Bending section 7 is shown by bending section midpoint 700 and by bending section circle 800.In figure 3 especially perpendicular to plan, extension
Bending section axis can be regarded as by the axis at bending section midpoint 700.Bending section axis is determined perpendicular to 100 ground of rotation axis all the time
To.But since side face 7 extends around rotation axis 100, so side face 7 and not having bending section axis identical all the time.Cam disc 3
The each section for also extending through rotation axis 100 there is the bending section axis of oneself.But each bending section circle of side face 7
800 are in a plane with rotation axis 100 all the time.In the example depicted in fig. 3, which corresponds to plan.Bending
Portion's circle 800 is following circle, and the midpoint of the circle is bending section midpoint 700.Side face 7 justifies 800 advantageous by least one bending section
Circular arc form.The circular arc that side face 7 can especially justify 800 by multiple bending sections is formed so that especially can also realize pair of side face
Number trend.
Figure 3 illustrates the bending section circle 800 with constant radius.Alternatively, the radius of the bending section of side face 7 is not permanent
It is fixed.Especially set, radius logarithmically increases from lateral edges 11s.Especially set, medially at the radius between side 10
Between 5000 millimeters to 15000 millimeters, preferably between 8000 millimeters to 12000 millimeters, particularly preferably 10000 millimeters.
Radius in lateral edges 11 is preferably between 1 millimeter to 500 millimeters, preferably between 5 millimeters to 250 millimeters, particularly preferably 10
Millimeter.
Fig. 4 schematically shows the comparison between the radius of constant radius and logarithm trend.Fig. 5 shows to belong to two kinds of radiuses
Hertzian pressure.The trend of outer surface 7 is schematically illustrated with section view in Fig. 4.The zero point of the curve map corresponds to herein
The following point of outer surface 7, the point are centrally located between two lateral edges 11.First curve 30 shows to work as bending section radius from zero
Point towards side 10 logarithmically decline when side face 7 trend.Second curve 40 shows walking for when bending section constant-radius side face 7
