Nā huahana

Hoʻohana ʻia kēia mau ʻāpana i ka hui pū ʻana me kahi wili i loaʻa kahi lua radial pre-drilled.Hoʻopili ʻia ka nut a kau ʻia kahi pine ma nā notches a me ka lua o ka wili, e pale ana i ka huli ʻana o ka nati.

Hiki ke hoʻohana ʻia kekahi mau ʻano pine no kēia kumu.Aia kēia mau mea:

ʻO kahi pine cotter, i ʻike ʻia hoʻi he pine ʻokiʻoki - kahi mea hoʻopaʻa me nā māhoe māhoe, a ma hope o ka hoʻokomo ʻia ʻana e hoʻokaʻawale ʻia e pale i ka wehe ʻana.

ʻO kahi R-clip, ʻike ʻia hoʻi he pine cotter hairpin a i ʻole hitch pin - he mea hoʻopaʻa metala me hoʻokahi wāwae pololei i hoʻokomo ʻia i loko o ka lua a hoʻokahi wāwae i hoʻopaʻa ʻia e paʻa i waho o ka nati.

Palekana a i ʻole uea paʻa - he uea i hele ma nā notches a me ka lua, a laila wili, a heleuma e hoʻopaʻa i ka nut.

Me ʻeono notches i hoʻokaʻawale ʻia ma nā wā 60-degere, hiki ke laka wale ʻia ka nut castellated ma kahi e pili ai kahi notch me ka lua.Ma hope o ka torquiing pololei, pono e hoʻohuli hou i ka nati i 30 degere (ma kēlā me kēia ʻaoʻao) e ʻimi i ka lua.

ʻOiai ʻaʻole hiki ke hoʻoponopono maikaʻi i ka torque, ʻoi aku ka maikaʻi o nā nati castellated i nā noi haʻahaʻa-torque.ʻAʻole kūpono lākou i nā noi e koi ana i kahi preload kikoʻī.

Hoʻopili pinepine ʻia nā nati Castellated me ka Unified inch fine (UNF) a i ʻole Unified inch coarse series (UNC) me ke anawaena o ka milo - maʻamau mai 1/4 a 1-1/2-ʻīniha i nā laula a me nā kiʻekiʻe o nā hua.

ʻO ka nati castellated he poʻomanaʻo poʻokela o kahi anawaena liʻiliʻi ma kahi o nā notches, me kahi kiʻekiʻe kiʻekiʻe ma mua o ka nati maʻamau o kona nui.Ua like ia me ka nati slotted akā ʻo ka ʻāpana poepoe i hōʻike ʻia ma ka nati castellated e hiki ai i ka pine ke hoʻopaʻa paʻa i ka nati ma mua o ka hiki me ka nati slotted.
