Cov txiv ntseej yog cov xov txuas, feem ntau yog siv nrog bolts lossis screws, kom ruaj ntseg txuas ob lossis ntau qhov chaw ua ke los ntawm kev sib koom ua ke. Nws yog ib qho tseem ceeb ntawm cov khoom tseem ceeb hauv mechanical engineering.
Cov yam ntxwv tseem ceeb ntawm cov txiv ntoo muaj xws li:
Nws muaj lub hauv paus ncig lub qhov nrog threads machined hauv. Nws tsuas tuaj yeem ntsia tau rau hauv bolts lossis screws ntawm tib qhov tshwj xeeb; Piv txwv li, M6 txiv ntseej tsuas yog siv tau nrog M6 ntsia liaj qhov rooj.
Cov duab zoo ib yam yog hexagonal (rau yooj yim zawm nrog ib tug ciaj ntswj), tab sis kuj muaj cov qauv tshwj xeeb xws li puag ncig, square, thiab flanged hom.
Nws yog tsim los ntawm ntau yam ntaub ntawv, suav nrog carbon steel, stainless hlau, thiab tooj liab alloys, haum rau ntau qhov chaw thiab lub zog yuav tsum tau ua.
Hauv kev lag luam, nws yog lub npe hu ua "mov ntawm kev lag luam," dav siv hauv tsheb, kev tsim kho, electronics, aerospace, thiab lwm yam.
Tsis tas li ntawd, raws li kev ua haujlwm thiab cov qauv, cov txiv ntoo tuaj yeem muab faib ua ntau hom, xws li:
Hexagonal txiv ntseej: Hom ntau tshaj plaws, muaj ntau yam.
Flanged txiv ntseej: nta ib qho ua tau - nyob rau hauv lub tshuab ntxhua khaub ncaws kom faib cov siab thiab tiv thaiv kom xoob.
Locknut: Muab kev tiv thaiv -loosing muaj nuj nqi thiab tsim nyog rau kev co ib puag ncig.
Cov txiv ntseej square: Lawv muaj square cross-section, zoo tiv thaiv- kev sib hloov ua haujlwm, thiab feem ntau yog siv rau cov ntawv hlau sib txuas.
