Tam sim no, cov txheej txheem sab hauv ntawm qhov sib sib zog nqus groove kaw pob bearings hauv kuv lub teb chaws yuav luag zoo ib yam li cov tuam txhab txawv teb chaws siab heev.Txawm li cas los xij, kev vibration thiab suab nrov ntawm cov khoom zoo li no hauv kuv lub teb chaws nyob deb ntawm cov khoom txawv teb chaws.Qhov laj thawj tseem ceeb yog kev cuam tshuam ntawm kev tsim khoom thiab kev ua haujlwm.Los ntawm qhov kev xav ntawm kev lag luam bearing, cov yam ntxwv ntawm kev ua haujlwm tuaj yeem daws tau los ntawm kev muab cov kev xav tau tsim nyog rau lub cav tseem ceeb, thiab yuav ua li cas txo qhov kev vibration thiab suab nrov los ntawm kev tsim khoom yog ib qho teeb meem uas kev lag luam bearing yuav tsum daws.
Ntau qhov kev ntsuam xyuas hauv tsev thiab txawv teb chaws tau pom tias kev ua haujlwm zoo ntawm tawb, rings, thiab cov pob steel muaj qhov sib txawv ntawm cov kev cuam tshuam ntawm cov kabmob vibration.Ntawm lawv, kev ua haujlwm zoo ntawm cov npas steel muaj qhov pom tseeb tshaj plaws ntawm cov kabmob vibration, ua raws li kev ua haujlwm zoo ntawm cov nplhaib.Qhov tseem ceeb tshaj plaws yog roundness, waviness, nto roughness, nto pob, thiab lwm yam ntawm steel pob thiab rings.
Qhov teeb meem tseem ceeb tshaj plaws ntawm kuv lub teb chaws cov khoom lag luam steel pob yog tias cov nqi vibration yog qhov loj thiab qhov tsis xws luag yog qhov loj (ib qho taw tes, pab pawg taw tes, qhov tob, thiab lwm yam).Txawm hais tias qhov roughness ntawm qhov chaw, qhov loj me, cov duab, thiab qhov yuam kev tsis qis dua li theem sab nraud ntawm lub voj voog, qhov kev vibration tus nqi ntawm cov kabmob tom qab sib dhos yog siab, thiab txawm tias muaj suab nrov txawv txav.Mechanical quality teeb meem.Rau lub nplhaib, channel waviness thiab nto roughness yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev co ntawm cov kabmob.Piv txwv li, thaum lub roundness ntawm lub puab thiab sab grooves ntawm me me thiab nruab nrab-qhov loj qhov sib sib zog nqus groove pob bearings yog ntau tshaj 2 μm, nws yuav muaj kev cuam tshuam loj rau kev co ntawm cov kabmob.Thaum lub waviness ntawm sab hauv thiab sab nraud grooves ntau dua 0.7 μm, qhov kev vibration tus nqi ntawm cov kabmob yuav nce ntxiv nrog qhov nce ntawm qhov waviness.Kev puas tsuaj loj rau cov grooves tuaj yeem ua rau muaj kev vibration ntau dua 4 dB, thiab txawm tsim cov suab txawv txav.Txawm hais tias nws yog lub pob steel lossis lub ferrule, lub waviness yog tsim nyob rau hauv cov txheej txheem sib tsoo.Txawm hais tias super-tiav tuaj yeem txhim kho qhov waviness thiab txo qhov roughness, qhov kev ntsuas tseem ceeb tshaj plaws yog txo qhov waviness thaum lub sij hawm super-tiav thiab tsis txhob random pob.Muaj ob qhov kev ntsuas tseem ceeb: Sib sib zog nqus groove pob bearings txo kev co
Ib qho yog los txo qhov kev vibration ntawm dov nto sib tsoo thiab super-tiav kom tau zoo nto machining duab raug thiab nto zoo nkauj zoo nkauj.Txhawm rau txo kev co, lub tshuab super-sib tsoo yuav tsum muaj kev co zoo.Nyob rau hauv high-speed sib tsoo, lub sib tsoo quab yuam yog me me, lub sib tsoo deterioration txheej yog nyias, nws tsis yooj yim rau hlawv, thiab nws muaj peev xwm txhim kho lub machining raug thiab efficiency, uas muaj ib tug zoo ntxim rau cov uas tsis muaj suab nrov pob bearings;qhov dynamic thiab zoo li qub nruj ntawm cov ntxaiv thiab nws cov yam ntxwv ceev muaj kev cuam tshuam zoo rau kev sib tsoo ntawm cov suab nrov qis pob bearings.Qhov siab dua qhov nruj, qhov tsawg dua qhov kev sib tsoo ceev yog qhov hloov ntawm kev sib tsoo quab yuam, thiab qhov me dua qhov kev vibration ntawm kev sib tsoo;Lub rigidity ntawm spindle bearing yog txhim kho, thiab random dynamic tshuav nyiaj li cas technology yog siv los txhim kho kev co kuj ntawm kev sib tsoo spindle.Lub vibration ceev ntawm txawv teb chaws sib tsoo taub hau (xws li Gamfior) yog hais txog ib feem kaum ntawm domestic general spindles;Nws yog ib qho tseem ceeb heev los txhim kho qhov kev ua tau zoo thiab hnav khaub ncaws zoo ntawm kev sib tsoo log oilstone.Tam sim no, qhov teeb meem tseem ceeb ntawm kev sib tsoo log oilstone hauv kuv lub teb chaws yog qhov tsis zoo ntawm cov qauv, uas cuam tshuam rau qhov zoo ntawm cov suab nrov qis pob bearing sib tsoo thiab sib tsoo;txaus txias los txhim kho qhov pom tseeb;nce qhov kev daws teeb meem ntawm kev pub noj kom zoo thiab txo qhov kev noj zaub mov tsis zoo;Kev sib tsoo tsim nyog thiab kev ua haujlwm tsis zoo thiab cov txheej txheem ua tiav yog yam uas tsis tuaj yeem tsis quav ntsej.Cov nyiaj sib tsoo yuav tsum yog me me, thiab cov duab thiab txoj hauj lwm kam rau ua yuav tsum nruj.
Sib sib zog nqus groove pob bearings txhim kho precision
Qhov thib ob yog los txhim kho qhov tseeb ntawm machining datum nto thiab txo qhov yuam kev hauv kev sib tsoo.Sab nraud txoj kab uas hla thiab lub ntsej muag kawg yog qhov muab tso rau hauv cov txheej txheem sib tsoo.Kev ua yuam kev ntawm sab nraud txoj kab uas hla mus rau qhov zawj superprecision yog indirectly kis los ntawm qhov yuam kev ntawm lub sab nraud txoj kab uas hla mus rau lub zawj sib tsoo, thiab zawj sib tsoo mus rau qhov zawj superprecision.Yog hais tias lub workpiece yog bumped thiab puas thaum lub sij hawm hloov cov txheej txheem, nws yuav ncaj qha cuam tshuam rau ntawm raceway processing nto, uas yuav cuam tshuam rau kev co ntawm bearing.Yog li ntawd, cov kev ntsuas hauv qab no yuav tsum tau ua: txhim kho cov duab raug ntawm qhov chaw siv qhov chaw;kev sib kis yog du thaum ua, tsis muaj pob;Cov duab thiab txoj haujlwm yuam kev ntawm qhov nyiaj pub dawb yuav tsum tsis txhob loj dhau, tshwj xeeb tshaj yog thaum qhov nyiaj pub me me, qhov yuam kev ntau dhau yuav ua rau cov duab raug qhov kawg ntawm qhov kawg ntawm kev sib tsoo thiab superfinishing kom tsis txhob raug kho kom zoo rau qhov yuav tsum tau ua, uas tiag tiag. cuam tshuam qhov sib xws ntawm kev ua kom zoo.
Los ntawm kev txheeb xyuas saum toj no, nws tsis yog qhov nyuaj kom pom tias cov kab tsis siv neeg tsis siv neeg muaj qhov ua haujlwm siab thiab ruaj khov tshuab cuab yeej yog qhov tsim nyog tshaj plaws rau kev sib tsoo cov suab nrov qis pob bearings, uas tuaj yeem zam kev ua pob, txo qis kev sib kis. , tshem tawm cov khoom siv dag zog, txhim kho kev ua haujlwm zoo thiab zoo sib xws, txo cov nqi tsim khoom, thiab txhim kho cov txiaj ntsig kev lag luam.
