He aha ka manaʻo o A a me B ma ka helu kaulahao?

ʻElua pūʻulu o A a me B ma ka helu kaulahao.ʻO ka moʻo A ʻo ia ka nui kikoʻī e kūlike me ka maʻamau kaulahao ʻAmelika: ʻo ka moʻo B ka nui kikoʻī e kū ana i ka maʻamau kaulahao ʻEulopa (ka nui o UK).Ma waho aʻe o ka pitch like, loaʻa iā lākou ko lākou mau hiʻohiʻona ma nā ʻano ʻē aʻe.ʻO nā ʻokoʻa nui:
1) Ua like ka mānoanoa o ka pā kaulahao i loko a me ka pā kaulahao waho o nā huahana A series, a loaʻa ka hopena ikaika like o ka ikaika static ma o nā hoʻololi like ʻole.Hoʻoponopono ʻia ka pā kaulahao i loko a me ka pā kaulahao waho o nā huahana B series i like, a loaʻa ka hopena ikaika like o ka ikaika static ma o Baidu like ʻole.
2) Loaʻa i nā ana nui o kēlā me kēia ʻāpana o ka moʻo A i kekahi ratio i ka pitch.E like me: pine anawaena = (5/16) P, roller anawaena = (5/8) P, kaulahao pae mānoanoa = (1/8) P (P ke kaulahao pitch), etc. Eia naʻe, ʻaʻohe lākiō maopopo. ma waena o ka nui nui a me ka pitch o nā ʻāpana B series.
3) Ke hoʻohālikelike nei i ka haʻihaʻi haʻahaʻa waiwai o nā kaulahao o ka papa like, koe naʻe ka haʻahaʻa o ka kikoʻī 12B o ka moʻo B ma mua o ka moʻo A, ʻo ke koena o nā kikoʻī e like me nā huahana A series o ka papa like. .

Ua like ke kūlana huahana me ka ISO9606:1994 maʻamau, a ʻo kāna kikoʻī huahana, ka nui a me ka waiwai o ka ukana tensile e kūlike loa me ka pae honua.
Nā hiʻohiʻona hoʻolālā: Ua haku ʻia ke kaulahao me nā pā kaulahao i loko, nā ʻōwili a me nā lima lima, i hoʻopaʻa ʻia me nā loulou kaulahao waho, i haku ʻia me nā papa kaulahao waho a me nā kumu pine.
No ke koho huahana, hiki ke koho ʻia ke kaulahao i koi ʻia e like me ka pihi mana.Inā koho ʻia e like me ka helu ʻana, ʻoi aku ka nui o ka palekana ma mua o 3.
