Me ka hala ʻana o ka manawa, ua lilo nā kia i ʻāpana koʻikoʻi o nā mīkini. I ke ola o kēlā me kēia lā, hiki ke ʻike ʻia ka hoʻohana ʻana o nā kia ma nā wahi āpau, mai nā mokokaikala a i nā mokulele a me nā moku.
Pēlā nō, hoʻohana pinepine ʻia nā kia i nā kaʻa a ua hala i hoʻokahi haneli mau makahiki o ka mōʻaukala, ʻoiai nā kia o nā kaʻa, e pono ai nā kia e hoʻololi i nā kia. Eia nō naʻe, ua ʻike nā mea nona nā kaʻa akahele i ke kumu ʻaʻole he spur nā kia o nā kia o nā kia kaʻa, akā ʻo ka hapa nui o lākou he helical?
ʻO kaʻoiaʻiʻo, ʻelua ʻano o nā kia o nā pahu pahu:nā kia helicala menā kia hoʻoulu.
I kēia manawa, hoʻohana ka hapa nui o nā pahu pahu ma ka mākeke i nā kia helical. He maʻalahi ka hana ʻana o nā kia spur, hiki ke hoʻokō pololei i ka meshing me ka ʻole o ka synchronizer, a hiki i ke kau ʻana o ka hopena shaft ke hoʻohana pololei i nā bearings ball groove hohonu, me ka ʻole o ka ikaika axial. Eia nō naʻe, e loaʻa nā hewa i ke kaʻina hana o nā kia spur, kahi e hana ai i ka wikiwiki like ʻole, ʻaʻole kūpono no nā mīkini wikiwiki a me nā torque kiʻekiʻe.
Ke hoʻohālikelike ʻia me nā kia spur, he ʻano niho slanted ko nā kia helical, e like me ka wili ʻana i ka wili, e wili iki ana, aia kahi manaʻo ikaika o ka omo. ʻO ka ikaika like o nā niho pololei e like me ka meshing. No laila, i ka wā e noho ai ke kia i loko o ka kia, ʻoi aku ka maikaʻi o nā niho helical ma mua o nā niho pololei. Eia kekahi, ʻo ka ikaika i lawe ʻia e nā niho helical e paheʻe mai kekahi ʻaoʻao a i kekahi ʻaoʻao, no laila ʻaʻohe kuʻi ʻana o nā niho i ka wā e hoʻololi ai i nā kia, a ʻoi aku ka lōʻihi o ke ola lawelawe.
He holomua ka mīkini helical, a he kiʻekiʻe ke kiʻekiʻe o ka overlap o nā niho, no laila he paʻa loa ia a he haʻahaʻa ka walaʻau i ka wā o ka hoʻoili ʻana, a ʻoi aku ka kūpono no ka hoʻohana ʻana ma lalo o nā kūlana hoʻokele wikiwiki a me nā ukana kaumaha.
