Abstract

The utility model relates to an elastic bearing, which comprises a first connecting piece and a second connecting piece, wherein the first and second connecting pieces are positioned at both ends of the elastic bearing. The elastic bearing is characterized in that: a plurality of layers of rubber sheets with buffering and damping functions are adhered between the first and second connecting pieces; and metal linings are adhered at interval among the rubber sheets. Compared with the prior art, the utility model has the advantage that: the rubber sheets are combined with the metal linings to play a role of connection, the rubber sheets have elasticity, and the metal linings also can guarantee connection intensity and carrying capacity, thus, the structure has damping and buffering functions for the strong impact force, and also has the functions of absorption and noise reduction for the noise instantly generated.

Description

Resilient bearing

Technical field

The utility model relates to a kind of bearing with flexible adjustment function, is applicable to that all kinds of machineries such as train, bridge need the field that flexibly connects of rotating.

Background technique

The existing connection that is applicable to that all kinds of machineries such as train, bridge need to rotate generally adopts universal joint, ball bearing to connect, exist and lack flexibility and oneself's adjustment damping, buffering function, the place that rigidity value, damping value are had relatively high expectations is difficult to permanent use, problem is continuous, therefore, how to develop a kind of connection bearing that has damping and buffering function for strong wallop, become the important topic that those skilled in the art need further investigate.

The model utility content

Technical problem to be solved in the utility model is that a kind of resilient bearing that has damping and buffering function for strong wallop is provided at the above-mentioned state of the art.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of resilient bearing, comprise first link and second link that are positioned at two ends, it is characterized in that being bonded with between first link and second link multilayer rubber with buffering and shock-absorbing function, and, be bonded with the metal liner between the sheet rubber at interval.

The described first link inwall has arc-shaped concave, and accordingly, the described second link inwall has arc convex, and described sheet rubber and metal liner then are and described first link and the suitable arc shape of second link.Can satisfy the needs that satisfy angular adjustment under certain condition when connecting like this.

For making metal liner energy holding position in vulcanization of rubber process motionless, described metal liner middle part is provided with the positioning hole of double as exhaust when injecting rubber.The gulde edge that the location was provided with when described metal liner circumferencial direction was outward extended with an injection rubber.

Compared with prior art, advantage of the present utility model is: owing to adopt sheet rubber to use as connecting in conjunction with the metal liner, sheet rubber has elasticity, and the metal liner can guarantee the intensity and the bearing capacity that connect, such structure has damping and buffering function for strong wallop, and the noise that produces for moment has the absorbing sound and lowering noise effect, and the rigidity value of whole connection, damping value can be achieved by the gap length between the adjustment metal liner and the quantity of metal liner.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, resilient bearing in the present embodiment comprises first link 11 and second link 12 that is positioned at two ends, be bonded with multilayer rubber 2 between first link 11 and second link 12 with buffering and shock-absorbing function, and, be bonded with metal liner 3 between the sheet rubber 2 at interval.

First link, 11 inwalls have arc-shaped concave, and accordingly, second link, 12 inwalls have arc convex, and 3 of sheet rubber 2 and metal liners have and first link 11 and the suitable arc shaped surface of second link 12.Design can be satisfied the needs of adjusting angle within the specific limits like this.

As shown in Figure 3, metal liner 3 middle parts are provided with the positioning hole 32 of double as exhaust when injecting rubber.The gulde edge 31 that the location was provided with when metal liner 3 circumferencial directions were outward extended with an injection rubber.

First link 11 and second link 12 in the present embodiment all adopt adpting flange, consider that actual conditions also can adopt other links such as connecting plate.

As shown in Figure 4 and Figure 5, the preparation method of resilient bearing comprises the steps: in the present embodiment

1. first link 11, second link 12 and metal liner 3 are made ball blast, deoiled and processing of rust removing, and guarantee that first link 11, second link 12 and metal liner 3 water curtains reach consistent, first link 11, second link 12 and metal liner 3 are coated the primary coat adhesive respectively earlier then, after the drying, be coated with top coating adhesive again, dry back is stand-by;

2. metal liner 3 usefulness locating studs being passed positioning hole 32 makes Primary Location and guarantees to have between the metal liner 3 interval, with eight positioning tools 6 metal liner 3 is fenced up then and use positioning ring 51 and following positioning ring 52 clip positioning tools, take out locating stud, simultaneously first link 11 is hung on positioning tool 6 upper end portions and and uppermost metal liner 3 between leave the gap, with second link 12 place positioning tool 6 underparts and and nethermost metal liner 3 between leave the gap, form a clip integral piece, be provided with in each positioning tool 6 and lead between the metal liner 3, reach the feeding-passage 61 in gap between the metal liner 3 and second link 12 between the metal liner 3 and first link 11, for making 3 accurate positionings of metal liner make things convenient for the vulcanization of rubber, metal liner 3 circumferencial directions are outward extended with a gulde edge 31, accordingly, positioning tool 6 inwalls have the locating slot that is provided with for gulde edge 31;

3. the clip integral piece is placed on the lower plate 42, and cover with upper die plate 41, template 43 in being provided with between lower plate 42 and the upper die plate 41, should middle template 43 be positioned at positioning tool 6 peripheries, in feeding-passage 61, inject rubber then and carry out vulcanizing treatment, air is then discharged by positioning hole 32, and the cooling back vulcanization of rubber is formation sheet rubber 2 between metal liner 3, between metal liner 3 and first link 11 and in the space between the metal liner 3 and second link 12.
