Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
As shown in Figures 1 to 4, the invention provides a kind of axle sleeve vibration damper, comprise rubber axis body 10, packer ring 20 and metal shell 30, rubber axis body 10 has the axis hole 11 passed for outer coupling shaft, the outer circumferential face of rubber axis body 10 is provided with the circular groove 12 extended along its circumference, packer ring 20 is embedded in circular groove 12, and the bottom surface of the inner peripheral surface of sealing rubber ring 20 and circular groove 12 separates to form annular pass, be filled with damp liquid 70 in this annular pass, metal shell 30 is wrapped on rubber axis body 10 and packer ring 20.
Pass through technique scheme, when being arranged on the outer coupling shaft (not shown) in axis hole 11 and medium and low frequency vibration occurring, axle sleeve vibration damper is subject to the squeezing action of outer coupling shaft and load and produces distortion, damp liquid 70 is flowed back and forth in circular groove 12, damp liquid 70 produces with the wall of circular groove 12 and the inner peripheral surface of packer ring 20 and rubs, be heat by kinetic transformation, thus dissipation vibrational energy, realize the damping effect of low and medium frequency scope.
Preferably, ventilation flue 14 is formed in rubber axis body 10, this ventilation flue 14 extends to the inwall of axis hole 11 from the bottom surface of circular groove 12, axle sleeve vibration damper also comprises High-frequency absorber part 50 and vibration film 60, the inner that vibration film 60 is arranged on ventilation flue 14 is sentenced and circular groove 12 and ventilation flue 14 is separated, High-frequency absorber part 50 is arranged in circular groove 12 and contiguous vibration film 60 is arranged, and High-frequency absorber part 50 has the multiple mesh 511 allowing damp liquid to pass.The ventilation flue 14 herein mentioned " the inner " refers to one end of the close circular groove 12 of ventilation flue 14, and " outer end " of ventilation flue 14 mentioned below refers to one end of the close axis hole 11 of ventilation flue 14.
In this case, when outer coupling shaft generation dither, damp liquid 70 can not flow because vibration frequency is too high in circular groove 12, shake among a small circle can only be produced, the vibration wave of damp liquid 70 can cause vibration film 60 to vibrate, and (during vibration wave crest, damp liquid promotes vibration film 60; During vibration wave trough, vibration film 60 resets, again damp liquid is squeezed and go back), because High-frequency absorber part 50 is arranged near vibration film 60, therefore damp liquid is made to flow back and forth in the both sides of High-frequency absorber part 50, cause the friction of damp liquid and mesh wall, thus vibrational energy is converted into heat, realize the effect of High-frequency absorber.Further, the outer end of ventilation flue 14 and air communication, effectively can regulate the pressure in ventilation flue 14, prevents the vibration affecting vibration film 60 because pressure is excessive.Meanwhile, the air flowing that vibration film 60 can be utilized to vibrate cause is lowered the temperature to axle sleeve vibration damper, and can utilize air friction that vibrational energy is converted into heat energy to be dispersed in air.
Conveniently shaping, preferably, ventilation flue 14 can extend along the radial direction of rubber axis body 10.
In order to improve the High-frequency absorber performance of axle sleeve vibration damper further, preferably, as shown in Figure 4, multiple ventilation flue 14 is formed in rubber axis body 10, the plurality of ventilation flue 14 is arranged along the circumferential interval of rubber axis body 10, is provided with vibration film 60 and High-frequency absorber part 50 at the inner place of each ventilation flue 14.
Particularly, axle sleeve vibration damper of the present invention also comprises the metal lining 40 be arranged in axis hole 11, and the side opening of this metal lining 40 is provided with the through hole 41 be communicated with ventilation flue 14, is communicated with ambient air to make ventilation flue 14.Rubber axis body 10 has been embedded in metal frame 80, to improve the rigidity of axle sleeve vibration damper.
In axle sleeve vibration damper of the present invention, High-frequency absorber part 50 can have various suitable structure, such as, can be mesh plate structure.Conveniently install, preferably, as shown in Figure 2, High-frequency absorber part 50 is formed as the box like structure be located on the inner of ventilation flue 14, this box like structure comprises base plate 51 and is formed in the side plate 52 around this base plate 51, side plate 52 extends from the edge-perpendicular of base plate 51 in base plate 51, be connected to the edge seal of side plate 52 inner around.Described box like structure can be such as square box shape structure or circular box like structure.
In this case, multiple mesh 511 can all be arranged on base plate 51, also can all be arranged on side plate 52, and can also a part be arranged on base plate 51, another part be arranged on side plate 52, and the present invention is not restricted this.Vibration film 60 can be connected on High-frequency absorber part 50, on the inner that also can be connected to ventilation flue 14 or inwall, as long as damp liquid 70 can be stoped to enter in ventilation flue 14.
Preferably, the periphery of vibration film 60 is connected on High-frequency absorber part 50, like this when assembling, High-frequency absorber part 50 and vibration film 60 integrally can be installed on rubber axis body 10, thus convenient for assembly.
Particularly, as shown in Figures 2 and 3, multiple mesh 511 are arranged on the central authorities of base plate 51, that is, the middle section of base plate 51 is formed as mesh area, vibration film 60 is positioned at the side towards ventilation flue 14 of base plate 51, and the periphery of vibration film 60 is connected to the surrounding of described mesh area, when outer coupling shaft generation dither, damp liquid flows back and forth in the both sides of base plate 51 under the effect of vibration film 60, produce with the hole wall of mesh 511 and rub, dissipation vibrational energy.In other embodiments, the periphery of vibration film 60 can be connected on side plate 52.
Preferably, as shown in Figure 4, the bottom surface of circular groove 12 is provided with the first groove 13, High-frequency absorber part 50 arranges on the bottom surface of the first groove 13, ventilation flue 14 extends to the inwall of axis hole 11 from the bottom surface of the first groove 13, the inner peripheral surface of packer ring 20 is formed with the sealing block 21 corresponding with the first groove 13 position, under the not extruded state of axle sleeve vibration damper, the bottom surface of sealing block 21 and the first groove 13 separates.In this situation, sealing block 21 plays the function being similar to piston, coupling shaft produces medium and low frequency vibration outside, when axle sleeve vibration damper is squeezed, sealing block 21 moves towards the bottom surface of the first groove 13, thus the damp liquid in extruding the first groove 13, cause damp liquid to flow in circular groove 12.
