Yiziphi izilinganiso ze-ANSI, ISO, NE-ASTM zamabheringi?

Izindinganiso zobuchwepheshe, njengezindinganiso ze-ASTM zamabheringi acacisa ukuthi iyiphi iresiphi yensimbi okufanele isetshenziswe, asiza abakhiqizi ukwenza umkhiqizo ongashintshi.

 

Uma useshe ama-bearings ku-inthanethi, kungenzeka uhlangabezane nezincazelo zomkhiqizo mayelana nokuhlangabezana namazinga e-ANSI, ISO, noma ASTM.Uyazi ukuthi amazinga awuphawu lwekhwalithi - kodwa ngubani oqhamuke nawo, futhi asho ukuthini?

 

Izindinganiso zobuchwepheshe zisiza kokubili abakhiqizi nabathengi.Abakhiqizi bawasebenzisela ukwenza nokuhlola izinto kanye nemikhiqizo ngendlela engaguquki kakhulu.Abathengi bawasebenzisa ukuze baqinisekise ukuthi bathola ikhwalithi, ukucaciswa, nokusebenza abakucelile.

 

AMAZINGA ANSI

I-American National Standards Institute, noma i-ANSI, izinze eWashington, DC.Amalungu ayo ahlanganisa izinhlangano zamazwe ngamazwe, izinhlangano zikahulumeni, izinhlangano, nabantu ngabanye.Yasungulwa ngo-1918 njengeKomiti Yezinga Lobunjiniyela BaseMelika lapho amalungu e-United Engineering Society kanye neminyango kahulumeni wase-US Yezempi, Yezempi, Nezohwebo behlangana ndawonye ukuze bakhe inhlangano yamazinga.

I-ANSI ayidali izindinganiso zobuchwepheshe ngokwayo.Kunalokho, yengamela amazinga aseMelika futhi iwaxhumanise namazwe ngamazwe.Igunyaza izindinganiso zezinye izinhlangano, iqinisekisa ukuthi wonke umuntu embonini uyavumelana ngokuthi izinga liyithinta kanjani imikhiqizo nezinqubo zabo.I-ANSI ivumela kuphela amazinga ebona kufanelekile futhi avuleke ngokwanele.

I-ANSI yasiza ekutholeni i-International Organisation for Standardization (ISO).Ungomele i-ISO esemthethweni yase-United States yase-United States.

I-ANSI inamazinga amaningana ahlobene namabhola.

 

AMAZINGA E-ISO

I-International Standards Organisation (ISO) eseSwitzerland ichaza izindinganiso zayo ngokuthi “ifomula echaza indlela engcono kakhulu yokwenza okuthile.”I-ISO yinhlangano yamazwe ngamazwe ezimele, engekho ngaphansi kukahulumeni eyakha amazinga omhlaba.Izinhlangano zamazinga kazwelonke eziyi-167, njenge-ANSI, zingamalungu e-ISO.I-ISO yasungulwa ngo-1947, ngemva kokuba izithunywa ezivela emazweni angu-25 zihlangene ukuze zihlele ikusasa lokumiswa kwamazwe ngamazwe.Ngo-1951, i-ISO yakha izinga layo lokuqala, i-ISO/R 1:1951, elanquma izinga lokushisa eliyinkomba lezilinganiso zobude bezimboni.Kusukela lapho, i-ISO idale cishe amazinga angama-25,000 kuyo yonke inqubo ongayicabanga, ubuchwepheshe, isevisi, kanye nezimboni.Izindinganiso zayo zisiza amabhizinisi akhulise ikhwalithi, ukusimama, nokuphepha kwemikhiqizo yawo nezinqubo zokusebenza.Kukhona ngisho nendlela ejwayelekile ye-ISO yokwenza inkomishi yetiye!

I-ISO inamazinga acishe abe ngu-200.Amakhulu amanye amazinga ayo (njengalawo amayelana nensimbi ne-ceramic) athinta ama-bearings ngokungaqondile.

 

AMAZINGA E-ASTM

I-ASTM imele i-American Society for Testing and Materials, kodwa inhlangano ezinze ePennsylvania manje isiyi-ASTM International.Ichaza izindinganiso zobuchwepheshe zamazwe emhlabeni jikelele.

I-ASTM inezimpande zayo kojantshi beNguquko Yezimboni.Ukungahambisani kojantshi bensimbi kwenza ukuba amathrekhi esitimela aphuke.Ngo-1898, usokhemisi uCharles Benjamin Dudley wasungula i-ASTM neqembu lonjiniyela nososayensi ukuze bathole isisombululo sale nkinga eyingozi.Bakha isethi ejwayelekile yezincazelo zensimbi yomzila wesitimela.Eminyakeni eyi-125 selokhu yasungulwa, i-ASTM ichaze amazinga angaphezu kwe-12,500 ngenani elikhulu lemikhiqizo, izinto zokwakha, nezinqubo ezimbonini ezisukela kwezimbiwa ezingavuthiwe nophethiloli kuya emikhiqizweni yabathengi.

Noma ubani angajoyina i-ASTM, kusukela kumalungu emboni kuya kwezifundiswa nabeluleki.I-ASTM idala izindinganiso zokuvumelana ngokuzithandela.Amalungu afinyelela esivumelwaneni esiyiqoqo (ukuvumelana) mayelana nokuthi izinga kufanele libe yini.Amazinga ayatholakala ukuze noma yimuphi umuntu noma ibhizinisi liwathathe (ngokuzithandela) ukuze liqondise izinqumo zalo.

I-ASTM inamazinga angaphezu kwe-150 ahlobene namabhola namaphepha ochungechunge.

 

I-ANSI, ISO, NAMAZINGA E-ASTM AKUSIZA UTHENGE AMABHERE AMAHLE

Izindinganiso zobuchwepheshe ziqinisekisa ukuthi wena nomkhiqizi ophethe nikhuluma ulimi olufanayo.Uma ufunda ukuthi i-bearing yenziwe ngensimbi ye-chrome ye-SAE 52100, ungabheka izinga le-ASTM A295 ukuze uthole ukuthi insimbi yenziwe kanjani nokuthi yiziphi izithako eziqukethe.Uma umkhiqizi ethi ama-roller bearings akhe acijile angubukhulu obucaciswe yi-ISO 355:2019, wazi kahle ukuthi uzowuthola muphi usayizi.Nakuba izindinganiso zobuchwepheshe zingaba ngokwedlulele, kahle, ubuchwepheshe, ziyithuluzi elibalulekile lokuxhumana nabahlinzeki bempahla nokuqonda ikhwalithi nokucaciswa kwezingxenye ozithengayo.Ulwazi olwengeziwe, Sicela uvakashele iwebhu yethu: www.cwlbearing.com
