Seismic deformed steel bar
Lus piav qhia luv luv:
Xov yog hais txog cov kauv zoo li tus nruam convex ib feem nrog rau ntu tshwj xeeb ua rau saum npoo ntawm cylindrical lossis conical niam txiv lub cev.Cov xov yog muab faib ua cylindrical threads thiab conical threads raws li lawv niam txiv duab;Nws tuaj yeem muab faib ua cov xov sab nraud thiab cov xov sab hauv raws li nws txoj haujlwm hauv niam txiv lub cev, thiab tuaj yeem muab faib ua cov xov peb sab, cov xov xwm plaub, xov trapezoidal, serrated xov thiab lwm cov xov tshwj xeeb raws li nws cov duab seem (cov hniav zoo nkauj).
Kev faib ua qauv
xov
Cov xov tau muab faib ua cov duab peb sab, cov duab plaub, cov xov trapezoidal thiab serrated threads raws li lawv cov duab seem (cov hniav profile).Daim duab peb sab threads yog siv rau kev sib txuas (saib xov txuas), thiab cov duab plaub, trapezoidal thiab serrated threads yog siv rau kev sib kis.Threads faib rau sab nrauv ntawm matrix yog hu ua lwm threads, thiab cov nyob rau hauv lub puab nto ntawm lub matrix yog hu ua internal threads.Cov xov tsim ntawm lub cylindrical matrix yog hu ua cylindrical xov, thiab cov xov tsim ntawm lub conical matrix hu ua conical thread.Cov xov tau muab faib ua cov xov sab laug thiab sab xis raws li cov lus qhia helix.Feem ntau, txoj cai xov yog siv.Cov xov tuaj yeem muab faib ua ib kab thiab ntau kab, thiab feem ntau ntawm cov xov siv rau kev sib txuas yog ib kab;Thaum siv rau kev sib kis, nws yuav tsum tau nqa ceev ceev lossis ua haujlwm siab.Ob kab lossis ntau kab tau txais, tab sis feem ntau tsis pub ntau tshaj 4 kab.
Xov kev taw qhia
Daim duab peb sab threads yog siv rau kev sib txuas, thaum lub duab plaub, trapezoidal thiab serrated threads yog siv rau kev sib kis;Raws li cov kev taw qhia helix, nws tau muab faib ua cov xov sab laug thiab txoj cai xov, feem ntau txoj xov sab xis;Raws li tus naj npawb ntawm helix, nws tuaj yeem muab faib ua ib leeg xov, ob txoj xov thiab ntau xov xov;Kev sib txuas feem ntau yog ib qho xaim, thiab kev sib kis yog ob lub xaim lossis ntau cov xaim;Raws li qhov loj ntawm cov hniav, nws tuaj yeem muab faib ua cov xov ntxhib thiab cov xov zoo.Raws li cov sijhawm sib txawv thiab kev ua haujlwm, nws tuaj yeem muab faib ua cov xov fastening, yeeb nkab xov, kis xov, xov tshwj xeeb, thiab lwm yam.
Nyob rau hauv cylindrical xov, daim duab peb sab xov muaj kev ua haujlwm zoo ntawm tus kheej.Nws muab faib ua cov hniav ntxhib thiab cov hniav zoo.Feem ntau, coarse threads yog siv rau kev sib txuas.Cov hniav zoo muaj qhov me me, me me nce lub kaum ntse ntse thiab zoo dua qhov kev ntsuas tus kheej.Lawv feem ntau siv nyob rau hauv me me, nyias-walled hlab, kev co los yog variable load kev twb kev txuas thiab zoo-tuning pab kiag li lawm.Cov yeeb nkab xov yog siv rau kev sib txuas nruj ntawm cov yeeb nkab fittings.Rectangular xov muaj kev ua haujlwm siab, tab sis nws feem ntau hloov los ntawm cov xov trapezoidal vim nws tsis yooj yim rau zom thiab nws nyuaj rau ntsia hlau rau hauv thiab nruab nrab ntawm cov xov sab hauv thiab sab nraud.Lub ntug ua hauj lwm ntawm serrated xov yog nyob ze rau lub duab plaub ncaj ntug, uas feem ntau yog siv los dais unidirectional axial quab yuam.
Cov hniav daim ntawv ntawm conical xov yog daim duab peb sab, uas feem ntau yog nyob ntawm qhov deformation ntawm cov hniav kom ntseeg tau qhov nruj ntawm cov xov khub.Nws feem ntau yog siv rau cov yeeb nkab fittings.
Raws li qhov nruj, nws tuaj yeem muab faib ua cov xov kaw thiab tsis kaw xov.
