He aha ka Axial Torsion Spring?

Pono ʻoe i kahi pūnāwai e wili, akā ʻo ka huaʻōlelo "axial torsion spring" huikau. You're unsure if it's a special component or just another name for a standard torsion spring.

ʻO kahi pūnāwai torsion axial ka punawai helical maʻamau i hoʻolālā ʻia e hāʻawi i ka ikaika rotational, a i ʻole torque. Hoʻohana ia a puni kahi kumu a i ʻole arbor, with the force being applied in a circular path perpendicular to the spring's central axis. ʻO ia ke ʻano maʻamau o puna torsion[^1].

I koʻu mau makahiki o ka hana ʻana, I've noticed that engineers, ʻoi aku ka poʻe hou i ka hoʻolālā mīkini, i kekahi manawa hopu ʻia i nā huaʻōlelo. Hele mai lākou iaʻu e noi ana i kahi "axial" punawai, me ka noʻonoʻo e hana ana ka ikaika ma ke koʻi, e like me ka punawai kaomi. He kuhi hewa iki ka inoa. ʻO ka "axis" ʻo ia ka mea i kau ʻia ai ka pūnāwai ma; ʻo ka hana āna e hana ai he rotational. ʻO ka wehewehe ʻana i kēia wahi maʻalahi ka hana mua i ka hoʻolālā ʻana i kahi kūleʻa, ʻāpana hilinaʻi no kā lākou huahana.

Pehea ka ʻokoʻa mai kahi pūnāwai hoʻonui a i ʻole ka hoʻopili ʻana?

ʻIke ʻoe i kahi pūnāwai wili a manaʻo paha e hana like nā ʻōwili āpau. This can lead to selecting the completely wrong type of spring for your application's force requirements.

Hana ʻia kahi pūnāwai torsion axial ma ka wili ʻana (LARAINA), oiai ke kaomi a puna hoʻonui[^ 2]s hana me ka ikaika laina (hoʻokuke a huki). ʻOkoʻa loa kā lākou kumu kumu a me ke ʻano o ka mālama ʻana i ka ikehu.

Hoʻomanaʻo wau i kahi hoʻomaka e hoʻomohala ana i kahi hāmeʻa mea kūʻai liʻiliʻi me kahi poʻi pop-up. Ua hoʻohana kā lākou prototype mua i kahi pūnāwai kaomi liʻiliʻi e pana i ka poʻi e wehe, akā, ua ʻike ʻia ʻo ia he haʻalulu a ʻaʻole mālama ʻia. Ua hoʻouna mai lākou i kā lākou hoʻolālā, a hiki iaʻu ke ʻike koke e hoʻāʻo ana lākou e hoʻoponopono i kahi pilikia rotational me kahi hopena laina. Ua pani mākou me kahi liʻiliʻi axial torsion puna[^ 3] i hoʻopili ʻia a puni ka pine hinge. Wehe aʻela ka poʻi me ka maʻalahi, ʻoni hoʻomalu. It was a perfect example of how choosing the right type of force—rotational instead of linear—completely changed the user's experience.

Ho'ākāka 'o Force Direction i ka Puna

Hōʻike ka inoa o kahi puna iā ʻoe pehea i hoʻolālā ʻia ai e hoʻohana ʻia. ʻO ka hoʻomaopopo ʻana i kēia ʻokoʻa kumu ka mea nui loa o ka koho puna.

• Tortion springs (ʻO ka wiliwili): Hoʻouka ʻia kēia mau pūnāwai ma ka hoʻohuli ʻana i ko lākou mau wāwae. Hoʻokumu kēia i ke koʻikoʻi piʻo i ka uea, ka mea e hoʻoulu ai i ka torque hoʻihoʻi. E noʻonoʻo i kahi ʻiole maʻamau. The coiled spring doesn't compress; wili ʻo ia e hoʻoikaika i ka pahele.
• Nā punawai compression (Puhi Pukiki): Hoʻolālā ʻia kēia mau pūnāwai e ʻomi ʻia. Mālama lākou i ka ikehu ke kaomi ʻia a hoʻokuʻu iā ia ma ka hoʻokuʻu ʻana i hope, pale ana i ka ikaika compressive. A pogo stick or a vehicle's suspension uses compression springs.
• Nā puna wai (Kaha Huki): Hoʻolālā ʻia kēia mau pūnāwai e ʻōloi. Loaʻa iā lākou nā makau a i ʻole nā ​​puka lou ma nā wēlau a mālama i ka ikehu ke huki ʻia, ka hoʻokuʻu ʻana ma ka huki ʻana i hope. ʻO nā pūnāwai ma ka puka hale kaʻa a i ʻole kahi trampoline he mau hiʻohiʻona maʻamau.

He aha nā kumu hoʻolālā koʻikoʻi no kahi pūnāwai Axial Torsion?

Pono ʻoe e kauoha i kahi puna torsion maʻamau, but you're not sure which details are critical. Providing incomplete information can lead to a spring that doesn't work or fails quickly.

ʻO nā kumu hoʻolālā koʻikoʻi loa ke kuhikuhi makani (lima ʻākau a lima hema paha), ka hoʻonohonoho ʻana o nā wāwae, a me ka torque i koi ʻia ma kahi kihi kikoʻī o ka hoʻololi ʻana. Hōʻike kēia mau mea i ke ʻano a me ka hana o ka puna.

ʻO kekahi o nā hewa maʻamau aʻu i ʻike ai ma nā kaha kiʻi, ʻo ia ka nalo ʻana a i ʻole ka pololei o ka makani. Ua kauoha kekahi mea kūʻai 10,000 nā pūnāwai no kahi hui hili. The drawing didn't specify the wind direction, no laila ua manaʻo ʻia he makani ʻākau maʻamau. Ua ʻike ʻia ko lākou hui ʻana e pono ke hoʻouka ʻia ka pūnāwai ma kahi ala e hiki ai hoʻomaha ka wili. Ma ka hopena, ʻaneʻane ʻaʻohe ikaika o nā pūnāwai a hāʻule koke. Pono mākou e hana hou i ka pūʻulu holoʻokoʻa me ka makani hema. He haʻawina kumu kūʻai ia i ke koʻikoʻi o kahi kikoʻī liʻiliʻi ma ke kiʻi.

Nā kikoʻī e hoʻoholo ai i ka hana

A puna torsion[^1]'s success depends on getting three key areas right.

• Kuhikuhi makani: Pono e hoʻohana mau ʻia kahi pūnāwai torsion ma ke ʻano e hoʻopaʻa paʻa ai ka wili. ʻO ka hoʻouka ʻana iā ia ma ka ʻaoʻao ʻē aʻe e hoʻokuʻu ʻia, deform mau loa, a lilo kona ikaika. Pono ʻoe e wehewehe inā pono ʻoe i ka lima ʻākau (ka uaki) a i ʻole ka lima hema (kūʻē i ka uaki) makani.
• Hoʻonohonoho wāwae: ʻO nā wāwae ke ʻano o ka hoʻoili ʻana o ka pūnāwai i kona torque i kāu mau ʻāpana. ʻO ko lākou lōʻihi, kinona, a me ka huina ma waena o lākou (ka huina manuahi) Pono e wehewehe pono ʻia i hiki ke kau pono ʻia a launa pū me kāu hui e like me ka mea i manaʻo ʻia.
• Mea a me Torque: The spring's material and wire diameter determine its strength. Pono ʻoe e kuhikuhi i ka nui o ka torque āu e pono ai ma kekahi pae o ka hoʻololi (E.g., "10 N-mm o ka torque ma 90 degere"). Hōʻike kēia iā mākou i ka ikaika o ka puna. Maikaʻi ka uea mele no ka hoʻohana maʻamau, ʻoiai pono ke kila kila no nā kaiapuni corrosive.

He aha nā noi maʻamau no nā pūnāwai Axial Torsion?

Maopopo iā ʻoe ka mechanics, but you're having trouble picturing where these springs are used. Seeing real-world examples can help you decide if it's the right solution for your design.

Axial puna torsion[^1]Hoʻohana ʻia nā s i nā mīkini maʻamau he nui e koi i ka ikaika hoʻihoʻi maʻalahi. Loaʻa iā lākou ma nā hinges, nā levers, nā kaulike, a me nā kiʻi o nā ʻano a pau.

One of the most impressive uses of torsion springs I've seen was in a piece of medical equipment. He ʻano hoʻohālikelike ia no ka lima nānā koʻikoʻi e neʻe ʻia a hoʻonohonoho hou ʻia e nā kauka a me nā kahu hānai.. He hui nui, axial ikaika puna torsion[^1]s ua hūnā ʻia i loko o ka hui nui. Ua hoʻolālā maikaʻi ʻia lākou e hoʻopau i ke kaumaha o ka monitor, no laila ua aneane ʻole ke kaumaha i kou neʻe ʻana. Ua hōʻike ʻia pehea e hiki ai ke hoʻohana ʻia kēia mau mea maʻalahi no ka hana ʻana i ka mana o ka neʻe ʻana a me ka hoʻohana.

Ma na wahi a pau e nana ai

Ke ʻike ʻoe i ka mea e ʻimi ai, you'll start seeing these springs everywhere. ʻO kā lākou maʻalahi a me ka hilinaʻi e hoʻolilo iā lākou i mea e hele ai i ka hopena no ka ikaika rotational.

• Nā mea hale: ʻO nā hiʻohiʻona maʻalahi loa nā punawai maʻalahi i nā lole lole a me nā ʻiole kahiko. Hoʻohana pū ʻia lākou i loko o nā ʻeke o kekahi mau puka keʻena e kōkua iā lākou e pani mālie.
• Lako Keena: Hoʻohana ʻia kēlā kiʻi metala ma ka papa paʻi e a puna torsion[^1]. Hoʻohana pinepine ka poʻi ma kahi scanner kahiko a paʻi paha e paʻa iā ia e wehe a kōkua paha i ka pani ʻana.
• ʻOihana a me kaʻa kaʻa: Hoʻohana ʻia lākou i nā lima puka kaʻa, mīkini pahu pahu, a me nā ʻano laiki a me nā lever i nā mīkini. Ma nā noi kaumaha, Hoʻohana ʻia lākou e like me nā counterbalance no nā poʻi kaumaha a me nā ramps, e like me ka ʻīpuka hale kaʻa.
