Uhlalutyo olupheleleyo lweeModeli zeNeedle Roller Bearing

Iibheringi zerola yenalitizisetyenziswa kakhulu kuyilo lwezixhobo zoomatshini kunye nokugcinwa kwezixhobo ngenxa yomthwalo wazo ophezulu kunye noyilo oluncinci. Nangona kunjalo, iingcali ezininzi kunye neenjineli zokuthengisa zisadidekile ngamagama amaninzi eemodeli, kuquka i-NATR, i-NAKD, kunye ne-KR. Eli nqaku, elisekelwe kwi-GB/T 272 esemgangathweni kazwelonke, "Indlela yokuBearing Designation," libonelela ngohlalutyo olunzulu lwe-needle roller bearing designation logic, inceda iingcali ukuba zikwazi ukukhetha ngokukhawuleza iindlela.

 

1. Ukuchaza iSihlomelo esiPhambili: Intsingiselo yeziQalo kunye neeModeli eziSiseko

 

I-Needle roller bearingIimodeli azinikwa ngokungacwangciswanga; zilandela imithetho engqongqo yokubhala iikhowudi. Uyilo oluphambili ludla ngokuba "nophawu olusisiseko" olulandelwa sisimamva, apho uphawu olusisiseko lutyhila uhlobo lokuthwala kunye neempawu zesakhiwo.

 

Uthotho lwe-NA: imele iibheringi zerola yeenaliti ezingenandandatho yangaphakathi. Ezi bearing zisebenzisa ijenali yeshaft njengendlela yokukhwela indandatho yangaphakathi, zigcina indawo kwaye zifanelekile ukusetyenziswa ngemiphezulu yeshaft eqinileyo.

 

Uthotho lwe-NK: iibheringi ze-needle roller ezine-inner ring zibonelela ngesakhiwo esizinzileyo ngakumbi kwaye zifanelekile kwisantya esiphezulu okanye xa izinto ze-shaft zingakulungelanga ukusebenza ngqo kwindlela yokugijima.

 

Uthotho lwe-KR: Ichaza ngokukodwa iibheringi zeenaliti zerola ezineeshafti ezineebholti. Zisetyenziswa kakhulu ekuthuthweni kwezixhobo kunye neenkqubo zesikhokelo seeroli, zibonelela ngokufakelwa okulula kunye nomthwalo ophezulu.

 

I-NATR / i-NATV:Ezi ziibheringi zeenaliti ezineringi yangaphandle ejikelezileyo kwaye azinaringi yangaphakathi. I-TR ichaza iringi yangaphandle ejikelezileyo kunye noyilo olufumana indawo yokutyhala, ngelixa i-V imele ukongeza okupheleleyo kweenaliti ezijikelezileyo (ezingenakheji). Zifanelekile kwisantya esiphantsi kunye nemithwalo enzima.

 

Icebiso: Ukwahlula ukuba i-bearing ine-ring yangaphakathi na linyathelo lokuqala ekukhetheni i-bearing. Iintlobo ezingenayo i-ring yangaphakathi zibonelela ngeendleko eziphantsi kunye nobukhulu obuncinci be-radial, kodwa zifuna ubulukhuni obuphezulu bomngxuma kunye nomgangatho womphezulu.

 

II. Ikhowudi yesihlomelo: Itywina, iKheji, kunye nohlobo lweRingi yangaphandle

 

Ileta yesimamva ichaza ngakumbi iimpawu zokusebenza kwebhereyi kwaye ichaphazela ngokuthe ngqo imeko yokusebenza kunye nobomi bayo.

 

Isihlomelo sentsingiselo

 

-2RS Izitywini zerabha ezimacala mabini: Zimelana nothuli namanzi, zifanelekile kwiindawo ezifumileyo okanye ezinothuli.

 

-Z Isigqubuthelo sothuli sepleyiti yentsimbi esicala linye: Sikhusela kwiisuntswana ezinkulu kwaye sinikezela ngokusebenza okuphezulu kakhulu xa kuthelekiswa neemodeli ezivaliweyo.

 

Isangqa sangaphandle se-X Cylindrical (esingeyo cam): Sifanelekile kwizicelo ezifuna ukuchaneka okuphezulu kokubekwa.

 

Ikheyiji yeTV Polyamide: Yehlisa ubunzima kwaye yonyusa isantya esiphezulu.

 

Umzekelo, i-NA4904-2RS ibonisa i-needle roller bearing enobubanzi obuyi-20mm ngaphandle kweringi yangaphakathi, exhotyiswe nge-rubber seals enamacala amabini. Ifanelekile kwiimoto ezincinci okanye kwiibhokisi zegiya.

 

3. Ungazifanisa njani iiModeli ngokukhawuleza? Indlela yokukhetha amanyathelo amathathu

 

Misela iimfuno zesakhiwo: Ngaba iflange iyimfuneko ukuze ufumane indawo? Ngaba ishaft ivumelekile ukuba isebenze njengendawo yokugijima?

 

Jonga itafile enobukhulu: Khetha imodeli esisiseko esekelwe kwindawo yokufaka (ububanzi bangaphakathi, ububanzi bangaphandle, kunye nobubanzi).

 

Yongeza izimamva ngokusekelwe kwiimeko zokusebenza: Cinga ngezinto ezinje ngokutywina, ukuthambisa, kunye nesantya ukuze ukhethe uhlobo olufanelekileyo.

 

Kucetyiswa ukuba uthelekise umzobo wesakhiwo esinqamlezileyo kwincwadana yemveliso kunye netafile yeeparameter ezinobukhulu ukuze uqonde ngokucacileyo isakhiwo sangaphakathi kunye nendlela yokufakela.

 

Ukuqonda kakuhle inkqubo yokumiselaiibheringi zerola yenalitiAkubonisi nje kuphela ubuchule bobuchwephesha kodwa kubalulekile ekuphuculeni ubuchule benkonzo. Ukuqonda ingqiqo yobunjineli emva kweempawu ezifana ne-NA, KR, kunye ne-2RS kunokuphucula kakhulu ukhetho, ukuthengwa, kunye nokusombulula iingxaki.
