Kev txhim kho ntawm screws

Kev txhim kho ntawm Screws tuaj yeem faib ua cov theem hauv qab no:

Keeb Kwm thiab Kev Loj Hlob
Screws, raws li lub khawm khawm, keeb kwm yav dhau los tim nkij teb chaws ib puag thaum ub nyob rau xyoo pua 3 BC. Lub sijhawm ntawd, cov neeg siv cov ntaub ntawv xws li ntoo thiab pob zeb rau kev tsim kho thiab tsim khoom, tab sis txoj kev nrawm nrawm tau tsis ntseeg tau. Txhawm rau kom daws tau cov teeb meem no, cov Greeks thaum ub tsim ib txoj kev ntawm kev sib txuas ua ke ntawm cov ntoo hlau nrog cov ntoo ntoo nrog cov ntsia hlau. Cov qauv tsim no yog qhov yooj yim thiab ingenious, tso lub hauv paus rau kev txhim kho ntxiv ntawm cov ntsia hlau.
Kev loj hlob los ntawm nruab nrab hnub nyoog rau cov sijhawm niaj hnub
Hauv Nrab Hnub nyoog, Kws Ntoo Siv Cov Ntoo Ntoo lossis Hlau Rau Tes Rau Txuas Rooj Tog thiab Ntoo Vaj Tsev. Nws tsis yog kom txog thaum xyoo pua 15 uas Ntsia cov ntsia hlau pib tsim cov ntsia hlau nrog cov xov hlau kauv nrog cov xov hlau, uas tuaj yeem txuas tau yooj yim dua. Nyob ib ncig ntawm 1780, cov ntsia hlau ntsees (cov ntsia hlau ntswj) tshwm sim hauv London, thiab craftsmen pom tias zuaj screws nrog hatlering tau zoo tshaj li rauj nrog rauj nrog rauj.
Hauv 1797, Henry Maudsley tsim cov All-Hlau Precision Xov Kws Dhos hauv UK; Cov nram qab no xyoo, Wilkinson ua ib lub txiv ntoo thiab ntsia liaj qhov rooj raug hauv Tebchaws Meskas. Ob lub tshuab tuaj yeem tsim cov txiv ntoo universal thiab bolts.

Cov qauv thiab kev txhim kho hauv kev muaj hnub nyoog muaj zog
Nrog kev tawm tsam ntawm kev kho cov kev hloov pauv, kev tsim cov screws tau maj mam ua tiav cov qauv thiab kev tsim kho tshuab. Qhov kawg ntawm lub xyoo pua puv 19, ua cov ntsia hlau ntawm cov screws tau maj mam qauv, thiab ntau ntawm cov xov uas tau sib koom tes, ua rau cov ntsia hlau sib pauv tau. Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, cov ntaub ntawv thiab tsim cov txheej txheem ntawm cov screws kuj tau txhim kho txuas ntxiv. Tsoos cov ntsia hlau feem ntau yog ua los ntawm cov ntaub ntawv hlau, thiab tom qab ntawd steel screws tau tsim muaj zog thiab corrosion tsis kam. Nyob rau hauv xyoo tsis ntev los no, cov ntaub ntawv tshiab xws li Stainless Hlau Screws thiab Aluminium Screws kuj tau thov kom tau raws li cov kev xav tau ntawm cov yam ntxwv ntawm ntsia hlau sib txawv. Hais txog kev tsim thev naus laus zis, kev ua tiav cov thev naus laus zis xws li txias taub hau thiab kev kho cua sov tau txhim kho cov screws.
Cov ntawv thov niaj hnub thiab yav tom ntej
Cov screats niaj hnub niaj hnub siv nyob rau hauv ntau daim teb, suav nrog kev tsim kho, kev lag luam lag luam, cov screws yog siv los kho cov txheej txheem tsev thiab ntau yam khoom siv; hauv kev tsim khoom machinery chaw kev lag luam, screws yog cov fasteners tseem ceeb uas txuas ntau yam tshuab tshuab; Nyob rau hauv kev lag luam automotive, screws yog siv los sib dhos ua ntau yam ntawm lub tsheb. Nrog kev nce qib ntawm science thiab thev naus laus zis thiab kev txhim kho kev lag luam, kev ua haujlwm thiab cov ntaub ntawv ntawm cov ntsia hlau yuav txuas ntxiv txhim kho cov khoom siv ntau ntxiv thiab kev siv ntau yam.
