Hybrid Bearings
Taw qhia
Hybrid bearings muaj rings ua los ntawm cov kabmob steel thiab cov khoom dov ua los ntawm cov kabmob qib silicon nitride (Si3N4), uas ua rau cov kabmob hluav taws xob insulating.
Silicon nitride dov cov ntsiab lus tuaj yeem txuas ntxiv kev pabcuam lub neej los ntawm kev muab cov kabmob ua kom zoo dua qub, txawm tias nyob rau hauv kev ua haujlwm nyuaj.
Kev thov ncaj qha tshaj plaws ntawm silicon nitride hauv cov kabmob yog ua cov kabmob sib xyaw.Lub pob lossis cov menyuam yog cov khoom siv silicon nitride, thiab cov kabmob nrog lub nplhaib sab hauv thiab sab nrauv ua los ntawm cov hlau yog hu ua hybrid bearing.Raws li lub pob lossis lwm cov menyuam ntawm hybrid bearing, daim ntawv thov kev lag luam ntawm silicon nitride yog loj hlob.Cov lus hauv qab no teev cov txiaj ntsig thiab kev siv tshwj xeeb ntawm silicon nitride ceramic ua cov khoom siv.Thaum silicon nitride hnav, nws qhia tau hais tias cov yam ntxwv zoo sib xws rau cov kabmob steel, uas yog, nws spalling los tsim cov ntsiab lus pitting, tsis yog ua kom tawg tag, thiab kev sib txhuam tsis kam nce thiab suab nrov, tab sis cov kabmob tseem tuaj yeem khiav. los yog txawm tias qhuav qhuav, nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj rau cov khoom, nws tseem tuaj yeem ua haujlwm thiab ua tau zoo thaum muaj xwm txheej ceev.
Qhov zoo
● Kev tiv thaiv los ntawm hluav taws xob puas tsuaj
Hybrid bearings yog non-conductive thiab yog li tsim nyog rau daim ntaub ntawv xws li AC thiab DC motors thiab generators, uas muaj hluav taws xob tam sim no.
● Muaj peev xwm ceev dua
Qhov ceev ntawm silicon nitride dov lub caij yog 60% qis dua ib qho me me dov lub caij ua los ntawm cov kabmob steel.Qhov hnyav qis thiab inertia txhais ua kom muaj peev xwm ceev dua thiab tus cwj pwm zoo dua thaum pib thiab nres.
● Lub neej ua haujlwm ntev
Kev sib txhuam qis qis tsim nyob rau hauv hybrid bearings, tshwj xeeb tshaj yog nyob rau hauv high speeds, pab txhawb nqa kev pab cuam lub neej ntev thiab ncua sij hawm relubrication.
● Siab hnav-tiv taus
Silicon nitride dov cov ntsiab lus muaj qib siab dua ntawm hardness ua hybrid bearings tsim nyog nyob rau hauv cov xwm txheej nyuaj thiab qhov chaw muaj kab mob.
● Cov kabmob siab nruj
Nrog lub siab modulus ntawm elasticity, hybrid bearings muab cov kabmob muaj zog ntxiv.
● Txo kev pheej hmoo ntawm smearing
Txawm tias nyob rau hauv lub lubrication tsis txaus, xws li kev kub ceev thiab ceev acceleration, los yog qhov twg muaj ib tug tsis txaus hydrodynamic zaj duab xis, qhov kev pheej hmoo ntawm smearing yog txo ntawm silicon nitride thiab steel nto.
● Txo txoj kev pheej hmoo ntawm kev tsis tseeb brinelling
Thaum raug kev vibration, hybrid bearings tsis tshua muaj kev cuam tshuam rau kev dag brinelling (tsim muaj kev nyuaj siab nyob rau hauv txoj kev sib tw) ntawm silicon nitride thiab steel nto.
● Tsawg rhiab heev rau qhov kub thiab txias gradients
Silicon nitride dov cov ntsiab lus muaj qis coefficient ntawm thermal expansion, uas txhais tau hais tias lawv ruaj khov dua kub gradients nyob rau hauv lub bearing thiab muab ntau dua preload / clearance tswj.
Daim ntawv thov
Hauv kev lag luam kev lag luam, silicon nitride ceramics tuaj yeem siv los ua turbine blades, mechanical seal rings, high temperature bearings, high-speed cutting tools, moulds ruaj khov, thiab lwm yam. Kev ntseeg siab thiab kev pabcuam lub neej ntawm cov khoom siv no cuam tshuam zoo heev vim corrosion ntawm cov hlau. .Txawm li cas los xij, cov khoom siv silicon nitride ceramic muaj kev hnav zoo heev, kev tiv thaiv corrosion thiab kub thermal poob siab, uas tuaj yeem siv rau hauv kev lag luam tshuab tsis siv cov khoom siv hlau.
