Spline?shaft is a kind?of mechanical transmission,?the?key to peace,?circle half?key,?oblique key?role,?all?is the transmission of mechanical?torque,?can?keep?axis synchronous rotating.
A?quenching?test
For a long time,?shaft?splines?are?high-frequency quenching process?to?quench oil,?but?oil quenching and?high costs,and because of?the physical characteristics of the oilcooling?is slow,?the workpiece?will take a long time toreach the effect.?But with the?high frequency?quenchingmachine,?not only by?water instead of?the?high?cost of oil,and?heating?and?cooling speed,?speed?is?very fast,?has greatly increased the?manufacturers?benefit.
Two?rapid?cooling?would affect?the spline shaft?deformation
In general,?a cooling medium?speed?more quickly?formed?a greater stress,?resulting in?hardened gear?deformation andcracking?tendency.?But in?time,?we test,?spline shaftadopts water cooling?water?cooling?quenching.?Part of the austenite?transformation of?cooling speed?not?to?martensite transformation?decrease.?Force and?resistance stressrelieving?effect?on?part of?air cooling?water-cooling?heat of formation,?it?can be fully guaranteed to increase theshaft?hardness,?reduce the amount of deformation,?the induction heating?equipment technical?requirements.
Three compared?carburizing furnace,?resistance furnace,what advantage
We in Henan?super?Feng electrical equipment?limitedfunding,?the?model for the WH-VI-80KW?models and?80KWresistance furnace and?80KW?carburizing furnace,?the?heat treatment?compared.?It was concluded that the?high frequency?furnace,?heating speed?is?about 2 times as much as the?other?two,?the hardness testing?found that,?almostnot much difference between,?so?that,?high frequency furnace?can be more?time and energy saving,?environmental protection and energy saving,?is the first choice?of a large factory.
