Description

The stressed rubber shock absorber in a kind of inclined-plane

Technical field

The utility model relates to a kind of vibration damper, especially relates to a kind of rubber shock absorber, belongs to the environmental protection machinery field.

Background technique

At present, for the medium and small machinery that produces impact shock, for example press machine, punch press, diesel generator, shearing machine, planer, milling machine, grinding machine, drilling machine, injection machine, grinder etc., the impact shock that is produced is a kind of nuisance vibration, especially be installed in the machinery on the floor, bigger to floor and surrounding environment influence.At present, the method of eliminating impact shock generally adopts the rubber damper on plane, or on the supporting surface of flat rubber pad, increase the protrusion striped of some different direction, to subdue the vibration of side direction, utilize the elasticity of rubber to have the vibration of absorption and the bigger characteristics of damping constant are subdued vibration, size according to vibration, select the rubber pad of different-thickness for use, or adopt the multilayer rubber pad, but the residual vibration behind the load weight of machinery and the impact shock vibration damping still connects to be delivered to by rubber pad the basis is installed.For overcoming the shortcoming that the flat rubber pad exists, what a kind of Ω of being shape was arranged shears vibration damper to shear stressed rubber, though this kind vibration damper has enlarged attachment face, rubber base is concentrated to be delivered on the little attachment face of vibration damper area but its load weight and residual vibration are still by shearing, and still has shortcoming and defect.

Summary of the invention

The purpose of this utility model is: the advantage that keeps above-mentioned rubber shock absorber, eliminate above-mentioned shortcoming and defect, provide a kind of inclined-plane stressed rubber shock absorber, impact shock can be comprised that vertical impact vibration and lateral impact are vibrated utilizes that the inclined-plane is stressed to be delivered on tilted-putted block rubber and the M type pedestal thereof, residual vibration behind the load weight of machinery and the impact shock vibration damping is not to be directly delivered to install on the basis, and M type pedestal is big with the area of contact that the basis is installed, can disperse the load weight and the residual vibration of machinery, reach vibration damping, vibration isolation, relax the purpose of impacting and reducing solid-borne sound transmission.

For achieving the above object, the technical solution adopted in the utility model is: adopt two blocks of (or 4) nitrile butadiene rubbers as damping block, be positioned over the angle of inclination that becomes 60 ° of angles with horizontal plane on the inclined-plane of M type metal pedestal, the centre of two inclination damping blocks, be provided with the trapezoidal supporting base of falling of hollow, the supporting surface of supporting base has a flat rubber damping pad, the central position of supporting base is provided with the level(l)ing mechanism of can regulate level, also there is a flat rubber damping pad bottom surface of M type metal pedestal, constitutes the stressed rubber shock absorber in inclined-plane.

The impact shock of machinery at first is delivered to down the flat rubber damping pad on the trapezoidal supporting seat surface, be absorbed part vibration, all the other vibrations pass to two inclination rubber damping pieces by falling two sides of trapezoidal supporting base with the inclined-plane force way, the vibration major part is absorbed, remaining impact shock then is delivered to the flat rubber damping pad of bottom surface by M type metal pedestal, be absorbed again, vibration has been absorbed basically fully through just being absorbed by triple vibration dampings, and M type metal pedestal basal area is big, the machinery load weight evenly can be delivered to the basis is installed.

The utlity model has simple in structurely, the stressed area of contact in inclined-plane is big, stressed evenly, characteristics such as lateral stiffness is stable, and bearing capacity is strong.Because the structural type uniqueness has triple vibration-damping functions, can fully show the characteristic of its stressed effect in inclined-plane, the vibration damping and vibration isolation effect is remarkable.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 looks schematic representation for the utility model embodiment one master, as shown in Figure 1, main structure of the present utility model is placed in the

block rubber

8,9 on two inclined-planes of M shape pedestal 10 and the trapezoidal supporting bases 7 that fall that are placed in the middle of two

inclination block rubbers

8,9 are constituted by M shape metal pedestal 10 and two.

Two inclined-planes of M shape pedestal and the angle of horizontal plane are the best with 60 ° generally through testing in many ways, testing, and certainly, also can select other angles for use according to the situation that machinery produces impact shock.

Block rubber

8,9 adopts oil resistants, corrosion-resistant, ageing-resistant butyronitrile composite, its effect is to bear down trapezoidal supporting base 7 with incline plane type to transmit the machinery load weight of coming and absorb most impact shock, and be passed to M shape pedestal 10 with incline plane type, the inclined-plane surface of contact is big, and it is remarkable to absorb the impact shock effect.

M shape pedestal 10 adopts metal spheroidal graphite cast iron or other made that is suitable for, and its effect is to bear the next machinery load weight of

block rubber

8,9 transmission and remaining impact shock after

block rubber

8,9 absorbs.

Pedestal rubber pad 12 bears the machinery load weight and absorbs remaining impact shock, impact shock is weakened to minimum, the impact shock that machinery produced passes through adjustable support seat rubber pad 3 or falls the absorption of trapezoidal supporting base rubber pad 6, major part through

inclination block rubber

8,9 absorbs again, pass through the absorption of pedestal rubber pad 12 again, basically, absorbed fully, so the utility model, has significant absorption vibrating effect with the particular structure form.

The trapezoidal supporting base 7 that falls also is to adopt metal spheroidal graphite cast iron or other suitable material manufacturings, its effect is that machinery is directly installed on its supporting surface, direct bearing load weight and impact shock, and absorb a part of impact shock energy earlier by the trapezoidal supporting base rubber pad 6 of falling on its supporting surface, then, by its inclined-plane, both sides machinery load weight and impact shock are passed to block

rubber

8,9 with incline plane type.

Regulate bolt 5, adjustable support seat 4, fastening nut 2, clamping bolt 1 constitutes level(l)ing mechanism, its effect be when the machinery needs that need vibration damping more than 1 vibration damper and the position that contacts with vibration damper not on same horizontal plane or the basis is installed when height is arranged, can be by the adjusting of level(l)ing mechanism, make machinery be in level, be particularly suitable for requiring the machinery of level installation, when machinery does not need horizontal adjustment, can be screwed to and fall trapezoidal supporting base rubber pad 6 and closely contact regulating bolt 5, perhaps take off the adjusting bolt 5 of horizontal adjustment machinery, adjustable support seat 4, fastening nut 2 and clamping bolt 1, change clamping bolt 13 as shown in Figure 4 in addition, clamping washer 14 and fastening nut 15, machinery is directly installed on down on the trapezoidal supporting base rubber pad 6, then by tightening tightly because of nut 15 and clamping bolt 13 solid mechanical equipment, to adapt to the vibration damping requirement of different machinery.

The effect of pedestal bolt hole 11 is that vibration damper is connected by bolton with the installation basis.

Fig. 5 looks schematic representation for the utility model embodiment two master, and power 6 is the plan view of material 5.

As Fig. 5, shown in Figure 6, when the impact shock of machinery is big, can adopt the design of two M shape pedestals with cross arrangement, 4

block rubbers

19,20,23,18 are set, fall the then side's of changing into cone supporting base 17 of trapezoidal supporting base 7, equipment side's cone supporting base rubber pad 16 on it, the pedestal bottom is provided with 4 pedestal bolts hole 24, and effect, principle is all identical with the foregoing description one.
