Abstract
The invention discloses a vibration absorber and relates to the technical field of generator sets, in particular to the field of the structure of vibration absorbing devices. The vibration absorber comprises a bowl-like stainless steel upper cover, wherein the top part of the stainless steel upper cover is a sealed end, the bottom part of the stainless steel upper cover is an open end, an axial through hole is reserved in the center of the top part of the stainless steel upper cover, a nut is fixed in the through hole, and the nut is welded on the inner side of the top part of the stainless steel upper cover; and the inner wall of the stainless steel upper cover is fixed with a frustum-shaped rubber vibration absorbing layer, a trumpet-shaped stainless steel base is fixed in the rubber vibration absorbing layer, the bottom part of the stainless steel base has an annular plane, and at least two base mounting holes are formed on the annular plane. The stainless steel upper cover of the vibration absorber is fixed on a generator supporting leg of a diesel engine supporting leg by a bolt, and the stainless steel base is fixed on a chassis mounting frame by a bolt. The vibration absorber is mounted according to each vibration source to reduce low-frequency noises effectively, thereby reducing damages to environment and human bodies. The vibration absorption effect of the vibration absorber is that the intensity of the noises is reduced from the original 85db to 75db. And when the ground is uneven, the displacement can be reduced.
Description
Technical field
The present invention relates to the technical field of generating set, relate in particular to the structure field of damping device.
Background technology
Every noise all can produce harm to human body, and noise roughly is divided into: high frequency noise, mid-frequency noise, low-frequency noise.Wherein low-frequency noise more can produce long-range influence to health, and still, the harm that present this low-frequency noise produced does not also obtain the enough attention of people.The damping device of present existing generating set is the hard connection taked (directly connecting), does not have effective glissando, and what have just installs the easy rubber skin of one deck additional, and up to the present the low-frequency noise that produces is not effectively controlled.
Summary of the invention
The objective of the invention is provides a kind of vibration absorber of good damping effect in order to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this: a kind of vibration absorber, comprise bowl-shape stainless steel upper cover, the top of stainless steel upper cover is that blind end, bottom are openend, the top center of described stainless steel upper cover is provided with axially extending bore, through hole internal fixation nut, described nut is welded on the inside top of stainless steel upper cover; The inwall of described stainless steel upper cover is taper type rubber shock-absorbing layer fixedly, rubber shock-absorbing layer internal fixation is tubaeform stainless steel base, and the bottom of stainless steel base is the plane ringwise, and at least two base installing holes are set on described planar annular.
The stainless steel upper cover of vibration absorber is by being bolted on generator leg or the diesel engine leg, the stainless steel base is by being bolted on the installing rack of chassis, at each focus mounting shock absorber, effectively reduce low-frequency noise, thereby give the minimizing harm of environment and human body.Effect: from before 85 decibels be reduced to 75 decibels.And when the out-of-flatness of ground, can reduce displacement.
For make the stainless steel base more firm, stably be installed on the installing rack of chassis, the base installing hole is four.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 be among Fig. 1 A to view.
Embodiment
As shown in Figure 1, 2, be a kind of vibration absorber, comprise bowl-shape stainless steel upper cover 1, the top of stainless steel upper cover 1 is that blind end, bottom are openend, the top center of stainless steel upper cover 1 is provided with axially extending bore 4, through hole 4 internal fixation nuts 5, and nut 5 is welded on the inside top of stainless steel upper cover 1.The inwall of stainless steel upper cover 1 is taper type rubber shock-absorbing layer 2 fixedly, rubber shock-absorbing layer 2 internal fixation are tubaeform stainless steel base 3, and the bottom of stainless steel base 3 is the plane ringwise, and four base installing holes 6 are set on the planar annular of stainless steel base 3.
Claims (2)
1. vibration absorber, it is characterized in that: comprise bowl-shape stainless steel upper cover, the top of stainless steel upper cover is that blind end, bottom are openend, and the top center of described stainless steel upper cover is provided with axially extending bore, through hole internal fixation nut, described nut is welded on the inside top of stainless steel upper cover; The inwall of described stainless steel upper cover is taper type rubber shock-absorbing layer fixedly, rubber shock-absorbing layer internal fixation is tubaeform stainless steel base, and the bottom of stainless steel base is the plane ringwise, and at least two base installing holes are set on described planar annular.
