The same and inclined structure of homogeneous angular, but not having this structure can not also.
(embodiment 1)
Then, the manufacturing method (production method) of resilient bushing 6 is illustrated.Resilient bushing 6 with above structure
It is there is the symmetrical shape of center line C, and there is specific feature when assembling outer member 11.
That is, relatively moving elastic component 10 and outer member 11 to axis direction, and outer member 11 is externally embedded to
After the outer embedding technology a (referring to Fig. 2 (a)) of elastic component 10 in the state of in central axis 7 are mounted in outside, compression work is carried out
Skill b, to make resilient bushing 6, wherein compression process b is, by being externally embedded to portion mounted in inclination in outer member 11, outer
The corresponding part 11t of 10A carries out undergauge processing, and thus compression inclination is externally embedded between corresponding part 11t and inclination outer peripheral surface 13
The technique of portion 10A (referring to Fig. 2 (b)).
In addition, in order to be easy successfully to carry out outer embedding technology a, the diameter of outer member 11 is set to slightly big straight
Diameter, and by whole diameter reducing process after outer embedding technology a and carry out before compression process b can also, wherein the whole contracting
Diameter technique carries out undergauge to the whole of outer member 11 in a manner of being embedded in big outer peripheral surface 17a outside outer member 11 is just close.
Specifically, firstly, as shown in Fig. 2 (a), each inclination periphery is embedded in by the way that each inclination to be externally embedded to outside portion 10A
Face 13 and it will be embedded in major diameter face 16 outside annular membrane portion 10b, and is embedded in breast wheel 17 each inclination to be externally embedded to outside portion 10A
The methods of hot sticky or bonding by Vulcanization is carried out under state, thus prepare in advance to be formed integrated breast wheel 17, elastic component 10 and
Central axis 7.
For the outer diameter for the elastic component 10 being pre-compressed not yet, i.e., for the big outer peripheral surface 17a of breast wheel 17
Diameter and outer member 11 internal diameter for, from successfully carry out outer embedding technology a in terms of preferably equal value, but
It is also possible to unequal value.
In this case, each inclination of left and right is externally embedded to portion 10A and is compressed not yet, therefore, as elastic component 10
Entire width D is the width between two breast wheels 17 in left and right, and the entire width D between the breast wheel 17,17 significantly compares
The entire width d long (D > d) of the outer member 11 under certain diameter state before shortening processing.
Then, if outer embedding technology a terminates, the compression process b as shown in Fig. 2 (b) is carried out.In compression process b, lead to
The processing unit such as turntable type press machine is crossed, by diameter more towards the one end in the axle center direction P more in a manner of becoming smaller to outer member 11
Left and right ends portion carry out undergauge processing (compress processing).It is processed by the undergauge to form inclination in left and right and be externally embedded to portion 10A's
In technique, the end of outer member 11, i.e. corresponding part 11t are forcibly fitted into tapered outer circumferential surfaces 17b by undergauge processing,
Thus each inclination is externally embedded to portion 10A and forcibly moves in the axle center direction P towards direction close to each other via breast wheel 17.
At this point, portion 10A is externally embedded to the inclination that inclination inner peripheral surface 12 and inclination outer peripheral surface 13 are clamped, towards elastic component 10
The direction and the axle center direction P at left and right center, that is, each portion 10A, 10A of being externally embedded to is towards direction close to each other and relative to axle center P
The two directions of the direction of undergauge are compressed, thus formed be pre-compressed by compression unit 14.As a result, having inclination periphery
Face 13 and each inclination inner peripheral surface 12 that left and right is separately positioned on by the elastic component 10 of compression unit 14.
That is, in compression process b, with formed the internal diameter of corresponding part 11t more towards the axle center direction P one end become smaller
The mode of inclination inner peripheral surface 12 carries out undergauge processing, and to inclination be externally embedded to portion 10A towards relative to axle center P undergauge direction and
It is compressed in the two directions of the axle center direction P.
In the present embodiment, the undergauge for being used to bear corresponding part 11t is processed to the metal of adjoint strong compressing force
Breast wheel 17 processed is arranged in elastic component 10, for example, in the feelings for the machining stress for being almost subjected only to hole shrinkage direction or the axle center direction P
Under condition, elastic component 10 can also be only made of rubber.In addition, for elastic component 10, the left and right width of space part 10B
Smaller or radial amount of recess less can also, or without space part 10B can also.
As shown in figure 5, the embedded hole 4H of cover 4 can be formed to following shape: it is wide to increase left and right directions (the axle center direction P)
The internal diameter of the central portion of degree and form diameter with towards the gradually smaller inclination inner peripheral surface 18 in both ends, and its section cooperation outside
The concave shape of 11 shape of component.If it is this shape, in the state of being assembled by bolt 9, the inclination inner peripheral surface 18 of left and right
It is preferred in terms of this respect as preventing resilient bushing 6 from functioning to the anticreep wall that the axle center direction P falls off.
(other embodiments)
