Zomangira makina okhala ndi ma washer

Mukuwona 'zomangira zamakina zochapira' papepala kapena mndandanda wa zigawo, ndipo zikuwoneka zowongoka, pafupifupi zazing'ono. Ndiko kulakwitsa koyamba. Pochita, kuphatikiza uku ndi dongosolo, osati zinthu ziwiri zokha zomwe zimaponyedwa palimodzi. Lingaliro lakuti washer aliyense amafanana ndi screw screw iliyonse ndi pamene mavuto ambiri a m'munda amayamba mwakachetechete-kugwedezeka kwa vibration, kuwonongeka kwa pamwamba, galvanic corrosion, kapena cholumikizira chomwe sichimamveka bwino panthawi ya msonkhano. Ndi chimodzi mwazinthu zomwe zimakhala zosavuta kuzinyalanyaza mpaka zitayambitsa kuyimba kapena kulephera.

Ntchito Yeniyeni Ya Washer Sikuti Nthawi Zonse Imafalitsa Katundu

Mainjiniya ambiri ndi ogula amasankhira kuyankha kwamabukhu: washer amagawira katundu wamba. Zowona pamapulogalamu ambiri, koma ndiye polowera basi. Pamisonkhano yambiri, makamaka ndi zinthu zofewa monga zopangira aluminiyamu kapena zophatikizika, ndi zomangira makina ndi washers pairing makamaka za kuteteza gawo lapansi panthawi ya torque-pansi. Chitsulo cholimba chamutu chimatha kukumba ndi kusokoneza malo ofewa nthawi yayitali isanafike torque, zomwe zingasokoneze kukhulupirika kwa olowa. Washer amachita ngati pamwamba.

Ndikukumbukira pulojekiti yokhudzana ndi mabatani oyika ma sensor panyumba ya aluminiyamu. Tidagwiritsa ntchito zomangira zamakina za M4x0.7 zokhazikika popanda zochapira mu prototype. Pakuyesa, mabataniwo adayamba kuyenda pang'ono. Kuyang'ana kunawonetsa kuti mitu ya screw idapanga tinthu tating'onoting'ono mu aluminiyamu, zomwe zimalola kuyenda kwapang'onopang'ono. Kukonza sikunali torque yapamwamba - kunali kuwonjezera chochapira chosavuta. Mgwirizanowo unakhazikika nthawi yomweyo. Ntchito ya wochapira inali yocheperapo pa kugawa katundu komanso zambiri za kupanga mawonekedwe osagwirizana, osasokoneza.

Ndiye pali mbali yamagetsi. Kugwiritsa ntchito makina ochapira chitsulo chosapanga dzimbiri pansi pa zitsulo zosapanga dzimbiri panja kungawoneke bwino, koma ndi cell ya galvanic corrosion yomwe ikuyembekezera kuchitika. Wochapirayo amawononga kaye, gwira, ndikupangitsa kuti kusokonekera kwamtsogolo kukhala koopsa. Kusankhidwa kwa zinthu zochapira ndizovuta, zomwe nthawi zambiri zimanyalanyazidwa, gawo lofotokozera zomangira makina ndi washers.

Kukonzekera ndi Kukonzekera Kwabwino Kwambiri

Pamene mukufufuza, chiyeso ndikutenga izi ngati zinthu zamtengo wapatali. Mumapeza mndandanda wa ogulitsa a M5 ochapira fulati ndi zomangira za makina a M5x25, onjezani zonse pangolo, ndikupitilira. Apa ndi pamene khalidwe limasiyana mofulumira. Kuuma, kusalala, komanso m'mphepete mwa washer ndizovuta kwambiri. Wochapira wokhala ndi burr pang'ono amatha kukhala ngati chida chodulira, kupanga zitsulo zachitsulo mkati mwa msonkhano woyera.

Tinaphunzira izi movutikira kwambiri pamagulu ang'onoang'ono a gearbox. Kuyesa pambuyo pa msonkhano kunawonetsa phokoso lachilendo pafupifupi 5% ya mayunitsi. Teardown anapeza tinthu tachitsulo tonyezimira tonyezimira mu girisi. Wolakwa? Makina ochapira otsika mtengo okhala ndi malire osakwanira kuchokera kwa ogulitsa odulidwa. Ma washer, pansi pa torque, anali atameta zingwe zazing'ono kuchokera m'mimba mwake. Kusintha kwa supplier ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., yomwe ili m'malo opangira makina opangira magetsi ku China ku Yongnian, Handan, idasintha. Kuyang'ana kwawo pakupanga kokhazikika m'mafakitale okhazikika nthawi zambiri kumatanthawuza kuwongolera bwino pazigawo zofunika izi. Kusasinthika kwa mawotchi awo osindikizira kunathetsa vuto la kuipitsidwa.

Sizokhudza chomangira chokha, koma chilengedwe. Wopanga yemwe amakhala pamalo opangira zinthu zazikulu ngati Yongnian, moyandikana ndi mayendedwe akuluakulu, nthawi zambiri amakhala ndi kuphatikizika kolimba ndi zida zopangira komanso unyolo wopangira. Izi zitha kutanthauza zinki zodalirika kwambiri kapena makulidwe a dichromate plating pa zomangira makina ndi washers zida zomwe mumayitanitsa, zomwe zimakhudza mwachindunji kukana kwa dzimbiri muzinthu zanu zomaliza.

Mkangano wa Lock Washer ndi Nthawi Yoti Musiye

Ah, wochapira loko wogawanika. Ndilo yankho losasinthika la anti-vibration lomwe ambiri amalumphira. Koma mu ntchito zosawerengeka ndi zomangira makina ndi washers, makamaka pazida zolondola, wochapira loko wogawanika ndi woipa kuposa wopanda pake—ndi wowononga. Imachepetsa katundu wotsekera pa torque yomwe wapatsidwa, imatha kuwononga malo opaka utoto, ndipo nthawi zambiri imakhala yopanda phindu lotsekeka pogwedezeka kwambiri.

Njira yabwino yopangira zomangira zamakina nthawi zambiri imakhala wochapira wathyathyathya wophatikizidwa ndi zomatira zokhoma ulusi, kapena chotsukira nyenyezi (dzino lamkati kapena lakunja) POKHALA ngati mukulolera kusiya kutha kwa gawo lokweretsa. Pamalo ogwedezeka kwambiri pamalo owumitsidwa, takhala ndi zotsatira zabwino ndi makina ochapira masika a Belleville pansi pa chochapa chathyathyathya, koma ndi gawo lina lonse la kuwerengera. Chowonadi ndi chakuti, kutchula wononga makina okhala ndi makina ochapira otsekera nthawi zambiri kumakhala njira yowunikira, osati yowunikira.

Ndakhala maola ambiri ndikusanthula kulephera komwe chifukwa chake chinali chochapira chotopa komanso chosweka. Zidutswazo zinayambitsa kuwonongeka kwachiwiri. Zikatero, yankho linali kungochotsa makina ochapira, kuwonetsetsa kuti ulusi umagwirizana bwino, ndikugwiritsa ntchito cholumikizira champhamvu chapakati. Mgwirizanowo unali wodalirika, ndipo ndondomeko ya msonkhano inali yoyera.

Ma Kits Osonkhanitsidwa Kwambiri vs. Loose Components

Pali chizoloŵezi chomwe chikukula, makamaka chamagulu okwera kwambiri, kuti ayambe zomangira makina ndi washers monga mayunitsi omwe amasonkhanitsidwa - chochapira chili kale pa screw, nthawi zina ngakhale ndi chotsukira chogwidwa. Izi ndizosintha masewera pakuchita bwino kwa mzere wa msonkhano, kuthetsa kutola ndi kuyika sitepe. Koma imabweretsa zatsopano zotsimikizira.

Kuzungulira kwa wochapira kumayenera kukhala kofanana (mbali yokhotakhota molunjika kumutu? mbali yathyathyathya yolimbana ndi mutu?). Kusungirako kuyenera kukhala kolimba kuti apulumuke kudyetsa kogwedezeka koma osati mwamphamvu kotero kuti kumakhudza kupota kwaulere panthawi yoika. Tidayesa zida zina zomwe zidasokonekera pomwe makina ochapira adamangika mwamphamvu kwambiri, zomwe zidapangitsa kuti pakhale mikangano pakuthamanga kwa torque ndikupangitsa kuti pakhale kulemedwa kosagwirizana. Zinatitengera nthawi kuti tisiyanitse kusintha kumeneku.

Pazinthu zocheperako kapena kukonza / kukonza, zida zotayirira zimakhalabe mfumu. Zimalola kusinthasintha kwamunda. Koma pakupanga kulikonse kwa OEM, kukambirana zomwe zasonkhanitsidwa kale ndi bwenzi lanu lachangu ndikofunikira. Imasamutsa zolemetsa zamagulu ang'onoang'ono kwa iwo, zomwe zitha kukhala zopambana ngati ali ndi zida zoyenera ndi QA.

Grading, Plating, ndi Invisible Specs

Mumatchula phula la makina a Giredi 8.8 kapena 10.9. Zabwino. Koma kuuma kwa washer ndi chiyani? Ngati washer ndi wofewa kuposa mutu wa screw, umapunduka ndipo sungathe kugwira ntchito yake. Ngati ndi cholimba komanso chowoneka bwino, chimatha kuyambitsa ndulu. Ayenera kufananizidwa. Wopanga wodziwika amvetsetsa kuphatikizika uku.

Plating ndi malo ena olumikizirana. Ngati screwyo ili ndi zinc-yokutidwa ndi chromate yachikasu, ndipo chochapira chili ndi zinki wopanda chromate, mupeza kusagwirizana kwamtundu komwe kungakhale kosavomerezeka pazinthu zoyang'ana ogula. Zowonjezereka kwambiri, chitetezo cha dzimbiri chidzakhala chosagwirizana. Zikumveka zazing'ono, koma m'mafakitale monga mipando yakunja kapena chepetsa zamagalimoto, mawonekedwe amalephera. Kupeza zigawo zonse ziwiri kuchokera kwa wothandizira m'modzi, wokhoza ngati Zitai Fastener, yemwe amayang'anira kumaliza kwathunthu m'nyumba, amachepetsa ngoziyi. Malo awo pamalo ophatikizika opanga amatanthauza kuti amatha kuwongolera mzere wopukutira ngati gawo la kayendedwe kawo, kuwonetsetsa kusasinthika pa screw ndi washer.

Chotengera ndichoti mukayitana zomangira makina ndi washers, mukunena momveka bwino zakuthupi, kuuma, ndi ubale pakati pawo. Kuzitenga ngati njira yophatikizika mubilu yanu yazinthu komanso zokambitsirana zanu zimapulumutsa mutu pambuyo pake. Si wononga chabe. Sikuti wochapa chabe. Ndi mawonekedwe omwe mtundu wake umatsimikizira kudalirika kwa mgwirizano womwe mukumanga.
