Daban-daban mirgina bearings da daban-daban halaye kuma sun dace da daban-daban aikace-aikace yanayi na daban-daban inji kayan aiki. Ya kamata ma'aikatan zaɓi su zaɓi ƙirar ƙirar da ta dace daga masana'anta daban-daban da nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan.

1. Zaɓi samfurin ɗaukar hoto bisa ga yanki da matsayi na kayan aikin injin ɗin da aka mamaye:

Kullum muna amfani da ballbearingsdon ƙananan ramuka, da abin nadi don manyan ramuka. Idan an iyakance diamita na abin ɗamarar, gabaɗaya muna amfani da abin nadi na allura, bearings ball bearings ko nadi bearings; lokacin da aka ƙayyade a cikin ɓangaren axial na kayan aiki, kunkuntar ko matsananci kunkuntar jerin ƙwallon ƙwallon ƙafa ko abin nadi.

2. Zaɓi samfurin ɗaukar hoto bisa ga kaya. Ya kamata nauyin ya zama abu mafi mahimmanci da za a yi la'akari yayin zabar bearings:

Nadi bearings iya jure in mun gwada da manyan lodi, yayin da ball bearings ne in mun gwada da kananan. Bearings da aka yi da carburized karfe iya jure girgiza da kuma girgiza lodi. Lokacin da ake buƙatar nauyin radial kawai, za mu iya zaɓar ƙwanƙwasa ƙwallon ƙafa, nadi na silindi ko nadi na allura. Lokacin da nauyin axial yana da ƙananan ƙananan, za mu iya zaɓar ƙwallon ƙwallon ƙafa; lokacin da nauyin axial ya yi girma sosai, ana amfani da abin nadi na turawa gabaɗaya. Lokacin da mai ɗaukar kaya ya ɗauki nauyin axial da radial, gabaɗaya muna amfani da ƙwallon ƙwallon ƙafa na kusurwa ko naɗar abin nadi.

3. Dangane da halaye masu daidaita kai na ɗaukar hoto, zaɓi samfurin ɗaukar hoto:

Lokacin da axis na shaft ɗin ba daidai yake da axis na wurin zama ba, ko kuma yana da sauƙi a lanƙwasa ko karkatar da shi a ƙarƙashin matsin lamba, ƙwallon da ke daidaita kansa ko naɗaɗɗen abin nadi mai kyau tare da kyakkyawan aikin daidaitawa, da kuma ta. Za'a iya zaɓar ɗaukar ƙwallon waje. Irin wannan nau'i na iya tabbatar da aiki na al'ada lokacin da aka danƙa maɗaukaki ko lankwasa. Ribobi da rashin lahani na aikin daidaitawa mai ɗaukar nauyi suna da alaƙa da yuwuwar rashin axiality ɗin sa. Mafi girman ƙimar, mafi kyawun aikin daidaita kai.

4. bisa ga taurin kai, zaɓi samfurin ɗaukar hoto:

Nakasar roba na mirginabearingsba babba ba ne kuma ana iya yin watsi da shi a yawancin kayan aikin injiniya, amma a cikin wasu kayan aikin injiniya, irin su mashinan kayan aikin na'ura, ɗaukar taurin abu ne mai mahimmanci.
Gabaɗaya muna amfani da silinda na abin nadi ko abin nadi da aka ɗora don kayan aikin sandar sandar ƙarfe. Domin waɗannan nau'ikan haɓakar guda biyu suna nuna lamba ce lokacin da ake amfani da shi, tsayayyen yana da rauni.
Bugu da kari, daban-daban bearings kuma za su iya amfani da preloading don ƙara taurin kai. Irin su ƙwallon ƙwallon ƙafa na angular da ƙwanƙwasa ƙwanƙwasa, don inganta ƙarfin goyan baya, ana ƙara wani ƙarfin axial a gaba yayin haɗuwa don sa su manne juna. An jaddada shi musamman a nan: ƙarfin da aka yi amfani da shi ba zai iya zama babba ba. In ba haka ba, juzu'i na ɗaukar nauyi na iya ƙaruwa, haɓakar zafin jiki zai ƙaru, kuma rayuwar sabis na ɗaukar nauyi zai kasance cikin haɗari.

5. bisa ga saurin ɗaukar nauyi, zaɓi ƙirar ƙira:

Gabaɗaya magana, bearings angular lamba bearings da cylindrical roller bearings sun dace don amfani a wuraren aiki masu sauri; Za a iya amfani da ɗigon abin nadi a cikin ƙananan wuraren aiki. Ƙwararrun ƙwallon ƙwallon ƙafa suna da ƙananan ƙayyadaddun saurin iyaka kuma sun dace kawai ga wurare masu ƙananan gudu.

Don nau'in ɗaukar nauyi iri ɗaya, ƙarami ƙayyadaddun ƙayyadaddun bayanai, mafi girman saurin jujjuyawar da aka yarda. Lokacin zabar ƙirar ƙira, kula da ainihin gudun ƙasa da iyakar iyaka.
