Abstract
The utility model relates to an elastic positioning sleeve, which is characterized in that an inner steel sleeve, an outer steel sleeve and elastic rubber are included; the outer surface of the inner steel sleeve and the inner surface of the elastic rubber are vulcanized and bonded together; the outer surface of the elastic rubber and the inner surface of the outer steel sleeve are bonded together by a bonding agent; and the elastic rubber and outer steel sleeve are in interference fit. The elastic positioning sleeve adopts the structure with the inner and the outer steel sleeves and the middle elastic rubber, and the elastic rubber and outer steel sleeve are in interference fit, so that the elastic rubber has a certain pre-compression force, which can eliminate tensile stress generated by displacement of the inner and the outer steel sleeves; the delamination problem of the elastic rubber and the metal steel sleeves, and the rubber cracking problem in the use process, are well solved; the running safety of a vehicle is ensured; and the maintenance cost of the vehicle is reduced.
Description
Technical field
The utility model relates to a kind of locating bush, specifically relates to a kind of improve employing rubber and the bonding elastic locating sleeve of metal stressed, that increase the service life, belongs to the elastic element technical field.
Background technology
Elastic locating sleeve applies on the passenger car bogie, belongs to a kind of of bogie truck rubber nodal point, plays the connection and the cushioning effect that connect between passenger vehicle upper body positioning guide column and the bogie truck positioning seat, improves the stability and the traveling comfort of passenger train operation.Elastic locating sleeve plays traction and buffering effect in operational process, for the riding quality and the safe in operation of train crucial effect is arranged; Elastic locating sleeve stressing conditions more complicated in vehicle operating process combined actions such as () radial-axial compression stretchings is satisfying under the prerequisite of rigidity requirement, and be vital the service life of improving elastic locating sleeve.
Be installed in the elastic locating sleeve on the passenger car bogie, often occur the product rubber glue phenomenon of splitting and come unglued in the past in the use, vehicle operating safety is caused very big potential danger; Change increasing of the rate of repairing simultaneously and also strengthened service expenditure, mainly be because the elastic locating sleeve of each manufacturer production all is the sulfuration bonding mode under free state, there is not the magnitude of interference between the parts, because elastic locating sleeve is stressed comparatively complicated, especially drawing stress, cause degumming phenomenon easily, cause shorten greatly the service life of elastic locating sleeve, increased cost.
The utility model content
For solving prior art problems, the purpose of this utility model provides a kind of later-model elastic locating sleeve, can improve stressing conditions, actv. prolongs the service life of product, solved and often occurred the product rubber glue phenomenon of splitting and come unglued in the use in the past, vehicle operating safety is improved guarantee, reduced the maintenance cost of vehicle simultaneously.
For achieving the above object, the utility model is to realize by following technical scheme:
A kind of elastic locating sleeve, it is characterized in that comprising interior steel bushing, outer steel sleeve and elastic caoutchouc, the sulfuration of the inside face of the outside face of steel bushing and elastic caoutchouc bonds together in described, the outside face of elastic caoutchouc is in the same place by adhesive bonds with the inside face of outer steel sleeve, and is interference fit between elastic caoutchouc and the outer steel sleeve.
Aforesaid elastic locating sleeve is characterized in that described interior steel bushing and outer steel sleeve, and its end is higher than the end of elastic caoutchouc.
The beneficial effects of the utility model are: elastic locating sleeve of the present utility model, adopted the structure of interior outer steel sleeve and middle elastic caoutchouc, and between elastic caoutchouc and outer steel sleeve, adopt interference fit, make elastic caoutchouc that certain pre-compression force be arranged, in use can eliminate the drawing stress that produces owing to interior outer steel sleeve displacement in the use, solved the problem that rubber glue splits in the problem of coming unglued of elastic caoutchouc and metal steel bushing and the use well, guarantee the safe in operation of vehicle, reduced the maintenance cost of vehicle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Now by following preferential embodiment the utility model is carried out non-limitative illustration and explanation, these embodiment only provide as an example with reference to accompanying drawing.
Fig. 1 is a structural representation of the present utility model.As shown in the figure, elastic locating sleeve of the present utility model, steel bushing 1, outer steel sleeve 3 and elastic caoutchouc 2 in comprising, the inside face of the outside face of interior steel bushing 1 and elastic caoutchouc 2 bonds together by sulfuration, the inside face of the outside face of elastic caoutchouc 2 and outer steel sleeve 3 by adhesive bonds together, elastic caoutchouc 2 adopts the mode of interference fit to combine with outer steel sleeve 3, makes 3 pairs of elastic caoutchoucs 2 of outer steel sleeve that certain pre-compression force be arranged.And the end of interior steel bushing 1 and outer steel sleeve 3 will be higher than the end of elastic caoutchouc 2, is convenient to install and protection elastic caoutchouc 2.
When producing the utility model, with interior steel bushing 1 and elastic caoutchouc 2 presulfurization moulding, elastic caoutchouc 2 has certain magnitude of interference with respect to outer steel sleeve 3 earlier, and just the outer circumference diameter of elastic caoutchouc 2 is greater than the inner periphery diameter of outer steel sleeve 3.With the inside face coating adhesive of outer steel sleeve 3, the sulfuration half-blank of interior steel bushing 1 elastic caoutchouc and 2 is pressed in the outer steel sleeve 3, make elastic caoutchouc 2 that suitable compressive force be arranged, to eliminate the tensile force that produces in the use.60-80 ℃ of following cured adhesive under lower temperature makes elastic caoutchouc 2 and outer steel sleeve 3 strong bond together.
The utility model is verified data are as follows:
Radial weight 5KN, product distortion 0.55-0.75mm is radially tired: live load 0.5-9.8KN, frequency 2-5HZ, tired 1,000,000 times; Axial fatigue: live load 0.5-3.92KN, frequency 2-5HZ, tired 1,000,000 times.
Test results proves that this utility model meets the requirements fully.
The utility model has adopted the structure of interior outer steel sleeve and middle elastic caoutchouc, and between elastic caoutchouc 2 and outer steel sleeve 3, adopt interference fit, make elastic caoutchouc that certain pre-compression force be arranged, in use can eliminate the drawing stress that produces owing to interior outer steel sleeve displacement in the use, solved the problem that rubber glue splits in the problem of coming unglued of elastic caoutchouc and metal steel bushing and the use well, guarantee the safe in operation of vehicle, reduced the maintenance cost of vehicle.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of this patent requirement.
