Tsim kev vibration hauv bearings Feem ntau hais lus, dov bearings lawv tus kheej tsis tsim suab nrov. Cov "cov kabmob suab nrov" uas feem ntau xav tau yog qhov ua tau zoo ntawm cov kabmob ncaj qha lossis cuam tshuam nrog cov qauv nyob ib puag ncig. Qhov no yog vim li cas ntau zaus qhov teeb meem suab nrov tuaj yeem suav tias yog qhov teeb meem kev vibration uas cuam tshuam rau tag nrho cov kabmob daim ntawv thov.
(1) Kev vibration zoo siab los ntawm kev hloov pauv ntawm cov khoom thauj khoom dov: Thaum lub radial load yog siv rau qee yam kabmob, tus naj npawb ntawm cov khoom dov nqa lub load yuav hloov me ntsis thaum lub sijhawm ua haujlwm, uas ua rau qhov sib txawv ntawm kev thauj khoom. Qhov tshwm sim ntawm kev vibration tsis tuaj yeem zam tau, tab sis nws tuaj yeem raug txo los ntawm axial preloading, uas yog loaded ntawm tag nrho cov dov ntsiab (tsis muaj feem xyuam rau cylindrical roller bearings).
(2) Kev puas tsuaj ib nrab: vim kev ua haujlwm lossis kev teeb tsa tsis raug, ib feem me me ntawm cov kabmob sib tw thiab cov khoom dov tuaj yeem raug puas tsuaj. Hauv kev ua haujlwm, dov tshaj cov kabmob uas puas lawm yuav tsim cov kev vibration tshwj xeeb. Kev vibration zaus tsom xam tuaj yeem txheeb xyuas cov kabmob puas. Lub hauv paus ntsiab lus no tau raug siv rau cov cuab yeej saib xyuas mob kom paub txog kev puas tsuaj ntawm cov kabmob. Txhawm rau xam cov kabmob zaus, thov xa mus rau qhov kev pabcuam suav "Bearing Frequency".
(3) Qhov tseeb ntawm cov khoom muaj feem xyuam: Nyob rau hauv cov ntaub ntawv ntawm ib tug zoo haum ntawm lub nplhaib bearing thiab bearing lub rooj los yog tsav ncej, lub nplhaib bearing yuav deformed los ntawm kev sib piv cov duab ntawm cov nyob ib sab. Yog tias nws deformed, nws yuav vibrate thaum ua haujlwm.
(4) Cov pa phem: Yog tias khiav hauv qhov chaw muaj kuab paug, impurities tuaj yeem nkag mus rau hauv cov kabmob thiab raug tsoo los ntawm cov khoom dov. Lub degree ntawm kev co tsim nyob ntawm tus naj npawb, qhov loj thiab muaj pes tsawg leeg ntawm crushed impurity hais. Txawm hais tias nws tsis tsim ib daim ntawv zaus, lub suab nrov nrov tuaj yeem hnov.
Qhov ua rau lub suab nrov ua los ntawm cov kabmob dov yog qhov nyuaj dua. Ib qho yog hnav ntawm mating nto ntawm sab hauv thiab sab nrauv ntawm cov kabmob. Vim qhov kev hnav zoo li no, kev sib raug zoo ntawm cov kabmob thiab cov vaj tsev, thiab cov kabmob thiab cov ncej raug puas tsuaj, ua rau lub axis deviate los ntawm txoj haujlwm raug, thiab lub suab nrov txawv txav tshwm sim thaum lub ncej txav ntawm kev kub ceev. Thaum cov kabmob qaug zog, cov hlau ntawm nws qhov chaw yuav tev tawm, uas yuav ua rau kom cov radial clearance ntawm cov kabmob thiab tsim suab nrov txawv txav. Tsis tas li ntawd, tsis txaus cov kabmob lubrication, tsim kev sib txhuam qhuav, thiab cov kabmob tawg yuav ua rau lub suab nrov txawv txav. Tom qab cov kabmob hnav thiab xoob, lub tawb yuav xoob thiab puas, thiab lub suab nrov txawv txav yuav raug tsim.
Cov kabmob yuav tsum tau ua tib zoo siv hauv lub neej txhua hnub. Cia peb saib cuaj yam uas peb yuav tsum tau saib xyuas.
1. Cov riveting qhov chaw nyob rau hauv lub harvester zoo li lub movable riam los ua ke. Cov rivets feem ntau yog ua los ntawm txias extrusion thiab yuav tsum tsis txhob rhuab thaum lub sij hawm riveting. Cov cua sov yuav txo qhov muaj zog ntawm cov khoom siv. Tom qab riveting, ib txoj kev xuas nrig ntaus yog siv los ntxiv dag zog rau cov hniav thiab riam ncej.
2. Cov khoom tsis zoo, tshwj xeeb tshaj yog pin shafts, nias daim, lub tes tsho, thiab horns tsis tuaj yeem hloov thiab kho nrog cov roj butter ntxiv thaum lub sij hawm tu, xws li kev siv lub sij hawm ntev ntawm cov khoom uas hnav mus rau qhov txwv yuav ua rau lub neej ntawm lwm cov tshuab ua haujlwm. luv.
3. Kho cov shafts tsis muaj lub tshuab ntsuas. Thaum kho ntau yam shafts uas yuav tsum tau muaj kev sib npaug, lub thrust bearing tuaj yeem ntsia tau rau ntawm ib kawg ntawm tus ncej, clamped ntawm peb lub puab tsaig ntawm lub tshuab dhos, thiab lwm qhov kawg tuaj yeem txhawb nqa los ntawm qhov chaw. Yog tias lub tshuab dhos luv luv, qhov chaw tuaj yeem siv tau. Lub thav duab clamps SKF bearing mounted ntawm tus ncej ntawm lwm qhov kawg kom txog thaum qhov sib npaug raug kho. Tab sis thaum ntsuas qhov hnyav, siv cov ntsia hlau kom nruj, thiab sim tsis txhob siv hluav taws xob vuam kom sib npaug ntawm qhov hnyav.
4. Nyob rau hauv cov txheej txheem txij nkawm, vim muaj ntau yam ntawm cov khoom siv bearing, nws tsis yooj yim rau kev yuav khoom, thiab tuaj yeem ua tiav nrog cov khoom pov tseg. Tam sim no, feem ntau ntawm cov ncej hauv peb lub teb chaws yog tsim los ntawm 45 # carbon steel. Yog tias xav tau quenching thiab tempering, nws tuaj yeem siv rau hauv qhov xwm txheej phem. Cov pa oxygen thiab lub ntiaj teb rauv cua sov qhov yuav tsum tau ua kom liab thiab dub thiab muab tso rau hauv dej ntsev, nyob ntawm qhov xav tau.
5. Thaum ua tiav lub tes tsho, rub cov roj zawj hauv lub tes tsho qhov ntau li ntau tau. Vim tias nws nyuaj heev rau refuel qee qhov ntawm lub tshuab txiav, butter thiab cov roj cav hnyav tuaj yeem siv tau qhov twg nws nyuaj rau refuel, tsuas yog lub tes tsho nylon. Qhov twg siv lub tes tsho nylon, nws yog qhov zoo tshaj plaws tsis txhob hloov lawv nrog cam khwb cia hlau, tooj liab lossis txhuas, vim tias lub tes tsho nylon yuav tiv taus qee yam cuam tshuam thiab yuav tsis deform.
6. Kev kho qhov tseem ceeb thiab qhov tseem ceeb ntawm txoj hlua rub thiab lub ncej yuav tsum xyuas kom meej tias qhov loj me tsis hloov ua ntej. Tsis txhob nce qhov loj ntawm tus yuam sij, txwv tsis pub nws yuav cuam tshuam rau lub zog ntawm tus ncej. Txoj kev tseem ceeb ntawm tus ncej tuaj yeem kho nrog hluav taws xob vuam muab tub lim thiab milled nyob rau hauv qhov kev taw qhia ntawm tus yuam sij qub. Ib txoj hauv kev tseem ceeb, txoj hauv kev tseem ceeb ntawm lub pulley tuaj yeem teeb tsa nrog lub tes tsho (hloov haum) txoj kev. Tom qab qhov kev teeb tsa tiav lawm, siv lub taub hau ntsaws ntsaws rau hauv lub tes tsho kom nruj tus yuam sij.
7. Kho qhov hydraulic ntawm lub tshuab txiav. Tshem lub distributor thiab lub valve txo, thiab siv lub twj tso kua mis cua kom siab cov kav dej. Cov roj hydraulic yuav tsum tau lim thiab tso tawm thaum cov roj hydraulic rov qab. Kev kho ntawm hydraulic sib dhos yog feem ntau yog lub foob. Nws yog qhov zoo tshaj los hloov lub foob tom qab tshem nws.
