Abstract
The utility model provides an elastic locating sleeve, includes interior steel bushing, outer steel jacket and elastic rubber, its characterized in that: the surface of interior steel bushing with the internal surface of elastic rubber passes through the adhesive and bonds together, the surface of elastic rubber with outer steel jacket's internal surface passes through the adhesive and bonds together, the elastic rubber gives suitably high -volume, makes before vulcanizing outstanding form is personally submitted to the tip glue of elastic rubber, balances out the tensile stress of vulcanizing back rubber shrink and producing in advance, balances out the tensile stress that some vehicle operation in -processs produced to rubber. The utility model discloses an elastic locating sleeve is appearance curve structure when improving the injecting glue vulcanization, has optimized rubber stress concentration's after the vulcanization problem, and product aging resistance can improve greatly.
Description
Technical field
This utility model belongs to flexible member technical field, and specifically to one kind can improve stress, prolongation and use the longevity
The elastic locating sleeve that the employing rubber of life is bondd with metal.
Background technology
Elastic locating sleeve is the vitals of axle-box positioning device, play a part of constraint wheel to framework relative motion.
In train operation, make axle box relative to wheel to being only capable of having relatively small position in the interstice coverage allowed in left and right, fore-and-aft direction
Move.
Elastic locating sleeve applies on bogie for track-guided vehicle, belongs to one kind of bogie rubber nodal point, plays connection
Connection and cushioning effect between car upper body positioning guide column and bogie positioning seat, improves stablizing for rail traffic vehicles operation
Property and comfortableness.It is flexibly positioned be enclosed within running in rise traction and cushioning effect, for train riding quality and operation peace
There is entirely highly important effect；More complicated (the radial-axial compression drawing of elastic locating sleeve stressing conditions in vehicle operation
The comprehensive function such as stretch), on the premise of rigidity requirement is met, improve the service life of elastic locating sleeve it is critical that.Bullet
Property positioning sleeve (application number：200920231371.5), it is proposed that the structure of interior outer steel sleeve and middle spring rubber, and in elasticity
Interference fit is adopted between rubber and outer copper sheathing, makes gum elastic have certain pre-compression force.
But as shown in figure 1, the structural elasticity positioning sleeve of this inner cylinder liner 3, outer steel sleeve 1 and middle spring rubber 2 is adopted
Overcoat 1 is connected with caoutchouc vulcanization with interior inner room 3, and structure is simpler, rubber and metal inner-outer sleeve in traditional mode of production
Between easily occur bond failure or ageing of rubber in use.There is stress concentration after curing and go out often in rubber both ends of the surface
Existing degumming problem.
The content of the invention
For above-mentioned technical problem, the present invention proposes a kind of elastic locating sleeve, extends the service life of product.
To reach above-mentioned purpose, the technical solution used in the present invention is：A kind of elastic locating sleeve, including interior steel bushing, outer steel
Set and gum elastic, the outer surface of described interior steel bushing and the inner surface of gum elastic by together with adhesive bonds, elasticity
Together with the outer surface of rubber passes through adhesive bonds with the inner surface of outer steel sleeve.Give before sulfuration and suitably high-volume balance out sulfur
After change, rubber shrinks the tension for producing.The end glue surface of gum elastic is made before sulfuration in standing shape, after balancing out sulfuration in advance
Rubber shrinks the tension for producing, the tensile stress produced to rubber in balancing out Some vehicles running, extends product
Service life.
It is interference fit between gum elastic and outer steel sleeve, the end of interior steel bushing and outer steel sleeve end higher than gum elastic.
The invention has the advantages that：This product optimizes rubber through improving appearance curve structure when injecting glue vulcanizes
The problem of glue stress concentration after curing, through normal load test, the test of single product radial loaded, single product axially plus
After after load test, reinforcement load comparison's test, as shown by data is improved, structure fatigue life is longer.
Description of the drawings
Elastic locating sleeve schematic cross-sections of the Fig. 1 for prior art.
Elastic locating sleeve schematic cross-sections of the Fig. 2 for the embodiment of the present invention.
In figure, 1 is outer steel sleeve, and 2 is gum elastic, and 3 is interior steel bushing.
Specific embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further with accompanying drawing with reference to embodiment
It is bright.
Embodiment 1：Elastic locating sleeve as shown in Figure 2, including interior steel bushing 3, outer steel sleeve 1 and gum elastic 2, interior steel bushing 3
Outer surface and gum elastic 2 inner surface by together with adhesive bonds, the outer surface and outer steel sleeve 1 of gum elastic 2
Inner surface passes through adhesive bonds together.Make the end glue surface of gum elastic 2 in standing shape curve before sulfuration, balance out in advance
After sulfuration, rubber shrinks the tension for producing, the tensile stress produced to rubber in balancing out Some vehicles running, extends
The service life of product.Interior steel bushing 3 and 1 end of outer steel sleeve are higher than the end of gum elastic 2.And improve on this basis natural
The ageing-resistant performance of rubber, greatly improves product ageing-resistant performance.
Embodiment above technological thought only to illustrate the invention, it is impossible to which protection scope of the present invention is limited with this, it is all
It is any change done on the basis of technical scheme according to technological thought proposed by the present invention, each falls within present invention protection model
Within enclosing.
Claims (2)
1. a kind of elastic locating sleeve, including interior steel bushing, outer steel sleeve and gum elastic, it is characterised in that：The appearance of the interior steel bushing
