1. Ukucubungula kwangaphambili: Ukukhetha Izinto Eziluhlaza kunye Nonyango Lwangaphambili – Ukulawula Umgangatho Kumthombo
Isiseko somgangatho ekubumbeni ngokuchanekileyo siqala ngokukhethwa kwezinto eziluhlaza okungqongqo kunye nonyango lwangaphambi kwesayensi. Izinto eziphambili ezithwala umthwalo zeeroller chains (iiroller, iibushings, iiplate zeroller, njl.njl.) kufuneka zimelane nemithwalo etshintshanayo, impembelelo, kunye nokuguga. Ke ngoko, ukhetho kunye nonyango lwezinto eziluhlaza luchaphazela ngqo ukusebenza kwemveliso yokugqibela.
1. Ukukhethwa kwezinto eziluhlaza: Ukukhetha intsimbi ehambelana neemfuno zokusebenza
Ngokuxhomekeke kwindlela esetyenziswa ngayo i-roller chain (ezifana noomatshini bokwakha, ii-transmissions zeemoto, kunye nezixhobo zoomatshini abachanekileyo), izinto ezisetyenziswa rhoqo yintsimbi yesakhiwo sekhabhoni esemgangathweni ophezulu okanye intsimbi yesakhiwo se-alloy. Umzekelo, ii-roller kunye nee-bushings zifuna ukumelana nokuguguleka okuphezulu kunye nokuqina, zihlala zisebenzisa iintsimbi ze-alloy carburizing ezifana ne-20CrMnTi. Iipleyiti ze-chain zifuna ibhalansi yamandla kunye nokumelana nokudinwa, zihlala zisebenzisa iintsimbi zesakhiwo sekhabhoni ephakathi ezifana ne-40Mn kunye ne-50Mn. Ngexesha lokukhethwa kwezinto, ukwakheka kweekhemikhali zentsimbi kuvavanywa ngohlalutyo lwe-spectral ukuqinisekisa ukuba umxholo wezinto ezifana nekhabhoni, i-manganese, kunye ne-chromium uhambelana nemigangatho yesizwe efana ne-GB/T 3077, ngaloo ndlela kuthintelwe ukwenza ukuqhekeka okanye ukusilela kokusebenza okubangelwa kukuphambuka kwesakhiwo.
2. Inkqubo yangaphambi konyango: "Ukufudumeza" ukuze kufakwe
Emva kokungena kumzi-mveliso, izinto eziluhlaza zidlula kumanyathelo amathathu aphambili onyango lwangaphambi kokusetyenziswa:
Ukucocwa komphezulu: Ukuqhushumba kweembumbulu kususa isikali, umhlwa, kunye neoyile kumphezulu wentsimbi ukuthintela ukungcola ukuba kungacinezelwa kwindawo yokusebenza ngexesha lokubumba nokubangela iziphene.
