Abstract
The utility model discloses a vibration damper, which comprises a rubber vibration damping body, a coat, a separator and a spindle. The coat wraps the rubber vibration damping body. The separator is embedded in the central section of the rubber vibration damping body. The spindle penetrates the longitudinal central shaft of the rubber vibration damping body and the separator. The connection part of the spindle and the separator is equipped with a protruding step portion, so that the spindle is supported on the separator. The cross section of the rubber vibration damping body is in a petal shape. According to the utility model, the anti-torsion and anti-deformation performance of the vibration damper is substantially enhanced and the damping performance thereof is significantly improved.
Description
Technical field
The utility model belongs to the environmental protection machinery field, relates to a kind of vibration damper specifically.
Background technique
The vibration of machinery not only can make a noise, and also can produce adverse influence to the basis of support.The present general rubber pad that adopts reduces vibration, and according to the thickness of the size decision rubber pad that vibrates, vibration equipment is big more, and the rubber pad of employing is thick more, because the thickness of rubber pad is big more, the big more effectiveness in vibration suppression of the energy that is consumed is good more.But rubber pad is thick more, and antitorque distortion-free ability is just poor more, and therefore the function of rubber pad has been subjected to restriction.
Summary of the invention
The purpose of this utility model is in order to solve the problem of the antitorque distortion-free ability of thick rubber pad, to improve the vibration-damping function of rubber.
Realize that the above-mentioned purpose the technical solution of the utility model is that a kind of vibration damper comprises the rubber damping body, overcoat, dividing plate and mandrel.Overcoat parcel rubber damping body, dividing plate is embedded in rubber and subtracts body middle part, and mandrel runs through the vertical central axis of rubber damping body and dividing plate, on the mandrel with the bossed stepped part in dividing plate joint, thereby on dividing plate, the shape of cross section of rubber damping body is petal with the mandrel carriage.
The shape of cross section of dividing plate is petal.
Mandrel is a hollow tubular structure.
Overcoat, mandrel and dividing plate are steel structure.
At the surface of contact of mandrel cylindrical and the rubber damping body anti-skidding line of having got on the bus.
The utility model is compared with existing vibration damper and had the following advantages: (1) antitorque anti-deforming ability significantly strengthens.The rubber damping body is designed to the petal shape of symmetry, and at the outer race of the petal-shaped rubber damping body overcoat with steel, the antitorque anti-deforming ability of vibration damper is obviously strengthened.(2) damping property strengthens.Because the antitorque anti-deforming ability of the utility model rubber damping body strengthens, so under the similarity condition, rubber shock absorber thickness of the present utility model can be bigger than the rubber shock absorber thickness of prior art, effectiveness in vibration suppression is better.In addition, petal-like steel baffle design has increased the rigidity of rubber, and replaces rubber to bear partial load, also can obviously strengthen the damping property of vibration damper.

Among the figure, 1, the rubber damping body; 2, overcoat; 3, dividing plate; 4, mandrel; 5, the anti-skidding line on the mandrel cylindrical; 6, the stepped part of mandrel upper process.
Embodiment
Below in conjunction with accompanying drawing the utility model is specifically described.
Fig. 1 is the utility model longitudinal sectional drawing, and as shown in the figure, vibration damper comprises rubber damping body 1, overcoat 2, dividing plate 3 and mandrel 4.Overcoat parcel rubber damping body is with the enabling capabilities and the antitorque anti-deforming ability of Reinforced Rubber damping body.Dividing plate is embedded in rubber and subtracts body middle part, and mandrel runs through the vertical central axis of rubber damping body and dividing plate, on the mandrel with the bossed stepped part 6 in dividing plate joint, thereby with the mandrel carriage on dividing plate, preferred structure is that the shape of cross section of dividing plate is petal.Baffle design has increased the rigidity of rubber damping body, and replaces the rubber damping body to bear partial load, can obviously strengthen the damping property of vibration damper.The shape of cross section of rubber damping body is petal, on the one hand the surface of contact of overcoat and rubber is effectively increased, improve the enabling capabilities of vibration damper, on the other hand, the middle part of petal shape is thick large part, the thick large part of rubber body is dropped at the position that the utility model vibration damper is born load substantially, so effectiveness in vibration suppression is obvious.
Preferred structure is that mandrel is a hollow tubular structure, can save material, and alleviates the weight of vibration damper.
Preferred structure is that overcoat, mandrel and dividing plate are steel structure.
Preferred structure is, at the surface of contact of mandrel cylindrical and the rubber damping body anti-skidding line 5 of having got on the bus, can increase the adhesion of rubber on mandrel, and then reduce the distortion of rubber.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art to some part wherein some changes that may make all embodied principle of the present utility model, belong within the protection domain of the present utility model.
Claims (5)
