He aha ke ʻano ʻo Helical Torsion Spring?
You see a tightly wound spring on a device's hinge and need to understand its function. Akā me ka ʻole o nā huaʻōlelo kūpono, ʻAʻole hiki ke loaʻa kahi pani a hoʻolālā paha me ia.
ʻO ka pūnāwai torsion helical kahi mea i hoʻolālā ʻia e hana me ka wili, a i ʻole torsion. Mālama ʻo ia a hoʻokuʻu i ka ikehu rotational ma o kona kino wili a hoʻohana i kona mau wāwae e hoʻopili i ka torque i kahi mīkini pili., e like me ke poʻi, lever, a i ʻole ʻōnaehana hoʻohālikelike.
I koʻu hale hana, hana mākou i mau tausani o kēia mau pūnāwai i kēlā me kēia lā no nā ʻano ʻoihana āpau. ʻOiai lākou e nānā maʻalahi, ʻO ke ala a lākou e hoʻoulu ai i ka ikaika rotational he wahi akamai o ka ʻenekinia. He nui ka poʻe e huikau iā lākou me nā punawai hoʻopaʻa a hoʻonui paha, akā, ʻokoʻa loa kā lākou hana. They don't push or pull; huli lakou. Let's look closer at how this simple helix creates torque and why its design is so critical.
Pehea e hana ai ka punawai Torsion i ka ikaika?
Pono kāu hoʻolālā i ka ikaika hoʻihoʻi rotational, but you're unsure how a simple spring provides it. ʻO ka loaʻa ʻana o kēia hewa hiki ke alakaʻi i kahi mīkini hiki ʻole ke pani a paʻa paha.
Hoʻopuka ka pūnāwai torsion i ka ikaika ke hoʻokuʻu ʻia kona mau wāwae a kaʻawale paha, causing the spring's coils to either tighten or open. Hana kēia hana wili torque[^1]—he ikaika hoʻololi e hoʻihoʻi i ka pūnāwai i kona kumu, kūlana wili ʻole.
ʻO kekahi o nā mea mua aʻu i aʻo ai e pili ana i nā pūnāwai torsion he lula hiki ʻole ke haki: Pono e hoʻolālā ʻia e hoʻouka ʻia i kahi ala e hoʻopaʻa ai i nā coils. Ke makani ʻoe i ka pūnāwai paʻa, emi iki ke anawaena uwea a lōʻihi ka lōʻihi o ke kino, akā, aia ka mea ma lalo o ke kaumaha. Inā ʻoe e hoʻāʻo e hoʻouka i ka pūnāwai ma kahi ala e wehe ai i nā ʻōwili, lilo ke koʻikoʻi i hiki ʻole ke ʻike ʻia a hiki ke hana i ka pūnāwai e kuʻi a haki paha i ka wā mua. He kumu hoʻolālā kumu kēia a mākou e hahai ai no kēlā me kēia pūnāwai torsion a mākou e hana ai.
ʻO ke kinona o ka ikaika rotational
The spring's power comes from the resistance of its wire to being twisted. Hoʻokumu kēia i kahi mana rotational hiki ke wānana a hiki ke hana hou, a i ʻole torque[^1].
- Torque a me ka Angular Deflection: ʻO ka lōʻihi o kou hoʻohuli ʻana i nā wāwae o kahi punawai torsion mai kona "noa" kūlana, ka nui aku torque[^1] hooikaika. He laina laina kēia pilina. Ka nui o torque[^1] ʻike ʻia ʻo ia no kēlā me kēia degere o ka hoʻololi ʻana puna puna[^ 2]. Hāʻawi kēia i nā ʻenekinia e kuhikuhi i kahi puna e hāʻawi ai, ʻo kahi laʻana, 5 iniha-pauna o torque[^1] ke wehe ʻia kahi poʻi 90 degere.
- ʻO ke koʻikoʻi o nā wāwae: ʻO nā wāwae, a i ʻole nā lima, ʻo nā ʻāpana o ka pūnāwai e hoʻoili i ka torque[^1] i kāu huahana. ʻO ko lākou lōʻihi, kinona, a hiki ke hoʻopilikino ʻia ke kihi. Hiki iā mākou ke kulou iā lākou i nā wāwae pololei maʻalahi, makau, puka lou, a i ʻole nā ʻano paʻakikī i mea e maʻalahi ai ka hoʻokomo ʻana a hōʻoia i ke komo pono ʻana me nā ʻāpana male.

Aia i hea nā pūnāwai Torsion i hoʻohana mau ʻia?
You're trying to figure out if a torsion spring is the right choice for your product. ʻIke ʻoe i ke kumumanaʻo akā ke paʻakikī nei e ʻike i kāna mau noi honua maoli a me nā pono.
Hoʻohana ʻia nā pūnāwai torsion i nā huahana he nui e koi ana i ka hoʻihoʻi ʻana i ke kikowaena a i ʻole ka hana counterbalance. ʻO nā hiʻohiʻona maʻamau he mau lole lole, nā papa ʻokiʻoki, hale hale kaʻa puka, puka kaʻa, a me nā poʻi mea hana e like me nā mea ma luna o nā mea holoi a puhi paha.
Hoʻomanaʻo wau i ka hana ʻana i kahi papahana no ka mea hana i nā mea lapaʻau kiʻekiʻe. Pono lākou i kahi liʻiliʻi, punawai torsion hilinaʻi no ka poʻi o kahi pā mea hana maʻemaʻe. Pono ka poʻi e ʻoluʻolu, paʻa iā ia iho hāmama ma 90 degere, a pani malie me ka paa ole. Ua hoʻopau mākou i ka hoʻolālā ʻana i kahi pūnāwai torsion ʻelua-ʻo ia hoʻi ʻelua pūnāwai i wili ʻia ma nā ʻaoʻao ʻē aʻe a pili i waena.. Hāʻawi kēia i kahi kaulike kūpono a paʻa torque[^1] i kūpono i kā lākou mau koi pololei.

He aha nā mea i hana ʻia mai nā pūnāwai Torsion?
Pono ʻoe i pūnāwai torsion no kāu noi, but you're unsure which material to choose. Ke hopohopo nei ʻoe i ka ʻōpala, luhi, a i ʻole e nalowale ana ka ikaika o ka puna i ka manawa, ʻoi aku ma kahi ʻano koi.
ʻO ka hapa nui o nā pūnāwai torsion i hana ʻia mai nā kila puna kalapona kiʻekiʻe e like me ka uea mele a i ʻole ka uea ʻaila. No nā noi e koi ana i ka pale ʻana i ka corrosion a i ʻole ka hoʻohana ʻana i nā wahi maʻemaʻe, kila kohu ʻole (ʻano maʻamau 302, 304, a i ʻole 316) ʻo ia ke koho i makemake ʻia.
ʻO ke koho waiwai kekahi o nā hoʻoholo koʻikoʻi a mākou e hana ai i ka hoʻomaka ʻana o kekahi papahana. It's not just about corrosion. ʻo kahi laʻana, uea mele i maikai luhi ola, 'o ia ho'i, hiki ke ho'okele 'ia he mau miliona me ka haki 'ole, aka, hiki wale ke ehu. No laila no kahi mīkini i loko i kahi lumi maloʻo, it's perfect. Akā no ka laiki waho, ʻO ke kila kila ka mea hiki ke koho, ʻoiai inā ʻoi aku ke kumukūʻai. Hoʻopili pū mākou i nā hoʻopau ʻili e like me ka zinc plating a i ʻole ka pauka e hoʻohui i ka pale corrosion i nā pūnāwai kila kalapona, hāʻawi i kā mākou mea kūʻai i ke kaulike ma waena o ke kumukūʻai a me ka lōʻihi.

- Na Kiekie-Carbon Steel:
- Pūnaewele Music (Astm A228): He ikaika kiʻekiʻe, ke kila huki anu i ʻike ʻia no kona kūpaʻa luhi maikaʻi. It's ideal for high-cycle applications where corrosion is not a concern.
- Uea-Aila (ASTM A229): He kila puna kumu nui i mālama ʻia i ka wela no ka ikaika. It's more economical than music wire and is great for larger springs that don't require an extremely high cycle life.
