Ntsia Hlau Qauv
Cov ntsia hlau yog ib qho fastener uas muaj ntau yam. Feem ntau, cov ntsia hlau tus qauv suav nrog cov ntsia hlau ncej, txiv ntseej, ntxhua khaub ncaws, thiab tuav lub nplhaib. Hauv qab no, peb yuav qhia txog cov haujlwm thiab cov yam ntxwv ntawm txhua ntu.
Ntsia Hlau Ncej
Lub taub hau ntsia hlau yog lub cev tseem ceeb ntawm cov ntsia hlau thiab ib qho tseem ceeb ntawm cov fastener. Nws feem ntau yog ua los ntawm cov khoom siv hlau xws li steel lossis tooj liab, muaj qee qhov kev nyuaj thiab corrosion kuj. Lub luag haujlwm ntawm cov ntsia hlau ncej yog tig thiab nkag mus rau hauv cov khoom kom ruaj khov, txhim kho cov khoom ua ke los ntawm kev sib txhuam thiab tensile quab yuam.
Txiv ntseej
Cov txiv ntseej yog ib qho fastener uas phim cov ntsia hlau ncej. Feem ntau, cov txiv ntoo yog ua los ntawm cov khoom siv tib yam li cov ntsia hlau ntsia hlau. Lub luag haujlwm ntawm cov txiv ntoo yog kho, zawm, thiab xa cov kev kho lub zog ntawm cov ntsia hlau ncej, ua rau nws yog ib qho tseem ceeb ntawm cov txheej txheem ntsia hlau.
Lub tshuab ntxhua khaub ncaws
Lub tshuab ntxhua khaub ncaws yog ib qho chaw nyob nruab nrab ntawm cov txiv ntoo thiab cov khoom yuav tsum tau fastened. Feem ntau, lub tshuab ntxhua khaub ncaws yog ua los ntawm cov khoom siv tib yam li cov ntsia hlau ncej thiab cov txiv ntoo, tab sis nws kuj tuaj yeem ua los ntawm cov yas. The function of the washer is to increase the tightening area, distribute pressure, prevent the nut from exerting excessive pressure on the material to be fastened, thereby reducing damage to the material surface.
Snap nplhaib
Lub nplhaib snap yog cov khoom siv elastic feem ntau siv los kho txoj haujlwm ntawm cov txiv ntoo lossis tiv thaiv nws los ntawm kev xoob. Snap rings feem ntau yog ua los ntawm cov hlau elastic, uas muaj kev tiv thaiv zoo heev thiab elasticity. Lub luag haujlwm ntawm lub nplhaib snap yog tsim kom muaj elastic deformation ntawm cov ntsia hlau thiab cov txiv ntoo, ua kom lub zog loosening thiab kho cov txiv ntoo hauv nws txoj haujlwm nruj, yog li tiv thaiv nws los ntawm loosening.
