General sealing pulley:
Cov neeg siv tuaj yeem xaiv qhov sib piv DO / d ntawm lub nominal txoj kab uas hla ntawm steel hlau hlua, DO (D0=D + d) ntawm lub pulley, thiab txoj kab uas hla ntawm lub steel hlau hlua. Tus qauv bearing thiab kev khiav hauj lwm ib puag ncig [yuav tsum tau kev sib khi dav dav lossis nruj sealing (Hom A)] tuaj yeem xaiv raws li lub tshuab rub. (Table 1-4 qhia txog hom kev sib khi dav dav, thiab Table 5-8 qhia txog hom sealing nruj.)
Txoj kev kos npe yog raws li nram no:
Piv txwv li, xaiv ib lub tshuab kaw dav dav nrog al# rim, tus nqi DO / D ntawm 20, thiab tus qauv ntawm 211.
Peb lub Hoobkas tuaj yeem tsim cov khoom tshwj xeeb raws li cov neeg siv khoom xav tau.
Txoj kev xa khoom ntawm txhua yam khoom tsis suav nrog cov kabmob thiab cov npav sab hauv. Thov qhia rau peb ua ntej yog tias cov bearings xav tau rau kev xa khoom.
