ʻO ke kū'ē uila Spiral Nicr Alloy 1 - 5 Mohm no nā mea hoʻomehana ea

1. Ka Wehewehe Laulā o nā Mea Hana

ʻO Constantanhe mea hoʻohuihui keleawe-nickel i ʻike ʻia hoʻiʻEureka,Hoʻomaka, a meWaʻa Hoʻokele. ʻO ka maʻamau, he 55% keleawe a me 45% nickel. ʻO kona hiʻohiʻona nui kona resistivity, kahi e mau ana ma luna o nā ʻano mahana like ʻole. Ua ʻike ʻia nā mea hoʻohui ʻē aʻe me nā coefficients mahana haʻahaʻa like, e like me ka manganin (Cu₈₆Mn₁₂Ni₂).

No ke ana ʻana o nā ʻano nui loa, 5% (50 000 microstrian) a i ʻole ma luna, ʻo ka constantan annealed (P alloy) ka mea grid i koho maʻamau ʻia. ʻO Constantan ma kēia ʻano he mea nui loaductile; a, i nā lōʻihi ana o 0.125 ʻīniha (3.2 mm) a ʻoi aku ka lōʻihi, hiki ke hoʻopaʻa ʻia i >20%. Eia nō naʻe, pono e hoʻomanaʻo ʻia, ma lalo o nā ʻano cyclic kiʻekiʻe, e hōʻike ka P alloy i kekahi loli resistivity mau loa me kēlā me kēia pōʻaiapuni, a hana i kahi mea like.ʻoleka neʻe ʻana o ke ana o ke kaumaha. Ma muli o kēia ʻano, a me ke ʻano o ka hāʻule ʻana o ka grid mua me ka hoʻopololei pinepine ʻana, ʻaʻole i ʻōlelo pinepine ʻia ka P alloy no nā noi strain cyclic. Loaʻa ka P alloy me nā helu STC o 08 a me 40 no ka hoʻohana ʻana ma nā metala a me nā plastics, kēlā me kēia.

2. Hoʻolauna Puna a me nā noi

He pūnāwai torsion wili, a i ʻole hairspring, i loko o ka uaki hoʻāla.

He pūnāwai volute. Ma lalo o ke kaomi ʻana, paheʻe nā ʻōwili ma luna o kekahi i kekahi, no laila e hāʻawi ana i ka huakaʻi lōʻihi.

Nā pūnāwai volute kū pololei o ka pahu Stuart

Nā pūnāwai hoʻohaʻahaʻa i loko o kahi mea kani laina i pelu ʻia.

He pā torsion i wili ʻia ma lalo o ke kaumaha

Puna lau ma luna o kahi kalaka
Hiki ke hoʻokaʻawale ʻia nā pūnāwai ma muli o ke ʻano o ka hoʻopili ʻia ʻana o ka ikaika ukana iā lākou:

Puna hoʻolohi/hoʻolōʻihi - ua hoʻolālā ʻia ka pūnāwai e hana me kahi ukana hoʻolohi, no laila e kīkoʻo ka pūnāwai i ka wā e kau ʻia ai ka ukana ma luna.
Puna kōmiʻi - ua hoʻolālā ʻia e hana me kahi ukana kōmiʻi, no laila e pōkole ka pūnāwai i ka wā e kau ʻia ai ke ukana iā ia.
Puna torsion - ʻaʻole e like me nā ʻano i luna aʻe nei kahi e lilo ai ka ukana i ikaika axial, ʻo ka ukana i hoʻopili ʻia i kahi pūnāwai torsion he ikaika torque a wili paha, a ke wili nei ka hopena o ka pūnāwai ma o kahi kihi i ka wā e hoʻopili ʻia ai ka ukana.
ʻO ka pūnāwai mau - ʻo ke kaumaha i kākoʻo ʻia e mau ana ia i ka like ma o ke kaʻina hana deflection.
Puna loli - loli ke kūpaʻa o ke koʻi i ka ukana i ka wā o ke kaomi ʻana.
Puna ʻoʻoleʻa loli - hiki ke hoʻololi ʻia ke kū'ē o ke koil i ka ukana no ka laʻana e ka ʻōnaehana kaohi, hoʻololi kekahi ʻano o kēia mau pūnāwai i ko lākou lōʻihi e hāʻawi ana i ka hiki ke hana.
Hiki nō hoʻi ke hoʻokaʻawale ʻia ma muli o ko lākou ʻano:

Puna pālahalaha - ua hana ʻia kēia ʻano me ke kila puna pālahalaha.
Puna mīkini - hana ʻia kēia ʻano puna ma ka mīkini ʻana i ka ʻōpae me ka hana lathe a/a i ʻole ka wili ʻana ma mua o ka hana wili. Ma muli o ka mīkini ʻana, hiki i ka puna ke hoʻokomo i nā hiʻohiʻona ma waho aʻe o ka mea elastic. Hiki ke hana ʻia nā puna mīkini i nā hihia ukana maʻamau o ka compression/extension, torsion, etc.
Puna serpentine - he zig-zag o ka uea mānoanoa - hoʻohana pinepine ʻia i nā hale noho/lako hale hou.
