Njengoba ububanzi obuvumelekile bebanga eliphakathi le-chain drive, kokubili ekubalweni komklamo kanye nokulungisa amaphutha emsebenzini wangempela, buhlinzeka ngezimo ezinhle zokusetshenziswa kwamaketanga anezinombolo ezilinganayo, inani lezixhumanisi ngokuvamile liyinombolo elinganayo. Yinombolo elinganayo yeketanga elenza i-sprocket ibe nenani elingavamile lamazinyo, ukuze iguge ngokulinganayo futhi yandise impilo yayo yesevisi ngangokunokwenzeka.
Ukuze kuthuthukiswe ukushelela kwe-chain drive futhi kuncishiswe umthwalo oguquguqukayo, kungcono ukuba namazinyo amaningi ku-sprocket encane. Kodwa-ke, inani lamazinyo amancane e-sprocket akufanele libe maningi kakhulu, ngaphandle kwalokho =i
kuzoba kukhulu kakhulu, okubangela ukuthi i-chain drive ingasebenzi kahle ngenxa yokweqa kwamazinyo kusenesikhathi.
Ngemva kokuba iketanga selisebenze isikhathi esithile, ukuguguleka kubangela ukuthi amaphini abe mancane futhi imikhono nama-roller abe mancane. Ngaphansi kwesenzo somthwalo oqinile u-F, ukuphakama kweketanga kuyanwebeka.
Ngemva kokuba i-chain pitch ibe yinde, i-pitch circle d iya phezulu kwezinyo lapho i-chain ijikeleza i-sprocket. Ngokuvamile, inani lezixhumanisi ze-chain liyinombolo elinganayo yokugwema ukusebenzisa ama-transition joints. Ukuze kwenziwe ukuguguleka kufane futhi kwandiswe impilo yesevisi, inani lamazinyo e-sprocket kufanele libe yi-prime uma liqhathaniswa nenani lezixhumanisi ze-chain. Uma i-mutual prime ingenakuqinisekiswa, isici esivamile kufanele sibe sincane ngangokunokwenzeka.
Uma iphimbo leketanga likhulu, kulapho umthamo wokuthwala umthwalo ongokwemfundiso uphakama khona. Kodwa-ke, uma iphimbo likhulu, umthwalo oguqukayo uba mkhulu ngenxa yokushintsha kwesivinini seketanga kanye nomthelela wesixhumanisi seketanga esingena ku-sprocket, okuzonciphisa amandla okuthwala umthwalo kanye nokuphila kweketanga. Ngakho-ke, amaketanga amancane kufanele asetshenziswe ngangokunokwenzeka ngesikhathi sokuklama. Umphumela wangempela wokukhetha amaketanga amancane anemigqa eminingi ngaphansi kwemithwalo esindayo uvame ukuba ngcono kunokukhetha amaketanga amakhulu anemigqa eyodwa.
