Uma ufuna i-roller chain yemishini yakho yezimboni, kungenzeka ukuthi uhlangane namagama athi “40 roller chain” kanye “41 roller chain.” Lezi zinhlobo ezimbili ze-roller chain zivame ukusetshenziswa ezinhlelweni ezahlukene, kodwa yini ngempela ezihlukanisayo? Kule bhulogi, sizohlola umehluko phakathi kwe-40 kanye ne-41 roller chain ukuze sikusize wenze isinqumo esinolwazi ngezidingo zakho ezithile.
Okokuqala nokubaluleke kakhulu, kubalulekile ukuqonda ukuthi zombili izintambo ze-roller ezingu-40 no-41 ziyingxenye yochungechunge lwezintambo ze-roller ezijwayelekile ze-ANSI (American National Standards Institute). Lokhu kusho ukuthi zenzelwe ubukhulu obuthile kanye nezindinganiso zekhwalithi, okwenza zikwazi ukushintshaniswa nezinye izintambo ze-roller ezijwayelekile ze-ANSI. Kodwa-ke, naphezu kokufana kwazo, kunezimo eziyinhloko ezihlukanisa izintambo ze-roller ezingu-40 no-41.
Omunye wemehluko omkhulu phakathi kwe-roller chain engu-40 no-41 usekujuleni kwayo. I-pitch ye-roller chain ibhekisela ebangeni eliphakathi kwezindawo eziseduze, futhi idlala indima ebalulekile ekunqumeni amandla e-chain kanye nomthamo wokuthwala umthwalo. Endabeni ye-roller chain engu-40, i-pitch ilinganiselwa kuma-intshi angu-0.5, kuyilapho i-pitch ye-roller chain engu-41 incane kancane kuma-intshi angu-0.3125. Lokhu kusho ukuthi i-roller chain engu-40 ifaneleka kangcono kwizinhlelo zokusebenza ezidinga amandla aphezulu nokuqina, kuyilapho i-roller chain engu-41 ingase ifaneleke kakhulu ekusetshenzisweni okulula.
Ngaphezu kwephimbo, esinye isici esibalulekile okufanele usicabangele lapho uqhathanisa uchungechunge lwama-roller angu-40 no-41 amandla alo okudonsa. Amandla okudonsa abhekisela enanini eliphezulu lokucindezeleka kokudonsa into engamelana nakho ngaphandle kokuphuka, futhi kuyinto ebalulekile ekunqumeni ukufaneleka kochungechunge lwama-roller kwisicelo esithile. Ngokuvamile, uchungechunge lwama-roller angu-40 luvame ukuba namandla okudonsa aphezulu uma kuqhathaniswa nochungechunge lwama-roller angu-41, okwenza kube ukukhetha okuthandwayo kwezicelo ezisindayo lapho uchungechunge luzobhekana nemithwalo namandla amakhulu.
Ngaphezu kwalokho, ubukhulu bezingxenye ngazinye ze-roller chain engu-40 kanye nengu-41 buhluka kancane. Isibonelo, ububanzi bama-roller ku-roller chain engu-40 buvame ukuba bukhulu kunobe-roller chain engu-41, okuvumela ukuthintana okungcono nokuzibandakanya nama-sprocket. Lo mehluko ngobukhulu be-roller ungathinta ukusebenza kahle kanye nokusebenza kahle kwe-roller kuzo zonke izinhlelo zokusebenza.
Okunye okubalulekile okufanele ukucabangele lapho ukhetha phakathi kwe-40 ne-41 roller chain ukutholakala kwama-sprocket nezinye izesekeli. Njengoba i-40 roller chain isetshenziswa kakhulu ezindaweni zezimboni, kungaba lula ukuthola uhla olubanzi lwama-sprocket nezesekeli ezihambisanayo ze-40 roller chain uma kuqhathaniswa ne-41 roller chain. Lokhu kungaba yisici esibalulekile kwezinye izinhlelo zokusebenza lapho kudingeka khona osayizi noma ukucushwa kwe-sprocket ethile.
Ekugcineni, ukukhetha phakathi kwe-roller chain engu-40 no-41 kuzoncika ezidingweni ezithile zesicelo sakho. Uma udinga i-roller chain engaphatha imithwalo esindayo futhi inikeze ukusebenza okuthembekile ezimweni ezinzima, i-roller chain engu-40 ingaba inketho engcono. Ngakolunye uhlangothi, uma isicelo sakho sihilela imithwalo elula futhi sidinga ukwakheka kwe-chain encane, i-roller chain engu-41 ingaba efaneleka kakhulu.
Ekuphetheni, yize uchungechunge lwe-roller lwe-40 kanye ne-41 luyingxenye yochungechunge olujwayelekile lwe-ANSI, luhlukile ngokwe-pitch, amandla okudonsa, ubukhulu bezingxenye, kanye nokufaneleka kohlelo lokusebenza. Ukuqonda lokhu kungafani kubalulekile ekukhetheni uchungechunge lwe-roller olufanele lwemishini yakho nemishini. Ngokubheka izidingo ezithile zesicelo sakho kanye nokucabangela izici ezihlukile zohlobo ngalunye lwe-roller chain, ungenza isinqumo esinolwazi esiqinisekisa ukusebenza kahle kanye nokuthembeka. Kungakhathaliseki ukuthi ukhetha uchungechunge lwe-roller lwe-40 noma lwe-41, ungathemba ukuthi zombili izinketho zenzelwe ukuhlangabezana nezindinganiso zekhwalithi ephezulu kanye nokusebenza kwezidingo zakho zezimboni.
