Feem ntau siv cov khoom siv tsav ncej
Qhov kev xaiv ntawm cov khoom siv rau tsav shafts feem ntau yog nyob ntawm lawv qhov chaw ua haujlwm thiab kev ua haujlwm. Nov yog qee cov khoom siv tsav ncej uas siv tau:
Hlau: Hlau yog cov khoom siv dav tshaj plaws rau kev tsav tsheb, muaj lub zog siab thiab hardness. Cov pa roj carbon nruab nrab thiab nruab nrab carbon alloy steel yog dav siv vim lawv cov khoom siv zoo heev. Tom qab kev kho cua sov xws li dov lossis forging, normalizing, lossis quenching thiab tempering, cov hlau no tuaj yeem ua tau raws li lub zog thiab hnav tsis kam ntawm cov ncej tsav.
Aluminium Alloy: Aluminium alloy tsav shafts muaj qhov hnyav dua thiab zoo corrosion kuj, ua rau lawv tsim nyog rau cov ntawv thov kom txo qhov hnyav, xws li tsheb thiab aerospace industries. Txawm li cas los xij, vim lawv lub zog qis dua, siab - lub zog alloys lossis cov qauv tsim tshwj xeeb yog xav tau los txhim kho kev thauj khoom - cov kabmob muaj peev xwm.
Titanium Alloy: Titanium alloys muaj lub zog siab, qhov hnyav, thiab kev tiv thaiv corrosion zoo heev, ua rau lawv tsim nyog rau kev tsim khoom siab -kev ua haujlwm tsav. Txawm li cas los xij, lawv cov nqi siab dua thiab kev ua haujlwm tsis zoo txwv lawv daim ntawv thov hauv qee thaj chaw.
Tsis tas li ntawd, lwm yam ntaub ntawv xws li ceramics thiab composites kuj yog siv rau tsav shafts nyob rau hauv tej kev siv. Kev xaiv ntawm cov ntaub ntawv no yuav tsum tau xav txog ntau yam xws li kev ua haujlwm, tus nqi, thiab ib puag ncig kev ua haujlwm.
Cov khoom siv thiab kev kho cua sov yuav tsum tau ua rau Tsav Shafts
Txhawm rau kom ntseeg tau tias kev ua haujlwm thiab kev pabcuam lub neej ntawm cov ncej tsav, ntxiv rau kev xaiv cov khoom tsim nyog, kev kho cua sov tsim nyog kuj tseem yuav tsum tau ua. Cov hauv qab no yog qee qhov kev kho cua sov uas yuav tsum tau ua thiab cov txheej txheem:
Quenching thiab Tempering: Rau cov ncej tsav ua los ntawm nruab nrab carbon steel thiab nruab nrab carbon alloy steel, quenching thiab tempering feem ntau yuav tsum tau txhim kho lawv cov khoom siv kho tshuab tag nrho. quenching thiab tempering muaj ob kauj ruam: quenching thiab siab -kub tempering, uas ua rau cov khoom ua tau zoo sib npaug ntawm lub zog thiab toughness.
Surface Quenching: Txhawm rau txhim kho qhov tawv tawv thiab hnav tsis kam ntawm cov ncej tsav, qhov quenching feem ntau ua rau cov khoom hnav yooj yim xws li cov ntawv sau. Txoj kev no ua kom ntseeg tau tias tus tsav ncej tswj kev ua haujlwm zoo nyob rau hauv cov khoom hnyav thiab siab - kev sib hloov ceev.
Carburizing thiab Nitriding: Rau cov ncej tsav uas yuav tsum tau muaj zog dua thiab hnav tsis kam, cov txheej txheem kev kho cua sov xws li carburizing lossis nitriding tuaj yeem siv. Cov txheej txheem no tuaj yeem ua kom cov pa roj carbon lossis nitrogen ntau ntxiv ntawm cov khoom siv saum npoo, yog li txhim kho nws cov tawv tawv thiab hnav tsis kam.
