Ibholithi njengethuluzi elivame ukusetshenziswa ekufakweni, ukusetshenziswa kwayo kubanzi kakhulu, kodwa ukusetshenziswa kwayo isikhathi eside kuzoletha nezinkinga eziningi, njengokungaxhumani kahle, amandla okubopha anganele, ukugqwala kwebholithi njalo njalo. Ikhwalithi kanye nokusebenza kahle komshini kuzothinteka ngenxa yokuxhumeka okuxekethile kwamabholithi ngesikhathi somshini wokulungisa izingxenye. Ngakho-ke ungayikhulula kanjani ibholithi?
Kunezindlela ezintathu ezivame ukusetshenziswa zokulwa nokukhulula: ukulwa nokukhulula ukucindezeleka, ukulwa nokukhulula ngomshini kanye nokuvimbela ukukhulula unomphela.
- Ibhawodi eliphindwe kabili
Isimiso se-nut elwa nokukhulula phezulu: kunezindawo ezimbili zokungqubuzana lapho ama-nuts amabili elwa nokukhulula. Indawo yokuqala yokungqubuzana iphakathi kwe-nut ne-fastener, kanti indawo yesibili yokungqubuzana iphakathi kwe-nut ne-nut. Ngesikhathi sokufakwa, ukulayishwa kwangaphambili kwendawo yokuqala yokungqubuzana kungu-80% wendawo yesibili yokungqubuzana. Ngaphansi kwemithwalo yokushayisana nokudlidliza, ukungqubuzana kwendawo yokuqala yokungqubuzana kuzoncipha futhi kunyamalale, kodwa ngesikhathi esifanayo, i-nut yokuqala izocindezelwa, okuholela ekwandeni okuqhubekayo kokungqubuzana kwendawo yesibili yokungqubuzana. Ukungqubuzana kokuqala nokwesibili kumele kunqotshwe lapho i-nut ikhululwa, njengoba amandla esibili okungqubuzana enyuka njengoba amandla okuqala okungqubuzana encipha. Ngale ndlela, umphumela wokulwa nokukhulula uzoba ngcono.
Isimiso sokulwa nokuxegiswa kwentambo ephansi: Izibambo zentambo ephansi nazo zisebenzisa amantongomane amabili ukuvimbela ukuxegiswa, kodwa amantongomane amabili ajikeleza ngezindlela eziphambene. Ngaphansi komthwalo wokushayisana nokudlidliza, ukuxegiswa kobuso bokuqala bokuxegiswa kuzoncipha futhi kunyamalale.
- Ubuchwepheshe bokulwa nokuxega kwentambo engu-30°
Kukhona i-bevel engu-30° wedge phansi kwezinyo lentambo yesifazane engu-30° wedge. Uma ama-bolt nuts eqiniswa ndawonye, izinyo ze-bolt zicindezelwa ngokuqinile ngokumelene ne-bevel yentambo yesifazane, okuholela ekuqineni okukhulu kokukhiya.
Ngenxa yokushintsha kwe-Engela ye-conformal, amandla avamile asetshenziswa ekuthinteni phakathi kwezintambo akwi-Engela engu-60° ku-shaft yebholidi, kunokuba abe ngu-30° njengasemicu evamile. Kusobala ukuthi ingcindezi evamile yentambo ye-wedge engu-30° inkulu kakhulu kunengcindezi yokubopha, ngakho-ke ukungqubuzana okubangelwayo okulwa nokukhulula kumele kwandiswe kakhulu.
- Kusukela ku-lock nut
Ihlukaniswe ngezigaba ezilandelayo: esetshenziselwa imishini yokwakha imigwaqo, imishini yezimayini, imishini yemishini yokudlidliza kwamantongomane aqinile kakhulu azikhiyayo, asetshenziswa ezindiza, ezindizeni, emathangini, imishini yezimayini, njengemantongomane azikhiyayo anayiloni, asetshenziswa ukuze asebenze ngengcindezi engaphansi kwama-ATM angu-2 kaphethiloli, uphalafini, amanzi noma umoya njengendawo yokusebenza esetshenziselwa - 50 ~ 100 ℃ izinga lokushisa elizikhiyayo kumkhiqizo, kanye nenati yokukhiya ye-spring clamp.
- Iglue yokukhiya intambo
Iglue evala intambo (i-methyl) i-acrylic ester, i-initiator, i-promoter, i-stabilizer (i-polymer inhibitor), idayi kanye ne-filler ndawonye engxenyeni ethile yeglue.
Uma unembobo edlulayo: dlulisa ibholidi ngembobo yesikulufu, faka inhlaka yokukhiya intambo entanjeni yengxenye ye-meshing, hlanganisa i-nut bese uyiqinisa ku-torque ecacisiwe.
Uma ukujula kwembobo yesikulufu kukhulu kunobude bebholidi, kuyadingeka ukufaka inhlaka yokukhiya entanjeni yebholidi, ukuhlanganisa nokuqinisa ku-torque ecacisiwe.
Uma ubhekene nesimo sembobo engaboni: phonsa iglue yokukhiya phansi kwembobo engaboni, bese ufaka iglue yokukhiya entanjeni yebholidi, uyihlanganise bese uyiqinisa ku-torque ecacisiwe; Uma imbobo engaboni ivulwa phansi, kufakwa iglue yokukhiya kuphela entanjeni yebholidi, futhi akukho glue edingekayo emgodini ongaboni.
Ukuze uthole isimo sokusebenza kwebholidi elinezinhloko ezimbili: iglue yokukhiya kufanele iphonswe emgodini wesikulufu, bese iglue yokukhiya imbozwa ebholidini, bese i-stud ihlanganiswa futhi iqiniswe ku-torque ecacisiwe; Ngemva kokuhlanganisa ezinye izingxenye, faka iglue yokukhiya engxenyeni ye-stud ne-nut, hlanganisa i-nut bese uyiqinisa ku-torque ecacisiwe; Uma imbobo engaboni ivulekile phansi, akukho glue ewela emgodini.
Kuma-fasteners anezintambo ahlanganiswe ngaphambilini (njengezikulufo ezilungisekayo): ngemva kokuhlanganiswa nokuqinisa ku-torque ecacisiwe, phonsa i-glue ekhiyayo endaweni ye-meshing yentambo ukuze uvumele i-glue ingene yodwa.
- I-washer evala ama-double pack evalekile evimbela ukukhiya
Izinyo le-radial saw ebusweni bangaphandle be-washer enezingidi ezihlanganisiwe livalwe ubuso be-workpiece elihlangana nabo. Lapho uhlelo oluvimbela ukukhululeka luhlangana nomthwalo oguqukayo, ukufuduka kungenzeka kuphela ebusweni bangaphakathi be-gasket.
Ibanga lokunwebeka kwe-wedge lock washer maqondana nobukhulu bokunwebeka likhulu kune-longitudinal displacement yentambo yokunwebeka ye-bolt.
- Iphini elihlukanisiwe kanye nenathi enezikhala
Ngemva kokuba inathi seliqinisiwe, faka iphini le-cotter esikhaleni samanathi kanye nembobo yomsila webhawodi, bese uvula umsila wephini le-cotter ukuvimbela ukujikeleza okuhlobene kwenathi kanye nebhawodi.
- Intambo yensimbi yochungechunge ekhululekile
Indlela yokulwa nokuxegiswa kwentambo yensimbi ewuchungechunge ukufaka intambo yensimbi emgodini wekhanda lebholidi, bese uxhuma amabholidi ngochungechunge ukuze avumelane. Kuyindlela ethembekile kakhulu yokuphumula, kodwa kunzima ukuyihlukanisa.
- I-gasket yokumisa
Ngemva kokuba inathi isiqinisiwe, gobisa i-single-lug noma i-double-lug stop washer eceleni kwenathi kanye nesixhumi ukuze ukhiye inathi. Uma amabhawodi amabili edinga ukuvalelwa kabili, ama-double brake washer angasetshenziswa ukwenza ama-nuts amabili avalelane.
- Umshini wokuwasha wasentwasahlobo
Isimiso sokulwa nokuxegiswa kwe-spring washer ukuthi ngemva kokuba i-spring washer isicwebezelisiwe, i-spring washer izokhiqiza ukunwebeka okuqhubekayo, ukuze umbhangqwana wokuxhumanisa intambo ye-nut ne-bolt uqhubeke nokugcina amandla okungqubuzana, ukhiqize umzuzu wokumelana, ukuvimbela i-nut ukuthi ikhululeke.
- Ubuchwepheshe bokubopha okuncibilikisiwe okushisayo
Ubuchwepheshe bokuqinisa ukuncibilika okushisayo, ngaphandle kwesidingo sokuvulwa kwangaphambili, kuphrofayela evaliwe kungathinta ngqo ukuze kufezwe uxhumano, embonini yezimoto kusetshenziswa kakhulu.
Lobu buchwepheshe bokubopha okuncibilikayo okushisayo buyinqubo yokwakha okubandayo yokuzithinta kanye nokuhlangana kwezikulufo ngemva kokuba ukujikeleza kwemoto ngesivinini esikhulu kuqhutshwe ephepheni ukuze kuxhunywe ngomshafu wokuqinisa phakathi kwemishini kanye nokuguqulwa kwepulasitiki okubangelwa ukushisa kokungqubuzana.
- kulayishwe kusengaphambili
Ukuxhumeka kwebholidi elinamandla aphezulu ngokuvamile akudingi izinyathelo ezengeziwe zokulwa nokuxegisa, ngoba amabholidi anamandla aphezulu ngokuvamile adinga amandla amakhulu okuqinisa ngaphambi kokulinganisa, amandla amakhulu okuqinisa ngaphambi kokulinganisa phakathi kwenathi nesixhumi ukuze kukhiqizwe ingcindezi enamandla, lokhu kucindezela kuzovimbela ukujikeleza kwe-torque yokungqubuzana kwenathi, ukuze inathi ingaxegisi.
