Indlela yokukhetha phakathi kwee-Needle Roller Bearings eziKhaphukhaphu, eziphakathi, kunye nezinzima

 

Iibheringi zerola yenalitizisetyenziswa kakhulu kwiinkqubo zothumelo lwemishini ngenxa yomthamo wazo ophezulu womthwalo kunye noyilo oluncinci. Nangona kunjalo, xa zijongene noluhlu olubanzi lweemodeli zemveliso, ukukhetha i-bearing efanelekileyo yeyona nto iphambili kwiinjineli.

Eli nqaku ligxile kuthotho oluqhelekileyo lwe-48/49 kunye ne-69iibheringi zerola yenalitiNgokudibanisa iiparameters ezinobukhulu kunye neempawu zesakhiwo, ihlalutya nzulu umahluko ophambili phakathi kwezi zimbini ekusebenzeni kokuthwala umthwalo, uyilo lwesakhiwo, kunye neemeko zesicelo, inceda ukufanisa ngokuchanekileyo iimfuno zoyilo.

 

Ngokwendlela eqhelekileyo yokuchonga uthotho olunemilinganiselo, uthotho lwe-48/49 luhlelwa njenge-"light-medium," ngelixa uthotho lwe-69 luchazwa ngokucacileyo njenge-"heavy." Olu hlu lubonakaliswa kungekuphela nje kwindlela yokubiza amagama kodwa nakwindlela esebenza ngayo ngokwenene iibheringi.

 

Ngokwembono yesakhiwo, uthotho lwe-69 lubonisa iingenelo ezibalulekileyo kwiimilinganiselo eziphambili. Amaphepha edatha abonisa ukuba ububanzi bendandatho yangaphakathi (i-Bo) yeebheringi zechungechunge lwe-69 ngokubanzi bukhulu kunobo bothotho lwe-49 olufanayo.iibheringiOku kuthetha ukuba iirola zinde kwaye zinendawo enkulu yokunxibelelana, nto leyo ephucula ngempumelelo umthamo womthwalo we-radial. Olu luhlu lwama-69 lukwanomlinganiselo omkhulu we-chamfer (rsmin), nto leyo ebonisa isakhiwo sekona esomeleleyo esimelana ngcono noxinzelelo lokufakelwa kunye nemithwalo yokutshatyalaliswa kokusebenza, nto leyo ephucula ukuqina kwayo iyonke.

 

Xa kuthelekiswa, uthotho lwe-48/49 luncinci kwaye lukhaphukhaphu, nto leyo eyenza ukuba zifaneleke kwiindawo ezixineneyo ezinemithwalo ephakathi. Ububanzi bazo obuncinci buzenza zibe luncedo kwiindawo ezibuthathaka njengeebhokisi zegiya, iimoto ezincinci, kunye nezixhobo zeofisi. Nangona kunjalo, ngenxa yobunzima bobude berola kunye nobukhulu beendawo ezinqamlezileyo, umthamo wazo wokugqibela womthwalo uphantsi, nto leyo ebenza bangafaneleki kwiindawo ezixineneyo okanye kwiindawo ezinobungozi obukhulu.

 

Olu luhlu lwe-69, olunoyilo olunzima, luyilelwe ngokukodwa ukusetyenziswa komthwalo ophezulu, oluphantsi ukuya koluphakathi. Lusetyenziswa rhoqo kwizicelo ezifuna ukuthembeka okuphezulu kakhulu, njengoomatshini bokwakha, izixhobo zesinyithi, kunye neeshafti zokuqhuba ezinzima. Izakhiwo zalo zeringi zangaphakathi nezangaphandle eziqinisiweyo kunye nolwandiso olude.i-needle rolleruyilo luqinisekisa ukusebenza okuzinzileyo nokuba phantsi kwemithwalo enzima eqhubekayo.

 

Iingcebiso zokukhetha:

 

Ukuba indawo yezixhobo incinci kwaye imithwalo iphakathi kwaye izinzile, cinga ngoluhlu lwe-48/49, olubonelela ngokulinganisela kokusebenza kunye nokuxinana.

 

Ukuba indawo yokusetyenziswa ibandakanya imithwalo enzima, ukutshayiswa, okanye ifuna ubomi obude, khetha uthotho lwe-69 ukuqinisekisa amandla olwakhiwo kunye nokuthembeka kokusebenza.

 

Uthotho lwe-48/49 kunye ne-69iibheringi zerola yenalitiazingomahluko nje wemodeli; endaweni yoko, ziimveliso ezisebenzayo ezenzelwe ukuhlangabezana neemfuno ezahlukeneyo zokusebenza. Ukuqonda intsingiselo yobunjineli emva kweempawu zazo zoluhlu olunemilinganiselo kunye nokuqwalasela umthwalo wokwenyani, indawo, kunye neemfuno zobomi kuya kukunceda wenze ukhetho olufanelekileyo.
