M'dziko lazopanga ndi uinjiniya wamakina, kupanga zinthu kuti zigwirizane ndikofunikira. Ndipamene miyezo ya ulusi imayamba kugwira ntchito. Zili ngati malamulo a mmene mizere yozungulira pa bawuti imayenderana ndi mizere ya mtedza. Malamulowa ndi ofunikira kwambiri chifukwa amaonetsetsa kuti mbalizo zimagwira ntchito bwino, ndipo amatha kugwira ntchito yomwe akuyenera kuchita popanda kuswa.
Tiyeni tiyambe ndikumvetsetsa kuti ulusi wamba ndi chiyani. Mwachidule, ndiwo malangizo omwe amafotokoza mawonekedwe, kukula, ndi kulolerana kwa ulusi womwe umagwiritsidwa ntchito mu mabawuti, zomangira, ndi mtedza. Ganizirani za iwo ngati bukhu la maphikidwe opangira ulusi wogwirizana bwino. Miyezo iyi imawonetsetsa kuti bawuti yochokera kukampani ina ikwaniranati kuchokera ku ina, ndikusunga kusasinthika komanso kulondola m'mafakitale osiyanasiyana.
Miyezo ya ulusi imagwira ntchito yofunika kwambiri padziko lonse lapansi yopanga ndi uinjiniya wamakina . Ndiwo ngwazi zosadziwika mumsonkhano wa chirichonse kuchokera ku zipangizo zamagetsi pa bolodi la dera kupita kumagulu akuluakulu a ndege. M'mafakitale monga zopangira magalimoto oyendetsa ndege , zida , ngakhalenso ndege za m'mlengalenga , miyezo imeneyi imawonetsetsa kuti zonse zomangira , bolt ndi zomangira , ndi makina amakina amalumikizana bwino kwambiri komanso mwamphamvu . Izi ndizofunikira osati popanga kulumikizana kolimba komanso kusunga bata ndi chitetezo chazinthu.
Tsopano, tiyeni titenge ulendo wofulumira kupita ku mbiri yakale. The Unified Thread Standard (UTS) idayamba kugwiritsidwa ntchito ngati njira yochepetsera ndikuyimitsa ulusi wa screw ku United States ndi Canada. Pamaso pa UTS, panali miyezo yambiri ya ulusi, yomwe inali yosokoneza. UTS idabweretsa aliyense patsamba limodzi ndi mitundu iwiri ikuluikulu: Unified National Coarse (UNC) ndi Unified National Fine (UNF).
l UNC Threads : Zodziwika bwino chifukwa cha mawu ake osalala , ulusiwu ndi wabwino kugwiritsa ntchito wamba. Ndizosavuta kupanga ndikuzigwira, zomwe zimawapangitsa kukhala chisankho chodziwika bwino m'mafakitale omwe amafunikira mayankho okhazikika omwe amatha kupirira kupsinjika kwakanthawi komanso kuthamanga kwa kasinthasintha..
l UNF Threads : Izi zili ndi mawu abwino , omwe amapereka mphamvu zambiri komanso zolondola . Amagwiritsidwa ntchito nthawi zambiri ngati zida zamlengalenga ndi zida zolondola , pomwe millimeter iliyonse imawerengera.
UNC ndi UNF ulusi wonse umagwera pansi pa Unified Screw Thread Series , yomwe ili ngati banja lalikulu la ulusi wa screw wopangidwa kuti uzigwira ntchito mogwirizana.
Kuti muwone m'maganizo, lingalirani Tchati cha Screw Thread . Tchatichi chimandandalitsa kukula ndi mitundu yonse ya ulusi pansi pa UTS, kuphatikiza ulusi Wophatikizana wa coarse pitch and Unified fine pitch threads . Ndi chida chopitira kwa mainjiniya ndi opanga kupanga kusankha koyenera kwa ulusi pazogwiritsa ntchito zawo.
M'mawu omveka, miyezo ya ulusi imakhala kumbuyo kwachinthu pafupifupi chilichonse chamakina. Mwachitsanzo, pazida zamagetsi , kulondola kwa ulusi wa UNF kumatsimikizira kulondola kwa zigawo. M'mapulogalamu okulirapo, monga magalimoto kapena ndege , ulusi wa UNC umathandizira kupanga zida zolimba za chassis ndi zida za injini..
Kumvetsetsa miyezo ya ulusi, makamaka kusiyana pakati pa UNF ndi UNC , ndikofunikira. Sikuti kungopanga zidutswa ziwiri kuti zigwirizane; ndi kuonetsetsa chitetezo , kudalirika , ndi bwino . Kaya ndi yolondola kwambiri ntchito muzamlengalenga kapena gulu lalikulu muukadaulo wamakina , ulusi woyenera - kaya UNF kapena UNC - ungapangitse kusiyana kwakukulu pakugwira ntchito ndi moyo wautali wa chinthu. Mwachidule, mfundo za ulusi monga UNF ndi UNC pansi pa Unified Thread Standard ndizofunikira pakupanga zinthu zodalirika komanso zotetezeka. Amawonetsetsa kuti chilichonse kuyambira pachiwopsezo chaching'ono kwambiri mu bolodi lozungulira mpaka yayikulu kwambiri bawuti mundege , ndi ntchitoyo, kupereka mphamvu , yolondola yofunikira komanso kukana komwe kumafunikira pamagwiritsidwe osiyanasiyana.
The Unified Thread Standard (UTS) ili ngati bukhu lamalamulo la ulusi wogwiritsidwa ntchito ku North America. Ndizomwe zimawonetsetsa kuti wononga kuchokera pamalo amodzi kulowa nati kuchokera kwina. Mulingo uwu ndiwofunikira kwambiri m'mafakitale monga apamlengalenga , opanga magalimoto , komanso pazida zamagetsi.
UTS ili ndi magawo atatu akulu:
1. Fomu ya Ulusi : Awa ndi mawonekedwe a ulusi. Ganizirani izi ngati chitsanzo pa bawuti kapena screw. Ndikofunikira chifukwa imasankha momwe magawo awiri angagwirizane.
2. Series : Izi ndi za mitundu yosiyanasiyana ya ulusi. Ku UTS, pali mindandanda iwiri yayikulu - Unified National Coarse (UNC) ndi Unified National Fine (UNF). Mndandanda wa coarse (UNC) uli ndi ulusi wochepera pa inchi, pomwe mndandanda wabwino (UNF) uli ndi zambiri. Kusiyanaku kumakhudza momwe kugwirizana kungakhalire kolimba komanso kolimba.
3. Makalasi Oyenera : Izi zili ngati mulingo wa snugness pakati pa ulusi. Ndi za momwe amathina kapena omasuka. Pali makalasi angapo, aliwonse oyenerera ntchito zosiyanasiyana.
Ku North America, UTS ili paliponse. Umu ndi momwe amagwiritsidwira ntchito:
l Njira Yopangira : Makampani amagwiritsa ntchito UTS kupanga zinthu zamitundu yonse. Kuchokera pamabwalo ang'onoang'ono ozungulira kupita ku zazikulu za injini za ndege zigawo .
l Zida Zolondola : M'zida ndi zida zomwe zimafunikira kulondola kwambiri , monga muzamlengalenga kapena zida za ndege , UTS imathandiza kupanga magawo omwe amalumikizana bwino.
l Umisiri Wamagalimoto ndi Makina : Magalimoto, magalimoto, ngakhale makina amafakitale amafunikira magawo omwe amakwanira bwino. UTS imapangitsa izi kuchitika, kaya ndi zigawo za injini , ya chassis , kapenanso thupi.
l Zida Zamagetsi : Pazida zazing'ono, UTS imagwiranso ntchito yayikulu. Imawonetsetsa kuti mabawuti ting'onoting'ono ndi zomangira muzinthu zamagetsi zimagwirizana bwino.
Tangoganizani kuti mukupanga loboti. Mufunika mabawuti ndi zomangira zomwe zingagwirizanitse molimba. Mutha kusankha ulusi woyenera wa UNC kapena UNF kutengera zomwe loboti ingachite. Kodi idzafunika kupirira kupsinjika kwakukulu ? Kapena ikufunika kulongosoka kwenikweni? UTS imakuwongolerani popanga zisankho izi.
UTS ili ngati chinenero chimene opanga onse ku North America amalankhula. Ndi kuwonetsetsa kuti zonse zikugwirizana bwino, kaya ndi wononga ting'onoting'ono ta foni yamakono kapena bawuti yayikulu mundege. Muyezo uwu umapangitsa zinthu kukhala zotetezeka, zamphamvu, komanso kugwira ntchito bwino.
Tiyeni tilowe mu UNF Threads , omwe amadziwika ndi Unified Fine Pitch . Ulusi uwu ndi akatswiri ojambula mwatsatanetsatane a dziko la ulusi. Ali ndi ulusi wambiri pa inchi kuposa ulusi wa UNC , zomwe zikutanthauza kuti ndiabwino komanso otalikirana kwambiri. Kapangidwe kabwino kameneka kameneka kameneka kameneka kameneka kamene kamakhala kongofuna kudzionetsera; zonse ndi zolondola.
UNF ulusi ndi njira yoyenera kusankha pazochitika zomwe kulondola kwakukulu ndi mphamvu ndizofunikira. Apa ndi pamene amawala:
l Zamlengalenga : Mundege ndi zakuthambo, gawo lililonse laling'ono limafunikira. UNF ulusi umagwiritsidwa ntchito pano kuti ukhale wolondola.
l Zida Zolondola : Ganizirani za zida zomwe zili mu labotale kapena zida zamankhwala. UNF ulusi umathandizira zida izi kukhala zolondola komanso zodalirika.
l Kupanga Magalimoto : M'magalimoto, makamaka m'magawo a injini ndi zida zamagetsi , ulusi wa UNF umapereka zomwe zimafunikira.
l Zida Zamagetsi : Ngakhale m'mabwalo ang'onoang'ono ozungulira , ulusi wa UNF ndi wofunikira kuti zonse zikhale zogwirizana.
Tikamalankhula za kukula kwa ulusi wa UNF, tikuyang'ana pa Screw Thread Chart . Tchatichi chimatchula miyeso yonse - m'mimba mwake, mamvekedwe, ndi kutalika. Kutalika kwa ulusi wa UNF kumatha kuchoka pating'ono kwambiri mpaka kukulirakulira, koma fungulo ndi phula labwino - ulusi wambiri mu inchi iliyonse ya screw.
M'dziko lazopanga zapamwamba, ulusi wa UNF uli ngati ma VIP. Amapereka:
l Mphamvu Yapamwamba : Chifukwa cha phula lawo labwino, amatha kuthana ndi katundu wambiri komanso nkhawa.
l Kulumikizana Kwambiri : Ulusi wambiri umatanthauza kugwira mwamphamvu. Izi ndizofunikira pazigawo zomwe siziyenera kumasuka, makamaka pakugwedezeka.
l Kulondola : Ndi ulusi wambiri, pali mwayi wochepa wosuntha kapena kusanja molakwika. Izi ndizofunikira pazida zolondola komanso zida zakuthambo.
Tangoganizani kuti mukusonkhanitsa ndege yaukadaulo wapamwamba kwambiri. Chiwalo chilichonse chimayenera kukwanira bwino. UNF ulusi umakuthandizani kuti muwononge gawo lililonse molondola, kuwonetsetsa kuti drone ndi yokhazikika komanso yodalirika.
