Ngemikhiqizo yezimoto zikagesi, uhlelo lokuthwala kanye nohlelo lwendandatho yokuqoqa ama-motor e-wound rotor kudinga ukulungiswa njalo kanye nokulungiswa ngenxa yokuguga nokusetshenziswa kwezinto. Izibonelo ezimbili ezivamile kakhulu zinikezwa njengezibonelo: Abanye abakhiqizi abathathi izinyathelo zokulwa nokuxegisa izikhonkwane zezimoto, okuholela ekukhululekeni nasekuweni kwama-bolt okubopha; abanye abakhiqizi bezimoto abaklami idivayisi yokufaka uwoyela yama-bearings ngaphandle kokumisa umshini ukuze bonge izindleko, okuholela ekutheni imoto ibambe futhi ishe ngenxa yokuntuleka kwamafutha kuma-bearings.
Izici ezithinta ikhwalithi yesistimu yokuthwala izimoto
Kusukela ezimweni zokwehluleka kwama-rolling bearings kuma-motor agcotshwe ngamafutha, kungabonakala ukuthi iningi lokwehluleka kubangelwa ukunganeli kwe-lubricate oil viscosity. Uma i-viscosity yamafutha okugcoba iphansi, kulapho amandla okuthwala umthwalo we-bearings aba mabi khona, futhi ifilimu yamafutha okugcoba ithambekele kakhulu ekuqhekekeni. Izinto zensimbi ezisezindaweni ezihambayo ngaphakathi kwe-rolling bearings zizothintana ngqo, okuholela ekukhushulweni okwandisiwe kanye nokuguguleka okusheshayo, futhi impilo yesevisi ye-rolling bearings izofinyezwa kakhulu noma ingase ihlupheke ngenxa yokusha noma izingozi zokuphuka. Kodwa-ke, uma i-viscosity yamafutha okugcoba iphezulu kakhulu, izokwandisa ukumelana nokukhushulwa, ikhiqize ukushisa okwengeziwe ngenxa yokuxubana kwe-lubricant, futhi ikhulise ukusetshenziswa kwamandla kwesistimu. Ngakolunye uhlangothi, kuma-rolling bearings asebenza ngaphansi kwezimo ezikhethekile njengesivinini esikhulu, umthwalo ophezulu, kanye nokushisa okuphezulu, kungaba nezidingo ezikhethekile zokuvimbela ukugqwala, ukumelana ne-oxidation, ukulwa nokuguguleka, kanye nokuthuthukisa amandla okumunca kawoyela okugcoba. Ngakho-ke,Ukukhethwa kwamafutha okugcoba kuhilela kakhulu ukunquma izinga le-viscosity lamafutha okugcoba kanye nezinhlobo zezithasiselo ezisetshenziswayo noma ukukhetha imikhiqizo ehlukene yamafutha okugcoba enezithasiselo ezithile. Izici ezilandelayo zinomthelela omkhulu ekugcotshweni kwama-motor bearings.
1. Isivinini semoto
Uma isivinini semoto siphezulu, kulapho kungcono khona ukukhethauwoyela wokugcoba one-viscosity ephansiukuvimbela ukwanda kokumelana nokungqubuzana kanye nokukhiqizwa kokushisa ngokweqile; ngokuphambene nalokho, ezimweni zesivinini esiphansi, uwoyela wokugcoba one-viscosity ephezulu kufanele usetshenziswe ukuthuthukisa amandla okuthwala umthwalo.
2.Izinga lokushisa lokusebenza
Izinga lokushisa lokusebenza lithinta ushintsho lwe-viscosity yamafutha okugcoba kanye nomphumela wokugcoba. Ngakho-ke, lapho izinga lokushisa lokusebenza liphansi,uwoyela wokugcoba one-viscosity ephansikufanele kukhethwe; uma izinga lokushisa lokusebenza liphezulu kakhulu,uwoyela wokugcoba one-viscosity ephezulunoma eyodwa enezithasiselo ezifanele kufanele ikhethwe. Kuye ngokushisa okuhlukile kwemvelo, i-viscosity yamafutha okugcoba akhethiwe kufanele nayo ishintshe ngokufanele. Isibonelo, lapho kugcoba i-bearing efanayo ebusika, amafutha okugcoba ane-viscosity ephansi kufanele akhethwe uma kuqhathaniswa naleyo eningizimu noma ehlobo. Lapho izinga lokushisa lokusebenza lishintsha njalo, amafutha okugcoba anezici ezinhle kakhulu ze-viscosity-temperature kufanele akhethwe, okungukuthi, i-viscosity yamafutha okugcoba akufanele ishintshe kakhulu ngokwanda noma ukwehla kwezinga lokushisa lokusebenza ukuqinisekisa ukuthi ubukhulu befilimu yamafutha buhlala buzinzile ngaphakathi kobubanzi obuthile.
3. Impahla ye-Kinetic
Ngesikhathi sokunyakaza, kuba khona imithelela, ukudlidliza, izinguquko ezivamile emthwalweni, ukushintshashintsha kwesivinini, ukuqala, ukuma, ukuhlehla, futhi lapho kwenziwa ukunyakaza okubuyelanayo noma okungahleliwe, akuhambisani nokwakheka kwamafilimu kawoyela. Ngakho-ke,uwoyela wokugcoba one-viscosity ephezulukufanele kukhethwe. Ngezinye izikhathi, amafutha noma ngisho nezinto zokugcoba eziqinile zingasetshenziswa ukuqinisekisa ukugcoba okuthembekile.
4.Umthwalo osebenzayo
Uma umthwalo ukhulu kakhulu ngenxa yokuthwala okugoqekayo,i-viscosity iyandauwoyela wokugcoba kufanele ukhethwe. Uwoyela wokugcoba kufanele futhi ube nokugeleza okuhle kanye nezakhiwo zokucindezela okukhulu ukuvimbela uwoyela wokugcoba ukuthi ungacindezelwa ngaphandle kwepheya lokungqubuzana noma ubangele ukuthintana okuqondile phakathi kwezinsimbi.
5. Ukuthwalaukunemba
Uma izindawo zokungqubuzana zokunyakaza kwamabhere ziqinile, ngokuvamile kuyalulekwa ukusebenzisa uwoyela one-viscosity ephezulu ukuze umelane nengcindezi enkulu yendawo eyakheka ngenxa yokuxhumana okungekuhle. Ngenkathi lapho ukunemba kwezindawo zokungqubuzana ngesikhathi sokunyakaza kuphezulu,uwoyela wokugcoba one-viscosity ephansikufanele kukhethwe ukuze kuncishiswe ukulahleka kwamandla okungadingekile kanye nokwenyuka kwezinga lokushisa.
6. Izimo zemvelo
Uma amabheringi esebenza ngaphansi kwezimo zomswakama, ukuba khona kwamagesi agqwalisayo, izinga lokushisa eliphansi, uthuli, kanye nemisebe enamandla, uwoyela wokugcoba uthambekele ekungcoleni nasekuwohlokeni. Ngalesi sikhathi, uwoyela wokugcoba omelana kakhulu namanzi, ukumelana nokuguguleka, ukumelana nokugqwala, ukumelana nokubanda kanye nokumelana nemisebe kufanele kukhethwe. Ezindaweni lapho kunamanzi agelezayo, ukufutha koketshezi oluhlanganisiwe, umoya omanzi noma uthuli olunzima kanye nemfucumfucu, uwoyela wokugcoba ngokuvamile awufaneleki futhi kufanele kusetshenziswe amafutha esikhundleni salokho.
7.Izici zesakhiwo
Uma i-radial clearance ye-rolling bearing incane, ukunemba komshini wokusebenza kwezindawo zokungqubuzana kuzoba phezulu, futhi i-viscosity yamafutha okugcoba kufanele ibe phansi.
8. Ukuthwalaubulukhuni
Uma ubulukhuni bobuso bokungqubuzana kokunyakaza kokuthwala buphansi,uwoyela wokugcoba oqinile kakhulukufanele kukhethwe futhi inani lamafutha kufanele lanele; ngakolunye uhlangothi, i-viscosity yamafutha okugcoba ingancishiswa. Ukuze kusetshenziswe ngokugcwele umphumela wamafutha okugcoba,kuyadingeka ukukhetha indlela efanele yokugcoba kanye nokugcoba kwekhwalithi ephezulu ukuze kuhambisane nezimo zokusetshenziswa.Ngesikhathi sokuhlanganiswa kwemoto, igrisi yokugcoba efakwe ekamelweni lokuthwala kumele ihlanzeke. Uma igrisi yokugcoba ingahlanzekile, iqukethe ukungcola, ikakhulukazi ukungcola okuqinile, kulula ukubangela ukuguguleka okungavamile kwebheringi futhi kuholele ekwehlulekeni kwebheringi. Inani lokugcwalisa legrisi yokugcoba kufanele lifaneleke. Uma inani lokwengeza lincane kakhulu, ibheringi izoshiswa ngenxa yokuntuleka kwamafutha nokugaya okomile ngezikhathi ezithile, okubangela ukwehluleka kwebheringi; uma inani lokwengeza liningi kakhulu, igrisi yokugcoba izoshiswa ngokuxubha futhi ibangele ukwehluleka kwebheringi, futhi izophinde ibe mncane futhi ichithe ukuze ingcolise ingaphakathi lemoto.
