Iibheringi zeRoller eziSikwere
Iibheringi zerola ezingqukuva ziyinxalenye ebalulekileyo kumatshini onzima wemizi-mveliso, zinoyilo oluntsonkothileyo lwerola enemigca emibini oluzahlula kwizisombululo zerola eziqhelekileyo. Isangqa sangaphandle senziwe ngendlela enye yokwahlulwa kwerola, ngelixa isangqa sangaphakathi sineendlela ezimbini zokwahlulwa ezichanekileyo ezithe tye kwi-engile ethile xa kuthelekiswa ne-axis ephakathi yebhereyi. Olu lwakhiwo olunobuchule luyisiseko sendlela yazo yokusebenza egqwesileyo, luzinika amandla okuzilungelelanisa angaphakathi azenza zikwazi ukumelana kakhulu nokungahambi kakuhle kwe-axial, ukuphambuka kwe-engile yendlu yeebheringi, kunye nokugoba kweshaft.
Ngokungafaniyo neebheringi zesiqhelo ezinengxaki yokungachaneki kofakelo, iibheringi zerola ezingqukuva ziyabalasela kwiindawo apho iimpazamo ze-angular zingenakuphepheka ngenxa yokuphambuka kweshaft okanye ukulungelelaniswa okungafanelekanga kwendlu, okuqinisekisa ukusebenza okuzinzileyo nakwiimeko ezinzima zokuhlanganisa.
Enye yezona mpawu zibalulekileyo zeebheringi zerola ezingqukuva kukusebenza kwazo okuphezulu kokuzilungelelanisa. Indlela yokubaleka engqukuva kwiringi engaphandle ivumela iringi yangaphakathi kunye neerola ezimile okwebharele ukuba zijikeleze kakuhle, zihlawulela ngokuzenzekelayo ukungahambi kakuhle kweshaft ukuya kuluhlu oluthile— uphawu oluyimfuneko kwiimashini ezinzima apho ukulungelelaniswa okugqibeleleyo kuhlala kunzima ukulugcina.
Okuzalisa oku kukuthwala kwazo umthwalo ophezulu kakhulu: umqolo ophindwe kabini weerola ezimile okwebharele usasaza ubunzima ngokulinganayo kwindawo enkulu yoqhagamshelwano, nto leyo ebavumela ukuba bakwazi ukusingatha ngokufanelekileyo imithwalo enzima yeradial, amandla amakhulu okutshayelwa, kwanemithwalo edibeneyo yeradial kunye ne-axial. Olu yilo luqinileyo luqinisekisa ukuba zinokumelana neemfuno ezinzima zemisebenzi yemizi-mveliso ngaphandle kokubeka emngciphekweni ukusebenza okanye ukuqina.
Iingenelo zeebheringi ezijikelezayo zenza ukuba zibe lukhetho olukhethwayo kwiimveliso zoshishino kwihlabathi liphela. Ubomi bazo obude buyinzuzo ebalaseleyo, ngakumbi kwiinguqulelo ezivaliweyo ezenzelwe ukuthintela ungcoliseko oluvela kuthuli, ukungcola, kunye nokufuma— uphawu olubalulekileyo kwiindawo zoshishino ezinzima apho inkunkuma inokunciphisa kakhulu ubomi beebheringi.
Iibheringi zerola ezitywiniweyo nazo zifuna ukugcinwa okuncitshisiweyo, njengoko ziza sele zithanjiswe kwaye zisusa isidingo sokuthambisa rhoqo, nto leyo enciphisa ixesha lokungasebenzi kunye neendleko zokusebenza.
Ukuguquguquka kwazo yenye inzuzo ephambili: ziyakwazi ukusingatha imithwalo ephezulu ye-radial kunye ne-axial edibeneyo ngaphandle kokuphazamiseka, nto leyo eyenza zifaneleke kwiindidi ezahlukeneyo zezicelo ngaphandle kwesidingo see-bearings ezikhethekileyo. Ngaphezu koko, ulwakhiwo lwazo oluqinileyo luqinisekisa ukumelana nokuguguleka, nokuba kusetyenzwa rhoqo ngemithwalo enzima, okubonelela amashishini ngezisombululo ze-bearings ezinokuthenjwa nezingabizi kakhulu eziphucula ukusebenza koomatshini ngokubanzi.
