Bearings z’omupiira okusinga zigabanyizibwamu ebika bisatu: deep groove ball bearings, angular contact ball bearings, ne thrust ball bearings.
Ball bearings kika kya bbeeri ekitera okukozesebwa mu byuma eby’ebyuma era nga zikozesebwa nnyo mu nnimiro ez’enjawulo ez’amakolero. Okusinziira ku nsengeka yazo n’engeri gye bikozesebwamu, bbeeri z’omupiira zigabanyizibwa mu biti bino wammanga:
1. Deep Groove Ball Bearings .
Deep groove ball bearings ye bbeeri ekiikirira rolling nga erimu enkola ez’enjawulo. Okusinga ziwagira emigugu gya radial, naye era zisobola okugumira emigugu egimu egy’ekyekulungirivu. Radial clearance ya bearing bwe yeeyongera, ziraga omulimu gwa angular contact ball bearings era zisobola okugumira emigugu eminene egy’ekyekulungirivu. Ekirala, bbeeri zino zirina omutendera ogugere ogw’okwefuula-era zikyayinza okukola mu ngeri eya bulijjo nga ziwanvuye 2’ okutuuka ku 10’ okusinziira ku kifo ky’ennyumba, wadde nga kino kirina akakwate akamu ku bulamu bwa bbeeri. Deep groove ball bearing cages zisinga kuba stamped steel nga zirina corrugated shape, ate nga ne bearings ennene zitera okukozesa ebyuma ebyuma ebigumu ebiyumba.
2. Bearings z’omupiira ogw’okukwatagana mu nkoona .
Angular contact ball bearings zisobola okuwanirira emigugu gyombi egya radial ne axial, oba emigugu egy’ekyekulungirivu gyokka. Zirina sipiidi esinga obunene era zisobola okuwagira emigugu gyombi egya radial ne axial, wamu n’emigugu egy’ekyekulungirivu (pure axial loads). Obusobozi bwazo obw’omugugu ogw’ekyekulungirivu busalibwawo enkoona y’okukwatagana era bweyongera nga enkoona y’okukwatagana yeeyongera. Single-Row Angular Contact Ball Bearings zisobola okuwanirira emigugu egy’ekyekulungirivu gyokka mu ludda lumu. Nga tuwagira emigugu gya radial, empalirizo endala ez’ekyekulungirivu zikolebwa, nga zeetaaga omugugu ogw’okudda emabega ogukwatagana okusobola okukozesebwa. N’olwekyo, okutwalira awamu bbeeri zino zikozesebwa bibiri bibiri. Double-Bearings z’omupiira ez’enjuba ez’enjuba zisobola okugumira emigugu eminene egy’omugatte egy’omugatte n’egya axial n’emigugu gya momenti, okusinga emigugu gya radial. Ziyinza okukomya okusengulwa kw’ekikondo oba ennyumba mu ngeri bbiri (bidirectional axial displacement) era nga zirina enkoona y’okukwatagana eya diguli 30.
Eky'okusatu. Bbeeri z'omupiira ezisindiikiriza .
Bbeeri z’omupiira ezisindikiddwa (thrust ball bearings) ze bbeeri ezisobola okwawulwamu. Ekyuma eky’okwoza engoye n’ekyuma eky’okunaaba mu ntebe bisobola okwawulwa ku kisenge ky’omupiira n’ekyuma ekikuŋŋaanyizibwa, ekifuula ebyangu okuteeka n’okukutula. Bbeeri z’omupiira ezisonseka zirimu ekyuma eky’okwoza, emipiira, n’ekiyumba. Ekintu ekisindiikiriza nti kikwatagana n’ekikondo kiyitibwa ekyuma eky’okunaaba ekikonde, ate entebe z’okunaaba n’entebe n’ennyumba. Thrust ball bearings zisobola okuwanirira emigugu egy’ekyekulungirivu gyokka. Single-Bearings z’omupiira ezisindikiddwa mu ndagiriro zisobola okuwanirira emigugu egy’ekyekulungirivu gyokka mu ludda olumu, ate nga bbeeri z’omupiira ezisindika emirundi ebiri-esobola okuwanirira emigugu egy’ekyekulungirivu mu njuyi zombi. Tezisobola kukwata migugu gya radial. Thrust ball bearings nazo zirina ekizimbe nga kiriko pad y’entebe. Okuva ekifo we bateeka paadi y’entebe bwe kiri ekyekulungirivu, bbeeri erina omulimu gw’okukwatagana-eyinza okukendeeza ku nkozesa y’ensobi z’okuteeka.
