Ekubeni uluhlu oluvumelekileyo lomgama ophakathi we-chain drive, kokubini ekubalweni koyilo kunye nokulungisa iimpazamo kumsebenzi wokwenyani, lubonelela ngeemeko ezintle zokusetyenziswa kwee-even-numbered chain, inani lee-links ngokubanzi liyi-even number. Linani evenness le-chain elenza i-sprocket ibe nenani elingaqhelekanga lamazinyo, ukuze inxibe ngokulinganayo kwaye yandise ubomi bayo benkonzo kangangoko kunokwenzeka.
Ukuze kuphuculwe ukugudiseka kwe-chain drive kwaye kuncitshiswe umthwalo oguqukayo, kungcono ukuba namazinyo amaninzi kwi-sprocket encinci. Nangona kunjalo, inani lamazinyo amancinci e-sprocket akufuneki libe maninzi kakhulu, kungenjalo =i
iya kuba nkulu kakhulu, nto leyo ebangela ukuba i-chain drive ingasebenzi ngenxa yokutsiba kwamazinyo kwangethuba.
Emva kokuba itsheyini sele isebenza ixesha elithile, ukuguguleka kubangela ukuba iiphini zibe ncinci kwaye imikhono kunye neerola zibe ncinci. Phantsi kwesenzo somthwalo otyhalwayo u-F, iphimbo letsheyini liyanwebeka.
Emva kokuba i-chain pitch ibe nde, i-pitch circle d iya ngasentla kwezinyo xa i-chain ijikeleza i-sprocket. Ngokubanzi, inani lee-chain links lilingana nenani lokuthintela ukusetyenziswa kwamalungu otshintsho. Ukuze kwenziwe ukuguguleka kufane kwaye kwandiswe ubomi benkonzo, inani lamazinyo e-sprocket kufuneka libe li-prime xa inani lee-chain links liqiniswe. Ukuba i-mutual prime ayinakuqinisekiswa, into eqhelekileyo kufuneka ibe ncinci kangangoko.
Okukhona iphimbo letsheyini lilikhulu, kokukhona umthamo wokuthwala umthwalo wethiyori uphezulu. Nangona kunjalo, iphimbo lilikhulu, kokukhona umthwalo oguqukayo ukhula ngenxa yotshintsho lwesantya setsheyini kunye nempembelelo yekhonkco letsheyini elidibanisa i-sprocket, nto leyo eya kunciphisa amandla okuthwala umthwalo kunye nobomi betsheyini. Ke ngoko, iitsheyini ezincinci kufuneka zisetyenziswe kangangoko kunokwenzeka ngexesha loyilo. Isiphumo sokwenyani sokukhetha iitsheyini ezincinci ezinemigca emininzi phantsi kwemithwalo enzima sidla ngokuba ngcono kunokukhetha iitsheyini ezinkulu ezinemigca enye.
