Ukukhethwa kokukhutshwa kokukhutshwa kunye nokucwangciswa yinxalenye ebaluleke kakhulu yoyilo lweemoto, kwaye isisombululo esikhethiweyo ngaphandle kokwazi ukusebenza kokuthwala kunokwenzeka ukuba luyilo olungaphumeleli.Iimeko zokusebenza ezahlukeneyo zineemfuno ezahlukeneyo zeebheringi.

Injongo yokuthwala i-lubrication kukwahlula i-rolling element kunye ne-rolling surface kunye nefilimu yeoli encinci, kwaye wenze ifilimu ye-oyile yokuthambisa iyunifomu kwindawo eqengqelekayo ngexesha lokusebenza, ngaloo ndlela kuncitshiswe ukungqubana kwangaphakathi kokuthwala kunye nokunxitywa kwento nganye. ukuthintela sintering.Ukuthambisa okulungileyo yimeko efunekayo ukuze i-bearing isebenze.Uhlalutyo lwezizathu zokuthwala umonakalo lubonisa ukuba malunga ne-40% yomonakalo owenziweyo unxulumene nokuthanjiswa kakubi.Iindlela zokuthambisa zahlulwe zibe yi-lubrication yegrisi kunye ne-oyile yokuthambisa.

I-lubrication yegrisi inenzuzo yokuba ayifuni ukuzaliswa ixesha elide emva kokuzaliswa kwegrisi kanye, kwaye isakhiwo sokutywinwa silula, ngoko sisetyenziswa ngokubanzi.Igrisi sisithambisi semi-solid esenziwe nge-oyile yokuthambisa njenge-oyile esisiseko kwaye ixutywe ne-thickener eqinileyo ene-lipophilicity eyomeleleyo.Ukuze kuphuculwe ezinye iimpawu, izongezo ezahlukahlukeneyo zongezwa.Ukuthambisa i-oyile, rhoqo kubandakanya ukuthambisa ioyile ejikelezayo, ukuthambisa ngejethi, kunye nokuthambisa ngenkungu yeoli.Ioyile yokuthambisa yeebheringi ngokuqhelekileyo isekelwe kwioli ye-mineral esulungekileyo kunye nokuzinza okulungileyo kwe-oxidation kunye nokumelana nokugqwala, kunye namandla aphezulu efilimu yeoli, kodwa ioli ehlukeneyo yokwenziwa isoloko isetyenziswa.

Ukulungelelaniswa kweendawo ezijikelezayo zemoto (ezifana ne-shaft engundoqo) ngokuqhelekileyo kufuneka zixhaswe ngeesethi ezimbini zeebheringi, kwaye inxalenye ejikelezayo ibekwe i-radially kunye ne-axially ngokumalunga nenxalenye emiselweyo yomatshini (njengokuthwala. isihlalo).Ngokuxhomekeke kwimiqathango yesicelo, njengomthwalo, ukuchaneka okujikelezayo okufunekayo kunye neemfuno zeendleko, amalungiselelo okuthwala angabandakanya oku kulandelayo: Ukuthwala amalungiselelo kunye neziphelo ezisisigxina kunye neziphendu ezidadayo Amalungiselelo okuthwala alungelelanisiweyo (agxininiswe kuzo zombini iziphelo) ""I-Floating" i-finearing bear configuration ( iziphelo zombini ziyadada)

Ukuthwala isiphelo esisisigxina sisetyenziselwa ukuxhaswa kwe-radial kwelinye icala le-shaft kunye nokubekwa kwe-axial kumacala amabini ngexesha elinye.Ngoko ke, ukuthwala isiphelo esimiselweyo kufuneka kulungiswe kwi-shaft kunye nezindlu zokuthwala ngexesha elifanayo.Iibheringi ezilungele ukusetyenziswa kwisiphelo esisisigxina ziibheringi zeradial ezikwaziyo ukumelana nemithwalo edibeneyo, efana neebheringi zebhola zegroove ezinzulu, umqolo ophindwe kabini okanye umgca omnye odityanisiweyo webhola edibeneyo ye-angular, iibheringi zebhola ezizilungelelanisayo, iibheringi ezingqukuva kunye ne-roller okanye i-tapered roller bearings. .ukuzala.Iibheringi zeRadial ezinokuthi zithwale kuphela imithwalo ecocekileyo ye-radial, efana neebheringi eziqinileyo ze-cylindrical roller kunye neringi enye ngaphandle kweembambo, kunye nezinye iintlobo zeebheringi (ezifana neebheringi zebhola ze-groove ezinzulu, iibheringi zebhola zoqhagamshelwano ezine okanye iibheringi ze-bidirectional thrust) njl. kwakhona isetyenziswe ekupheleni elimisiweyo xa isetyenziswe ngokwamaqela.Kolu lungelelwaniso, enye ibherethi isetyenziselwa kuphela ukubeka i-axial kumacala amabini, kwaye iqondo elithile lenkululeko ye-radial kufuneka lishiywe kwisihlalo sokuthwala (oko kukuthi, ukukhutshwa kufuneka kugcinwe kunye nesihlalo sokuthwala).

Ukuthwala isiphelo esidadayo sisetyenziselwa kuphela ukuxhasa i-radial kwelinye icala le-shaft, kwaye i-shaft kufuneka ivunyelwe ukuba ibe ne-axial displacement ethile, ukwenzela ukuba kungabikho kunyathelana phakathi kweebheringi.Ngokomzekelo, xa ukuthwala kwanda ngenxa yokushisa, ukufuduka kwe-axial kunokuba Ezinye iintlobo zeebheringi ziphunyezwa ngaphakathi.Ukufuduka kwe-Axial kunokwenzeka phakathi kwelinye lamakhonkco okuthwala kunye nenxalenye edityaniswe kuyo, ngokukhethekileyo phakathi kwendandatho yangaphandle kunye ne-bore yezindlu.
