Bolodi ngati chida chomwe chimagwiritsidwa ntchito kwambiri popanga zinthu, ntchito yake ndi yayikulu kwambiri, koma kugwiritsidwa ntchito kwa nthawi yayitali kumabweretsanso mavuto ambiri, monga kulephera kulumikizana, mphamvu yokwanira yolumikizira, dzimbiri la bolodi ndi zina zotero. Ubwino ndi magwiridwe antchito a makinawo zidzakhudzidwa chifukwa cha kulumikizidwa kosamasuka kwa mabolodi panthawi yokonza ziwalo. Ndiye mungamasulire bwanji bolodi?
Pali njira zitatu zoletsa kumasula zomwe zimagwiritsidwa ntchito kwambiri: njira zoletsa kumasula, njira zoletsa kumasula ndi njira zoletsa kumasula kosatha.
- Boluti iwiri
Mfundo ya nati yoletsa kumasula pamwamba: pali malo awiri okangana pamene nati ziwiri zimaletsa kumasula. Malo oyamba okangana ali pakati pa nati ndi chomangira, ndipo malo achiwiri okangana ali pakati pa nati ndi nati. Pakuyika, kudzaza koyamba kwa malo oyamba okangana ndi 80% ya malo achiwiri okangana. Pansi pa kugwedezeka ndi kugwedezeka, kukangana kwa malo oyamba okangana kudzachepa ndi kutha, koma nthawi yomweyo, nati yoyamba idzakanikizidwa, zomwe zimapangitsa kuti kukangana kwa malo achiwiri okangana kuwonjezere. Kukangana koyamba ndi kwachiwiri kuyenera kugonjetsedwa nati ikamasulidwa, popeza mphamvu yachiwiri yokangana imawonjezeka pamene mphamvu yoyamba yokangana ikuchepa. Mwanjira imeneyi, mphamvu yotsutsa kumasula idzakhala yabwinoko.
Mfundo yoletsa kumasula ulusi pansi: Zomangira ulusi pansi zimagwiritsanso ntchito mtedza wowirikiza kuti zisamasulidwe, koma mtedza uwiriwo umazungulira mbali zosiyana. Pakagwedezeka ndi kugwedezeka, kukangana kwa pamwamba pa kukangana koyamba kumachepa ndi kutha.
- Ukadaulo woletsa kutayirira wa ulusi wa 30°
Pali bevel ya wedge ya 30° pansi pa dzino la ulusi wachikazi wa wedge ya 30°. Pamene mano a bolt alumikizidwa pamodzi, nsonga za mano a bolt zimakanikizidwa mwamphamvu pa bevel ya wedge ya ulusi wachikazi, zomwe zimapangitsa kuti mphamvu yotsekeka ikhale yaikulu.
Chifukwa cha kusintha kwa Ngongole ya conformal, mphamvu yachibadwa yomwe imagwiritsidwa ntchito polumikizana ndi ulusi imakhala pa ngongole ya 60° ku bolt shaft, osati 30° monga momwe zimakhalira ndi ulusi wanthawi zonse. N'zoonekeratu kuti mphamvu yachibadwa ya ulusi wa 30° wedge ndi yayikulu kwambiri kuposa mphamvu ya clamping, kotero kupsinjika komwe kumachitika chifukwa cha anti-loosening kuyenera kuwonjezeka kwambiri.
- Popeza nati yotseka
Imagawidwa m'magulu awa: yogwiritsidwa ntchito pamakina omanga misewu, makina omangira migodi, zida zamakanika kugwedezeka kwa mtedza wodzitsekera wokha wamphamvu kwambiri, wogwiritsidwa ntchito mumlengalenga, ndege, matanki, makina omangira migodi, monga mtedza wodzitsekera wokha wa nayiloni, womwe umagwiritsidwa ntchito pamagetsi ogwirira ntchito osapitirira 2 ATM ya mafuta, palafini, madzi kapena mpweya monga njira yogwirira ntchito yomwe imagwiritsidwa ntchito pa - 50 ~ 100 ℃ kutentha komwe kumazungulira nati yodzitsekera yokhazikika pa chinthucho, ndi nati yotseka ya spring clamp.
- Guluu wotseka ulusi
Guluu wotseka ulusi ndi (methyl) acrylic ester, woyambitsa, wolimbikitsa, wokhazikika (polymer inhibitor), utoto ndi chodzaza pamodzi mu gawo linalake la guluu.
Kuti mulowetse bowo kudzera m'bowo la screw, ikani guluu wotseka ulusi ku ulusi wa gawo la meshing, konzani natiyo ndikuyimangirira ku mphamvu yomwe yatchulidwa.
Ngati kuya kwa dzenje la screw kuli kwakukulu kuposa kutalika kwa bolt, ndikofunikira kugwiritsa ntchito guluu wotsekera ku ulusi wa bolt, kusonkhanitsa ndi kumangirira ku torque yomwe yatchulidwa.
Pa vuto la dzenje losawona: ponyani guluu wotsekereza pansi pa dzenje losawona, kenako ikani guluu wotsekereza ku ulusi wa bolt, sonkhanitsani ndikulimbitsa ku mphamvu yomwe yatchulidwa; Ngati dzenje losawona latsegulidwa pansi, guluu wotsekereza wokha ndi womwe umayikidwa pa ulusi wa bolt, ndipo palibe guluu wofunikira mu dzenje losawona.
Pa ntchito ya bolt yokhala ndi mitu iwiri: guluu wotsekeka uyenera kuponyedwa mu dzenje la screw, kenako guluu wotsekeka umakutidwa pa bolt, ndipo stud imasonkhanitsidwa ndikumangiriridwa ku torque yosankhidwa; Mukasonkhanitsa ziwalo zina, ikani guluu wotsekeka ku gawo la meshing la stud ndi nati, sonkhanitsani nati ndikuyimangirira ku torque yosankhidwa; Ngati dzenje losawona latsegulidwa pansi, palibe guluu wotayika m'dzenjemo.
Pa zomangira zolumikizidwa kale (monga zomangira zosinthika): mutatha kuzilumikiza ndikuzilimbitsa ku mphamvu yofunikira, ikani guluu wotseka pamalo olumikizira ulusi kuti guluu lilowe lokha.
- Chotsukira chotchingira mapaketi awiri chotseka mkati mwa wedge-in
Dzino la radial saw pamwamba pakunja kwa makina ochapira otsekedwa limatsekedwa ndi malo ogwirira ntchito omwe amakhudza. Pamene makina oletsa kumasula akukumana ndi mphamvu yosinthasintha, kusuntha kungachitike pamwamba pa gasket.
Mtunda wokulirapo wa wotchi yotchingira wedge lock poyang'ana makulidwe okulirapo ndi waukulu kuposa kutalika kwa ulusi wokulirapo wa bolt.
- Pin yogawanika ndi nati yodulidwa
Pambuyo poti nati yalimba, ikani pini ya cotter mu malo olumikizira nati ndi dzenje la kumbuyo kwa bolt, ndikutsegula mchira wa pini ya cotter kuti mupewe kuzungulira kwa nati ndi bolt.
- Zitsulo zamtundu wa waya zomasuka
Njira yoletsa kumasula waya wachitsulo wotsatizana ndi kuyika waya wachitsulo mu dzenje la mutu wa bolt, ndikulumikiza mabolts motsatizana kuti agwirizane. Ndi njira yodalirika kwambiri yopumulira, koma ndizovuta kusokoneza.
- Gasket yoyimitsa
Pambuyo poti nati yalimba, pindani chotsukira cha single-lug kapena double-lug kumbali ya nati ndi cholumikizira kuti mutseke natiyo. Ngati mabolt awiri amafunika kulumikizidwa kawiri, mawaya awiri a brake angagwiritsidwe ntchito kupanga nati ziwirizo kukhala brake imodzi.
- Chotsukira cha masika
Mfundo yoletsa kumasula kwa makina ochapira a masika ndi yakuti makina ochapira a masika ataphwanyika, makina ochapira a masika amapanga kusinthasintha kosalekeza, kotero kuti kulumikizana kwa ulusi wa nati ndi bolt kupitirire kukhala ndi mphamvu yokangana, kupanga nthawi yolimbana, kuti nati isatuluke.
- Ukadaulo womangirira wotentha
Ukadaulo wothira moto wosungunuka, popanda kufunikira kotsegulira pasadakhale, ukhoza kugwiritsidwa ntchito mwachindunji kuti ugwirizane ndi makina otsekedwa, ndipo makampani opanga magalimoto amagwiritsa ntchito kwambiri.
Ukadaulo womangirira wotentha uwu ndi njira yopangira zinthu zozizira yodzigwira yokha ndi screw joint pambuyo poti injini yazungulira mofulumira kwambiri kupita ku pepala kuti ilumikizidwe kudzera mu shaft yomangira pakati pa chipangizocho ndipo kusintha kwa pulasitiki kumachitika chifukwa cha kutentha kwa friction.
- zodzaza kale
Kulumikizana kwa bolt yamphamvu kwambiri nthawi zambiri sikufuna njira zina zotsukira, chifukwa mabolt yamphamvu nthawi zambiri amafunikira mphamvu yayikulu yomangitsa, mphamvu yayikulu yomangitsa pakati pa nati ndi cholumikizira kuti apange kupanikizika kwamphamvu, kupanikizika kumeneku kudzaletsa kuzungulira kwa torque ya nati, kotero natiyo sidzatayika.
