ʻO kekahi ʻike e pili ana i ke kaula

1 、 Wehewehe ʻana i ke kaula

ʻO ka milo e pili ana i ke ʻano ʻōniʻoniʻo, hoʻomau mau ʻia me kahi ʻāpana keʻa kikoʻī i hana ʻia ma ka ʻili o kahi kumu cylindrical a conical paha. Hoʻokaʻawale ʻia nā kaula i loko o nā milo cylindrical a me nā milo conical e like me ko lākou ʻano makua;

E like me kona kūlana i loko o ke kino makua, ua maheleia i loko o waho a me loko, a ma muli o kona cross-sectional shape (niho shape), ua maheleia i triangular milo, rectangular milo, trapezoidal milo, serrated threads, a me na mea e ae. ʻano lola kūikawā.

2、 ʻIke pili

ʻO ka hana ʻana i ka milo he ʻano hoʻomau mau ʻia me ke ʻano niho kikoʻī i hana ʻia ma ka helix ma kahi cylindrical a conical paha. ʻO ka protrusion e pili ana i ka ʻāpana paʻa ma nā ʻaoʻao ʻelua o ke kaula.

ʻIke ʻia he niho. I ka hana ʻenehana, ʻoki ʻia nā milo ma ke kumu cylindrical (a i ʻole ka lua o loko) me ka hoʻohana ʻana i kahi mea hana a i ʻole huila wili.

I kēia manawa, huli ka mea hana a neʻe ka mea hana i kahi mamao ma ke axis o ka mea hana. ʻO nā kaha i ʻoki ʻia e ka mea hana ma ka mea hana he mau kaula. Ua kapa ʻia ka milo i hana ʻia ma ka ʻili o waho he milo waho. ʻO nā kaula i hana ʻia ma luna o ka ʻili o ka lua i loko, ua kapa ʻia ʻo ia he milo o loko.

ʻO ke kumu o kahi milo ka helix ma ka ʻili o kahi axis pōʻai. Hiki ke hoʻokaʻawale ʻia ka profile thread i nā ʻano like ʻole

Nui nā ʻano o nā profile thread:

Loko maʻamau (meʻa triangular): ʻO kona ʻano niho he huinakolu kūlike, me ka huina niho he 60 degere. Ma hope o ka hoʻopaʻa ʻia ʻana o nā kaula i loko a me waho, aia kahi ʻāpana radial, i māhele ʻia i loko o nā kaula koʻikoʻi a maikaʻi e like me ka nui o ka pitch.

Loko paipu: ʻO ke ʻano niho o nā lola paipu i hoʻopaʻa ʻole ʻia he huinakolu isosceles, me ka huina niho he 55 degere a me ke kihi poʻe nui ma ka piko o ka niho.

ʻO nā hiʻohiʻona niho o nā kaula paipu i hoʻopaʻa ʻia e like me nā loina paipu i hoʻopaʻa ʻole ʻia, akā aia ma ka paia paipu conical, me kahi niho trapezoidal isosceles a me kahi kihi niho o 30 degere.

ʻO ke kaula Trapezoidal: ʻO kona ʻano niho he trapezoid isosceles, me kahi kihi niho o 30 degere, a hoʻohana nui ʻia i nā mīkini wili no ka lawe ʻana i ka mana a i ʻole ka neʻe.

Loko huinahā: He huinahā kona ʻano niho, a ua like ka huina niho me 0 degere. Loaʻa iā ia ka maikaʻi o ka hoʻouna ʻana, akā haʻahaʻa haʻahaʻa ke kikowaena pololei a nāwaliwali ka ikaika o ke aʻa.

Loko serrated: ʻO kona ʻano niho he ʻano trapezoidal like ʻole, me kahi kihi ʻaoʻao niho o 3 degere ma ka ʻili hana. ʻO ke kumu o ke kaula waho he kihi poʻe nui, a ʻoi aku ka maikaʻi o ka hoʻouna ʻana a me ka ikaika ma mua o nā kaula trapezoidal.

Eia kekahi, aia kekahi mau mea kiko'ī kūikawā'ē aʻe, e like me ka V-shaped threads, Whitney threads, round threads, etc. He mau hiʻohiʻona ko kēia mau hiʻohiʻona a kohoʻia a hoʻohanaʻia e like me nā hiʻohiʻona noi likeʻole.
