N'ime mmepụta ụlọ ọrụ anyị, bolts na-agbajikarị, yabụ gịnị kpatara bolts ji agbaji? Taa, a na-enyochakarị ya site n'akụkụ anọ.
N'ezie, ọtụtụ nkwụsịtụ bolt bụ n'ihi nkwụsịtụ, na ha na-agbajikwa n'ihi nkwụsị. N'ihi na ọnọdụ nke nkwụsịtụ na nkwụsịtụ bụ otu ihe ahụ dị ka nke ike ọgwụgwụ, n'ikpeazụ, anyị nwere ike ịchọta ihe kpatara ya site na ike ọgwụgwụ. N'ezie, ike ike ọgwụgwụ dị ukwuu nke na anyị enweghị ike iche n'echiche ya, na bolts adịghị mkpa ike ike ọgwụgwụ mgbe niile n'oge eji.
Nke mbụ, mgbaji bolt abụghị n'ihi ike ike nke bolt:
Were klaasị M20 × 80 8.8 ike dị elu dịka ọmụmaatụ. Ibu ya bụ naanị 0.2kg, ebe kacha nta ntakiri ibu bụ 20t, nke ruru 100,000 ugboro ibu nke ya. N'ozuzu, anyị na-eji ya naanị iji mechie akụkụ 20kg ma jiri naanị otu puku nke ikike ya. Ọbụna n'okpuru ọrụ nke ndị agha ndị ọzọ na ngwá ọrụ ahụ, ọ gaghị ekwe omume imebi site na otu puku ugboro nke ịdị arọ nke ihe ndị ahụ, ya mere ike nkwụsị nke eriri eriri eri zuru ezu, ọ gaghị ekwe omume imebi ihe mkpuchi ahụ n'ihi ike ezughi oke.
Nke abụọ, mgbaji bolt abụghị n'ihi ike ike ọgwụgwụ nke bolt:
The fastener nwere ike ịtọpụ naanị otu narị ugboro na transverse vibration loosening nnwale, ma ọ kwesịrị ịma jijiji otu nde ugboro ugboro ugboro na ike ọgwụgwụ nnwale. N'ikwu ya n'ụzọ ọzọ, eriri eriri na-atọpụ mgbe ọ na-eji otu puku kwuru puku iri nke ike ike ọgwụgwụ ya, anyị na-ejikwa naanị otu puku iri nke nnukwu ikike ya, ya mere ịtọpụ eriri eriri abụghị n'ihi ike ike ọgwụgwụ nke bolt.
Nke atọ, ezigbo ihe kpatara mmebi nke eriri eriri bụ enweghị isi:
Mgbe ahapụchara ihe nkedo ahụ, a na-emepụta nnukwu kinetic energy mv2, nke na-arụ ọrụ ozugbo na ngwa ngwa na akụrụngwa, na-eme ka ihe nkedo ahụ mebie. Mgbe ihe nkedo mebiri emebi, akụrụngwa enweghị ike ịrụ ọrụ na steeti nkịtị, nke na-eduga n'ihu na mmebi akụrụngwa.
The ịghasa eri nke fastener doro n'okpuru axial ike na-ebibi na bolt na-ewepụ.
Maka ihe nkedo ejiri ike radial, a na-akpacha bolt ahụ na oghere bolt bụ oval.
Anọ, họrọ usoro mkpọchi eriri nwere mmetụta mkpọchi mara mma bụ isi iji dozie nsogbu ahụ:
Were hama hydraulic dịka ọmụmaatụ. Ibu nke hama hydraulic GT80 bụ tọn 1.663, na akụkụ ya bụ 7 bolts nke M42 bolts nke klas 10.9. Ike ike nke bolt nke ọ bụla bụ tọn 110, a na-agbakọkwa ike na-eme ka ọ dị mma dị ka ọkara nke ike ike, na ike na-eme ka ọ dị elu dị narị atọ ma ọ bụ anọ. Otú ọ dị, bolt ga-agbaji, ma ugbu a ọ dị njikere ịgbanwe ka M48 bolt. Isi ihe kpatara ya bụ na mkpọchi bolt enweghị ike idozi ya.
Mgbe bolt na-agbaji, ndị mmadụ nwere ike ikwubi n'ụzọ dị mfe na ike ya ezughị, ya mere ọtụtụ n'ime ha na-agbaso usoro nke ịbawanye ọkwa ike nke dayameta bolt. Usoro a nwere ike ịbawanye ike nke mgbochi nke bolts, na ike esemokwu ya abawanyela. N'ezie, a pụkwara imeziwanye mmetụta mgbochi-loosening. Otú ọ dị, usoro a bụ n'ezie usoro na-abụghị ọkachamara, nke nwere nnukwu ego na obere uru.
Na nkenke, bolt bụ: "Ọ bụrụ na ịtọpụghị ya, ọ ga-agbaji."
