Momwe mungasankhire mtundu wa bere

Posankha mtundu wa bearing, ndikofunikira kumvetsetsa bwino momwe bearing idzagwiritsidwire ntchito.

Sankhani njira:

1) Malo oyika bere akhoza kukhala m'malo oyika bere la mtundu wa bere chifukwa kulimba ndi mphamvu ya bere zimasamalidwa popanga dongosolo la bere, kotero kukula kwa bere nthawi zambiri kumatsimikiziridwa kaye, ndiko kuti, m'mimba mwake wamkati wa bere.

Komabe, ma bearing ozungulira amabwera m'mitundu yosiyanasiyana ya kukula ndi mitundu, ndipo mtundu woyenera kwambiri wa bearing uyenera kusankhidwa kuchokera mwa iwo.

 

2) Kukula, komwe kumayang'aniridwa, ndi mtundu wa katundu wonyamula katundu [mphamvu ya katundu wonyamula katunduyo imawonetsedwa ndi katundu woyambira woyesedwa, ndipo mtengo wake uli mu tebulo la kukula kwa katundu wonyamula] Katundu wonyamula katunduyo ndi wosinthasintha, monga kukula kwa katunduyo, kaya pali katundu wozungulira wokha, kaya katundu wa axial ndi wolunjika kapena wolunjika mbali zonse ziwiri, kuchuluka kwa kugwedezeka kapena kugwedezeka, ndi zina zotero. Pambuyo poganizira zinthu izi, ndi nthawi yosankha mtundu woyenera kwambiri wonyamula katunduyo.

 

Kawirikawiri, mphamvu ya radial load ya ma bearing omwe ali ndi bore yomweyo imawonjezeka motere: ma bearing a mpira wozama kwambiri< ma bearing a mpira wolumikizana ndi angular< ma bearing a cylindrical roller< ma bearing a roller opendekeka< ma bearing a roller ozungulira

 

3) Mtundu wa bearing womwe liwiro lake lozungulira limatha kusintha malinga ndi liwiro lozungulira la makina [mtengo wocheperako wa liwiro lozungulira umawonetsedwa ndi liwiro locheperako, ndipo mtengo wake uli mu tebulo la kukula kwa bearing] Liwiro lomaliza la bearing silimangotengedwa kuchokera ku mtundu wa bearing, komanso limangochokera ku kukula kwa bearing, mtundu wa khola, mulingo wolondola, momwe katundu amagwirira ntchito komanso njira zothira mafuta, ndi zina zotero, kotero zinthu izi ziyenera kuganiziridwa posankha.

 

Ma bearing ambiri otsatirawa amagwiritsidwa ntchito pozungulira mofulumira kwambiri:

Ma bereji a mpira wozama, mabearing a mpira wolumikizana ndi angular, mabearing ozungulira ozungulira

 

4) Kulondola kwa kuzungulira: Mtundu wa bearing yokhala ndi kulondola kofunikira kwa kuzungulira. Chosinthira cha zida zamakina, turbine ya gasi ndi makina owongolera zimafuna kulondola kozungulira kwambiri, kuthamanga kwambiri komanso kupsinjika kochepa motsatana, kotero ma bearing okhala ndi kulondola kwa giredi 5 kapena kupitilira apo ayenera kugwiritsidwa ntchito.

 

Ma bearing otsatirawa nthawi zambiri amagwiritsidwa ntchito:

Ma bereji a mpira wozama kwambiri, mabearing a mpira wolumikizana ndi angular,mabearing ozungulira ozungulira

 

5) Mtundu wa bearing womwe kulimba kwake kumakwaniritsa kulimba komwe kumafunikira pakuyika shaft yamakina. Muzigawo monga ma spindles a zida zamakina ndi zida zochepetsera gawo lomaliza la magalimoto, ndikofunikira kukonza kulimba kwa shaft ndi kulimba kwa bearing.

 

Kusintha kwa ma roller bearing ndi kochepa kuposa kwa ma ball bearing.

 

Kugwiritsa ntchito preload (negative clearance) pa bearing kungathandize kulimbitsa. Njirayi ndi yoyenera ma bearing a mpira wolumikizana ndi ma bearing a roller omwe ali ndi ma tapered.

 

6) Unikani kupendekeka pakati pa mphete yamkati ndi mphete yakunja ya bearing (monga kupatuka kwa shaft komwe kumachitika chifukwa cha katundu, kulondola kolakwika kwa shaft ndi chipolopolo kapena cholakwika chokhazikitsa), ndikusankha mtundu wa bearing womwe ungagwirizane ndi momwe ntchito ikuyendera. Ngati kupendekeka kwa mphete yamkati kupita ku mphete yakunja kuli kwakukulu kwambiri, bearing idzawonongeka chifukwa cha katundu wamkati. Chifukwa chake, mtundu wa bearing womwe ungapirire kupendekeka kumeneku uyenera kusankhidwa.

 

Kawirikawiri, ngodya yovomerezeka yokhotakhota (kapena ngodya yozungulira) imawonjezeka motere:

Mabeya ozungulira a cylindrical, mabearing a roller opindika, mabearing a mpira wozama (mabearing a mpira wolumikizana ndi angular), mabearing a roller (mpira) ozungulira

 

7) Ngati nthawi zambiri kusonkhana ndi kusokoneza monga kukhazikitsa ndi kusokoneza nthawi ndi nthawi komanso njira yosonkhanitsira ndi kusokoneza zinthu zimachitika pafupipafupi, ndi bwino kugwiritsa ntchito ma bearing a cylindrical roller, ma bearing a singano ndi ma bearing a tapered roller omwe amatha kulekanitsidwa ndi mphete yamkati ndi mphete yakunja.

 

Ma bearing a mpira wozungulira ndi ma bearing ozungulira okhala ndi bore yocheperako amatha kusonkhanitsidwa mosavuta ndikuchotsedwa pogwiritsa ntchito zomangira kapena manja ochotsera.

 

Ngati mukufuna kudziwa zambiri zokhudza izi, chonde titumizireni uthenga:
