Ukunemba kwama-bearings anemba ngemva kokufakwa

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 kwenziwa ngokuqhubekayo, kungatholakala ukuthi ngemva kwenani elithile lokuguquguquka, ushintsho luzoba cishe ngokuphindaphindiwe Ukuvela.Inkomba yokulinganisa izinga lalolu shintsho ukunemba kokuzungezisayo.Inani lama-revolution adingekayo ekuphindaphindweni okulinganiselwe koshintsho limelela "inkathi ye-quasi" yokunemba kokujikeleza komjikelezo.Ubukhulu boshintsho esikhathini esiyi-quasi bukhulu, okusho ukuthi, ukunemba kokuzungezisayo akulungile..
Uma ukulayisha kuqala okufanele kusetshenziswe ku-shaft eyinhloko, isivinini sikhuphuka kancane kancane ukuze sivale isivinini sokusebenza ukuze kusetshenziswe umphumela "wokugijima" we-bearing, ongathuthukisa ukunemba kokujikeleza kwe-cyclic shaft eyinhloko.
2. Indlela yokuthuthukisa ukunemba kokunemba
Isilingo sefekthri sikhiqize ithuluzi elinembayo.I-shaft eyinhloko isebenzise ama-bearings angu-6202/P2, kodwa ukunemba kwayo namanje akukwazanga ukuhlangabezana nezidingo.Kamuva, leli phephabhuku laqiniswa futhi kwenziwa umzila womjaho ukuze kushintshwe iringi yangaphakathi.Iqembu ngalinye lamabhola amathathu lihlukaniswa isikhawu esicishe sibe ngu-120°.Ngenxa yokwehliswa kwendawo yokucubungula esindayo kanye nendawo esindayo ehambisanayo, iphinde ithuthukise ukuqina kwesistimu ye-shaft-bearing, kuyilapho izinhlamvu ezintathu ezinkulu nezincane ezintathu Ukusabalalisa okucishe kulingane kwamabhola ensimbi kuthuthukisa ukunemba kokujikeleza kwe-shaft. , ngaleyo ndlela ihlangabezana nezimfuneko zokunemba zethuluzi.
3. Indlela yokuqinisekisa ephelele yokunemba kokufaka
Ngemva kokufaka ibhola lokuxhumana le-angular elithwele ku-shaft eyinhloko, ukulandelana kokuqinisekisa ukunemba kokufakwa kungokulandelayo (kuthatha 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 yangaphakathi kanye ne-shaft kusebenzisa ukulingana kokuphazamiseka, futhi ukulingana kokuphazamisa kungu-0~+4μm (0 ekulayisheni okulula nokunemba okuphezulu); imvume ingu-0 ~ + 6μm (kodwa imvume inganyuswa lapho ukuthwala ekugcineni kwamahhala kusebenzisa i-angular contact ball bear);iphutha lokuyindilinga le-shaft kanye nendawo yembobo yezindlu ingaphansi kwe-2μm, futhi ukuthwala Ukufana kobuso bokuphela kwe-spacer esetshenzisiwe kungaphansi kuka-2 μm, ukuphuma kokuphela kwangaphakathi kwehlombe le-shaft kuya ebusweni bokuphela kwangaphandle. ngaphansi kuka-2 μm;ukuphuma kwehlombe lomgodi wezindlu ezithwalayo ku-axis kungaphansi kuka-4 μm;ukuphuma kwesiphetho sangaphakathi sekhava yangaphambili ye-shaft eyinhloko ku-eksisi kungaphansi kuka-4 μm.
(2) Ukufakwa kwe-front bear ye-fixed end ku-shaft
Hlanza i-bearing kahle 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 isibhamu samafutha ukugcwalisa inani elithile lamafutha ku-bearing (ibalwa ku-10% kuya ku-15% we-grease). ukuthwala umthamo wesikhala);ukushisa i-bearing ukukhulisa izinga lokushisa ngo-20 kuya ku-30 ​​° C, bese ufaka ukuthwala ekugcineni kwe-shaft ngomshini we-hydraulic;cindezela umkhono we-adaptha ku-shaft bese ucindezela ngokumelene nobuso bokuphela kokuthwala ngengcindezi efanelekile ukuyenza i-axially Positioning;vula ibhande lebhalansi yasentwasahlobo eringini yangaphandle ye-bearing, futhi usebenzise indlela yokulinganisa i-torque yokuqala ukuze uqinisekise ukuthi ukulayisha kwangaphambili okucacisiwe kunoshintsho olukhulu (ngisho noma ukuthwala kulungile, kodwa ngenxa yokuguquguquka kokulingana. noma ikheji, ukulayisha kuqala nakho kuzoshintsha.
(3) Faka umhlangano we-bearing-shaft emgodini wesihlalo
Shisisa imbobo yesihlalo ukwandisa izinga lokushisa ngo-20-30 ° C, futhi ufake umhlangano we-bearing-shaft emgodini wesihlalo ngokucindezela okuqhubekayo nokumnene;lungisa ikhava yangaphambili ukuze inani lokubopha lekhava yangaphambili libe ngu-0.02-0.05 μm, uthatha indawo yokugcina yangaphandle yesihlalo esithwalayo njenge-Benchmark, ubeke inhloko yegeji yokudayela ebusweni bephephabhuku, uzungezisa i-shaft ukuze ulinganise. ukuphuma kwayo, futhi iphutha liyadingeka ukuba libe ngaphansi kuka-10 μm;beka igeji yokudayela ku-shaft, yenza ikhanda le-dial lithinte indawo engaphakathi yembobo yesihlalo esingemuva, bese uzungezisa i-shaft Ukuze ulinganise ukuhlangana kwezimbobo zezindlu zangaphambili nangemuva zesihlalo sokuthwala.
(4) Ngokukhetha beka isiphetho samahhala endaweni engase isuse ukuchezuka, futhi uyifake endaweni yokusekela yangemuva yezindlu ezithwalayo ukuze uqedele ukuchezuka kwe-mutual roundness kanye nokuchezuka kwe-coaxiality ngangokunokwenzeka.
Ukufakwa kwama-double-row short cylindrical roller bearings ane-tapered bore Lapho ufaka i-NN3000K uchungechunge lwama-roller ama-double cylindrical roller bearings ane-tapered bore, kufanele kuqashelwe ukufanisa okulungile kobubanzi bangaphakathi be-bearing kanye ne-taper ye-shaft, futhi indlela yokubala ingasetshenziswa esimweni somthamo omncane wokukhiqiza.Ukulinganiswa kokuxhumana, kodwa uma iqoqo lokukhiqiza lilikhulu, kungcono ukusebenzisa i-taper gauge enembile ukuze ulinganise.
Uma ufaka i-bearing ku-shaft tapered, indandatho yangaphakathi kufanele ilungiswe endaweni efanele endaweni ye-axial ukuze imvume ye-radial isondele ku-zero.
