Cikakken Bincike Kan Samfuran Bearing Na'urar Roller Bearing

Bearings na naɗa alluraAna amfani da su sosai wajen ƙira da kula da kayan aiki saboda ƙarfin ɗaukar kaya da kuma ƙirar da ta yi ƙanƙanta. Duk da haka, yawancin masu fasaha da injiniyoyin tallace-tallace suna cikin ruɗani game da sunayen samfura iri-iri, ciki har da NATR, NAKD, da KR. Wannan labarin, wanda ya dogara da ƙa'idar GB/T 272 ta ƙasa, "Hanyar Zaɓar Bearing," yana ba da cikakken bincike game da dabarun zaɓar bearing na allura, yana taimaka wa masu aiki su ƙware dabarun zaɓi cikin sauri.

 

1. Fahimtar Asalin Sunan: Ma'anar Prefixes da Asali Models

 

Dogon allura mai nadiBa a sanya samfura bazuwar; suna bin ƙa'idodin tsare-tsare masu tsauri. Tsarin keɓancewa yawanci ya ƙunshi "ƙirar asali" sannan a biyo baya da ƙari, tare da keɓancewa na asali yana bayyana nau'in ɗaukar hoto da fasalulluka na tsarin.

 

Jerin NA: yana wakiltar bearings na allura ba tare da zoben ciki ba. Waɗannan bearings suna amfani da littafin shaft a matsayin hanyar tsere ta zoben ciki, suna adana sarari kuma sun dace da amfani da saman shaft mai tauri.

 

Jerin NK: bearings na allura masu zobe na ciki suna ba da tsari mafi kwanciyar hankali kuma sun dace da manyan gudu ko lokacin da kayan shaft bai dace da aikin tseren kai tsaye ba.

 

Jerin KR: Ya keɓance musamman bearings na allurar nadi mai ƙulli. Ana amfani da su sosai wajen jigilar kayan aiki da tsarin jirgin ƙasa mai jagora, suna ba da sauƙin shigarwa da ɗaukar kaya mai yawa.

 

NATR / NATV:Waɗannan su ne bearings na allura masu zobe na waje mai lanƙwasa kuma babu zobe na ciki. TR yana nuna zobe na waje mai lanƙwasa da ƙirar wurin da za a iya tura shi, yayin da V ke wakiltar cikakken abin da ke cike da na'urorin naɗa allura (babu keji). Sun dace da ƙananan gudu da kaya masu nauyi.

 

Shawara: Bambancin ko bearing yana da zobe na ciki shine mataki na farko wajen zaɓar bearing. Nau'ikan da ba su da zobe na ciki suna ba da ƙananan farashi da ƙananan girman radial, amma suna buƙatar ƙarin tauri da ingancin saman.

Misali, NA4904-2RS yana nuna wani allura mai girman diamita 20mm ba tare da zobe na ciki ba, wanda aka sanye shi da hatimin roba mai gefe biyu. Ya dace da ƙananan injina ko akwatunan gearbox.

 

3. Yadda Ake Daidaita Samfura da Sauri? Hanyar Zaɓin Matakai Uku

 

Kayyade buƙatun tsarin: Shin ana buƙatar flange don gano wuri? Shin an yarda da shaft ɗin ya zama hanyar tsere?

 

Duba teburin girma: Zaɓi samfurin asali bisa ga sararin shigarwa (diamita na ciki, diamita na waje, da faɗi).

 

Ƙara ƙarin bayani bisa ga yanayin aiki: Yi la'akari da abubuwa kamar rufewa, shafawa, da saurin don zaɓar bambancin da ya dace.

 

Ana ba da shawarar a kwatanta zane-zanen tsarin giciye a cikin littafin jagorar samfurin tare da teburin sigogin girma don fahimtar tsarin ciki da hanyar shigarwa cikin fahimta.
