Specific embodiment
Example of the invention in attached drawing is described referring to reference frame as shown in Figure 1.
Reference frame has the first axle A1 for limiting axial direction.Second axis A2 is perpendicular to first axle A1.
In the central point C that the intersection of first axle and second axis is the concentric spherical surface of the concentric member of shaft coupling.First axle
Line and second axis and central point are located in the first plane P1, and first axle and central point are located at vertical with the first plane the
In two plane P2.Third plane P3 across central point C is perpendicular to other planes.Third axis A3 is limited to perpendicular to axis A1
And A2, and be located in third plane and pass through central point C.
First axle A1 is torque axis, for example, on first axle A1, drive shaft or it is driven be pivotally connected to shaft coupling,
Second axis A2 and third axis A3 is the axis of the relative rotation of shaft coupling.
In other examples, shaft coupling is with some components centered on central point C and with another central point C2
Other components at center, when component alignment, another central point C2 is deviated along first axle A1 from C.From the offset of C
Amount C2 can be a small amount of e.g. a few tenths of a mm.It is respectively parallel to other two axial lines A21 and the A31 difference of axis A2 and A3
Across central point C2.
In Fig. 2, shaft coupling includes the inner annular member 201 around first axle A1.Internal component 201 includes surrounding
The spherical segment of central point C and have outer spherical surface S1, outer spherical surface S1 is to be with the central point C of first axle
The convex surface at center is spherical.Internal component 201 has center circle cylindrical 40, and in this example, center circle cylindrical 40, which has, to be used
In the spline 42 for engaging corresponding splined shaft.
It is outer with internal component 201 that outer annular member 202, which has internal spherical surface S21, internal spherical surface S21,
The convex surface of surface S1 complementation is spherical.Concave spherical surface S21 is with the central point C on axis identical with the spherical surface of inner loop
Centered on.In this example, the outer spherical surface S1 of the internal spherical surface S21 and internal component 201 of external rings are contact

One section of sphere centered on heart point C.
In Fig. 2, as shown, there are two diametrically opposite axis X1 and X11 of the load shared on shaft coupling.Joining
Axis device is designed to that one can be ignored in the case where operation under underload.
The static application that there is the example of Fig. 2 such as center wheel hub as shown in Figure 3 to turn to.
In Fig. 3, the steering wheel hub 62 of wheel is supported by supporting member 64, and supporting member 64 is outstanding in this example
Arm.Cantilever 64 is attached to by the shaft coupling E1 as described in referring to Fig. 2 turns to wheel hub 62.Arm 64 is for example bonded on shaft coupling by spline

The half of degree (being packed into slot can also see in fig. 7 c).Slit is sized such that the opposed ground 6 of the diameter of slit in
The interval between diameters of the outer surface S1 of portion's component 1 are opened (including being provided with the retainer 101 such as Fig. 7).The width etc. of each slit
In or less times greater than internal component width.Internal component 1 is to being introduced on one side in the slit as shown in Figure 11 A and with back spin
It goes in plane identical with external component 2.The axis hole of a pair of of component 1 and 2 is aligned at the appropriate stage of assembling process.
The option enables each component to be process as solid material part and makes the mistake as caused by being coupled halfbody
Lose risk minimization.Described method enables whole supporting surfaces described in this specification to be continuous, that is, avoids
The junction that the component assembled by two halfbodies for being bolted or welding together is coupled any connector (because
And atenuator region).
In Figure 11, a pair of of component 1 and 2 is 401 and 402,402 and 403, Fig. 6 in 201 and 202, Fig. 4 in Fig. 2 respectively
