Yintoni umahluko phakathi kwee-roller chains ze-A Series kunye ne-B Series?

Iintambo zeroli zizinto ezibalulekileyo kwiinkqubo zothumelo lwemizi-mveliso zanamhlanje kwaye zisetyenziswa kakhulu kwizixhobo ezahlukeneyo zoomatshini. Ngokusekelwe kwimigangatho eyahlukeneyo kunye neemeko zokusetyenziswa,imixokelelwane yerollerzahlulwe ngokubanzi zibe yi-A Series kunye ne-B Series.

I. Imigangatho kunye neMvelaphi
Uthotho: Ihambelana ne-American Standard for Chains (ANSI), umgangatho ophambili kwimarike yaseMelika, kwaye isetyenziswa kakhulu eMntla Melika.
Uthotho lwe-B: Luhambelana ne-European Standard for Chains (ISO), olusekwe kakhulu e-UK, kwaye lusetyenziswa kakhulu eYurophu nakwezinye iindawo.

II. Iimpawu zesakhiwo
Ubukhulu bepleyiti yekhonkco yangaphakathi neyangaphandle:
Uthotho: Iipleyiti zokudibanisa zangaphakathi nezangaphandle zilingana ngobukhulu, zifikelela kumandla angaguqukiyo afanayo ngokulungiswa okuhlukeneyo.
Uthotho lwe-B: Iipleyiti zokudibanisa zangaphakathi nezangaphandle zilingana ngobukhulu, zifikelela kumandla angaguqukiyo afanayo ngeentshukumo ezahlukeneyo zokujika.
Ubungakanani beCandelo kunye nomlinganiselo wePitch:
Uthotho lwe-A: Ubukhulu obuphambili becandelo ngalinye buhambelana nepitch. Umzekelo, ububanzi bepin = (5/16)P, ububanzi beroller = (5/8)P, kunye nobukhulu beplate yeketanga = (1/8)P (P yipitch yeketanga).
Uthotho lwe-B: Ubukhulu becandelo eliphambili abuhambelani ngokucacileyo nephimbo.
Uyilo lweSprocket:
Uthotho: Ii-Sprockets ezingenabo abaphathi kumacala omabini.
Uthotho B: Iipulleys zokuqhuba ezinebhosi kwicala elinye, ziqiniswe ngesitshixo sendlela kunye nemingxuma yezikrufu.

III. Uthelekiso loMsebenzi
Tensile strength:
Uthotho lwe-A: Kwiipitshi ezisibhozo ezibukhulu obuyi-19.05 ukuya kwi-76.20 mm, amandla okutsalwa aphezulu kunalawo othotho lwe-B.
Uthotho lwe-B: Kwiisayizi ezimbini zepitch eziyi-12.70 mm kunye ne-15.875 mm, amandla okutsalwa makhulu kunalawo othotho lwe-A.
Ukuphambuka kobude beTyeya:
Uthotho: Ukuphambuka kobude betsheyini yi +0.13%.
Uthotho lwe-B: Ukuphambuka kobude betsheyini yi-+0.15%. Indawo yenkxaso yeHinge Pair:
Uthotho: Ibonelela ngeyona ndawo inkulu yokuxhasa ubukhulu bepitshi eyi-15.875 mm kunye ne-19.05 mm.
Uthotho lwe-B: Inika indawo yokuxhasa enkulu ngama-20% kune-A Series enobubanzi obufanayo bekhonkco langaphakathi.
Ububanzi beRoller:
Uthotho: Iphimbo ngalinye linobukhulu obufanayo berola.
Uthotho lwe-B: Ububanzi berola bukhulu nge-10%-20% kune-A Series, kwaye ububanzi berola bufumaneka kwipitch nganye.

IV. Imizekelo yokusetyenziswa
Uthotho:
Iimpawu: Ifanelekile kwiinkqubo zothumelo ezinomthwalo ophakathi kunye nezikhawulezayo.
Izicelo: Isetyenziswa kakhulu koomatshini bokwakha, oomatshini bezolimo, ukwenziwa kweemoto, isinyithi, iikhemikhali zepetrochemicals, kunye namanye amashishini.
Uthotho lwe-B:
Iimpawu: Ifanelekile kwisantya esiphezulu, ukudluliselwa okuqhubekayo, kunye nemithwalo enzima.
Izicelo: Ngokuyintloko zisetyenziswa kwimishini yemizi-mveliso, kwimishini yesinyithi, kwimishini yelaphu, nakwezinye iinkqubo.

V. Ukugcinwa Nokukhathalela
Uthotho:
Uxinzelelo: Uxinzelelo luyancipha = 1.5%a. Ukudlula i-2% kwandisa umngcipheko wokutsiba kwamazinyo nge-80%.
Ukuthambisa: Ifanelekile kwiindawo ezinobushushu obuphezulu, sebenzisa igrisi yegrafiti.
Uthotho lwe-B:
Uxinzelelo: Uxinzelelo luyancipha = 1.5%a. Ukudlula i-2% kwandisa umngcipheko wokutsiba kwamazinyo nge-80%.
Ukuthambisa: Ifanelekile kwiindawo zokugqwala kwetyuwa, sebenzisa iipleyiti zetyathanga ezigqunywe yiDacromet kwaye uthambise rhoqo ngekota.

VI. Iingcebiso zoKhetho
Khetha ngokusekelwe kwimeko yesicelo: Ukuba izixhobo zakho zifuna ukusebenza phantsi kwemithwalo ephakathi kunye nesantya esiphantsi, i-A Series inokuba lukhetho olungcono; ukuba ifuna isantya esiphezulu, ukudluliselwa okuqhubekayo, kunye nemithwalo enzima, i-B Series ifanelekile ngakumbi.
Cinga ngeendleko zokulungisa: Kukho umahluko othile ekugcinweni kwezixhobo phakathi koluhlu lwe-A kunye nolwe-B. Xa ukhetha, cinga ngendawo yokusebenza kwezixhobo kunye nezixhobo zokulungisa.
Qinisekisa ukuba iyahambelana: Xa ukhetha itsheyini, qiniseka ukuba iphimbo letsheyini kunye nesprocket ziyafana ukuze kuthintelwe iingxaki zokudluliselwa kwegesi.
