Abstract

The utility model relates to a rubber spring comprising a solid rubber inner core. A coaxial central through hole is formed in the solid rubber inner core. A cord fabric line layer is arranged on the outer side of the solid rubber inner core. A surface material layer is arranged on the outer layer of the cord fabric line layer. Two ends of the solid rubber inner core are of circular-truncated-cone-shaped structures. The rubber spring has the advantages that the rubber spring is small in mounting size, corrosion resistant, long in service life, low in cost and free of maintenance; noise can be effectively reduced, complete compression of a spiral spring can be avoided, and damage to mechanical structure due to broken components during failure of the spiral spring is avoided; the rubber spring has stable deformation quantity, enhanced stability under a high compression ratio, high bearing capacity and excellent vibration isolation capability.

Description

A kind of rubber spring

Technical field

The utility model relates to a kind of rubber spring.

Background technique

Spring is a kind of conventional mechanical part, be widely used in damping in mechanical structure, provide in the mechanical structure of restoring force or the power of obstruction, but the making material that present spring adopts is all steel, steel are as a kind of conventional metallic material, there is the characteristics such as the intensity, hardness, fatigue strength of metallic material, the phenomenon that this causes spring to there will be excessive fatigue, elastic force to reduce after work a period of time, and then cause because the inefficacy of spring causes the mechanical structure at place and lose its due function, thereby cause inevitable loss to user.Therefore, should further improve prior art.

Model utility content

The purpose of this utility model is to provide a kind of rubber spring, to overcome currently available technology above shortcomings.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of rubber spring, comprises solid rubber inner core, and in described solid rubber, in-core is provided with coaxial central through bore, and the outside of solid rubber inner core is provided with cord line layer; Described cord line layer outside is provided with surface material layer.

The two ends of described solid rubber inner core are frustoconic shape structure.

The beneficial effects of the utility model are: installation dimension is little; Corrosion-resistant, long service life; Cost is low, non-maintaining; Can effectively reduce noise; Can avoid occurring that helical spring is compressed to the situation at the end; While avoiding occurring that helical spring lost efficacy, its cracked parts cause the situation of damage to mechanical structure; There is stable deformation quantity, under higher compression factor, there is the stability of enhancing; There is high bearing capacity; There is outstanding vibration isolation ability.

Accompanying drawing explanation

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the structural representation of a kind of rubber spring described in the utility model embodiment;

Fig. 2 is a kind of rubber spring described in the utility model embodiment use state reference map in vibrating feeder;

Fig. 3 is a kind of rubber spring described in the utility model embodiment use state reference map in tension force snubber.

In figure:

1, solid rubber inner core; 2, cord line layer; 3, surface material layer; 4, central through bore; 5, rubber spring; 6, vibrating feeder.

Embodiment

As shown in Figure 1, a kind of rubber spring described in the utility model embodiment, comprises solid rubber inner core 1, in described solid rubber inner core 1, is provided with coaxial central through bore 4, and the outside of solid rubber inner core 1 is provided with cord line layer 2; Described cord line layer 2 outside are provided with surface material layer 3.The two ends of described solid rubber inner core 1 are frustoconic shape structure.

When concrete use, as shown in Figure 2, the rubber spring 5 that the utility model is provided is arranged on to be needed in the vibrating feeder of damping 6, when mounted, central through bore in solid rubber inner core 14 is enclosed within on the support of fixing damping device in existing mechanism, in the time that equipment moves, rubber spring 5 can provide high bearing capacity and outstanding vibration isolation ability, and can avoid occurring that helical spring lost efficacy time, its cracked parts cause the situation of damage to mechanical structure; In the time of concrete use, the rubber spring 5 that the utility model provides can also be as the parts that tension force is provided, as shown in Figure 3, rubber spring 5 can replace helical spring, is applied in the machinery that tension force is provided, rubber spring 5 is owing to adopting rubber material, its efficient deformation amount is almost constant, and helical spring elastic stiffness is a constant, and its effective deformation equals practical distortion, this makes rubber spring 5 with respect to helical spring, has installation dimension little; Corrosion-resistant, the advantage of long service life.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technological scheme, within all dropping on protection domain of the present utility model.
