Technical field
The present invention relates to a kind of automotive hub shot-blasting machine noise-decreasing device.
Background technology
Automotive hub shot-blasting machine is a kind of impact cleaning device of aluminium alloy wheel hub.It can impose powerful ball blast to the surface of the work of reset condition, removes the rusty scale on it, welding slag and oxide skin, makes it the metallic luster obtaining uniformity, to improve coating quality and the antiseptic effect of steel.Automotive hub shot-blasting machine can produce violent moving when running, thus produces larger noise.Violent vibration not only can cause the fatigue rupture of the structure region of high stress, and it is abnormal that machine and instrumentation can be made to produce, and strong noise hinders one's work the work of personnel and rest, the health of serious shadow staff.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, provides a kind of automotive hub shot-blasting machine vibration and noise reducing damper, can effectively reduce automotive hub shot-blasting machine and produce high vibration, guarantee the normal operation of machine and equipment; Reduce the noise in each cabin, guarantee that staff can normally work and have a rest.Automotive hub shot-blasting machine vibration and noise reducing damper designs for boats and ships internal high temperature, greasy dirt, moist particular surroundings simultaneously, has high temperature resistant, oil resistant, water-fast characteristic.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of automotive hub shot-blasting machine of the present invention noise-decreasing device, it comprises Stainless Steel Shell, acrylonitrile modified EP rubbers is provided with in described Stainless Steel Shell, be inserted with Ni-Ti base goldenrain tree crystal formation memory damping alloy round steel along short transverse in the middle part of described acrylonitrile modified EP rubbers, described acrylonitrile modified EP rubbers inside is embedded with AL-Zn superplasticity damping alloy spring.
Further, described acrylonitrile modified EP rubbers is full of described Stainless Steel Shell.
When boats and ships are applied, Ni-Ti base goldenrain tree crystal formation memory damping alloy round steel one end of vibration and noise reducing damper is welded with Ship Structure, and one end is welded with vibratory equipment.
Ni-Ti base goldenrain tree crystal formation memory damping alloy is a kind of new function material with multiple special mechanical property, and have the characteristic of high damping, it can obtain the attenuation coefficient up to 40%; Have the characteristic of high strength, its yield strength is up to 310MPa; There is memory function, former state can be returned to rapidly after deforming, so utilize Ni-Ti base alloy superelastic effect to design passive energy dissipator.
Ni-Ti base goldenrain tree crystal formation memory damping alloy is applied in equipment vibration and noise reducing damper, both the effect of oscillation damping and energy dissipating can have been played, when can work as again damper generation vibration deformation, the function that Ni-Ti base alloy utilizes it to remember, can make damper return to former state rapidly; Insert the bonding strength that not so Ni-Ti base goldenrain tree crystal formation memory damping alloy cylinder ensure that equipment and hull in the middle of damper, and there is the function of vibration damping;
AL-Zn superplasticity damping alloy spring is the spring utilizing AL-Zn superplasticity damping alloy to process, AL-Zn superplasticity damp alloy material is a kind of high damping material, spiral spring structure itself has shock resistance, vibration-damping function, further increases the damping capacity of AL-Zn superplasticity damping alloy;
Acrylonitrile modified EP rubbers is a kind of high-damping rubber of high temperature resistant, oil resistant.Acrylonitrile modified EP rubbers is used for the connection between equipment and Ship Structure, under this state, equipment is vibration source, the effect of acrylonitrile modified EP rubbers is the vibration of absorption equipment, and the vibration that equipment produces is cut down rapidly by high damping effect, avoid being delivered to above Ship Structure, also can alleviate the vibration of equipment self simultaneously;
AL-Zn superplasticity damping alloy spring combines together with acrylonitrile modified EP rubbers in acrylonitrile modified EP rubbers inside, further increases acrylonitrile modified EP rubbers damping capacity;
The material that the present invention relates to is prior art, and this automotive hub shot-blasting machine vibration and noise reducing damper all has vibration-damping function from materials and structures.
The beneficial effect that the present invention reaches is:
The present invention can effectively reduce automotive hub shot-blasting machine and produce high vibration, guarantees the normal operation of machine and equipment; Reduce noise, guarantee that staff can normally work and have a rest.
