Abstract
The utility model provides a wear -resisting rubber connector, including the rubber sleeve, set up to be in respectively the flange at rubber sleeve both ends, the cross section of rubber sleeve is constituting to the reverse flank that extends in both sides with the both ends of two U -shaped structures of flange center pin symmetry and U -shaped structure. Still including the metal elastic element of bonding on rubber sleeve inner wall, the bottom of U -shaped structure is equipped with metal elastic element clearance portion, the metal elastic element be in clearance portion bilateral symmetry sets up. The utility model discloses it erodees the performance to have excellent stand wear and tear, resistant dust particle. The realization is guaranteeing the inboard wear resistant while of rubber connector, guaranteed again rubber connector have can be good displacement deformability.
Description
Technical field
The utility model relates to a kind of abrasive rubber joint, is especially applied to the elastomer connector that wear-resistant, the resistance to particle in the environment such as dust granules washes away, belongs to field of mechanical technique.
Background technique
In recent years, elastomer connector is widely used in pressure piping and drains in pipeline system, has bit shift compensation, eliminates stress, reduces the function such as noise, absorbing vibration.Compared with traditional non-metal expansion joint, there is the advantages such as withstand voltage height, resistance to negative pressure and noise reduction, compared with type metal expansion joint, have from heavy and light, absorb the advantages such as displacement amount is large and corrosion-resistant.But the elastomer connector of ordinary construction in the market in actual use, especially serious occasion is washed away at dust granules etc., due to reasons such as itself the wear-resisting grade restrictions of abrasive rubber, application is restricted, and there is problems such as leaking, the serious and life of product of inner glue layer surface abrasion is low.
Model utility content
Technical problem to be solved in the utility model is, exists under dust granules washes away serious condition, there is the easy serious wear of inner glue layer or worn out problem, a kind of abrasive rubber joint of design for General Purpose Rubber joint.
In order to solve above technical problem, the utility model provides a kind of abrasive rubber joint, comprise rubber bush, be separately positioned on the adpting flange at described rubber bush two ends, the cross section of described rubber bush is that the flank oppositely extended to both sides with the two ends of axisymmetric two the U-shaped structures of flange center and U-shaped structure is formed.It is characterized in that: also comprise the metallic elastic component be bonded on rubber bush inwall; The bottom of described U-shaped structure is provided with metallic elastic component clearance portion, and described metallic elastic component is arranged in described clearance portion bilateral symmetry.
The technological scheme that the utility model limits further is:
Further, the length of described metallic elastic component clearance portion is not less than 1/3 of U-shaped structural base total length.
Further, described rubber bush comprises rubber cord, is coated in the inside and outside rubber layer of rubber cord both sides.
Further, the both sides, end of the U-shaped structure of described rubber bush are respectively equipped with a circle steel ring.
Further, described metallic elastic component is made up of a pair high elasticity abrasion-proof metal half bellows.
Further, described metallic elastic component is bonded together by the inner glue layer of adhesive and rubber bush.
The beneficial effects of the utility model are: the utility model has excellent wear-resistant, the performance of flushing of resistance to dust granules.While realization is wear-resisting inside guarantee elastomer connector, in turn ensure that elastomer connector has displacement deformation ability that can be good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
embodiment 1
A kind of abrasive rubber joint that the present embodiment provides, as shown in Figure 1: comprise rubber bush 1, be separately positioned on the adpting flange 2 at described rubber bush 1 two ends, the cross section of described rubber bush 1 is that the flank 4 oppositely extended to both sides with the two ends of axisymmetric two the U-shaped structures 3 in flange 2 center and U-shaped structure 3 is formed.Also comprise the high elasticity abrasion-proof metallic elastic component 5 be bonded on rubber bush 1 inwall.The bottom of described U-shaped structure 3 is provided with metallic elastic component clearance portion 6, and described high elasticity abrasion-proof metallic elastic component 5 is arranged in described clearance portion 6 bilateral symmetry.Described high elasticity abrasion-proof metallic elastic component 5 is bonded together by the inner glue layer 1-2 of adhesive and rubber bush 1.
The length of described high elasticity abrasion-proof metallic elastic component 5 clearance portion 6 is not less than 1/3 of total length bottom U-shaped structure 3.Described rubber bush 1 comprises rubber cord 1-1, is coated in inside and outside rubber layer 1-2,1-3 of rubber cord both sides.The both sides, end of described U-shaped structure 3 are respectively equipped with a circle steel ring 1-4.Metallic elastic component 5 is made up of a pair high elasticity abrasion-proof metal half bellows.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
