Abstract
The utility model relates to a vibration damper, which is used for various movement machinery and vehicles. The utility model is composed of a protective jacket, a connecting seat and a vibration damping element; the vibration damping element is made of a rubber or plastic rubber spring and is provided with a plurality of vibration damping grooves, and a lower protective jacket base is provided with exhaust eyelets. The utility model has the advantages of simple structure, good vibration damping effect and long service life.
Description
The utility model relates to a kind of playing vibration isolation, weakening, keeping away the vibration damper of the usefulness of bestirring oneself of various machineries and vehicle that be applicable to.
In order to alleviate the vibration that machinery causes in movement process, people have designed metal coil spring, metal plate springs, air pressure vibration absorber, hydraulic pressure vibration absorber, the part but various vibration damper also comes with some shortcomings, the metal coil spring effectiveness in vibration suppression is bad, metal plate springs is owing to structural reason, working life is short, air pressure and hydraulic pressure vibration absorber manufacturing process complexity, the cost height, be afraid of most the gas leakage leakage of oil, in case the gas leakage leakage of oil will integral body be scrapped, and present most of vibration damper can not adapt to the elimination of high, medium and low frequency vibration.
The purpose of this utility model provides that a kind of weakening is effective, long service life, low, easily manufactured machinery and the ride-control of cost.
The utility model is achieved in that vibration damper comprises connecting base, sheath and damping element, be characterized in that damping element makes with rubber or elastomeric plastics, have several absorbing grooves above, the center has the hole, and damping element is contained in the protective metal shell, two ends use spiral shell select and fixed by nut on connecting base, sheath is similar to air pressure or dydraulic shock absorber, is divided into upper jacket and lower jacket, and the internal diameter of upper jacket is bigger slightly than the external diameter of lower jacket, damping element is designed to taper, perhaps cylindricality as required.Varying strength is made in its segmentation, and promptly top intensity is big, and the bottom, middle part is soft slightly, or the bottom is soft slightly, and middle part, top hardness is big slightly, produces pressurized gas damage glue spring and sheath in order to make when the glue spring is past to press down, and has several air holes in sheath lower end cap bottom.
The utility model compared with the prior art, its substantive distinguishing features and progress are:
1. wide accommodation can be used for the weakening of various movable machineries, also can be applicable to the weakening of automobile, motorcycle, lorry, tractor.
2. can be used for the mechanical vibration occasion of various high, medium and low frequencies, weakening is effective.
3. simple in structure, easy to maintenance, working life is longer.
4. avoided the gas leakage of air pressure or hydraulic pressure vibration absorber, the shortcoming that leakage of oil is promptly scrapped, cost is lower.
Below in conjunction with accompanying drawing enforcement structure of the present utility model is described:
Accompanying drawing is mounted in the damper structure schematic representation on machinery or the vehicle.
From figure, see, vibration damper is made of upper connecting base 1, lower connecting base 11 and upper jacket 6, lower jacket 7 and the damping element 4 that is contained in the sheath, damping element 4 is made for rubber glue spring or elastomeric plastics glue spring, have several absorbing grooves 5 above, the center has hole 8, two ends are connected with lower connecting base 11 with upper connecting base 1 with following hold-doun nut 9 with last hold-doun nut 3 with the spiral shell select, damping element 4 can be designed to cylindricality or taper according to different needs, its glue spring intensity sectional difference is provided with exhaust hole 10 at the bottom cover of lower jacket 7.
