Abstract

A vibration isolator for lateral and axial isolation, as the case may be, of vibrations between inner and outer elements, such elements having a space therebetween with leaf spring packs and hydraulic fluid therein and hydraulic fluid passages for moving hydraulic fluid opposite sides of such leaf spring packs for dampening vibration between such elements.

Description

Use the lateral vibration isolators of leaf spring
The present invention relates to the lateral vibration isolators of running shaft.
In many rotary-type machineries, axle is supported by bearings with rolling contact.,, be used in the industry at large so their cost is very low because thereby bearings with rolling contact realization standardization can be produced on a large scale.But their major defect is them lacks damping force.In order to relax this defective, adopted the squeeze film vibration damper so that for they increase necessary extra damping force.The squeeze film vibration damper is made up of outer and inner circular element and the thin fluid film that is positioned between the two.But, different with shaft bearing, circular element can not rotate in it.Because the heat that produces in thin fluid film, the squeeze film vibration damper needs an oil circulating system.Oil circulating system requires to have oil supplying, extracts and filtrating equipment.Therefore make the squeeze film vibration damper realize that standardization and mass production are difficult.Their assembling also is very difficult.
In the design of rotary-type machinery, the dynamic characteristic of analyzing this system is very important.In order to obtain the bigger coefficient of stability, promptly the coefficient of stability estimated of the degree that departs from according to service speed and critical velocity has carried out the rigidity of running shaft or block bearing and has regulated test.Be difficult for carrying out because the rigidity of running shaft is regulated, all be ready to carry out the rigidity adjusting of block bearing.But control the rigidity of bearings with rolling contact and be not easy.The squeeze film vibration damper has only been introduced damping force, makes their rigidity of control difficult equally.In addition, the dynamic characteristic of squeeze film vibration damper is non-linear, and their damping force can reduce suddenly on undesired ground.But the rigidity of lateral vibration isolators of the present invention and damping force are control easily.Their dynamic characteristic is linear.
The present invention uses the purpose of the lateral vibration isolators of leaf spring to be to overcome the above-mentioned shortcoming of traditional squeeze film vibration damper.Use isolator of the present invention, rigidity and damping force be control easily all.They are without any need for accessory or device, thereby might make their realize standardization and carry out mass production.They also may be used to be controlled at the nonrotational type structural vibrations in the hot environment, for example pipe-line system in electric power or chemical plant effectively.Because the structure of isolator of the present invention is small and exquisite, their installment work can be finished very soon.
Lateral vibration isolators of the present invention also can be used for the non-rotating structure as pipe and so on.For example, power station or chemical plant have a lot of pipe-line systems.When in the fluid flow ipe of heat, vibrate sometimes.For the vibration of controlling pipe can be used the stiffener that is made of the steel disc spring.But their damping force is minimum.Because the high temperature of hot fluid, the rubber stiffener is out of use.Lateral vibration isolators of the present invention can be used in the hot environment and have very strong damping force.
The vibration insulator of use leaf spring is at first invented by Austrian doctor Geislinger during World War II and is used to control torsional vibration.The torsional vibration isolator of use leaf spring is used for the torsional vibration damper and the connector of internal-combustion engine.Their performance has been established fully through whole world application nearly 35 years since they are by invention first and is confirmed.
Below in conjunction with accompanying drawing the embodiment of the invention is elaborated, wherein:
Fig. 1 is inner section figure of the present invention.
Fig. 2 is a side cross-sectional, view of the present invention.
Fig. 3 is an isolator of the present invention of being furnished with bearings with rolling contact.
Component names among Fig. 1 to 3 is as follows:
1: interior ring 7: oil groove
2: outer shroud 8: oily ebb interval
3: leaf spring 9: seal element
4: middleware 10: clamping element
5: inner fluid space 11: oily feed-in hole
6: lid
As illustrated in fig. 1 and 2, lateral vibration isolators of the present invention is made of a plurality of leaf spring laminations and fluid therebetween.Interior ring is flexibly being supported by the leaf spring of device on circumference.Supporting force is by the quantity of leaf spring, physical dimension (being thickness, width and length) and material, and the quantity of leaf spring lamination determines.Because its yielding support power can be controlled, thus be installed in the critical velocity of the machinery on the vibration insulator of the present invention also can be controlled soon.When critical velocity when being controllable, the stability of machinery can be improved by the mode that critical velocity and service speed are departed from.
The relatively move volume-variation that causes the inner fluid space and the fluid of ring passes oil groove among Fig. 2 (7) and flows among Fig. 1, thereby produces damping force.Damping force can be by the viscosity of fluid, and the size of friction factor and oil groove is controlled.In lateral vibration isolators of the present invention, rigidity and damping force at the bearing position place are control easily, and can obtain a bigger damping force.The damping force that result of theoretic analysis demonstrates isolator of the present invention is equal to or greater than the damping force of squeeze film vibration damper and fluid film bearing.Also demonstrating in vertical direction, there are not the cross-couplings relation in rigidity and damping force.Not having the cross-couplings relation is exactly the steady dynamic step response that means isolator of the present invention.
As shown in Figure 2, the inner fluid space is very big and sealed by lid and seal element, thereby no longer needs extra oil circulating system.Therefore, the standardization of isolator of the present invention and mass production may just become.
A typical example is presented among Fig. 3, and isolator wherein of the present invention disposes a bearings with rolling contact.Though isolator of the present invention disposes bearings with rolling contact usually, itself also can be used alone as a kind of fluid film bearing.When the interior ring among Fig. 1 or axle when beginning to rotate, between interior ring and leaf spring, can produce hydrokinetic pressure, therefore, the lubricating liquid film of generation is separated from each other them.Use the bearing of lubricating liquid film and leaf spring simultaneously, as shown in Figure 3, have bigger damping force and good vibration characteristics.In isolator of the present invention, can not occur in the labile oily vortex of a kind of typical case who occurs in some fluid film bearing.
