Ezi zinto zilandelayo kufuneka ziqwalaselwe xa kukhethwa isiphelo esisisigxina senkxaso yokuthwala i-motor (ebizwa ngokuba yi-motor fixed end): (1) iimfuno zolawulo oluchanekileyo lwezixhobo eziqhutywayo; (2) uhlobo lomthwalo oqhutywa yinjini; (3) i-axial force ethile kufuneka ikwazi ukumelana ne-axial force ethile. Ngokusekwe kule miba mithathu ingentla yoyilo, iibheringi zebhola zegroove ezinzulu zihlala zisetyenziswa njengokhetho lokuqala lokuthwala isiphelo semoto esincinci kwayeiinjini zobungakanani obuphakathi.
Iibheringi zebhola ze-deep groove zezona zisetyenziswa ngokuqhelekileyo iibheringi eziqengqelekayo. Xa i-deep groove ball bearings isetyenziswa, isakhiwo senkqubo yokuxhasa i-motor ilula kakhulu kwaye kulula ukuyigcina. Iibhodi zebhola ze-groove ezinzulu zisetyenziselwa ukuthwala imithwalo ye-radial, kodwa xa ukukhutshwa kwe-radial ye-bearing kunyuswa, baneempawu zokudibanisa iibhola ze-angular kwaye zinokuthwala imithwalo edibeneyo ye-radial kunye ne-axial; xa isantya siphezulu kwaye iibheringi zebhola zokuphola azifanelekanga, zingasetyenziselwa ukuthwala imithwalo ye-axial ecocekileyo. Xa kuthelekiswa nezinye iintlobo zeebherethi ezineenkcazo ezifanayo kunye nemilinganiselo efana ne-deep groove ball bearings, olu hlobo lokuthwala lunenzuzo ye-coefficient ephantsi ye-friction kunye nesantya esiphezulu somda, kodwa ukungahambi kakuhle kukuba ayinayo impembelelo kwaye ayifanelekanga ukuthwala imithwalo enzima.
Emva kokuba i-deep groove ball bearing ifakwe kwi-shaft, ukulungelelaniswa kwe-radial ye-shaft okanye indlu kumacala omabini kunokunqunyulwa ngaphakathi kwe-axial clearance range ye-bearing. Kwicala le-radial, i-bearing kunye ne-shaft ithatha ukulungelelaniswa kokuphazamiseka, kwaye i-bearing kunye ne-end cover covering room okanye indlu yamkela ukungenelela okuncinci. Eyona njongo iphambili yokukhetha le nto ifanelekileyo kukuqinisekisa ukuba ukucaciswa kokusebenza kwe-bearing ngu-zero okanye kubi kancinci ngexesha lokusebenza kwemoto, ukwenzela ukuba ukusebenza kwe-bearing kube ngcono. Kwisalathiso se-axial, ukulungelelaniswa kwe-axial yendawo yokubeka kunye neendawo ezinxulumene nazo kufuneka zimiselwe ngokudibanisa neemeko ezithile zenkqubo yokuthwala isiphelo esidadayo. I-ring yangaphakathi ye-bearing inqunyelwe yinqanaba lokukhawulela isikhundla (igxalaba) kwi-shaft kunye nentsimbi yokugcina i-ring, kwaye i-ring yangaphandle ye-bearing ilawulwa ngokunyamezelwa okufanelekileyo kwe-bearing kunye ne-bearing chamber, ukuphakama kokumisa izigubungelo zangaphakathi kunye nezangaphandle zokuthwala, kunye nobude begumbi lokuthwala.
(1) Xa isiphelo esidadayo sikhetha ibherethi eyahlukanayo kunye namakhonkco angaphakathi nangaphandle, amakhonkco angaphandle eebheringi kuzo zombini iziphelo ahambelana nokungabikho kwe-axial clearance.
(2) Xa isiphelo esidadayo sikhetha i-bearing engenakuhlukaniswa, ubude obuthile be-axial clearance bushiywe phakathi kwendandatho yangaphandle ye-axial kunye nokumisa isigqubuthelo sokukhusela, kunye nokulingana phakathi kweringi yangaphandle kunye negumbi lokuthwala akufanele kube nzima kakhulu.
(3) Xa i-motor ingenasiphelo esicacileyo sokumisa kunye nesiphelo esidadayo, iibherengi zebhola ze-groove ezinzulu zisetyenziswa ngokubanzi kuzo zombini iziphelo, kwaye ubudlelwane obufanelekileyo kukuba i-ring yangaphandle ye-axial bear itshixiwe kunye nesigqubuthelo sangaphakathi kwaye kukho umsantsa phakathi kweringi yangaphandle kunye nesigqubuthelo sangaphandle kwicala le-axial; okanye umsesane wangaphandle weebheringi kwiziphelo zombini uhambelana nokungacocwa kwe-axial phakathi kweringi yangaphandle yebheringi kunye nesigqubuthelo sokuthwala, kwaye kukho umsantsa phakathi kweringi yangaphandle kunye nesigqubuthelo sangaphakathi kwicala le-axial.
Olu budlelwane bungasentla buthelekiseka bubonke ubudlelwane obufanelekileyo buhlalutywa ngokwethiyori. Ukucwangciswa kwangempela kokuthwala kufuneka kuhambelane neemeko zokusebenza zemoto, kubandakanywa iiparitha ezithile ezifana nokucocwa, ukuchasana nokushisa, ukuchaneka, njl njl kwi-motor yokukhetha i-motor, kunye nobudlelwane obuhambelana ne-radial phakathi kwentsimbi kunye negumbi lokuthwala.
Kufuneka kuqatshelwe ukuba uhlalutyo olungentla lwenzelwe kuphelaiimotor ezifakwe ngokuthe tye, ngelixa iinjini ezifakwe ngokuthe nkqo, zombini ukukhethwa kweebheringi kunye nobudlelwane obuhambelanayo obuhambelanayo kufuneka kube neemfuno ezithile.
