Ukukhethwa kwesiphelo esisisigxina sokuxhaswa kwemoto (esibizwa ngokuba yisigxina), ezi zinto zilandelayo kufuneka ziqwalaselwe: (1) Iimfuno zokulawula ngokuchanekileyo izixhobo eziqhutywayo;(2) Ubume bomthwalo wemoto drive;(3) Ukuzala okanye ukuzala inhlanganisela Kufuneka ikwazi ukumelana ne-axial force ethile.Ukudibanisa izinto zoyilo zale miba mithathu ingasentla, kwiimotor ezincinci kunye nobungakanani obuphakathi, iibherengi zebhola zegroove ezinzulu zihlala zisetyenziswa njengokhetho lokuqala lweebheringi ezisisigxina zemoto.
Iibheringi zebhola ze-deep groove zezona zisetyenziswa ngokuqhelekileyo iibheringi eziqengqelekayo.Xa usebenzisa i-deep groove ball bearings, isakhiwo senkqubo yokuxhasa i-motor silula kakhulu, kwaye ukugcinwa kulungeleka.Iibhodi zebhola ze-deep groove zisetyenziselwa ukuthwala imithwalo ye-radial, kodwa xa ukukhutshwa kwe-radial ye-bearings kunyuswa, baneempawu zokudibanisa iibhola ze-angular kwaye zinokuthwala imithwalo edibeneyo ye-radial kunye ne-axial;Iibhola ezityhalwayo azifanelekanga kwizantya eziphezulu Xa zisetyenziswa njengokuthwala, zinokusetyenziselwa ukuthwala umthwalo ococekileyo we-axial.Xa kuthelekiswa nezinye iintlobo zeebherethi ezinemilinganiselo efanayo kunye nemilinganiselo njengeebhodi zebhola ze-groove ezinzulu, olu hlobo lokuthwala lunenzuzo ye-coefficient encinci ye-friction kunye nesantya esiphezulu somda, kodwa ukungahambi kakuhle kukuba ayichasananga nefuthe kwaye ayifanelekanga. imithwalo enzima.
Emva kokuba i-deep groove ibhola bearing ifakwe kwi-shaft, ngaphakathi koluhlu lwe-axial clearance ye-bearing, ukulungelelaniswa kwe-radial ye-shaft okanye indlu kwiindlela zombini inokulinganiselwa.Kwicala le-radial, i-bearing kunye ne-shaft ithatha ukulungelelaniswa kokuphazamiseka, kwaye i-bearing kunye ne-end cover covering room okanye iqokobhe ithatha ukungenelela okuncinci.Injongo ephambili yokukhetha le nto ifanelekileyo kukuqinisekisa ukuba imvume yokusebenza yokuthwala i-zero okanye incinci ngexesha lokusebenza kwemoto.I-Negative, ngoko ke ukusebenza kwe-bearing kungcono.Kwisalathiso se-axial, intsebenziswano ye-axial phakathi kwendawo yokubeka indawo kunye neendawo ezihambelanayo kufuneka zinqunywe ngokudibanisa neemeko ezithile zendlela yokungafumani indawo.I-ring yangaphakathi ye-bearing inqunyelwe yi-standing position limit limit step (ihlombe le-shaft) kwi-shaft kunye nentsimbi yokugcina i-bearing, kwaye i-ring yangaphandle ye-bearing ilawulwa ngokunyamezelwa kwesigxina kunye negumbi lokuthwala, ukuphakama nobude begumbi lokuthwala, elingaphakathi nangaphandle, nobude begumbi;
(1) Xa isiphelo esidadayo sikhetha ibherethi eyahlukanayo kunye namakhonkco angaphakathi nangaphandle, amakhonkco angaphandle eebheringi kuzo zombini iziphelo athatha i-axial clearance-free fit.
(2) Xa ibherethi engahlulwahlulwayo ikhethelwe isiphelo esidadayo, ubude obuthile be-axial clearance bugcinelwe phakathi kweringi yangaphandle yebheringi kunye nomthungo wesigqubuthelo sokuthwala, kunye nokulingana phakathi kweringi elingaphandle kunye negumbi lokuthwala. akukho lula ukuba uqine kakhulu.
(3) Xa i-motor ingenasiphelo esicacileyo sokuma kunye nesiphelo esidadayo, iibheringi zebhola zegroove ezinzulu zisetyenziswa ngokubanzi kuzo zombini iziphelo, kunye nobudlelwane bentsebenziswano phakathi kweringi yangaphandle yomda kunye nesigqubuthelo sangaphakathi sibambekile, kwaye kukho i-axial. isithuba phakathi kwesigubungelo sangaphandle nesigqubuthelo sangaphandle;Okanye akukho mvumelwano i-axial phakathi kweringi langaphandle lebheringi kuzo zombini iziphelo kunye nesigqubuthelo sangaphandle sebheringi, kwaye kukho indawo evulekileyo phakathi kwesivalo sangaphakathi nesigqubuthelo sangaphakathi.
Olu budlelwane bungasentla buthelekiseka bububudlelwane obufanelekileyo obusekwe kuhlalutyo lwethiyori.Ukucwangciswa kwangempela kokuthwala kufuneka kuhambelane neemeko zokusebenza zemoto, kubandakanywa iiparitha ezithile ezifana nokucima, ukuchasana nokushisa, kunye nokuchaneka ekukhetheni iinqwelo zeemoto, kunye neebheringi.Ubudlelwane be-radial fit kunye negumbi lokuzala, njl.
Kufuneka kuqatshelwe ukuba uhlalutyo olungentla lwenzelwe kuphela iimotor ezifakwe ngokuthe tye, kodwa kwiinjini ezifakwe ngokuthe nkqo, kufuneka kubekho iimfuno ezithile malunga nokukhethwa kweebheringi kunye nobudlelwane obuhambelanayo obuhambelanayo.
