Kev piav qhia ntau lawm
Anti loosening txiv ntseej thiab tus kheej zawm ceev yog hom fastening anti loosening ceev. Xws li txhua yam los tiv thaiv loosening, riveting anti loosening, kev sib txhuam los tiv thaiv loosening, structural anti loosening, thiab lwm yam.
Peb qhov zoo ntawm kev tiv thaiv loosening ceev:
Ua ntej, kev ua haujlwm zoo tshaj plaws los tiv thaiv kev vibration: Thaum cov xov yog nruj, cov xov xov xov nyob rau sab saum toj ntawm lub ntsia liaj qhov rooj nruj nreem nkag mus rau 30 ° wedge-shaped txoj kab nqes ntawm cov txiv ntseej thiab yog clamped, thiab lub zog ib txwm tsim los ntawm cov npoo-puab txoj kab nqes. tsim lub kaum sab xis 60 ° nrog lub axis ntawm lub ntsia liaj qhov rooj, tsis yog lub kaum sab xis 30 °. Yog li ntawd, lub zog ib txwm tsim tawm thaum zawm cov txiv ntoo los tiv thaiv loosening ntau dua li cov txiv ntoo zoo tib yam, uas muaj peev xwm tiv thaiv kev xoob thiab tiv thaiv kev co.
Qhov thib ob, nws muaj zog hnav tsis kam thiab shear tsis kam: 30 ° txoj kab nqes ntawm hauv qab ntawm cov txiv ntoo xov tuaj yeem faib qhov sib npaug ntawm cov txiv ntoo ntawm txhua txoj xov. Vim tias qhov sib txawv ntawm cov clamping quab yuam ntawm txhua qhov xov, cov txiv ntoo tuaj yeem daws cov teeb meem ntawm xov hnav thiab shear deformation.
Thib peb, kev rov siv tau zoo: kev siv dav siv tau pom tias lub zog kaw ntawm cov txiv ntoo los tiv thaiv cov txiv ntoo tseem tsis hloov pauv tom qab rov ua kom nruj thiab tshem tawm, thiab cov txiaj ntsig tseem ceeb tuaj yeem khaws cia.
