Pehea e hoʻoholo ʻia ai ka ratio hoʻoili o ka sprocket?

I ka helu ʻana i ke anawaena o ka sprocket nui, pono ke helu ʻana i nā helu ʻelua i ka manawa like:
1. E helu ma muli o ka ratio ho'ouna: 'o ka ma'amau ka palena o ka ho'ouna 'ana i ka li'ili'i ma mua o 6, a 'o ka ratio ho'ouna 'oi loa ma waena o 2 a me 3.5.
2. E koho i ka lākiō hoʻoili e like me ka helu o nā niho o ka pinion: i ka manawa o ka helu o nā niho pinion ma kahi o 17 niho, pono e emi ka ratio hoʻouna ma mua o 6; i ka manawa o ka helu o nā niho pinion he 21 ~ 17 niho, ka lākiō hoʻoili he 5 ~ 6; i ka nui o na niho pinion he 23~ I ka manawa he 25 niho o ka pinion, he 3~4 ka ratio hooili; i ka wā o nā niho pinion he 27 ~ 31 niho, ʻo ka lākiō hoʻoili he 1 ~ 2. Inā ʻae nā ʻāpana o waho, e hoʻāʻo e hoʻohana i kahi sprocket liʻiliʻi me ka nui o nā niho, maikaʻi ia no ka paʻa o ka lawe ʻana a hoʻonui i ke ola o ke kaulahao.

ʻO nā palena kumu o ka sprocket: ka pitch p o ke kaulahao pili, ka palena kiʻekiʻe o waho o ka roller d1, ka lālani pitch pt a me ka helu o nā niho Z. Hōʻike ʻia nā ana nui a me nā helu helu o ka sprocket ma ka papa ma lalo. . 'Oi aku ka li'ili'i o ke anawaena o ka puka sprocket hub ma mua o kona anawaena i 'ae 'ia. ʻAʻole i kuhikuhi ʻia nā ʻano niho sprocket i nā kūlana ʻāina no nā sprocket, ʻo ka nui a me ka liʻiliʻi o nā niho niho a me nā palena palena. ʻO kekahi o nā ʻano niho maʻamau i hoʻohana ʻia i kēia manawa, ʻo ia ka pōʻai ʻekolu.
Aloha ʻoe, nā ʻāpana kumu o ka sprocket: ka pitch p o ke kaulahao pili, ke anawaena o waho loa o ka roller d1, ka lālani pitch pt a me ka helu o nā niho Z. Hōʻike ʻia nā ana nui a me nā kumu helu o ka sprocket ma ka papa ma lalo. 'Oi aku ka li'ili'i o ke anawaena o ka puka sprocket hub ma mua o kona anawaena dkmax. ʻAʻole i kuhikuhi ʻia nā ʻano niho sprocket i nā kūlana ʻāina no nā sprocket, ʻo ka nui a me ka liʻiliʻi o nā niho niho a me nā palena palena. ʻO kekahi o nā ʻano niho maʻamau i hoʻohana ʻia i kēia manawa, ʻo ia ke ʻano niho ʻekolu arc a me ka laina pololei.
