Kukhazikitsa koyenera kwa zotengera zochepetsera komanso mavuto wamba

Chochepetsera ndi mtundu wa zida zozungulira, ndipo choperekeracho chimagwira ntchito yofunika kwambiri pakuzungulira zida, kotero kukhazikitsa ndi kuyesa choperekeracho ndikofunikira kwambiri pamene choperekeracho chikugwiritsidwa ntchito. Pakugwiritsa ntchito, mavuto ena ofala a mabearing a chochepetsera ndi mavuto okhudzana ndi aliyense, ndipo zotsatirazi zimagawana kukhazikitsidwa kwa mabearing oyenera a choperekeracho ndi mavuto ena ofala.

Kukhazikitsa kwachizolowezi kwa mabearing ochepetsa:

1. Bearing yatsopano iyenera kulinganizidwa kuti igwirizane ndi chitsanzocho, kuyang'ana pamwamba, ndipo muyeso wa radial clearance ukwaniritse zofunikira, ndipo pambuyo poyeretsedwa ndi palafini, iyenera kutenthedwa kufika madigiri 80 ~ 100.°C ndi mafuta a makina, ndipo sungani kutentha kumeneku kwa mphindi 30.

2. Ikani bearing (chitsanzocho chiyenera kuyang'ana kunja) ndikumenya mphete yamkati ndi ndodo yamkuwa, pafupi ndi phewa la shaft, popanda malo otseguka, ndipo sichiyenera kumasulidwa. Bearing ikazizira, bearing iyenera kuzungulira mosinthasintha ndi dzanja, ndipo khola liyenera kugwira ntchito bwino, kuzungulira bwino popanda phokoso logunda. Mukasonkhanitsa, samalani kwambiri momwe gawo lililonse limagwirira ntchito kuti mupewe kusokonekera kapena kuiwala.

3. Mtengo wochepa wa kutentha kwa chogwirira chozungulira: 80°C ya chogwirira chozungulira ndi 65°C ya bearing yotsetsereka. Bearing yozungulira ya mota ndi 100°C. Chifaniziro chosavuta ndi 80°C.

Mavuto ena ofala komanso kulephera kwa ma bearing a reducer

1. N’chifukwa chiyani chimbalangondocho chiyenera kukhala ndi chilolezo chodumphadumpha ndi chilolezo chokulitsa?

Zipangizo zachitsulo zimakhala ndi mphamvu yokulira kutentha komanso kuzizira, ndipo shaft ikagwira ntchito pansi pa kutentha kosiyanasiyana, kutalika ndi m'mimba mwake wa shaft zimasinthanso. Chifukwa chake, kuti zitsimikizire kuti thirakiti yopondereza imapanga filimu yamafuta opondereza, payenera kukhala malo opondereza.

 

Pofuna kuonetsetsa kuti shaft siikulepheretsedwa kapena kuletsedwa panthawi yokulitsa, kupsinjika kwakukulu kumachitika, ndipo bearing imawonongeka, ndipo payenera kukhala mpata wokulitsa.

 

2. Kodi vuto la mafuta oyendera ndi lotani ngati ali otsika kwambiri kapena okwera kwambiri?

Mafuta akachuluka kwambiri, amawonjezera kukana kwa kayendedwe ka mphete ya mafuta ndikutsetsereka kapena kuyima, kukangana kwa mamolekyu amafuta kumawonjezera kutentha kwa chogwirira, kuonjezera kutuluka kwa mafuta pamalo otsetsereka komanso kutayika kwa mphamvu ya kukangana kwa mafuta.

 

Ngati mafuta ali otsika kwambiri, mpira kapena mphete ya mafuta ya bearing sidzatha kunyamula mafuta, zomwe zimapangitsa kuti kutentha kwa bearing kukhale kodzola mafuta ndipo bearing imayaka.

 

Zolakwika zomwe zimachitika kawirikawiri pa zochepetsera ndi ma bearing

1) Bokosi latsopano la mawilo likutentha

2) Bokosi la gearbox lili ndi phokoso

3) Kutuluka kwa mafuta mu gearbox

Ngati muli ndi mafunso okhudza ma bearings a reducer, chonde titumizireni mwachindunji
