When, the first crank 71 drives axis of the first connecting rod axle journal 72 around the shaft end of the first bent axle 7 to rotate, and the shaft end of the second bent axle 8 turns
Dynamic to be connected on the second axle bed 3, when the second bent axle 8 rotates, the second crank 81 drives second connecting rod axle journal 82 around the second bent axle 8
The axis of shaft end rotates.
In one optional embodiment of the embodiment of the present invention, spacing A be the first bent axle 7 from bottom dead center position around first axle
When the axis both clockwise of slot is rotated by 90 °, the distance between first connecting rod axle journal 72 and substrate 4 of the first bent axle 7;Spacing B is the
When two bent axles 8 are rotated by 90 ° from bottom dead center position around the axis of the second axial trough counterclockwise, the second connecting rod axle journal 82 of the second bent axle 8
The distance between substrate 4.
As shown in fig. 7, the first bent axle 7 is located at bottom dead center position, when the first bent axle 7 from bottom dead center position around the first axial trough
When axis both clockwise is rotated by 90 °, the first bent axle 7 is located at left dead-centre position, is engaged with second gear 10 by first gear 9, the
Two gears 10 drive axis of second bent axle 8 from bottom dead center position around the second axial trough to be rotated by 90 ° counterclockwise, and the second axial trough is located at
Right dead-centre position measures the distance between first connecting rod axle journal 72 and substrate 4 and second connecting rod axle journal 82 and substrate 4 at this time
Between distance, by comparing difference i.e. can determine whether synchronism qualified.
As shown in figure 9, in another optional embodiment of the embodiment of the present invention, spacing A is the first bent axle 7 from lower dead center
When position rotates 270 degree around the axis both clockwise of the first axial trough, between the first connecting rod axle journal 72 and substrate 4 of the first bent axle 7
Distance, at this time the first bent axle 7 be located at right stop;Spacing B is for the second bent axle 8 from bottom dead center position around the axis inverse time of the second axial trough
Needle rotate 270 degree when, distance between the second connecting rod axle journal 82 and substrate 4 of the second bent axle 8, at this time the second bent axle 8 stop positioned at a left side
Point.When being located at left stop and right dead-centre position by being respectively compared the first bent axle 7, the difference between spacing A and spacing B, thus
The influence that the shaft end cylindricity of the first bent axle 7 and the second bent axle 8 judges synchronism can be eliminated, to which complete examination first is bent
The synchronism of axis 7 and the second bent axle 8.It should be noted that the left stop of the first signified bent axle 7 and right dead-centre position herein,
Only it is the 72 stroke left end of first connecting rod axle journal ensured under naked eyes recognition capability and right end, first gear 9 and the second tooth
The rotation of wheel 10, can be by being finely adjusted manually.
Specifically, two point crank synchronization adjustment method further includes:Second gear 10 is adjusted to revolve around the shaft end of the second bent axle 8
Turn, and the step of fixed 10 and second bent axle 8 of second gear, the step for make the difference range of spacing A and spacing B be-
0.03mm~0.03mm.
As shown in Figure 10, keyway, second gear 10 and the second bent axle 8 are machined on second gear 10 and the second bent axle 8
Keyway between be plugged with special-shaped key 101;Special-shaped key 101 is plugged in the part of second gear 10 relative to 101 grafting of special-shaped key
In the part of the second bent axle 8 around the axis deviation of the second bent axle 8.When the difference of spacing A and spacing B be less than -0.03mm, alternatively,
When the difference of spacing A and spacing B are more than 0.03mm, second gear 10 and the second bent axle 8 are carried out using special-shaped key 101 circumferential solid
Fixed, the part that special-shaped key 101 is plugged in second gear 10 is plugged in the part of the second bent axle 8 around second relative to special-shaped key 101
The axis deviation of bent axle 8 makes to be machined with the second gear 10 of keyway originally and the second bent axle 8 generates relatively by special-shaped key 101
Rotation, and then achieve the purpose that adjust the first bent axle 7 and 8 synchronism of the second bent axle, the deflection ruler of the skew direction of special-shaped key 101
The very little mathematic interpolation all in accordance with spacing A and spacing B, computational methods can be obtained by passing through known geometric algorithm, and can pass through trial
Different special-shaped keys 101 are until the difference of spacing A and spacing B is achieved in synchronization in the range of -0.03mm~0.03mm
Property adjustment.
In addition to above-mentioned synchronism method of adjustment, keyway A can also be processed on the second bent axle 8, when spacing A's and spacing B
When difference range is -0.03mm~0.03mm, the position of the keyway A on corresponding second bent axle 8 is crossed mark in second gear 10
Note, and keyway B is processed in mark, and then determine the keyway position in second gear 10, it also can get good synchronism tune
Whole effect.
Finally it should be noted that:The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations;To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, it will be understood by those of ordinary skill in the art that:Its according to
So can with technical scheme described in the above embodiments is modified, either to which part or all technical features into
Row equivalent replacement;And these modifications or replacements, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
