Description
Technical field
The present invention relates to a kind of circular ring type optical elastohydrodynamic oil films to measure testing machine, cylinder under the weary oily operating condition of especially a kind of high speed
The measurement testing machine of roller elasto-hydrodynamic lubrication for line contacts oil film thickness and oil film shape.
Background technique
In modern mechanical industry, the failure of the machine components such as bearing, gear is often caused by elastohydrodynamic lubrication failure.
In particular with the progress of modern technologies, bearing, gear etc. constantly develop to high speed direction, and weary oil phenomenon is more and more.Therefore
Elastohydrodynamic lubrication under oil operating condition weary to high speed carries out theoretical and experimental study, and explaining influences elastohydrodynamic lubrication
Factor have great importance.
Determine that the geometric shape of oil film and thickness in contact zone are one of the mostly important problems of elastohydrodynamic lubrication research, because
The degree of closeness of micro-bulge in relative motion surface is decide for oil film thickness, to lose to the friction of system, abrasion and fatigue
Effect plays overriding effect.From the method for measurement contact area film thickness, other than optical interferometry, the side of oil film is measured
There are also electric-resistivity method, capacitance method, magnetoresistance method, displacement method and x-ray methods etc. for method.
In bullet stream film thickness measuring technology, electric-resistivity method is the technology used earliest, but further opening with research work
Exhibition, people gradually have found that contact zone can only be measured by electric-resistivity method that whether there is or not oil films without measure thickness.The principle of capacitance measurement and
Electric-resistivity method is similar, and capacitance method can judge film thickness according to the size for measuring capacitor, but a disadvantage is that capacitance measurement is oil film
Average thickness, rather than the actual value at any position.Magnetoresistance method is to pass through oil film by measurement magnetic flux to cause electricity in coil
Rheology calculates oil film thickness, and this measurement method is easy by external interference.Displacement method be by measuring limit displacement come
The method for indirectly determining oil film thickness, this method depend on the levels of precision of displacement sensor, at present displacement sensor
Minimum detectability is 0.1 micron, and the thickness of usually oil film is less than 0.1 micron, therefore displacement method has significant limitation.X is penetrated
Collimation method is lubricant film thickness to be measured the difference of metal and oil plant penetration power according to X-ray, but find X by studying for a long period of time
Ray method is relatively difficult in calibration, and can only generally measure the minimum value of oil film thickness.
Shape using the film thickness of optical interferometry measurement bullet stream contact position be start the 1960s to use it is a kind of compared with
New technology.In recent years due to the attention of optical interferometry measuring device and technology continuously improved increasingly by researcher.
Optical interferometry principle is simple, is easy to implement, can measure the thickness of contact zone oil film and the shape of oil film simultaneously.Optical interferometry
Most important means of the method as measurement film thickness, precision have also reached 1 ran.Although optical interference measuring method has obtained very much
Approve, but interference of light measuring of oil film device type is fewer.Nowadays line contact interference of light measuring of oil film device is divided into substantially
Two kinds, the first is disc type light-interference measuring apparatus, and disc type light-interference measuring apparatus, which can only measure, can only use taper roller
As test specimen, such measuring device has certain limitation to roller taper and length, and it is even more impossible to measure the line of cylindrical roller
Contact oil film thickness.Another kind is linear reciprocating light source interference experiment platform, and although this experimental bench is capable of measuring cylindrical roller, still
Due to it is to be moved back and forth the characteristics of, can only be run in low speed, have certain limitation.
