He aha ka Circular Pitch i nā Gears?

Ma ka ʻenekinia kia,kahua pōʻaiʻo ia kekahi o nā ana kumu loa i hoʻohana ʻia e wehewehe i ka mamao o nā niho a puni kahi kia. Hoʻopilikia pololei ia i ke ʻano o ka launa pū ʻana o nā kia, ka hoʻouna ʻana i ka neʻe, a me ka mālama ʻana i ka synchronization i nā ʻōnaehana hoʻoili mana. He mea nui ka hoʻomaopopo ʻana i ka pitch pōʻai no ka hoʻolālā kia pololei a me ka hoʻohālikelike ma waena o nā kia pili.

Ka Wehewehena o ke Kikowaena Pōʻai

Ua wehewehe ʻia ka pitch pōʻai (p) ʻo ia ka mamao ma waena o kahi kiko ma kekahi niho kia a me ke kiko like ma ka niho aʻe, i ana ʻia ma ka pōʻai pitch.
ʻO kapōʻai pitchhe pōʻai kuhikuhi hoʻokalakupua ia e hōʻike ana i ke kiko o ka hoʻopili ʻana ma waena o ʻelua mau kia pili.

I mea e hoʻopili pono ai nā kia ʻelua, pono e like ko lāua mau pitch poepoe e hōʻoia ana e kūpono pono kēlā me kēia niho ma kekahi kia i ka hakahaka ma waena o nā niho ma kekahi.

Haʻilula a me ka Heluhelu ʻana

Ua loaʻa ke ʻano hana no ka helu ʻana i ka pitch pōʻai mai ke anapuni o ka pōʻai pitch a me ka helu o nā niho: p=πd​/N

Ma hea:

•  p = Kiʻekiʻe pōʻai

• d = Ke anawaena pitch (ke anawaena o ka pōʻai pitch)

• N = Helu o nā niho

Hōʻike kēia haʻilula e pili ana ka pitch poepoe i ka nui o ke kia a me ka nui o nā niho i loaʻa - ʻo nā kia nui aʻe a i ʻole nā ​​​​niho liʻiliʻi e hopena i ka mamao pitch nui aʻe.

Pilina ma waena o ke Kikowaena Pōʻai a me ke Kikowaena Diametra

Ua pili loa ke kiʻekiʻe pōʻai i kekahi ana kia maʻamau i ʻike ʻia ʻo ka diametral pitch (P), kahi i hoʻohana nui ʻia i ka ʻōnaehana imperial.

Hōʻike ka pitch diametral i ka helu o nā niho no kēlā me kēia ʻīniha o ke anawaena pitch, a ua hoʻopili ʻia nā mea ʻelua ma ke ʻano makemakika penei: p=π​/p

ʻAe kēia pilina i nā ʻenekinia e hoʻololi maʻalahi ma waena o nā ʻōnaehana kia metric-based (circular pitch) a me nā ʻōnaehana kia imperial-based (diametral pitch).

I ka manawa hea e hoʻohana ai i ka Circular Pitch

ʻOiai ʻo ka diametral pitch ka mea maʻamau i nā noi kia maʻamau he nui, hāʻawi ka circular pitch i nā pono i nā hihia kikoʻī:

1. Nā ʻōnaehana neʻe laina (Rack a me Pinion):
He kūpono ke kiʻekiʻe pōʻai no nā ʻōnaehana rack a me pinion, kahi e hoʻololi ʻia ai ka neʻe ʻana o ka wili i ka neʻe linear. ʻO ka hoʻohana ʻana i ka pitch pōʻai e hoʻomaʻalahi i ka indexing a me ke kūlana, ʻoiai ʻo kēlā me kēia wili e pili ana i kahi mamao linear paʻa.
2. Nā Kia Anawaena Nui:
No nā kia nui, hāʻawi ka pitch pōʻai i kahi ana pololei o ka mamao o nā niho, e ʻoi aku ka maʻalahi o ka wehewehe ʻana ma mua o ka diametral pitch.
3. Nā Hoʻolālā i Hoʻokumu ʻia i ka Metric:
I nā ʻōnaehana ʻenekinia metric, ʻo ka pitch pōʻai ke anakahi makemake ʻia, e hāʻawi ana i ke kūlike i ka nui o nā kia a me nā helu ʻana.

ʻO ke kiki poepoe kahi palena koʻikoʻi i ke ʻano o nā kia, e hoʻoholo ana pehea e hoʻokaʻawale ʻia ai nā niho a pehea ka maʻalahi o ka launa pū ʻana o nā kia ʻelua. ʻO ka kaohi pololei o kēia ana e hōʻoiaʻiʻo ana i ka hoʻoili neʻe pono, ka liʻiliʻi o ka ʻaʻahu ʻana, a me ka hana hilinaʻi ma nā ʻōnaehana mechanical.

Ma Belon Gear, loea mākou i ka hana ʻana i nā kia kiʻekiʻe me ka geometry niho i hoʻomaikaʻi ʻia—e hōʻoiaʻiʻo ana i ka pitch pōʻai kūlike a me ka hana meshing kīnā ʻole no nā noi makaʻa, hana lopako, a me nā mīkini ʻoihana.
