Ama-pulleys anesisindo ama-cranes (abizwa nangokuthi ama-pulleys anesisindo noma ama-pulleys aphezulu) ama-pulleys aphezulu) yi-pulley asgain eyenzelwe imithwalo esindayo, imvamisa ephezulu, kanye nezimo zokusebenza ezinokhahlo. Zivame ukusetshenziswa ekuphakamiseni imishini emikhakheni yeMetallurgy, amachweba, izimayini kanye nemishini yobunjiniyela obukhulu. Izici zayo zokusebenza zikhonjiswa ikakhulu emandleni aphezulu, ukumelana nokugqoka okuphezulu, kanye nokwethenjwa okuphezulu ukuze kuhlangatshezwane nezidingo zezinhlelo zokusebenza ezisindayo (njenge-M6M8).
Umthamo ophezulu wokulayisha umthwalo
Amandla aphezulu abonakalayo: Insimbi ye-Alloy (enjenge-42CRMO, 35CRMO) noma i-iron ekhethekile yokushisa iyasetshenziswa ukuthuthukisa amandla okugoqa ngentambo yocingo futhi yehlisa i-wire foole Isici sezikhathi ezingama-≥5 zisetshenziswa ekwakhiweni ukuze kuqinisekiswe ukuphepha ngaphansi kwemithwalo eyeqisayo.
Gqoka ukumelana nempilo ende
I-Pullley Groove Harding Treatment: Imvamisa ephezulu yokuqedwa, ukucwazimula okucwazimulayo noma i-chromium arving engamelana ne-chromium) kusetshenziselwa ukuthuthukisa i-pure groove hardness.

aimpact ukumelana: I-coating: ezindaweni ezihlanzekayo (njengamachweba namakhemikhali), i-galvanized, insimbi engenacala noma i-nylon coating isetshenziselwa ukwenza ngcono ukumelana nokugqwala.
Ukungqubuzana okuphansi nokusebenza kahle
Izingcingo ezisezingeni eliphakeme: Ukugibela okugoqayo (okufana nama-roller beresings) asetshenziswayo, ngokusebenza kahle okuphezulu nokusebenza kwamafutha okuzenzakalelayo (okufana namafutha okufutheka) ukunciphisa i-supto ezenzakalelayo (i-pulley grooce: Polishing ukunciphisa ukungqubuzana okushelelayo kwentambo yocingo.
Ukusebenza kahle kwesakhiwo
Isakhiwo esiphindwe kabili Izintambo zocingo ezinhlangothini zombili zilinganise futhi zigweme ukulayisha i-eccentric.
Ukulungiswa nokuhlolwa
Ukuhlolwa okujwayelekile: Ukuqapha i-pulley groove kugqoke (ukujula ≤10% ububanzi bezintambo), ukuthwala imvume, ukufundwa kwe-pulley (njll .
