Chii chinonzi ANSI, ISO, uye ASTM zviyero zvemabheya?

Tekinoroji zviyero, seASTM zviyero zvemabheri izvo zvinotsanangura kuti ndeipi resipi yekushandisa, inobatsira vagadziri kugadzira chigadzirwa chakafanana.

 

Kana iwe wakatsvaga mabearings pamhepo, ungangove wakasangana nerondedzero yechigadzirwa nezvekusangana neANSI, ISO, kana ASTM zviyero.Iwe unoziva kuti zviyero chiratidzo chemhando - asi ndiani akauya nazvo, uye zvinorevei?

 

Miyero yehunyanzvi inobatsira vese vagadziri nevatengi.Vagadziri vanoashandisa kugadzira uye kuyedza zvinhu uye zvigadzirwa nenzira inowirirana inogoneka.Vatengi vanozvishandisa kuona kuti vari kuwana mhando, mataurirwo, uye kuita kwavakakumbira.

 

ANSI MITIRO

IAmerican National Standards Institute, kana ANSI, ine muzinda muWashington, DC.Nhengo dzayo dzinosanganisira masangano epasi rose, masangano ehurumende, masangano, uye vanhuwo zvavo.Yakavambwa muna 1918 seAmerican Engineering Standards Committee apo nhengo dzeUnited Engineering Society nehurumende yeUS Dhipatimendi reHondo, Navy, uye Commerce vakaungana kuti vaumbe sangano rezviyero.

ANSI haigadziri tekinoroji zviyero pachayo.Pane kudaro, inotarisira zviyero zveAmerica uye inozvibatanidza nevepasi rose.Inobvumidza mwero wemamwe masangano, kuve nechokwadi chekuti munhu wese muindasitiri anobvumirana kuti chiyero chinokanganisa sei zvigadzirwa nemaitirwo avo.ANSI inongobvumira mazinga ayo aanoona akakodzera uye akavhurika zvakakwana.

ANSI yakabatsira kuwana International Organisation for Standardization (ISO).Mumiriri weISO weUnited States weUnited States.

ANSI ine mazana akati wandei anotakura bhora zvinoenderana zviyero.

 

ISO ZVINHU

Switzerland-based International Standards Organisation (ISO) inotsanangura mwero wayo se "nzira inotsanangura nzira yakanaka yekuita chimwe chinhu."ISO isangano rakazvimirira, risiri rehurumende repasi rose rinogadzira mwero wepasi rose.167 masangano epasi rose, seANSI, inhengo dze ISO.ISO yakavambwa muna 1947, mushure mekunge nhumwa dzakabva kunyika makumi maviri neshanu dzaungana kuzoronga remangwana remamiriro ekunze.Muna 1951, ISO yakagadzira chiyero chayo chekutanga, ISO/R 1:1951, iyo yakatemera tembiricha yekuyera yehurefu hwemaindasitiri.Kubva ipapo, ISO yakagadzira zvingangosvika zviuru makumi maviri nezvishanu zviyero kune yega yega maitiro, tekinoroji, sevhisi, uye indasitiri.Miyero yaro inobatsira mabhizinesi kuwedzera kunaka, kusimba, uye kuchengetedzeka kwezvigadzirwa zvavo uye maitiro ebasa.Kune kana ISO yakajairwa nzira yekugadzira kapu yetii!

ISO ine angangoita mazana maviri ekubereka zviyero.Mazana ezvimwe zviyero zvayo (sezviya zvesimbi neceramic) zvinokanganisa mabhengi zvisina kunanga.

 

ASTM MITIRO

ASTM inomirira American Society for Testing and Materials, asi Pennsylvania-based organisation yava ASTM International.Inotsanangura zviyero zvehunyanzvi zvepasirese.

ASTM ine midzi yayo munjanji yeRevolution Revolution.Kusawirirana munjanji dzesimbi kwakaita kuti njanji dzechitima dzekutanga dzityoke.Muna 1898, chemist Charles Benjamin Dudley akaumba ASTM neboka remainjiniya nemasayendisiti kuti vawane mhinduro kudambudziko iri rine njodzi.Vakagadzira yakajairwa seti yezvakatemwa zvesimbi yenjanji.Kwemakore zana nemakumi maviri nemashanu kubva pakuvambwa kwayo, ASTM yakatsanangura zvinodarika zviuru gumi nezviviri nemazana mashanu zviyero zvehuwandu hukuru hwezvigadzirwa, zvigadzirwa, uye maitiro mumaindasitiri kubva kusimbi mbishi nepetroleum kune zvigadzirwa zvevatengi.

Chero ani zvake anogona kujoina ASTM, kubva kunhengo dzeindasitiri kuenda kuvadzidzi nevanopa mazano.ASTM inogadzira zviyero zvekubvumirana kwekuzvidira.Nhengo dzinouya kuchibvumirano chekubatana (kubvumirana) pamusoro pechipimo chinofanira kuva.Izvo zviyero zviripo kune chero munhu kana bhizinesi kutora (nekuzvidira) kutungamira zvisarudzo zvavo.

ASTM ine zvinodarika zana nemakumi mashanu zvine chekuita nebhora uye mapepa ehurukuro.

 

ANSI, ISO, UYE ASTM ZVINOKOSHA ZVINOBATSIRA IWE KUTENGA MABHARE AKANAKA

Matekinoroji ehunyanzvi anovimbisa kuti iwe nemugadziri anotakura munotaura mutauro wakafanana.Paunoverenga kuti simbi inogadzirwa kubva kuSAE 52100 chrome simbi, unogona kutarisa iyo ASTM A295 yakajairwa kuti uone chaizvo kuti simbi yacho yakagadzirwa sei uye kuti ine zvipi zvimisikidzo.Kana mugadziri akati tapered roller bearings ndiwo zviyero zvakatsanangurwa neISO 355:2019, iwe unonyatsoziva saizi yauchange uchiwana.Kunyangwe zviyero zvehunyanzvi zvinogona kuve zvakanyanyisa, zvakanaka, tekinoroji, chishandiso chakakosha chekutaurirana nevatengesi uye kunzwisisa mhando uye zvakatemwa zvezvikamu zvaunotenga.Ruzivo rwakawanda, Ndokumbira ushanyire webhusaiti yedu: www.cwlbearing.com
