Amantongomane omgcini

Uva 'i-keeper nuts' kwaye abantu abaninzi bacinga nge-locknut elula, mhlawumbi uhlobo lokufaka inayiloni. Leyo yimbono yokuqala ephosakeleyo. Enyanisweni, umgcini we-nut oyinyaniso, ngokukodwa kwi-heavy-duty okanye kwi-vibration-prone applications, isilwanyana esahlukileyo. Akunjalo nje ngokuthintela ukukhulula; imalunga nokugcina umthwalo obambeleyo ochanekileyo, usebenze njengesitshixo esikwindawo ethile, okanye nokusebenza njengendawo yokumisa koomatshini. Ndibone uyilo oluninzi kakhulu apho i-nut esemgangathweni ichazwe 'njengomgcini,' kuphela ukuba indibano ingaphumeleli kuvavanyo lwendawo ngenxa yokuba injineli ayizange ithathele ingqalelo i-axial kunye ne-radial forces echaphazelekayo. Igama ngokwalo liphantse libe banzi kakhulu, ligquma yonke into ukusuka kwi-jam nut kwisiqu sevalve ukuya kwi-specialized nut enesikhonkwane secotter kwishafti ejikelezayo. I-nuance yinto yonke.

Umsebenzi ongundoqo kunye neMigibe eqhelekileyo

Makhe sicacise. Umsebenzi ophambili 'kukugcina' useto. Umzekelo, kunxibelelwano oluhlengahlengiswayo, useta ubude, emva koko uqinise i-nut yomgcini ngokuchasene ne-turnbuckle okanye isiphelo sentonga. Indawo yokungaphumeleli apha ihlala iphantsi kwe-torque. Abantu bayoyika imicu yokugalela okanye ukuguqula icandelo, ngoko bayakhanya. Isiphumo? Ukungcangcazela kuyenza ikhululeke ngaphezu kweeyure ezimbalwa. Ndifunde oku ngendlela enzima kwiprojekthi yenkqubo yokuhambisa. Sisebenzise i-hex nut eqhelekileyo njengomgcini kwintonga yoxinzelelo. Icacisa itorque ngokwetshati yegeneric. Kwiinyanga ezintathu kamva, savalwa ngenxa yokuba intonga yabuyela umva, yalahla umkhondo webhanti. Ukulungiswa kwakungekho torque ephezulu, kodwa ukutshintshela a umgcini nut kunye ne-torque ekhoyo-intambo ephosakeleyo okanye i-ring yeplastiki edibeneyo. Ibonelele ukuba amandla otsalo angaguqukiyo anqongopheleyo.

Ukukhetha izinto eziphathekayo ngomnye umgibe. Kwiindawo ezonakalisayo-cinga ukusetyenzwa kweekhemikhali okanye ukusetyenziswa kolwandle-i-carbon steel keeper nut yiwotshi ekhangayo. Nokuba ngeplating. Ndikhumbula umxhasi owagxininisa kwi-zinc-plated nuts kwindibano yempompo yamanzi elunxwemeni. Umhlwa wegalvanic phakathi kwentsimbi engenasici kunye ne-carbon steel nut zidityanisiwe. Xa isondlo sazama ukulungisa, i-stud yaqhawula. Isisombululo yayikukuluma ibhulethi kwaye usebenzise indibano epheleleyo engama-316, kuquka amantongomane omgcini. Iindleko zangaphambili zaziphezulu, kodwa zaphelisa iphupha elibi lokulungisa.

Emva koko kukho umba wendawo. Indongomane esemgangathweni idinga i-wrench swing efanelekileyo. Kwimiqolomba eqinileyo, unokufuna umgcini wesitayile se-jam-jam, kodwa ukuphakama kwayo okucuthiweyo kuthetha ukubandakanyeka okuncinci komsonto kunye nokusebenza okutshixayo okusezantsi. Ungumsebenzi wokurhweba ukuze ulungele. Kwakhe kwafuneka ukuba siyile isipaneli sespanish esiqhelileyo ukuze nje siqinise indongomane yomgcini ehleli kwibhore ebuyisiweyo. Yongeza iindleko zesixhobo, kodwa yayikuphela kwendlela yokufezekisa zombini i-torque efunekayo kunye noyilo oludibeneyo. I-off-the-shelf ayisoloko iyimpendulo.

Ukubonelela kunye neNyaniso yeeHubhu zokuVelisa

Oku kundizisa ekufuneni. Ukuqhuba umthamo, uhlala ujonga abavelisi kumaqela akhethekileyo amashishini. Enye indawo enkulu yehlabathi iseYongnian, Hebei, China. Ukugxininiswa kwemveliso ye-fastener apho kuyamangalisa. Iinkampani ezifana I-Sunnian Zitai Festener Fishaner Comment Com. usebenze kanye phakathi kwayo. Indawo yabo ekufuphi nomzila kaloliwe omkhulu kunye nothungelwano lohola wendlela ayingomgca weprofayile yenkampani; iguqulela kwimpumelelo yolungiselelo lwempahla ekrwada kunye nokuthunyelwa kwempahla egqityiweyo. Xa ufumana imithwalo yezikhongozeli zeziqhoboshi ezikhethekileyo, ukuba kufutshane nokuthutha imithambo ibalulekile ngeendleko kunye nexesha lokukhokela.

Ukujongana nomvelisi ofana noZitai, ucofa kobo bunzulu, ikhonkco lonikezelo lasekuhlaleni. Kufuneka ibakala elithile le-boron yocingo lwentsimbi yokuqina okuphezulu amantongomane omgcini? Umthengisi kusenokwenzeka ukuba uphantsi kwendlela. Oku kunokwenza iprototyping ibe lula kwaye ivumele iinketho ezininzi zezinto eziphathekayo. Nangona kunjalo, undoqo kukucaca kweenkcukacha. Ndiye ndaneisampulu ezibuyileyo apho unyango lobushushu lwalungachazwanga kuba umzobo ufuna ukulingana kweBanga lesi-8 kuneempawu ezichanekileyo zoomatshini kunye nendlela yokuvavanya. Ingqikelelo yayiza kwenziwa kumgangatho ofanayo wendawo, owahluke kancinane. Isifundo: imizobo yokulawula kufuneka iphelele-ikhemikhali yezinto eziphathekayo, uluhlu lobunzima be-Rockwell, ubungqina bomthwalo, uhlobo lokwaleka kunye nobukhulu, iimfuno zokumakisha.

Akunjalo nje ngokufumana inxalenye eyenziwe. Kumalunga nokuyenza yenziwe rhoqo, ibhetshi emva kwebhetshi. Iqabane elilungileyo lobugcisa kummandla onjalo liya kuba nezixhobo zelebhu ye-metallurgical ukunika iicerts, hayi nje isithembiso. Iwebhusayithi inokuthi bakhonza iimarike zehlabathi, kodwa ubungqina kukuvuma kunye nokukwazi ukuhlangabezana nemigangatho ethile yamazwe ngamazwe njenge-ASTM okanye i-DIN, kungekhona nje i-GB. Eso sisihluzo endihlala ndisisebenzisa.

Iiyantlukwano eziKhethekileyo kunye neZifundo

Ngaphandle kwefomu ye-hex esisiseko, amantongomane omgcini morph ngomsebenzi wabo. I-Castellated nuts kunye ne-cotter pins sisitshixo se-classic esilungileyo se-shafts ejikelezayo koomatshini. Iqhinga apha kukulungelelanisa i-drill. Ukuba umngxuma kwibholiti awulungelelaniswanga ngokugqibeleleyo kunye neecastellations kwitorque echanekileyo, unokutsho phantsi kwetorque ukuyilalisa okanye ngaphezulu kwetorque ukuya kwindawo elandelayo. Akukho nto ifanelekileyo. Olona qheliselo lungcono kukusebenzisa intambo yokulinganisa, ekunika ukunyuswa kwe-angular encinci yokulungelelaniswa, ukunciphisa ukuhambelana kwe-torque.

Emva koko unamantongomane omgcini weflange. Iwasha edibeneyo yobuso isasaza umthwalo kwaye inokutsalwa ukuze ilume kwindawo yokukhwelana ukwenzela ukutshixwa okuphuculweyo. Ndizichazile ezi kwiindibano ezidibeneyo apho kufuneka uthintele ukutyumza i-laminate. Umphezulu wokuthwala obanzi ubalulekile. Kodwa qaphela i-serrations-ukuba i-mating surface yi-aluminium ethambileyo okanye i-peyinti egqityiweyo, i-serrations inokugrumba kwaye yenze uhlengahlengiso oluzayo lube buhlungu, ludla ngokukrazula izinto. Ngamanye amaxesha i-flange egudileyo kunye newasha edibeneyo yifowuni engcono.

Enye yezona ntsilelo zinika umdla endizihlalutyileyo yayikwimibhobho yobushushu obuphezulu. Basebenzisa zonke isinyithi, ukumelana nobushushu amantongomane omgcini. Baye babamba kuqala. Kodwa ngexesha lokuhamba ngebhayisikile ye-thermal, amazinga okwandiswa okungafaniyo phakathi kwe-nut (i-stainless) kunye ne-carbon steel flange yabangela ukuba umthwalo we-clamp uhluke kakhulu. Amandongomane awazange akhululeke ngokwengqiqo yemveli, kodwa itywina lasilela kuba i-gasket yaphulukana noxinzelelo kubushushu obugqithisileyo. Ukulungiswa kwakubandakanya ukubala i-coefficients ye-thermal kunye nokutshintshela kwizinto ze-nut ezihambelana ngcono ne-flange, kunye nokusebenzisa i-helical spring washer ukugcina ukuxinezeleka. Yayisisikhumbuzo sokuba umsebenzi womgcini uyaguquguquka ukuba okusingqongileyo.

Umba woLungiso kunye neeNyaniso zeNdawo

Indongomane yomgcini ihlala ithetha uhlengahlengiso lwexesha elizayo. Le ngongoma yefilosofi yoyilo. Kuya kufuneka ucinge ukuba igcisa ebaleni liza kuba nezixhobo ezisisiseko, ekunokwenzeka ukuba zinxitywe, kwaye azinakuba nesitshixo setorque esilinganisiweyo kwiveki ephelileyo. Uyilo kufuneka luxolele. Ngokomzekelo, ukusebenzisa i-double-nut system (indlela ye-jam nut) njengomgcini uyaziwa ngokugqithiseleyo kwinkqubo efanelekileyo-ukuqinisa i-nut ephambili, ngoko umgcini ngokumelene nayo. Ebaleni, bahlala begila zombini phantsi kunye, besenza incithakalo isiphumo sokutshixa. Ukuba ukulungiswa kulindelwe, idizayini enesalathisi esibonakalayo-njengophawu lobungqina okanye intambo ephuma kwixabiso elithile elidlulileyo kwi-nut-ithembeke ngakumbi kunokuthembela kwinkqubo epheleleyo.

I-Lubrication yenye indawo eguquguqukayo. Ngaba uyawakhankanya amandongomane afakwe ngaphambili? Ukuba kunjalo, ngantoni? Okanye ucinga ukuba abasebenzi basendle baya kusebenzisa ngokuchasene nokuthimba? Ndikhe ndabona iindibano apho i-lubricant efakwe kwifektri yomile okanye yatsala igrit, iyijika ibe yintlama erhabaxa enxibe imisonto. Ngakolunye uhlangothi, ndibone iindibano ezomileyo zenyongo kwaye zibambe ngexesha lohlengahlengiso lokuqala. Akukho mpendulo jikelele. Kuba a umgcini nut kwi-stainless steel stud eya kubona ukulungiswa okungaqhelekanga kwindawo eyomileyo, ifilimu eyomileyo ye-molybdenum disulfide inokuchazwa. Kwinto eya kuthi isetyenziswe rhoqo kwindawo emanzi, i-anti-seize yobhedu iyinto eqhelekileyo. I-spec sheet kufuneka iyichaze ngokucacileyo.

Ekugqibeleni, eyona nkqubo ithembekileyo yomgcini endiyisebenzisileyo ihlala iyeyona ilula kakhulu ephendula izinto zabantu. I-nylon-insert locknut (nyloc) ilungile ngexesha elinye okanye uhlengahlengiso olunqabileyo, njengoko ukufakwa kunxiba. I-locknut yentambo egqwethekileyo ingcono kuhlengahlengiso oluninzi. Ngaphandle kohlengahlengiso, i-torque nut ekhoyo enepetshi okanye isitshixo somsonto wekhemikhali inokuba yeyona ilungileyo. Ukhetho alukho kwikhathalogu kuphela; kukumzobo, kunye nemiyalelo ecacileyo. Ngumahluko phakathi kwecandelo elihlala ubomi bomatshini kunye nelo elibangela ukufowuna. Lowo ngumlinganiselo wokwenene womgcini.
