Uyini umehluko phakathi kwamaketanga e-roller e-A Series kanye ne-B Series?

Uyini umehluko phakathi kwamaketanga e-roller e-A Series kanye ne-B Series?

Amaketanga e-roller ayizingxenye ezibalulekile ezinhlelweni zokudlulisa zezimboni zanamuhla futhi asetshenziswa kabanzi emishinini eyahlukahlukene yemishini. Ngokusekelwe ezindinganisweni ezahlukene kanye nezimo zokusetshenziswa,amaketanga okugoqazihlukaniswe kakhulu ngochungechunge lwe-A kanye nochungechunge lwe-B.

I. Izindinganiso kanye Nemvelaphi
Uchungechunge: Luhambisana ne-American Standard for Chains (ANSI), indinganiso eyinhloko emakethe yase-US, futhi lusetshenziswa kabanzi eNyakatho Melika.
Uchungechunge B: Luvumelana ne-European Standard for Chains (ISO), olusekelwe kakhulu e-UK, futhi lusetshenziswa kabanzi eYurophu nakwezinye izifunda.

II. Izici Zesakhiwo
Ubukhulu bepuleti lesixhumanisi sangaphakathi nesangaphandle:
Uchungechunge: Amapuleti okuxhumanisa angaphakathi nangaphandle anobukhulu obulinganayo, afinyelela amandla afanayo angaguquki ngokulungiswa okuhlukile.
Uchungechunge B: Amapuleti okuxhumanisa angaphakathi nangaphandle anobukhulu obulinganayo, afinyelela amandla afanayo angaguquki ngokunyakaza okuhlukahlukene kokujika.
Usayizi Wengxenye kanye Nesilinganiso Sokuphakama:
Uchungechunge: Ubukhulu obuyinhloko bengxenye ngayinye buhambisana nephimbo. Isibonelo, ububanzi bephini = (5/16)P, ububanzi berola = (5/8)P, kanye nobukhulu bepuleti leketanga = (1/8)P (P yiphimbo leketanga).
Uchungechunge B: Ubukhulu bezingxenye eziyinhloko abufani ngokucacile nephimbo.
Umklamo we-Sprocket:
Uchungechunge: Ama-sprocket angenabo abaphathi nhlangothi zombili.
Uchungechunge B: Ama-pulley okushayela ane-boss ohlangothini olulodwa, aqiniswe nge-keyway kanye nemigodi yezikulufo.

III. Ukuqhathaniswa Kokusebenza
Amandla Okudonsa:
Uchungechunge lwe-A: Kumasayizi ayisishiyagalombili e-pitch angu-19.05 kuya ku-76.20 mm, amandla okuthamba makhulu kunalawo e-B Series.
Uchungechunge lwe-B: Kumasayizi amabili e-pitch angu-12.70 mm no-15.875 mm, amandla okuthamba makhulu kunalawo ochungechunge lwe-A.
Ukuphambuka Kobude Beketanga:
Uchungechunge: Ukuphambuka kobude beketanga kungu-+0.13%.
Uchungechunge B: Ukuphambuka kobude beketanga kungu-+0.15%. Indawo Yokusekela Ye-Hinge Pair:
Uchungechunge: Inikeza indawo yokusekela enkulu kunazo zonke yobukhulu bephimbo elingu-15.875 mm kanye no-19.05 mm.
Uchungechunge lwe-B: Lunikeza indawo yokusekela enkulu ngo-20% kune-A Series enobubanzi obufanayo besixhumanisi sangaphakathi.
Ububanzi be-roller:
Uchungechunge: Iphimbo ngalinye linosayizi owodwa werola.
Uchungechunge B: Ububanzi be-roller bukhulu ngo-10%-20% kune-A Series, kanti ububanzi be-roller buyatholakala nge-pitch ngayinye.

IV. Izimo Zokusetshenziswa
Uchungechunge:
Izici: Ifanele izinhlelo zokudlulisa ezinomthwalo ophakathi nendawo kanye nesivinini esiphansi.
Izicelo: Kusetshenziswa kabanzi emishini yokwakha, imishini yezolimo, ekukhiqizeni izimoto, ezinsimbini, emakhemikalini kaphethroli, nakwezinye izimboni.
Uchungechunge lwe-B:
Izici: Ilungele ukunyakaza ngesivinini esikhulu, ukudluliselwa okuqhubekayo, kanye nemithwalo esindayo.
Izicelo: Ngokuyinhloko zisetshenziswa emishinini yezimboni, imishini yensimbi, imishini yendwangu, nezinye izinhlelo zokusebenza.

V. Ukugcinwa Nokunakekelwa
Uchungechunge:
Ukuqina: Ukuqina kokuqina = 1.5%a. Ukudlula u-2% kwandisa ingozi yokugxuma kwamazinyo ngo-80%.
Ukuthambisa: Kufanelekela izindawo ezishisa kakhulu, sebenzisa igrisi ye-graphite.
Uchungechunge lwe-B:
Ukuqina: Ukuqina kokuqina = 1.5%a. Ukudlula u-2% kwandisa ingozi yokugxuma kwamazinyo ngo-80%.
Ukugcoba: Kufanelekela izindawo zokugqwala ezifuthwa ngosawoti, sebenzisa amapuleti eketanga ambozwe nge-Dacromet bese ugcoba njalo ngekota.

VI. Izincomo Zokukhetha
Khetha ngokusekelwe esimweni sesicelo: Uma imishini yakho idinga ukusebenza ngaphansi kwemithwalo ephakathi kanye nesivinini esiphansi, i-A Series ingaba yisinqumo esingcono; uma idinga isivinini esiphezulu, ukudluliselwa okuqhubekayo, kanye nemithwalo esindayo, i-B Series ifaneleka kakhulu.
Cabanga ngezindleko zokulungisa: Kunomehluko othile ekulungiseni phakathi kochungechunge lwe-A ne-B. Uma ukhetha, cabanga ngendawo yokusebenza kwemishini kanye nezinsiza zokulungisa.
Qinisekisa ukuhambisana: Uma ukhetha uchungechunge, qiniseka ukuthi ukuphakama kochungechunge kanye ne-sprocket kuyahambisana ukuze kugwenywe izinkinga zokudlulisela.
