Ukugunyazwa kwangempela kwe-motor ezithwalaemsebenzini kuhlobene nomthwalo othwalayo, isivinini, ukuthambisa, ukukhuphuka kwezinga lokushisa, ukudlidliza, ukwakheka kokuklama kanye nokuqina kwendawo yetafula elihambisanayo.Lapho ukhetha, kufanele kukhethwe ngokuya ngesimo esithile.Ukukhishwa ngemva kokukhipha ukunwetshwa noma ukufinyezwa kwendandatho ngenxa yokulingana kokuphazamiseka lapho i-bearing ifakwe ku-shaft noma endlini ibizwa ngokuthi "i-installation clearance" kusukela kumvume yethiyori.Ukugunyazwa okutholwe ngokungeza nokukhipha ukuhluka kobukhulu ngenxa yomehluko wezinga lokushisa ngaphakathi kwebhere kusuka ku-mounting clearance kubizwa ngokuthi "i-effective clearance".Ukuvunyelwa lapho ukuthwala kufakwe emshinini ngaphansi komthwalo othile futhi kuzungeza, okungukuthi, imvume ngemuva kokuvunyelwa okusebenzayo kanye nokuguqulwa kwe-elastic okubangelwa umthwalo othwalayo kubizwa ngokuthi "imvume yokusebenza".
Njengoba kuboniswe emfanekisweni, lapho imvume yokusebenza ingalungile kancane, impilo yokukhathala ye-bearing yinde kakhulu, kodwa impilo yokukhathala iyancipha kakhulu ngokunyuka kwemvume engalungile.Ngakho-ke, lapho ukhetha i-bearing clearance, ngokuvamile kuyatuseka ukwenza imvume yokusebenza ibe yiziro noma ibe yinhle kancane.Uma ukhetha ukuthwala imvume, izici ezilandelayo kufanele zicatshangelwe: 1. Izimo zokusebenza zokuthwala, njengomthwalo, izinga lokushisa, isivinini, ukudlidliza, njll.;2. Izidingo zokusebenza kwe-bearing (ukunemba kokujikeleza, i-torque yokungqubuzana, ukudlidliza, umsindo);3. Lapho ukuthwala, i-shaft kanye nembobo yezindlu kusesimweni sokuphazamiseka, imvume yokuthwala iyancipha;4. Uma i-bearing isebenza, umehluko wokushisa phakathi kwamasongo angaphakathi nangaphandle ubangela ukwehla kwe-bearing clearance;5. Ngenxa yokwandiswa kwama-coefficients ahlukene we-shaft nezinto zezindlu , okubangela ukuba imvume yokuthwala iyancipha noma ikhule.
Ngokusho kokuhlangenwe nakho, imvume yokusebenza efanele kakhulu yama-ball bearings iseduze ne-zero, futhi inani elincane lemvume yokusebenza kufanele ligcinwe kuma-roller bearings.Ezingxenyeni ezidinga ukuqina okuhle kokusekela, ukuthwala kuvunyelwe ukuba nenani elithile lokulayisha kuqala.Ngaphansi kwezimo ezijwayelekile zokusebenza, iqembu eliyisisekelo kufanele likhethwe, ukuze ukuthwala kungathola imvume yokusebenza efanele.Lapho iqembu eliyisisekelo lingakwazi ukuhlangabezana nezidingo zokusetshenziswa, imvume yeqembu elisizayo kufanele ikhethwe.Iqembu elikhulu le-clearance assist lifanele ukuhlangana kokuphazamiseka phakathi kwe-bearing kanye ne-shaft kanye ne-bore yezindlu.Iqembu elincane elisizayo lokususa imvume lifanele izikhathi ezidinga ukunemba okuphezulu kokujikeleza, ukulawulwa okuqinile kokugudluzwa kwe-axial yembobo yezindlu, nokunciphisa ukudlidliza nomsindo.Ukwengeza, lapho ukuqina kwe-bearing kudinga ukuthuthukiswa noma umsindo udinga ukuncishiswa, imvume yokusebenza kufanele ithathe elinye inani elibi, futhi lapho izinga lokushisa elithwala likhuphuka kakhulu, imvume yokusebenza kufanele ithathe elinye inani elihle, njll. ., futhi ukuhlaziya okuthile kufanele kwenziwe ngokuvumelana nezimo zokusebenza..
Njengoba imvume yokusebenza ihlobene eduze nokuphila, ukuphakama kwezinga lokushisa, ukudlidliza kanye nomsindo wokuthwala, ukulawulwa kwemvume yangaphakathi yokuthwala kubaluleke kakhulu.Ama-motor bearings kufanele abe nemvume yangaphakathi efanele ukuze agcine ukusebenza kahle.Ukucaciswa kokuqala kwe-bearing kuyinkomba ebaluleke kakhulu.Ngakho-ke, ngaphambi kokuba kuhlanganiswe ukuthwala, i-feeler gauge kufanele isetshenziselwe ukuhlola imvume yokuqala, futhi ngesikhathi esifanayo, ukumelana nokuxhumana phakathi kwendandatho yangaphakathi kanye ne-armature shaft kufanele kulinganiswe ukuze kuqinisekiswe ukuthintana kwayo okuthembekile.Ngemuva kokuthi i-motor iqoqwe, imvume yokuthwala iyimvume ehambisanayo.Uma imvume incane kakhulu ngalesi sikhathi, kuzokwenza ukuthi ukuthwala kudlulele, kubangele indandatho yangaphakathi ukuba ikhule, yenza imvume ibe yincane futhi ibe yincane, futhi ekugcineni ibangele ukushisa;Uma kukhulu kakhulu, ama-roller azocindezelwa ngokungalingani, okuholela ekudlidlizeni okwengeziwe, okulula ukulimaza ukuthwala.Ngakho-ke, ngemva kokuhlanganiswa okuphelele kwe-motor, i-gauge yokuzizwa kufanele isetshenziselwe ukukala ukucaciswa kwe-bearing ngemva kokuhlanganiswa.Uma imvume itholakala ingafaneleki, kufanele ihlakazwe futhi ilungiswe.Ukucaciswa kwe-radial kwasekuqaleni kwamabheringi e-ZWZ konke kuhambisana ne-GB4604.Amanani e-radial clearance asebenza kuma-bearings angehlisiwe futhi angalayishiwe.Amabhere amakhulu noma amancane kunenani elijwayelekile lokuvunyelwa nawo angakhiqizwa ngokuya ngezidingo zomsebenzisi.
