Cov kabmob yog cov khoom uas kho thiab txo qhov coefficient ntawm kev sib txhuam thaum lub sijhawm kis tau tus mob. Kuj tseem tuaj yeem hais tias thaum lwm cov khoom tsim kev txav mus los ntawm tus ncej, nws yog siv los txo qhov coefficient ntawm kev sib txhuam thaum lub sijhawm xa hluav taws xob thiab tswj qhov chaw ruaj khov ntawm qhov chaw nruab nrab ntawm tus ncej. Cov kabmob yog ib qho tseem ceeb hauv cov khoom siv niaj hnub no. Nws lub luag haujlwm tseem ceeb yog txhawb nqa lub cev tig kom txo qhov coefficient ntawm kev sib txhuam ntawm cov khoom siv thaum lub sijhawm kis tau tus mob. Raws li cov khoom sib txawv ntawm kev sib txhuam ntawm cov khoom txav mus los, cov kabmob tuaj yeem faib ua ob hom: cov kabmob dov thiab cov kabmob swb. 1. Muaj lub kaum sab xis sib cuag ntawm lub kaum sab xis sib cuag.pob bearingLub nplhaib thiab lub pob. Lub kaum sib cuag txheem yog 15 °, 30 °, thiab 40 °. Lub kaum sib cuag loj dua, lub peev xwm thauj khoom axial loj dua. Lub kaum sib cuag me dua, nws yog qhov zoo dua rau kev tig ceev ceev. Ib kab bearings tuaj yeem tiv taus radial thiab unidirectional axial loads. Structurally, ob kab ib kab angular contact pob bearings nrog kev sib xyaw ua ke rov qab sib koom sab hauv thiab sab nraud rings, uas tuaj yeem tiv taus radial thiab bidirectional axial loads. Kev siv tseem ceeb ntawm angular contact pob bearings: ib kab: tshuab cuab yeej spindle, high-frequency motor, roj turbine, centrifugal separator, lub tsheb me me pem hauv ntej log, differential pinion ncej. Ob kem: roj twj tso kua mis, Roots blower, cua compressor, ntau yam kis tau tus mob, roj txhaj twj tso kua mis, luam ntawv tshuab. 2, Lub pob bearings tus kheej-aligning muaj ob kab ntawm cov hlau pob, thiab qhov sib tw sab nraud yog ntawm lub pob sab hauv hom nto. Yog li ntawd, nws tuaj yeem kho qhov tsis sib xws ntawm lub ncej los ntawm kev khoov lossis tsis concentricity ntawm lub ncej lossis plhaub. Lub tapered qhov bearing tuaj yeem ntsia tau yooj yim rau ntawm lub ncej los ntawm kev siv fasteners, feem ntau yog bearing radial loads. Cov kev siv tseem ceeb ntawm cov kabmob pob uas sib dhos ua ke: cov tshuab ua haujlwm ntoo, cov tshuab xa xov, cov kabmob ntsug uas sib dhos ua ke. 3, Cov kabmob sib dhos ua ke Cov kabmob no muaj cov menyuam kheej kheej ntawm lub nplhaib sab nraud ntawm txoj kev sib tw thiab lub nplhaib sab hauv ntawm txoj kev sib tw ob chav. Raws li cov qauv sab hauv sib txawv, nws tuaj yeem muab faib ua plaub hom: R, RH, RHA, thiab SR. Vim yog qhov sib xws ntawm qhov chaw nruab nrab ntawm txoj kev sib tw sab nraud thiab qhov chaw nruab nrab ntawm cov kabmob, nws muaj kev ua tau zoo sib dhos. Yog li ntawd, nws tuaj yeem kho qhov tsis sib xws ntawm lub axis los ntawm kev hloov pauv lossis tsis sib xws ntawm lub qhov lossis lub plhaub, thiab tuaj yeem tiv taus qhov tsis sib xws ntawm radial.
