Intshayelelo yeMveliso

Xa kuthelekiswa nentsimbi eqinileyo njengentsimbi ejikelezileyo, umbhobho wentsimbi unobunzima bobunzima xa ukugoba kunye namandla e-torsion afanayo.Yintsimbi enqamlezileyo yezoqoqosho kwaye isetyenziswa ngokubanzi ukwenza iinxalenye zesakhiwo kunye neengxenye zemishini, ezifana nombhobho we-oyile wokugaya, i-shaft yokuhambisa i-automobile, isakhelo sebhayisikili kunye ne-scaffold yensimbi esetyenziselwa ukwakha.Ukuvelisa iinxalenye ezimise okwesangqa ngemibhobho yentsimbi kunokuphucula izinga lokusetyenziswa kwezinto, ukwenza lula inkqubo yokuvelisa, kunye nokugcina izixhobo kunye neeyure zokusebenza, ezifana nokuqengqeleka amakhonkco okuthwala kunye nemikhono yeJack.Okwangoku, iibhobho zentsimbi zisetyenziswe ngokubanzi kwimveliso.Umbhobho wentsimbi ukwayinto eyimfuneko kuzo zonke iintlobo zezixhobo eziqhelekileyo.Umgqomo kunye nombhobho wezibhamu zenziwe ngombhobho wensimbi.Imibhobho yentsimbi inokwahlulwa ibe yimibhobho engqukuva kunye nemibhobho ekhethekileyo ngokweendawo ezahlukeneyo ezinqamlezileyo kunye nemilo.Ekubeni ummandla wesetyhula ngowona mkhulu phantsi kwemeko yokulinganisa okulinganayo, amanzi amaninzi anokuhanjiswa ngemibhobho ejikelezayo.Ukongezelela, xa icandelo lendandatho liphantsi koxinzelelo lwangaphakathi okanye lwangaphandle lwe-radial, i-force ifana kakhulu.Ngoko ke, uninzi lwemibhobho yentsimbi yimibhobho ejikelezayo.

Umgangatho: GB/T8163.

IBanga leMbhobho yeNsimbi ePhambili: 10, 20, Q345, njl.

Amanye amabakala anokunikezelwa emva kokubonisana nabathengi.

Inkqubo yeTekhnoloji

Ukuqengqeleka okushushu (umbhobho wentsimbi ongenamthungo okhutshiweyo): ityhubhu engqukuva ingenanto → ukufudumeza → ukugqobhoza → ukuqengqeleka okuthathu okuqengqelekayo, ukuqengqeleka okuqhubekayo okanye ukukhutshwa kombhobho → ukucolwa kombhobho → ukwenza ubungakanani (okanye ukunciphisa) → ukupholisa → ityhubhu engenanto → ukolula → uvavanyo lwe-hydrostatic (okanye ukubonwa kwesiphako) → ukuphawula → ugcino.

Umbhobho wentsimbi obandayo ozotyiweyo (oqengqiwe): umbhobho wetyhubhu engqukuva → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukugqunywa kweoyile (iplate yobhedu) → imizobo emininzi ebandayo (ukuqengqeleka okubandayo) → ibhilethi → unyango lobushushu → ukulungisa → uvavanyo lwe-hydrostatic (isiphene ubhaqo) → ukuphawula → ugcino.
