Electromagnetic clutch maintenance The electromagnetic clutch must be cleaned before installation，Remove anti-rust grease and debris。The electromagnetic clutch can be mounted coaxial，Shaft mounting is also possible，The axis must be fixed，The active part and the driven part are not allowed to have axial movement，When installing the shaft，The coaxiality between the active part and the driven part axis should not be greater than0.lmm。When wet electromagnetic clutch is working,Must lubricate between the friction plates
Measures to control deformation are put forward，If using rotary quenching、Die quenching、Control parts into the oil mode, etc，The potential to swing materials；On the other hand, it is to improve the automation level and stability of heat treatment，The stability of the optimized process is fully guaranteed，The dispersion of product quality is very small（OR-zero）goal，A special post-carbonitriding quenching is performed，Increase the content of residual austenite，Improve the state of external stress，The carbonitriding of gearbox is greatly improved，The residual austenite content was increased without reducing the surface hardness，Grinding technique、Linear survey
（one）、The main functions of the cage are： a、Separate each rolling element，Minimize friction and heat generation in the work； b、Keep the distance between rolling elements equal，Distribute the load evenly； c、detachableSKFBearings and inner and outer rings can swing each otherSKFThe rolling element of the bearing will not fall out； d、inSKFBearing non-load zone guide rolling element。 （two）、SKFbearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]bao
Use scrollSKFVarious mechanical devices of bearings、The performance of instruments and other market requirements are becoming more stringent，towardsSKFBearing required condition、Performance is also increasingly diverse。In order to be able to from a large number of structures、In size，Choose the best fitSKFbearing，It needs to be studied from various angles。In choosingSKFbearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]when，normal，test
It is best not to use worn or damaged in your vehicleINAbearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]，Because this may bring you unsafe factors during the driving process，In severe cases, it can cause life-threatening injuries。So in the use of flat bearings[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing
Silicon nitride ceramicsNSKBearing rings and rolling parts are made of silicon nitride（Si3N4）Ceramic material，The retainer uses teflon（PTFE）As standard，It can also be used in generalRPA66-25，PEEK，PI，And phenolic cloth bakelite pipe and so on。SiN4Full ceramicNSKImported bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]By comparisonZrO2
The size of working clearance will directly affect its working performance and service life，Working clearance is subject to centrifugal force、Manufacturers and users mostly manufacture and select bearings according to radial clearance[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]．As clearance refers to linear bearings[Linear bearing:Linear bearing，ytpLinear bearing，]Clearance in steady operation。Proper working clearance will help
Calculate the safety factor of static loadFsHelps to determine the selected bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]Whether it has sufficient static load rating。 FS=CO/PO amongFSStatic load safety factor，COStatic load rating[KN]，POEquivalent static load[KN] Static load safety factor
1.Use reasonable cooling methods： The influence of the cooling process on the deformation of metal after quenching is also a very important cause of deformation。Hot oil quenching has less deformation than cold oil quenching，Generally controlled in100±20℃。The cooling capacity of the oil is also critical to deformation。The mixing method and speed of quenching affect the deformation。The faster the metal heat treatment cooling speed，The more uneven the cooling，The greater the stress generated，Die of variable bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，I
