Generally, for most of articulated structure, as shown in Figure 1, second component 2 forms a fork configuration, and
It is defined on second component 2 in machinery field providing the part of pin hole as side bearing.Side bearing generally comprises two plates, and two
A space, i.e., aforementioned fork configuration are constrained out between a plate, which is used to provide for being included in the first component 1
The part of pin hole, in machinery field, it is intermediate support usually to define the part for being used for providing pin hole on the first component 1.Correspondingly,
In the utility model, it is intermediate pin hole to define the pin hole part on intermediate support, and it is side pin hole to define the pin hole on side bearing,
So intermediate pin hole is aligned with side pin hole, axis pin 7 is then worn, so as to combine axis pin assembling structure as shown in Figure 1.
It is understood that the space that side bearing is constrained is interior, refer to inward direction be inside, opposite direction be to
Outside.
And it is to be appreciated that axis pin 7 generally uses cylindrical pin in rolling cage shoe, the hinge of corresponding formation is
Cylindrical hinge is designed generally according to shaft bse system, axial on the basis of the axis of axis pin 7, radially, axially with circumferential except spy
It does not mentionlet alone outside bright, on the basis of axis pin 7.
In machinery field, side bearing generally selects transition with the cooperation of axis pin 7 and the cooperation of intermediate support and axis pin 7

Also swelling effect can be generated, both ends swelling is substantially also corresponded to, belongs to equivalent both ends swelling.
Generally use transition coordinates between side pin hole and axis pin 7 in the prior art, and in the embodiment of the utility model, then
It is interference fit based on swelling, used by essence, is interference fitted, especially the structure of big at both ends and small in middle, to a certain degree
On additional axial limit structure can be no longer set.But it for equipment reliability of operation, in the construction shown in fig. 1, goes back
Conical head 4 is provided, which is equipped with the straight mouth platform 43 that diameter is more than pin hole aperture, for the axial direction limit of axis pin 7
Position, in this regard, can hereinafter be described in detail.
Axis pin assembling structure shown in Fig. 1 uses the structure to 7 both ends swelling of axis pin, and it is first to remember such expanding structure
Expanding structure, the axis pin assembling structure being applicable in are first structure；In the aforementioned structure that 7 both ends of axis pin are carried out with equivalent swelling
The one end for carrying out active swelling is the second expanding structure, and the axis pin assembling structure being applicable in is the second structure；The second swelling knot
Structure in some implementations can be identical with the first expanding structure, such realization is mainly reflected in and can be generated when carrying out swelling
The axial movement of axis pin 7.
In addition, in Fig. 1, the end face of the straight mouth platforms 43 of two conical heads 4 with second set 3 contacts, to this needs plus
With explanation, it is that structure shown in FIG. 1 belongs to both ends swelling, technical conditions are that conical head 4 needs to produce with axis pin 7 axially
Raw relative motion, in a state that axis pin 7 is opposing stationary, two conical heads 4 cannot axially generate interference with second set 3,
In other words, conical head 4 and second set 3 should be there are gaps, for the adjustment of conical head 4.
If using identical construction for the second expanding structure, the straight mouth platform 43 of conical head 4 and second set 3
End face generates contact, and to form support, when carrying out such as when screwing of screw 5, axis pin 7 can be moved to end where the second expanding structure
It moves and forms swelling.
For the first expanding structure, expansion set may be used, expansion set swelling precision is high, but high expensive.
In a preferred embodiment, for the first expanding structure with the second expanding structure using identical expanding structure, this kind swollen
The choosing principles of locking structure are that structure is relatively easy, at low cost, and swelling is reliable.

The requirement to 5 pretightning force of screw can be reduced, facilitate adjustment.
It is also related with the taper of bellmouth 71 to tapered portion 42 and then about the pretightning force of screw 5, if it is considered that structure
Reliability, with reduce vibration etc. caused by 7 end swelling of axis pin disappearance or decrease, between tapered portion 42 and bellmouth 71
Cooperation should can generate self-locking, it is clear that when taper is smaller, tapered portion 42 and bellmouth 71 coordinate caused by pressure angle it is remote
Less than angle of friction, self-locking can be generated, therefore, the taper of bellmouth 71 is not preferably greater than 1:1, in this regard, can be based on angle of friction into
Row selection, and it is not limited to 1:1 taper.But the taper of tapered portion 42 and bellmouth 71 is unsuitable too small, otherwise can increase screw 5
Adjustment amount influences the constraint distance of straight mouth platform 43.1 is not preferably less than accordingly, with respect to the taper of bellmouth 71:12.
In addition, about the axial joint-cutting, quantity is 2 ~ 6, preferably selects the even numbers items such as 2,4 or 6, matches two-by-two
It is symmetric about the axis, to facilitate processing.
In addition, about the second structure, one end of axis pin 7 is needed to itself have certain taper, primarily served passive swollen
Tight effect has one end of taper about axis pin 7, and the taper of gabarit is 1:24~1:12.
Routinely, the first component 1 forms the intermediate support of axis pin 7, and corresponding intermediate pin hole usually requires to set wear-resisting
Bushing to improve service life, but seldom considers side bearing, i.e., such as the pin hole part in Fig. 1 on second component 2（Side pin hole）'s
Service life problem.
In the embodiment of the utility model, since pin hole is still cylinder pin hole, and the end of axis pin 7 be based on swelling and
Become bullet, although if the end swelling degree of axis pin 7 is smaller, the taper of bullet is relatively small, but still side can be caused to sell
