introduction：Vibration on powder metallurgy bearings[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The damage is very sensitive，exfoliation、impression、corrosion、crack、Wear and tear will be reflected in the bearing vibration measurement，therefore，By using a special bearing vibration gauge(Frequency analyzer)The magnitude of the vibration can be measured，No anomalies can be inferred from the frequency division

introduction：Draw mold structure drawing one、When the finished drawing is transferred into the mold drawing，The finished drawing must be multiplied and shrunk。（Die size=Product size×shrink）Must put the finished drawingMIRROR（Mirror shooting）once，That is, the finished drawing in the mold circle is antiimage（Except when the finished product is perfectly symmetrical）In front mold，Lines that do not belong to the front mold should be deleted from the back mold，Lines that do not belong to the back mold should be removed。 two、The finished product should follow the principle of separation in the mold，Especially symmetrical，If the finished product is not divided，It is possible to make mistakes on arrival at the shop。 three、Molds for all pillow positions，The occipital position must avoid entering the water，Add a nozzle iron if you cant avoid it。

introduction： Its not diesel. It doesnt rust,Diesel contains too much water.In addition,Do not use strong acid and alkali chemicals to cleanNSKbearing[NSKbearing:Seiko Co., LTD（NSK LTD.）Be established in1916years，It is the first manufacturer to design and produce bearings in Japan。NSKThe function of the bearing fit is to makeNSKThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together，Thus, the load is transferred in the rotating state and the motion system is limited relative to static

introduction： Large forgings because of their large size，Many processes，Period length，The process is not uniform，There are many unstable factors，Therefore, it often causes serious uneven tissue properties，Resulting in mechanical properties testing，Metallographic tissue examination and nondestructive testing can not pass。 Due to the segregation of the chemical composition in the ingot，Inclusion accumulation，The effect of various porosity defects；The temperature changes slowly when heating，Unevenly distributed，High internal stress，More defects；High temperature and long forging time，Local stress local deformation，Plastic flow regime、Degree of compaction、The deformation distribution varies greatly；The diffusion process is slow during cooling，Complex tissue transformation，Large additional stress。

introduction：At high speed、Under high temperature conditions，NSKImported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]Oil lubrication can be used when the grease lubrication is no longer suitable。Through the circulation of lubricating oil，It takes away a lot of heat。Viscosity is an important characteristic of lubricating oil，The size of the viscosity directly affects the fluidity of the lubricating oil and the thickness of the oil film formed between the friction surfaces，The viscosity of lubricating oil at the operating temperature of the bearing is generally12-15cst。The higher the speed, the lower the speed
