Therefore, related domain is needed badly and exploitation a kind of cooperation with bearing base is easy to dismantle and the strong rubber bush bearing of circumferential crystallized ability.
Summary of the invention
The purpose of this utility model is the above-mentioned defect overcoming prior art, provides a kind of rubber bush bearing, and this rubber bush bearing can be easy to dismantle and have very strong circumferential crystallized ability in bearing base.
Inventor of the present utility model is found by large quantity research and discloses the relation of the size of rubber bush bearing and the damping exponent C of bearing base, along with the increase of damping exponent C, the circumferential crystallized ability of rubber bush bearing reduces gradually, simultaneously, along with the increase of damping exponent C, the dismounting of rubber bush bearing and bearing base is more prone to.
To achieve these goals, the utility model provides a kind of rubber bush bearing, wherein, described rubber bush bearing comprises bearing body and is formed in the outer surface of described bearing body distributes vertically symmetrically convex stupefied, described convex stupefied surface is curved, described convex stupefied summit is substantially all on a cylindrical, and the size of described rubber bush bearing and the damping exponent C of bearing base meet following relation:
, wherein, d
1for diameter of a circle outside described convex stupefied place, summit, d
2for the diameter of described bearing body, a is the chord length of described convex stupefied and circular arc that described bearing body is crossing, and b is the length of rubber bush bearing axis, D is the internal diameter of bearing base, and 18.33≤C≤23.43, be more preferably 18.54≤C≤21.27, most preferably be 19.54≤C≤19.85.
In the utility model, described convex stupefied quantity can be determined according to actual needs, and can be such as 8-16, preferably, described convex stupefied quantity be 12.
In the utility model, the length of described rubber bush bearing axis refers to that bearing body has convex stupefied part length vertically.
In the utility model, the front of described bearing body can also have multiple groove be uniformly distributed circumferentially.
In the utility model, the material for described rubber bush bearing can be the rubber that related domain routine uses, such as, can be natural rubber or synthetic rubber.Described synthetic rubber can be styrene butadiene rubber, nitrile butadiene rubber, ethylene propylene rubber or neoprene.Those skilled in the art can select according to actual needs and can carry out suitable combination.
The beneficial effects of the utility model are: the utility model can pass through the configuration size of different rubber bush bearing and the internal diameter of bearing base, to adjust the damping exponent C of rubber bush bearing and bearing base.When damping exponent C is in 18.33-23.43 scope, the circumferential crystallized ability of rubber bush bearing can satisfy the demands and especially easily dismantle; When damping exponent C is in 18.54-21.27 scope, rubber bush bearing has the simultaneously certain easy degree of dismounting of good circumferential crystallized ability; When damping exponent C is in 19.54-19.85 scope, rubber bush bearing has good circumferential crystallized ability simultaneously than being easier to dismounting, and combination property is optimum.
Other features and advantages of the utility model are described in detail in embodiment part subsequently.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, term " front " refers to rubber bush bearing vertically near the face of flow fan; " side " refers to the face that rubber bush bearing is radially observed.
In a kind of embodiment of the present utility model, as shown in Figure 1 and Figure 2, described rubber bush bearing comprises bearing body 100 and to be formed on the outer surface of described bearing body 100 equally distributed 12 convex stupefied 101 vertically, described convex stupefied surface is curved, described convex stupefied summit is substantially all on a cylindrical, and the size of described rubber bush bearing and the damping exponent C of bearing base meet following relation:
, wherein, d
1for diameter of a circle outside described convex stupefied place, summit, d
2for the diameter of described bearing body 100, a is the chord length of described convex stupefied and circular arc that described bearing body 100 is crossing, and b is the length of rubber bush bearing axis, and D is the internal diameter of bearing base.The length b of described rubber bush bearing axis refers to that bearing body has convex stupefied part length vertically.
In another embodiment, the front of described bearing body 100 can also have multiple groove 200 be uniformly distributed circumferentially.
Provide the relation of the sized data of 23 groups of rubber bush bearings as shown in Figure 1 and Figure 2, the size of bearing base and damping exponent C below, concrete data are as shown in table 1.
Table 1
23 groups of embodiments in table 1, when the internal diameter D of bearing base is fixed as 32.20mm, along with the change of the size of rubber bush bearing, circumference crystallized ability divides 1 to 5 grade of change, the circumferential crystallized ability of the larger expression of progression is stronger, dismantle easy degree and divide 1 to 5 grade, the easier dismounting separation from bearing base of progression larger expression rubber bush bearing.
In Table 1, described circumferential crystallized ability determines by measuring the moment of torsion of different size rubber bush bearing in bearing base, is divided into 5 grades according to the size of moment of torsion.The easy degree of described dismounting is measured by rigid bearing base to determine from the pulling force of bearing base pull-out rubber bush bearing, is divided into 5 grades according to pulling force size.
Can be found out by the contrast of embodiment each in table 1, when damping exponent C increases, the circumferential crystallized ability of rubber bush bearing reduces, and dismantles the enhancing of easy degree; When damping exponent C reduces, the circumferential crystallized ability of rubber bush bearing strengthens, and dismantles the reduction of easy degree.Further, when damping exponent C is in 18.33-23.43 scope, the circumferential crystallized ability of rubber bush bearing can satisfy the demands and the easy degree of certain dismounting; When damping exponent C is in 18.54-21.27 scope, rubber bush bearing has good circumferential crystallized ability and has preferably easily dismounting degree simultaneously; When damping exponent C is in 19.54-19.85 scope, rubber bush bearing has good circumferential crystallized ability simultaneously than being easier to dismounting, and combination property is optimum.
More than describe preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
