Uthotho lweeRoller Bearing
Ii-roller bearing ziinxalenye ezibalulekileyo zokuchaneka ezisetyenziswa kakhulu kwiimashini zelaphu, kwiindibano zeemoto, kwiibhokisi zegiya zoshishino, nakwiimashini ezinzima, zidlala indima ebalulekileyo ekunciphiseni ukungqubana nokuqinisekisa intshukumo egudileyo yokujikeleza. Ngokwesakhiwo, i-roller bearing eqhelekileyo ine-mandrel 1 kunye nee-bearing ezichanekileyo ezifakwe kuzo zombini iziphelo, ezenzelwe ukumelana neemeko zokusebenza ezinzima kwiindawo ezahlukeneyo zoshishino. Njengezinto eziphambili kwiinkqubo zothumelo lwemishini, ukuthembeka kwazo kuchaphazela ngokuthe ngqo ukusebenza kakuhle, ubomi, kunye nokhuseleko lokusebenza kwezixhobo zonke.
Uthotho lwee-roller bearing luhlelwe ngokwemigaqo emibini ephambili: imo kunye noyilo. Uhlu lweemilo luquka ii-roller bearing ze-cylindrical, ii-roller bearing ezi-tapered, ii-roller bearing ze-spherical, kunye nee-needle roller bearing, nganye ilungiselelwe umthwalo othile kunye neemfuno zendawo. Utshintsho loyilo lugubungela ulungelelwaniso lomqolo omnye okanye olu-double-row, uyilo olu-flanged okanye olu-non-flanged, izakhiwo ezivaliweyo okanye ezivulekileyo, zonke ezilungiselelwe ukujongana neentlobo ezahlukeneyo zemithwalo enzima ye-radial, imithwalo ye-axial, isantya esiphezulu sokujikeleza, kunye nokungahambi kakuhle kwe-shaft.
Ukuqonda iintlobo eziphambili zee-roller bearings kubalulekile ekwenzeni izigqibo zokukhetha ezinolwazi:
Iibheringi zerola ezisilinda zibalasele ekuphatheni imithwalo enzima yeradial kunye nesantya esiphezulu sokujikeleza, kwaye zinokuthwala ukufuduka okuncinci kwe-axial ngaphandle kokuba zombini iiringi zijijekile—okuzenza zilungele iirola zoomatshini belaphu kunye neeshafti zemoto zombane. Iibheringi zerola ezithambileyo zenzelwe ukuxhasa imithwalo ye-axial edibeneyo yeradial ephezulu kunye ne-single-directional, kwaye zihlala zisetyenziswa ngababini kwiihabhu zamavili eemoto kunye neebhokisi zegiya zoshishino ukulinganisela amandla amabini.
Iibheringi zerola ezijikelezayo zibalasele ngokukwazi kwazo ukusingatha imithwalo enzima yeradial, imithwalo ye-axial ejikelezayo, kunye nokulungisa ngokuzenzekelayo ukungahambi kakuhle kweshaft okubangelwa ziimpazamo zokufakelwa okanye ukuphambuka kokusebenza, okwenza zifaneleke kwizixhobo ezinzima ezifana neenkqubo zokuhambisa kunye noomatshini bokwemba. Iibheringi zerola zeenaliti, ezinolwakhiwo oluncinci kunye nomthamo ophezulu womthwalo xa kuthelekiswa nobukhulu bazo, zezona zikhethwayo kwizicelo ezinesithuba esincinci sokufakela, njengeempompo ze-hydraulic kunye neetransmissions zemoto.
Iibheringi zerola ezithungayo, kuquka neebheringi zeenaliti ezithungayo, zenzelwe ngokukodwa ukumelana nemithwalo ephezulu ye-axial, esetyenziswa rhoqo kwi-spindles zezixhobo zomatshini kunye neendlela ze-elevator.
Inkqubo yokukhetha i-roller bearing efanelekileyo ibandakanya uvavanyo olupheleleyo lweeparameter zokusebenza eziphambili:
okokuqala, chonga uhlobo kunye nobukhulu bemithwalo (i-radial, i-axial, okanye edibeneyo);
okwesibini, misela isantya sokujikeleza esifunekayo kunye nenqanaba lokuchaneka (okubalulekileyo kwizicelo ezichanekileyo kakhulu ezifana noomatshini be-CNC);
okwesithathu, cinga ngoluhlu lobushushu bokusebenza (ukukhetha iibheringi ezinezinto ezifanelekileyo ezimelana nobushushu);
kwaye ekugqibeleni, vavanya imida yendawo ukuqinisekisa ukuba ibheri ihambelana kakuhle noyilo lwesixhobo.
