Content that the present invention is further explained.
As shown in Figures 4 and 5, a kind of axlebox rod rubber arthrosis, including mandrel 1, rubber layer 2 and housing 3, rubber layer
2 outer end type face is the circular arc concave surface 2.1 inwardly concaved, and the circular arc concave surface 2.1 connects by inclined-plane 1 and 3 inner wall of housing
It connects, the inclined-plane 1 moves closer to 3 inner wall of housing from inside to outside.Mandrel 1, rubber layer 2 and housing 3 pass through vulcanization bonding
Together, sulfuric horizon is formed.
In the present embodiment in order to enable rubber layer when loaded by axlebox rod rubber arthrosis after radial precompressed
Uniform force does not occur fold, Fold, is to inwardly concave and with circular arc concave surface 2.1 and inclined-plane by rubber layer whole design
The upper half of the proximity opening shape of one 2.2 transition connection, circular arc concave surface 2.1 is adjacent to because radial precompressed with inclined-plane 1,
Lower half is in flat, so that rubber outer end type face uniform force, is not in fold, Fold.
Transition is carried out by transition face 2.3 between the circular arc concave surface 2.1 and inclined-plane 1, the transition face 2.3 is
The circular arc concave surface inwardly concaved.
In the present embodiment, in order to make circular arc concave surface 2.1 and inclined-plane 1 when radial precompressed, the two is adjacent to coincidence
Process is unlikely to directly to fold, in the junction on circular arc concave surface 2.1 and inclined-plane 1 using the circular arc concave surface conduct inwardly concaved
Transition face 2.3.
The rubber layer 2 mandrel 1 and housing 3 radial precompressed amount H, the arc radius R3, H/4 of transition face 2.3≤
The maximum spacing of R3≤H/2, transition face 2.3 and 3 inner wall of housing is H/2 ~ 2R3.In order to make rubber arthrosis by radial precompressed
After the precommpression of contracting amount H, the upper half of circular arc concave surface 2.1 can be conformed to completely on inclined-plane 1, be learnt by largely testing
When the arc radius R3 of transition face 2.3 meets H/4≤R3≤H/2, the maximum spacing of transition face 2.3 and 3 inner wall of housing be H/2 ~
When 2R3, it can guarantee that the upper half of circular arc concave surface 2.1 can conform to completely on inclined-plane 1.

It is best.As shown in Figures 7 and 8, when the angle of adjustable inclined surface apparatus 1 and housing 3, the upper semisection of circular arc concave surface 2.1 will with it is oblique
Face 1 is more than one 2.2 end of inclined-plane after being whether overlapped or be overlapped inside inclined-plane 1, and rubber layer outer mold surface is all deposited
In certain angle, when causing axlebox rod rubber arthrosis loaded, the angle can be folding and crack, cause to influence anti-
Fatigue behaviour, the only angle of adjustable inclined surface apparatus 1 and housing 3, in axlebox rod rubber arthrosis after radial precompressed amount H
Can be as shown in figure 9, the upper semisection of circular arc concave surface 2.1 will be just overlapped in the end on inclined-plane 1 with inclined-plane 1, rubber at this time
The outer end type face anti-fatigue performance of glue-line 2 is best.
It is spherical surface section among the mandrel 1, the spherical surface section is by intermediate arc section 11.1 and two sides arc section 11.2
It is connected smoothly to be formed, by increasing the radius of intermediate arc section 11.1 and two sides arc section 11.2, so that the thickness of rubber layer 2
Degree increases, to improve the anti-fatigue performance of axlebox rod rubber arthrosis.
It is spherical surface section among 3 inner wall of housing, the spherical surface section is by intermediate arc section 23.1 and two sides arc section
23.2 are connected smoothly to be formed, by increasing the radius of intermediate arc section 23.1 and two sides arc section 23.2, so that rubber layer 2
Thickness increase, to improve the anti-fatigue performance of axlebox rod rubber arthrosis.It is outer by further increasing in the present embodiment
The cambered surface radius of set 3 and 1 spherical surface section of mandrel, keeps spherical surface section gentler, constant in axlebox rod rubber arthrosis outer dimension
Under shape condition, the thickness of rubber layer 2 is increased, to further improve the anti-fatigue performance of axlebox rod rubber arthrosis.
Obviously, the embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed,
But it cannot be understood as the limitations to patent of invention range.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to of the invention
Protection scope.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
