Hmoov metallurgy roj bearing yog cov siv dav tshaj plaws Roj-impregnated bearing tes tsho hmoov metallurgy nias qhov chaw. Lub tes tsho ncej ua los ntawm kev npaj hmoov, molding, sintering, roj immersion thiab lwm yam txheej txheem tseem ceeb yog hu ua hmoov metallurgy roj bearing.
Nta ntawm hmoov metallurgy roj-impregnated bearings
1. Haum rau kev tsim khoom loj.
2. Tsis tas yuav txiav, cov khoom txuag, thiab tus nqi qis.
3. Lub suab nrov qis dua li ntawm cov kabmob dov.
4. Lubricating roj tsis yog muab, los yog roj nkag los ntawm lub tes tsho phab ntsa.
5. Tus nqi ntawm cov pwm yog siab thiab nws tsis haum rau me me-batch ntau lawm.
6. Tsawg mechanical zog.
7. Tsawg coefficient ntawm kev sib txhuam.
Cov khoom siv los ua cov bushing no hu ua hmoov metallurgy antifriction khoom. Hmoov metallurgy cov ntaub ntawv los tiv thaiv kev sib txhuam yog muab faib ua peb hom: hlau-raws li, tooj liab-based, thiab aluminium-based. Cov hlau-raws li hmoov metallurgy cov khoom siv los tiv thaiv kev sib txhuam yog cov hlau, thiab qee zaum me me ntawm tooj liab ntxiv los txhim kho cov ciam teb lubrication kev ua tau zoo. Nws yog tus cwj pwm los ntawm lub zog siab thiab tus nqi qis, tab sis cov kabmob muaj kev sib txhuam tsis zoo thiab yuav xeb. Nws tsuas yog tsim nyog rau qee lub sijhawm ceev ceev, thiab lub taub hau taub yuav tsum tau quenched. Copper-based hmoov metallurgy cov khoom siv los tiv thaiv kev sib txhuam yog feem ntau yog tooj liab, ntxiv 6% ~ 10 feem pua tin, ib qho me me ntawm zinc, thiab txhuas. Nws yog yam ntxwv los ntawm tsis muaj xeb, ruaj khov bearing kev ua tau zoo nyob rau hauv nruab nrab ceev thiab lub teeb load, tab sis tus nqi yog siab; txoj kev loj hlob ntawm txhuas-raws li hmoov metallurgy los tiv thaiv kev sib txhuam cov ntaub ntawv yog kuj lig, thiab nws yog yus muaj los ntawm tus nqi qis thiab nruab nrab lub zog, tab sis tsis zoo hnav tsis kam thiab adhesion kuj.
Roj-impregnated bearings tseem hu ua porous bearings, uas yog los ntawm lub xeev ntxeem tau ntawm cov kabmob nws tus kheej. Roj-impregnated bearings yog sintered lub cev ua los ntawm hlau hmoov thiab lwm yam khoom los ntawm hmoov metallurgy. Roj-impregnated bearings tsis yog tsuas yog ntxeem tau xwb tab sis tus naj npawb, qhov loj, thiab cov duab ntawm lub qhov hws kuj tuaj yeem tswj tau thiab hloov kho thaum lub sijhawm tsim khoom, uas muaj cov qib siab ntawm kev ywj pheej thiab kev ywj pheej.
Cov qauv ntxeem tau ntawm cov roj-impregnated bearing enables nws nqus lubricating roj zoo heev. Tom qab cov roj-impregnated bearing yog impregnated nrog 10 feem pua rau 40 feem pua cov roj lubricating, nws tuaj yeem lubricate nws tus kheej thaum lub sijhawm ua haujlwm ntawm cov khoom siv. Daim ntawv thov ntawm cov roj-impregnated bearings muaj qhov pom tseeb ntawm cov cuab yeej siv tshuab uas khiav mus ntev thiab nyuaj rau kev tuav lub xeev lubricated.
Lubrication txoj cai ntawm roj bearing
Tom qab cov roj-impregnated bearing yog impregnated nrog lubricating roj thiab muab tso rau hauv lub lag luam, qhov kub ntawm cov roj-impregnated bearing yuav nce raws li nrog kev sib txhuam thiab kub ntawm cov khoom siv kho tshuab. Txij li thaum lub expansion coefficient ntawm cov roj yog siab tshaj ntawm cov hlau, lub lubricating roj nyob rau hauv cov roj impregnated bearing yuav cia li nkag mus rau lub lubricating nto los lubricate cov kabmob. Thaum cov cuab yeej siv tshuab tsis ua haujlwm, qhov kub ntawm cov roj impregnated bearing yuav poob, thiab cov roj lubricating yuav nqus rov qab rau hauv lub qhov hws.
Roj-impregnated bearings siv cov yam ntxwv ntxeem tau ntawm ntau yam ntaub ntawv thiab cov affinity ntawm lubricating roj kom cov bearings nws tus kheej muaj peev xwm ua hauj lwm rau lub sij hawm ntev tsis muaj lubrication sab nraud, tab sis cov yam ntxwv no kuj ua rau lub lubrication ntawm cov roj impregnated bearings txawv ntawm cov lubrication zoo tib yam. Feem ntau, nws yuav nyob rau hauv ib qho tsis tiav roj zaj duab xis lub xeev, thiab kev sib txhuam uas tshwm sim yog kev sib txhuam sib xyaw.
Daim ntawv thov ntawm Roj-impregnated Bearings
Roj-impregnated bearings yog tus nqi zoo thiab siv tau yooj yim. Thaum lawv tshwm sim, lawv tau txais kev pom zoo hauv kev tsim khoom, suav nrog kev tsim tsheb, khoom siv hauv chaw ua haujlwm, khoom siv hauv tsev, thiab kev siv tshuab. Roj-impregnated bearings yog siv nyob rau hauv ntau yam teb.
