Nau'in bearings masu sauƙi

 

Gibin da ke tsakanin shaft dahaliyana hulɗa da saman, wanda ake kira bearing mai sauƙi. Ana amfani da shi sosai saboda yana da alaƙa da saman da zai iya jure manyan ƙarfin waje, yana da juriya ga girgiza, kuma yana da tsari mai sauƙi. Misali, haɗin da ke motsawa na Hannun Dodanni na Excavator.

 

Zamiya bearingsza a iya raba shi zuwa nau'i uku bisa ga jagorancin ƙarfi, wato:

 

1. Ɗaukar hoto mai zamiya

Alkiblar ƙarfin bearings na radial plain bearings yana tsaye ne a tsakiyar axis, wanda za'a iya raba shi zuwa nau'i uku bisa ga siffar:

 

1) Bearing na Integral: Bearing na Integral wani bearing ne na gama gari wanda aka haɗa shi da firam ɗin tare da ƙusoshi. Matsin ciki na wurin zama na bearing, an sanya kofin mai a saman gidan bearing ɗin, ramin shigar mai yana kan hannun shaft ɗin, kuma saman ciki yana cike da bearing (ko hannun shaft) da aka yi da kayan hana gogayya don buɗe ramin mai na axial don rarraba man shafawa mai mai.

 

2) Haɗaɗɗen bearing: Wannan nau'in bearing yana da matuƙar dacewa don shigarwa da wargaza shi, kuma farashin yana da ƙasa, kuma ana amfani da shi sosai a fannin injiniya. Misali, bearings akan cranks na nau'ikan injunan konewa na ciki daban-daban

 

3) Bearing mai sassa huɗu: wanda kuma aka sani da bearing mai sassa huɗu, wanda ake amfani da shi a manyan motoci, kamar injunan girgiza, injunan girgiza da sauran bearing na spindle.

 

Kayan da ake amfani da su wajen yin bearings galibi ƙarfe ne da ƙarfen siminti. Saboda taurin da yake da shi, yana da sauƙin lalacewa, don haka yawanci ana ƙara bushing tsakanin shaft da bearing. Kayan da ake amfani da su wajen yin wannan bushing galibi sune tagulla, farin gami da barbit gami.

 

2. Zamiya tura bearings

 

Nauyin bearing ɗin da aka tura yana daidai da alkiblar axial, wanda ba wai kawai yana tallafawa juyawar injin ba, har ma yana hana motsi a kan axis. Ana iya raba shi zuwa nau'i huɗu:

 

1) Ƙarfin matse zobe: an raba shi zuwa:

 

(1) Bearing na tura zobe ɗaya: Bearing na tura zobe ɗaya, wanda zai iya jure matsin lamba a kowane bangare.

 

(2) Bearing mai zobe da yawa: Wannan nau'in shaft zai iya ɗaukar bugun axial a duka hanyoyi, babban gudu da nauyi mai nauyi.

 

2) Bearing na aji: wanda kuma aka sani da pivot bearing, bearing ne mai zamiya wanda aka sanya a ƙarshen shaft, don haka ana kiransa bearing na put column tushe.

 

3) Bearing na ture na man shafawa mai ƙarfi: an yi saman gogayya tsakanin shaft da bearing zuwa saman da aka karkata ko kuma tubalin da za a iya karkata. Ana samar da wani Layer na man hydrodynamic a kan kowane saman da aka karkata ko tubalin da aka karkata ta yadda shaft ɗin ba zai taɓa bearing ba.

 

4) Bearing na Hydrostatic: Idan nauyin naúrar bearing ya yi yawa, ba zai yiwu a kafa fim ɗin mai ta hanyar farawa mai tsauri ba, don haka dole ne a yi amfani da bearing na hydrostatic. Ana matsa ruwan (man) ta famfo kuma a aika shi tsakanin sassan biyu don kula da man shafawa yayin aiki. Saboda duniyar waje ce ke samar da ruwan, ana kuma kiransa bearing na waje. Idan aka canza matsin man famfo zuwa matsin iska, ana kiransa bearing na hydrostatic air.

 

3. Bearings na musamman masu zamiya

 

1) Bearing mai ramuka: wanda kuma aka sani da bearing mai cike da mai, ana fasa shi ta hanyar hanyar fasa ƙarfe ta foda. Gabaɗaya ya dace da bearing masu sauƙin nauyi.

 

2)Bearings marasa mai: suna da juriya mai kyau, sun dace da kayan aiki masu sauƙi da kuma waɗanda ba sa gurɓata abinci, kamar bearings na Nelong.
