angle im

Working area of the chassis. Strictly speaking, these relationships initially only apply to a constant pitch if the specified prerequisites are at least approximately fulfilled.
However, as is easy to see, there are deviations

of the above-mentioned prerequisites by no means critical. This is especially true because

Furthermore, it can be equated with a close approximation

1. As in FIG. 9 makes visible, the working area of the frame between the positions of the frame

₄ j partly II between 102 "and 102, relative to the whole area, in which the frame part is pivotable II, is relatively small,

2. the pivoting from the central position to the limit positions for the frame part II, the

Lengthening α and the steering ratio are relatively small and the source of error is small,

3. when choosing thicker tree trunks and greater length for the lever arm 106 with a frame with a different work area or when choosing one

larger lever length in the present chassis, the angle β is partly smaller, so that the angles are relatively small, and

4. The pitch h cannot be selected to be very large, since the power for the drive machine

not very large can be chosen for such chassis, otherwise the machines or devices in question will be too heavy and too big. With a small pitch, the angle Δ » also remains relatively small.

The connection point on the frame Il ju side

the pivot point 107 are arranged, as can the frame part is shown III on the lever 123, also be provided on the lever itself, so that the connection SO dot 122 gives The ideas and contexts for the adjusting lever and its effective length of stay for the impeller 105 the same as for the adjustment lever on the impeller 104. However, the fact that the connection point 108 is on an extension α and the connection point 120 is on the lever 123 itself deserves the observation that the one adjustment lever should be moved in a certain direction , e.g. B. that of the impeller 104, pulled from the adjusting rod and the other lever, that of the impeller 105 , must be pressed in order to reach the continuously changing position of the wheels to change the pitch angle ζ.

Finally, the impeller on frame part II can also be used. However, the path for the adjustment of the second impeller with a length other than that shown can also be chosen so that the lever 106 can be equipped. Then for the second impeller of the first impeller at its Verdie impellers 102 and 104 are adjusted by a connecting rod with constant shutdown stands for the connection points as a result of an ao that the movements of the first impeller according to another angle β according to formula 13 other effective der different positions on the tree trunk for the adjustment lever. changes to the second impeller.
