Imikhiqizo yezimoto enama-bearings, ngendima yezingxenye ezihambisanayo, kokubili ohlangothini lwe-radial kanye ne-axial ingaphansi kwemingcele yokubeka, umphumela wayo uzoba nomthelela ekususweni kwe-bearings, okubonakala ekususweni kokuqala kwe-bearings kanye nomehluko phakathi kwe-imvume yokusebenza.
Isikhala esisebherini yibanga eliphelele elingase lihanjiswe yinye yezindandatho zokuthwala ngendlela ye-radial noma ye-axial uma kuqhathaniswa nenye indandatho yokuthwala. Ngokuphathelene nesikhala sebherini, kufanele kwenziwe umehluko phakathi kwesikhala ngaphambi kokufakwa kanye nesikhala ngemva kokufakwa kanye nokufinyelela izinga lokushisa lokusebenza. Isikhala sokusebenza sebherini ngokuvamile sincane kunesikhala sokuqala ngenxa yokubekezelelana okuhambisana namanani ahlukene okuphazamiseka kanye namazinga ahlukene okwanda kokushisa kwezindandatho zokuthwala kanye nezingxenye ezihambisanayo (isb. ama-motor shafts, ama-end caps, njll.), okuholela ekwandeni noma ekucindezelweni kwendandatho.
Izimiso ezijwayelekile zokulawula kanye nobuchwepheshe: Isikhala sokusebenza sama-ball bearings kufanele sibe yi-zero noma sibe nomthwalo omncane kusengaphambili. Kodwa-ke, kuma-cylindrical roller, ama-spherical roller kanye namanye ama-bearings, kumele kube nesikhala esithile esisele esisebenzayo, noma ngabe sincane kakhulu.
Ngokuvamile ngaphansi kwezimo zokusebenza ezijwayelekile, imvume yokusebenza efanelekile ingatholakala ngokukhetha amabheringi anemvume evamile yeqembu. Kodwa-ke, umaizimo zokusebenza nezokufakazihlukile esimweni esijwayelekile, njengokuthi amabheringi womabili ahambisana nokuphazamiseka, noma umehluko wokushisa kwendandatho unethonya elikhulu, khona-ke indawo yokuvula kufanele ikhethwe kuneqembu elijwayelekile lamabheringi amakhulu noma amancane.
Kuye ngesicelo, amabheringi kufanele ahlelwe nge-positive noma negative clearance yokusebenza. Ezimweni eziningi, i-working clearance kufanele ibe ne-positive, okungukuthi i-bearing kufanele isebenze nge-residue clearance ethile. Ngakolunye uhlangothi, kunezinhlelo zokusebenza eziningi lapho kudingeka i-negative working clearance - okungukuthi i-preload -.
Ukulayisha kusengaphambili ama-bearings kungasetshenziswa ukwandisa ukuqina noma ukunemba kokujikeleza kokucushwa kwama-bearings. Izibonelo zifaka phakathi ama-spindle bearings kumathuluzi omshini, ama-pinion bearings kuma-driveshaft ezimoto, ama-bearings kuma-motor amancane, noma ukucushwa kwama-bearings kokunyakaza okuphindaphindayo. Kwezinye izinhlelo zokusebenza lapho ama-bearings engekho, noma kuphela, ngaphansi kwemithwalo emincane kakhulu futhi asebenza ngesivinini esiphezulu, ukulayisha kusengaphambili kufanele kusetshenziswe ku-ukucushwa kokuthwalaKulokhu, inhloso yokulayisha kusengaphambili ukunikeza umthwalo omncane kubhereyi ukuze kuvinjelwe izinto ezigoqekayo ukuthi zingasheleli futhi zibangele umonakalo kubhereyiyi.
Ukulayisha kusengaphambili kungaba yi-radial noma i-axial kuye ngohlobo lwe-bearing. Ama-roller bearings e-cylindrical, isibonelo, angafakwa kuphela ukulayisha kusengaphambili ohlangothini lwe-radial ngenxa yomklamo wawo, kuyilapho ama-thrust ball bearings kanye nama-cylindrical roller thrust bearings angafakwa kuphela ukulayisha kusengaphambili ohlangothini lwe-axial. Ama-single row angular contact ball bearings kanye nama-tapered roller bearings ngokuvamile afakwa ku-axial preload futhi avame ukusetshenziswa kuma-back-to-back pairs noma ubuso nobuso nge-bearing enye yohlobo olufanayo. Ama-deep groove ball bearings avame ukusetshenziswa nokulayisha kwangaphambili okufanayo kwe-axial, ukuze kufezwe injongo yokulayisha kusengaphambili, kufanele kusetshenziswe neqembu elikhulu kunelijwayelekile le-radial internal clearance, ukuze kube njengokuthi ama-angular contact ball bearings ane-contact angle engaphezu kuka-zero.
