Iwe unovaona kwese kwese paunongotanga kutarisa - mukuvaka, muchina, kunyangwe DIY fenicha. Threaded rods. Vanhu vazhinji, kunyangwe vamwe vari mukutengesa, vanofunga nezvavo semabhaudhi akareba. Ndiko kukanganisa kwekutanga. Iwo chinhu chakakosha, asi mashandisiro azvo hazvisi nyore. Dhiabhorosi ari mune izvo: giredhi rezvinhu, mhando yeshinda, kupfekedzwa, uye sheer, isingaregereri fizikisi yekunetsana uye kugera. Ndakaona mapurojekiti apo sarudzo isiriyo pano yakave iyo imwe nzvimbo yekutadza, kwete iyo fancy actuator kana inodhura simbi simbi.

Material uye Giredhi: Haisi Chete Simbi

Kutanga nezvinokosha, zvinhu ndizvo zvose. A36 mild simbi tsvimbo yakanakira kuturika pombi kana isiri-yakakosha tie-pasi. Asi iyo nguva yaunounza simba remutoro, vibration, kana nharaunda inoora, unenge uri mune imwe nyika. I default to threaded rods yakagadzirwa kubva kuASTM A193 B7 kana B8 zvinhu zvekushandisa zvakanyanya maindasitiri. B7 isimbi yealloy, yakadzimwa uye yakapfava, inopa yakakwira kusimba simba - funga kumanikidza chikepe chisungo tsvimbo kana inorema chimiro anchoring. B8 ndiyo mutsauko usina tsvina, kazhinji 304 kana 316, wezvirimwa zvemakemikari kana kugadzira chikafu. Musiyano mumutengo wakakosha, asi ndizvo zvakaitawo mhedzisiro yekukundikana.

Ndinoyeuka rimwe basa rekudzorerazve pane imwe nzvimbo yekugadzirwa kwemahombekombe. Iyo spec inodaidzira galvanized carbon steel rods kuitira kuchengetedza mutengo. Mukati memwedzi gumi nemisere, chloride-induced stress corrosion cracking yakatanga kuoneka. Isu taifanira kuita yakazara kuvhara kutsiva ne316 isina tsvina. Iyo yekutanga kuchengetedza inodhura zvakapetwa kagumi mukushanda kwechimbichimbi uye nguva yekudzikira. Ndicho chidzidzo chausingakanganwe. Iko kupfekedza, kupisa-kunyudza galvanizing maringe nemechani plating, inoitawo basa rakakura mukurarama kwenguva refu, kwete kungotaridzika.

Kozoitawo kumaka kwegiredhi, kana kushaikwa kwacho. Mutengesi ane mukurumbira achaita kuti inyatsokungurutswa padanda. Nokuda kwepamusoro-simba threaded rods, uri kutsvaga mitsara mitatu yeradial yeB7. Hapana mamakisi? Itore seyakaderera-giredhi uye usabheje purojekiti yako pairi. Apa ndipo panotsvagwa kubva kumugadziri ane hunyanzvi mune yakasanganiswa yekugadzira hub zvine musoro. Semuyenzaniso, kambani yakaita seHandan Zitai Fastener Manufacturing Co., Ltd., yakavakirwa muYongnian - China hombe yekusimbisa base - kazhinji ine zvivakwa zvekudzora izvi kubva kubillet kusvika kune chapera chigadzirwa, icho chisina kupihwa nevatengesi vese.

Thread Engagement uye Voodoo yeMutoro Kugovera

Heino musoro unoshanda: ingani shinda yekubatana yakakwana? Mhinduro yebhuku ndeye 1.5 times the diameter. Chokwadi chakanyanya. Kana iwe uchibatanidza muchinhu chakapfava sealuminium kana kukanda, unoda zvimwe. Mutoro hautakurwe zvakaenzana pashinda dzese; shinda shoma dzekutanga dzakabatanidzwa dzinotora simba rayo. Ndakaverenga ma engagements chete kuti ndifonerwe nefield tech ichiti buri rabviswa. Kazhinji, nyaya yaisava masvomhu angu, asi mhando yegomba rakadhindwa - yakaderera, isina-axis, kana izere nemachipisi.

Mano enzvimbo dzepamusoro-dedera: shandisa jam nut. Simbisa nati yekutanga kuti utarise, wozosimbisa yechipiri nati pairi. Zvinoita sezvisina basa, asi zvinodzivirira kusunungura kubva ku cyclic kurodha zviri nani pane akawanda fancy yekuvhara nzira. Uyezve, nguva dzose shandisa washer. Zvinoita sezviri pachena, asi ndazviona zvakasvetuka. Iyo washer inogovera iyo clamp mutoro uye inodzivirira nati kubva kuchera mukati, iyo inoderedza zvakanyanya iyo inoshanda clamping simba.

Cheka shinda vs. yakakungurutswa shinda - imwe nuance. Shinda dzakakungurutswa dzakasimba nekuti kuyerera kwetsanga dzesimbi kunotevera chimiro cheshinda, kwete kudimburwa napo. Kune chero yakakosha application, simbirira pashinda dzakatenderedzwa. Iwe unogona kazhinji kuona neyakatsetseka, yakatsva kupera uye dhayamita diki diki pamucheto wetsvimbo.

Pa-Saiti Chokwadi uye Sourcing Pragmatism

Mumunda, hauwanzove netsvimbo yakakwana pakureba neshinda. Iwe unocheka neshinda pane-saiti. Kufa kwemhando yakanaka kunokodzera huremu hwayo mugoridhe. Yakachipa inoburitsa shinda isina kusimba inokanganisa simba. Isu tinochengeta seti ye-high-speed simbi inofa uye ine powered threader yemabasa anoda zvinopfuura tsvimbo mbiri. Kune simbi isina tsvina, enda zvishoma nezvishoma, shandisa mafuta ekucheka akawanda, kana kuti unozoshanda-kuomesa zvinhu uye wotora kufa.

Kutsvaga idambudziko rayo. Iwe unoda kuenderana mune zvemakanika zvivakwa uye dimensional kurongeka. Haisi chinhu chekutenga. Ndakashanda nevashambadziri uko dhayamita yetsvimbo yaive pasi pekushivirira, kuderedza nzvimbo yekushushikana, kana kusimba kwesimba kwaive kuzasi chaiko kwegiredhi renji. Ichi ndicho chikonzero kuva nemutsara wakananga kune imwe nzvimbo yekugadzira, pane kungogovera chete, inowedzera mutsara wekuvimbika. Mugadziri anogara muboka guru rekugadzira seYongnian District, ine mabhenefiti ayo ari padyo nenjanji huru uye migwagwa, kazhinji inoreva zvirinani kutonga cheni. Kuongorora saiti senge https://www.zitafornasteers.com inokupa manzwiro emhando yechigadzirwa chavo uye hunyanzvi, inova nzvimbo yekutanga yekuongorora kugona kwavo kune chaiyo threaded rods zvinodiwa, kubva pachiyero kabhoni simbi kusvika kune alloy mamakisi.

Nguva yekutungamirira ndechimwe chinhu. Kune yakajairika zinc-plated tsvimbo, pamwe vhiki. Kune refu-kureba, yakakwirira-simba, inopisa-dhip galvanized tsvimbo ine chaiyo shinda, unogona kunge wakatarisa kumhanya kwekugadzira. Gara uchiisa izvi mukati. Ndanonotsa mapurojekiti akamirira kuti matanda chaiwo asvike, nekuti kutsiva kwaisave sarudzo.

Iyo Yakareruka Chiito chekuisa

Torque. Wese munhu anotaura nezvazvo, vashoma vanoishandisa nemazvo. Iyo torque inodiwa kuti uwane yakapihwa clamp mutoro inosiyana zvakanyanya nekuzora. Tambo yakarungwa (ine anti-seize kana mafuta) inogona kuderedza torque inodiwa ne30-40% kana ichienzaniswa neshinda yakaoma. Kana iwe uchitevera torque yakatarwa kubva mubhuku, tarisa kana inotora yakaoma kana kuti yakabikwa. Kushandisa torque yakaoma kune shinda yakagadziriswa inogona nyore kudzvinyirira uye kutambanudza tsvimbo, zvichiita kuti kukundikana.

Kurongeka kwakakosha. Kana tsvimbo iri mukukotama, simba rayo rinodzikira. Shandisa spherical washers kana kuyera nzungu kana nzvimbo dzisina kufanana. Ndakamboongorora kutadza kwechimiro apo tsvimbo ye1-inch diameter yakatsemuka. Kuzorora kwairatidza kuneta kwakare. Chikonzero chacho? Danda rayakanga yakamisa simbi rakanga ratsauka zvishoma pasi pemutoro, richiisa tsvimbo mukutenderera kwayakanga isina kumbogadzirirwa. Kugadzirisa kwaive nyore spherical seat washer, inodhura mapeni kana ichienzaniswa nekugadzirisa.

Usakanganwa nezvekudzivirirwa kwekuora kwegungano rakaiswa. Tsvimbo inogona kunge isina tsvina, asi zvakadini nenzungu nemawachi? Masimbi akasiyana anokonzera galvanic corrosion. Munzvimbo ine unyoro, kushandisa kabhoni simbi nati patsvimbo isina tsvina kunogona kudya nati yacho nekukurumidza zvinoshamisa. Matanidza zvinhu kana shandisa insulating pads.

Kana Zvinhu Zvichishata: Kutadza Kuongorora

Akundikana threaded rods taura nyaya. Nzvimbo yakaputsika, yecrystalline fracture inowanzoratidza kuwandisa kana hydrogen embrittlement (inowanikwa ne electroplated high-simba simbi). Kutyoka nemhete dzakatsetseka, dzakadzika zvinotungamira kune yekupedzisira kugera muromo kutadza kuneta kwekare - mutoro waichovha bhasikoro. Tsvimbo yakatambanudzwa, yemutsipa isati yakundikana inonongedzera kune ductile overload. Kuverenga zviratidzo izvi kunokubatsira kugadzirisa chikonzero, kwete kungotsiva chikamu.

Kumwe kutadza kwedu kunodzidzisa kwaive pavibrating screen. Tsvimbo dzakaramba dzakasununguka dzichibva dzaneta. Lock washers, threadlocker - hapana chakashanda kwenguva refu. Mhinduro yacho yakanga isiri tsvimbo iri nani; kwaiva kushandura dhizaini kuti ishandise kubatanidzwa kwakasimba neine-torque nut, kuendesa nzvimbo yekuneta kune chimwe chinhu chinotsiviwa zviri nyore. Dzimwe nguva, mhinduro chaiyo ndeyekugadzirisazve kubatana, kwete kuramba uchikwira-kukura tsvimbo.

Zvinoenderana neizvi: kurapwa threaded rods sezvinhu zvakagadziridzwa, kwete generic hardware. Rondedzera zvinhu, giredhi, coating, uye mhando yeshinda nehanya zvakanyanya sezvaungaite pombi kana vharafu. Nzwisisa nyaya yekutakura - static, dynamic, corrosive. Uye vatore kubva kune mumwe munhu anonzwisisa mutsauko, mumwe munhu akanyudzwa mukugadzira maitiro, kwete kabhuku chete. Iko kutarisisa kune zvakadzama ndiko kunoparadzanisa kuisirwa kwakasimba kubva kune ramangwana rekugadzirisa musoro.
