Yethula ukunemba kwama-bearings anemba ngemva kokufakwa
1. Indlela yokuthuthukisa ukunemba
Ngemuva kokuthi ukuthwala kufakwe injini eyinhloko, uma ukukhishwa kwe-radial ye-shaft eyinhloko kulinganiswa, kungatholakala ukuthi inani elilinganisiwe le-revolution ngayinye linoshintsho oluthile;lapho ukulinganisa okuqhubekayo kwenziwa, kungatholakala ukuthi ngemva kwenani elithile lokuguquguquka, lolu shintsho luzocishe luphinde.Vele.Inkomba yokulinganisa izinga lalolu shintsho ukunemba kokuzungezisayo.Inani lama-revolution adingekayo ukuze uguquko lubonakale cishe izimpinda kumele "quasi-period" yokunemba kokuzungezisa komjikelezo.Ubukhulu boshintsho esikhathini esiyi-quasi bukhulu, okuwukunemba kokujikeleza komjikelezo..Uma ukulayisha kuqala okufanelekile kusetshenziswa ku-shaft eyinhloko, isivinini sikhuphuka kancane kancane ukuze sivale isivinini sokusebenza, ukuze kusetshenziswe umphumela othi "run-in" wokuthwala, ongathuthukisa ukunemba kokujikeleza kwe-cyclic shaft eyinhloko.
2. Indlela yokuthuthukisa ukunemba kokunemba
Ukuhlolwa kwefekthri kukhiqiza amathuluzi anembayo, i-shaft eyinhloko isebenzisa amabheringi ohlobo lwe-6202/P2 futhi ukunemba kwayo namanje akukakwazi ukuhlangabezana nezidingo, bese ujiya ijenali bese wenza umgwaqo womjaho kuyo ukuze umiselele indandatho yangaphakathi, futhi ulinganise ukuminyana okuncibilikayo kwensimbi. ibhola, ngokobukhulu Iqembu ngalinye lamabhola ensimbi amathathu lihlukaniswa ngesikhawu esicishe sibe ngu-120°.Ngenxa yokwehliswa kwendawo enzima yokukhanda kanye nendawo ehambisanayo esindayo, ukuqina kwesistimu yokuthwala i-shaft kuyathuthukiswa, futhi amabhola amathathu amakhulu namabhola amathathu amancane kakhulu Ukusatshalaliswa okucishe kulingane kwamabhola ensimbi kuthuthukisa ukunemba kokuzungezisa. i-shaft, ngaleyo ndlela ihlangabezana nezidingo zokunemba zethuluzi.
3. Indlela yokuqinisekisa ephelele yokunemba kokufaka
Ngemuva kokuthi i-angular contact ball bearing ifakwe ku-spindle, ukulandelana kokuhlola ukunemba kokufakwa kungokulandelayo (ukuthatha i-lathe evamile enobubanzi be-shaft obungu-60-100mm njengesibonelo):
(1) Kala usayizi we-shaft kanye nembobo yesihlalo sokuthwala ukuze uthole ukunemba okuhambisanayo kwe-bheringi.Izidingo zokufanisa zimi kanje: iringi engaphakathi kanye ne-shaft kusebenzisa ukulingana kokuphazamiseka, kanti inani lokuphazanyiswa ngu-0~+4μm (0 ngomthwalo omncane nokunemba okuphezulu); futhi inani lemvume liyi-0 ~ + 6μm (kodwa lapho isiphetho samahhala sisebenzisa i-angular contact ball bear, imvume ingabuye inyuswe);iphutha lokujikeleza kwendawo phakathi kwe-shaft kanye nembobo yesihlalo ingaphansi kuka-2μm, ukuthwala Ukufana kobuso bokuphela kwesikhala esisetshenzisiwe kungaphansi kuka-2μm, ukuphuma kokuphela kwangaphakathi kwehlombe le-shaft elibheke ebusweni bokuphela kwangaphandle kungaphansi kwe-2μm ;ukuphuma kwembobo yesihlalo sokuthwala ihlombe ku-axis kungaphansi kwe-4μm;ukuphuma kwesiphetho sangaphakathi sekhava yangaphambili yokuphotha ebheke eksisi kungaphansi kuka-4μm.
(2) Ukuze kufakwe i-bearing yangaphambili ekugcineni okugxilile ku-shaft, hlanza kahle i-bearing ngophalafini wokuhlanza ohlanzekile.Ukuze ugcobe amafutha, qala ngokujova i-solvent ephilayo equkethe u-3% kuya ku-5% amafutha ku-bearing of degreasing nokuhlanza, bese usebenzisa I-oil gun igcwalisa inani elithile lamafutha ku-bearing (ibalwa ku-10% kuya ku-15% we-bearing. umthamo wendawo);ukushisa i-bearing ukukhulisa izinga lokushisa libe ngu-20 kuya ku-30 ​​° C, bese ufaka ukuthwala ekugcineni kwe-shaft ngomshini we-hydraulic;cindezela umkhono we-adaptha ku-shaft Bese ucindezela ubuso bokugcina be-bearing ngokucindezela okufanele ukuze ukwenze ku-axially positioned;gingqa ibhande lesikali sentwasahlobo eringini yangaphandle ye-bearing, bese usebenzisa indlela yokulinganisa i-torque yokuqala ukuze uhlole ukuthi ukulayisha kwangaphambili okucacisiwe kunoshintsho olukhulu (ngisho noma ukuthwala kulungile)., kodwa ukulayisha kuqala kungase futhi kushintshe ngenxa yokuguqulwa kokulingana noma ikheji).
(3) Faka i-bearing-shaft embobeni yesihlalo, shisisa imbobo yesihlalo ukuze ukhuphule izinga lokushisa ngo-20-30°C, futhi usebenzise ukucindezela okuqhubekayo okumnene ukuze ufake i-bearing-shaft assembly emgodini wesihlalo;lungisa ikhava yangaphambili ukuze wenze ikhava yangaphambili iqine Isamba esiqinile ngu-0.02⽞0.05μm, ngokusekelwe ekugcineni kobuso besihlalo esiphethe, ikhanda lenkomba yokudayela iphambene nobuso bejenali, futhi i-shaft izungeziswe ukuze linganisa ukuphuma, futhi iphutha liyadingeka libe ngaphansi kuka-10μm;inkomba yokudayela ibekwe ku-shaft., ikhanda legeji limelene nendawo engaphakathi yembobo yesihlalo sangemuva, futhi i-shaft iyazungeziswa ukuze kulinganiswe ukuhlangana kwezimbobo zezihlalo zangaphambili nangemuva zesihlalo sokuthwala.
