Mīkini me nā ʻili pōʻai (circular)

Ka ’Ōlelo Aʻo Nui: He kikokikona waihona mōʻaukala kēia, ʻaʻole he kikoʻī mīkini o kēia manawa, loiloi pilikia a i ʻole manual ʻokiʻoki. Pono e nānā ʻia nā ʻano mīkini, nā ʻano, ka nui o ka lau, nā ʻaoʻao niho, ka wikiwiki, ka hoʻokala ʻana, ka laha a me ka hoʻoponopono ʻana i nā lula pili, nā palapala a ka mea hana a me nā lula hana palekana.

ʻAʻole kēia kikokikona i hāʻawi ʻia i nā mīkini, nā pepa hōʻike a i ʻole nā ​​palapala lawelawe a Savo Kusić. ʻO ka hāʻawi o kēia manawa e pili ana i nā puka makani, nā puka a me nā hopena pili.

Ke kumu a me nā ʻano o nā ʻili pōʻai

Hoʻohana ʻia nā mīkini no ka ʻoki poepoe no ka ʻoki ʻana i nā lāʻau i loko o nā papa a me nā kaola, no ka lōʻihi, transverse a i ʻole ke ʻoki diagonal o nā papa e like me nā ana i hāʻawi ʻia. Hoʻohana ʻia nā mīkini ʻike pōʻai no ka ʻoki ʻana i nā lāʻau i loko o nā papa a me nā kaola, no ka ʻoki longitudinal, transverse a oblique paha o nā papa e like me nā ana i hāʻawi ʻia.

No laila, hiki ke hoʻokaʻawale ʻia nā mīkini ʻike pōʻai i nā pūʻulu nui: nā mīkini ʻike pōʻai no ka ʻoki ʻana i nā lāʻau; nā mīkini me kahi ʻike pōʻai no ka ʻoki lōʻihi o nā papa; nā mīkini me ka ʻoki poepoe no ka ʻoki ʻana i nā papa mānoanoa i ʻeleʻele: nā mīkini me ka ʻili pōʻai no ka ʻoki ʻana; nā mīkini me ka ʻike pōʻai no ka ʻoki ʻana i ka longitudinal, transverse a me ka diagonal (universal).

Hiki ke hānai ʻia nā mea e ʻoki ʻia i loko o ka mīkini me ka lima a i ʻole ka mīkini. Hiki ke hoʻokomo i ka mīkini i loko o ka mīkini me nā wili, me nā wili a me nā disc, a me ka tracked. ʻO ka hoʻonohonoho ʻana ka mea kūpono loa, no ka mea e hōʻoiaʻiʻo ana i ka ʻoki ʻana i ka pololei, palekana a me nā ʻenehana palekana no ka hana ʻana i nā mīkini (fig.1).

Kiʻi1: Mīkini ʻili pōʻai me ka hoʻouna kaulahao no ka ʻoki ʻana

Hiki i nā mīkini ʻili pōʻai me hoʻokahi, ʻelua a ʻoi aku paha.

ʻO nā ʻano ʻenehana o nā ʻano mīkini maʻamau me nā saws pōʻai i hāʻawi ʻia ma ka papa 1. No ka ʻoki ʻana i nā papa ma nā kūlana kūkulu kuaʻāina, ua ʻike ʻia kahi pendulum pōʻai o ka brand 4 - KM, i hōʻike ʻia ma ka fig. 2. He maʻalahi ke lawelawe, hoʻohua nui a hāʻawi i ka maikaʻi ʻoki maikaʻi.

Pendulum a me nā ʻili pōʻai puni honua

Kiʻi2: ʻImi ʻokiʻoki pendulum

Papakaukau1: Nā hiʻohiʻona ʻenehana o nā ʻano maʻamau o nā mīkini ʻili pōʻai

I nā hale liʻiliʻi liʻiliʻi no ka hana lāʻau a ma ke ʻano o ke kūkulu ʻana i ke kaiāulu, hoʻohana ʻia nā mīkini honua o ka brand C -2Ma me CU -2no ka oki longitudinal a me ka transverse o na mea. Me kēia ʻano mīkini, hiki ke ʻoki ʻia nā mea lāʻau like ʻole ma kahi kihi. Ma ka fig.3hōʻike ʻia kahi mīkini me ka ʻili pōʻai me ka meaʻai meaʻai no ka ʻoki longitudinal.

Kiʻi3: Poai no ka oki longitudinal me ka hanai mechanical 

Ka helu mōʻaukala o ka huahana

Hiki ke hoʻoholo ʻia ka huahana o kahi pendulum i ʻike ʻia no hoʻokahi neʻe ʻana i nā ʻāpana o nā mea i hana ʻia e ke kumu P =480 Kg(n - m), ma kahi o P ka helu o nā steaks no hoʻokahi neʻe; n - ka helu o nā ʻoki i kēlā me kēia minuke; m - nā ʻoki hoʻohui no ka pae ʻana i ka lae a me ka ʻoki ʻana i nā wahi hemahema. Ke piʻi ka helu o nā ʻoki7i kēlā me kēia minuke, lawe ʻia ka m i like1—2, a i ka nui o na oki ana mai8—12i kēlā me kēia minuke, lawe ʻia ka m ma ke ʻano like2i8; Kg - Coefficient o ka hoʻohana ʻana i ka lā hana, e noʻonoʻo ana i nā pilikia i ka hana ʻana o ka mīkini, ka manawa e hoʻomaha ai nā limahana, ka manawa no ka hoʻoponopono ʻana i ka mīkini, a me nā mea ʻē aʻe.0,93. 

Hiki ke hoʻoholo ʻia ka huahana o ka mīkini me ka ʻike pōʻai i nā ʻāpana o nā mea i hana ʻia i kahi neʻe e like me ke ʻano: P =480a me Kd Kst/Lm, kahi ʻo P - ka hoʻonui ʻana i nā ʻāpana o nā mea i hana ʻia i ka wā hoʻokahi; i - ka hoʻoneʻe wikiwiki; Kd—ka huina hoohana o ka la hookahi i like0,9; Kst - ka helu o ka hoʻohana ʻana i ka mīkini, e like me0,6; L - ka lōʻihi o nā mea, m; m - ka helu awelika o nā ʻoki no hoʻokahi mea.

Pepa a me nā ʻaoʻao niho

Hoʻokaʻawale ʻia nā ʻōpala no nā ʻili pōʻai i nā ʻupena palahalaha, pālua-cone, ʻākau-cone, hema-cone a me nā mea hoʻolālā e like me kā lākou hana ʻana.

Hoʻohana nui ʻia nā ʻili lāʻau pōʻai pālahalaha no ka ʻoki lāʻau longitudinal a transverse. Hāʻawi ʻia ko lākou mau ana ma ka pākaukau.2.

Papakaukau2: Nā ana o nā lau ʻili pōʻai pālahalaha no ka ʻoki lāʻau longitudinal a me ke kuapo

ʻO nā anawaena o nā puka no ka lāʻau saw:20,80,40,50,75a85 mm. Hana ʻia nā ʻili ʻili i ke kila brand89. Hōʻike ʻia nā ʻaoʻao a me nā ana o nā niho o nā lau o nā saws pōʻai ākea no ka ʻoki lāʻau longitudinal a transverse i ka fig.4. I ka papaʻaina.3hāʻawi ʻia ka nui o nā kihi o nā lau o nā niho pololei o nā ʻili pōʻai. Hoʻoholo ʻia ke kiʻekiʻe o ka niho ʻike a me ka radius o ka pōʻai ʻana o ke kihi i loko mai nā ratio like ʻole: Ma ka saw kahi ʻoki longitudinal h = (0,4/0,5)t; No nā pahi ʻoki ʻoki ʻoki h = (0,6/0,9)t; No nā ʻili no ka ʻoki lōʻihi a me ka ʻoki ʻoki h = (0,1/0,15)t.

Kiʻi40: Hōʻike I - IV a me ka nui o nā niho o nā lau ʻili pōʻai pālahalaha

Nā kaʻina hana mālama mōʻaukala a me nā hoʻoponopono

Hoʻokala ʻia nā ʻili ʻili pōʻai ma nā mīkini ʻoki ʻoki ʻoki kūikawā, kahi i loli ʻole ai ka ʻaoʻao a i ʻole ka nui o ka ʻoki ʻoki, ka hoʻokala ʻana, ʻaʻole hoʻi i hoʻololi ʻia ke kihi o loko a me waho. Hana ʻia ka ʻoki ʻana i nā niho hou e nā mīkini kuʻi kūikawā me ke poʻo kūpono. ʻO ka mālama ʻana i ka ʻaoʻao o nā niho a me ka nui o nā mea kihi i hana ʻia me nā template kūikawā a me nā protractors. 

Ma mua o ka hoʻomaʻamaʻa ʻana i nā niho o ka auwai, ka pōʻai a me ka ʻili band, no ka ʻoki ʻana i ka longitudinal, hana ʻia kā lākou hoʻoemi ʻana i kekahi manawa, ʻo ia hoʻi ka hoʻonui ʻana i ka ʻaoʻao mua o nā niho. ʻO ka pōmaikaʻi o ka hoʻopiʻi ʻana ma luna o ka flaring ka mea ʻaʻole e loli ka nui o ka flaring i ka wā o ka hana, hana like ka ʻoki ʻana i ka niho, a wehe ʻia ka puʻu o ka mānoanoa like. Ma luna o ka laulā holoʻokoʻa o ka ʻoki, hiki ke hoʻonui ʻia ka pitch o ka niho e30—40%, me ka hōʻemi ʻole ʻana i ka maikaʻi ʻoki.

I ka wā o ka ʻoki ʻana, ʻike ʻia nā voltages o ka nui a me ke kuhikuhi ʻana i ka ʻili, kahi e alakaʻi ai i ka hana ʻana i nā bulges ma nā wahi nāwaliwali, a pēlā aku. Hoʻohana ʻia kahi anvil, papa no ka nānā ʻana i nā ʻili, nā hamare, nā lula, ka lula no ka nānā ʻana i ka alignment, etc.

Hoʻolaha ʻia nā niho e nā mea hoʻolaha. Lawe ʻia ka nui o ka hōʻike i ka nui o nā hihia0,6i0,75 mmno kekahi ʻaoʻao, me ka nānā ʻole i ka mānoanoa o ka ʻili, akā e noʻonoʻo ana i ke ʻano a me ka haʻahaʻa o ka lāʻau. ʻOi aku ke kiʻekiʻe o ka makū o ka lāʻau, ʻoi aku ka nui o ka swagger o ka ʻili. Hoʻomalu ʻia ka nui o ka laha ʻana o nā niho ʻike e nā template kūikawā.

ʻO ka hoʻokomo ʻana i ka ʻili ʻili i ke kumu mīkini pono e hana ʻia ma lalo o kēia mau kūlana. ʻO nā ʻili pili o nā ʻaoʻao ʻaoʻao o ka saw pono e kū pono i ke kumu ʻōwili. Pono ke kikowaena o ka maka saw me ke kikowaena o ke kumu. Pono e hoʻopaʻa ʻia ka hoʻopaʻa ʻana o ka ʻili ma o nā papa ʻaoʻao. Pono e hoʻonohonoho pono ʻia ka pahi ʻoki i ka ʻike. Pono e hoʻoponopono pololei ʻia nā alakaʻi a me nā mea hoʻokomo i ka slot o ka papaʻaina e like me ka ʻike. ʻAʻole ʻoi aku ka nui o ka ʻae ʻae ʻia ma waena o ka saw a me ke kumu0,2 mm. Inā ʻaʻole i hoʻokō ʻia kēia mau kūlana, loaʻa nā ʻoki haʻahaʻa haʻahaʻa a i kekahi mau hihia ke hiki mai ka mīkini hana hewa.
