Iwe unonzwa 'makeper nuts' uye vanhu vazhinji vanofunga nezve locknut iri nyore, pamwe rudzi rwenaironi yekuisa. Ndiyo yekutanga kusanzwisisa. Mukuita, muchengeti wechokwadi nati, kunyanya mune zvinorema-basa kana vibration-zvinoita maapplication, imhuka yakasiyana. Hazvisi zvekungodzivirira kusunungura; ndezvekuchengeta chaiyo clamp load, kuita sechivharo chenzvimbo, kana kutoshanda semachanical stop. Ndakaona magadzirirwo akawandisa apo nati yakajairwa inotsanangurwa se 'muchengeti,' chete kuita kuti gungano rikundike mukuyedzwa kwemumunda nekuti mainjiniya haana kufunga nezve axial uye radial masimba anobatanidzwa. Izwi iro pacharo rinenge rakapamhama, rinofukidza zvese kubva kujemu nut pahunde revharuvhu kusvika kune yakasarudzika nati ine pini yecotter pane inotenderera shaft. Iyo nuance ndeye zvese.

Iyo Core Basa uye Zvakajairwa Pitfalls

Ngatitorei zvakananga. Basa rekutanga ndere 'kuchengeta' marongero. Semuenzaniso, pane chinogadziriswa chinongedzo, iwe unoseta hurefu, wobva wasimbisa muchengeti nati pakatarisana nekutendeuka kana tsvimbo yekupedzisira muviri. Iyo yekutadza pfungwa pano kazhinji iri under-torquing. Vanhu vanotya tambo dzegalling kana kukanganisa chikamu, saka vanoenda kuchiedza. Zvakaguma nei? Vibration inoita kuti isununguke kwemaawa mashoma. Ndakadzidza izvi nenzira yakaoma pane conveyor system project. Isu takashandisa yakajairwa hex nati semuchengeti pane tensioning tsvimbo. Tarisa torque pachati yegeneric. Mwedzi mitatu gare gare, takanga tavharwa nokuti tsvimbo yakadzokera kunze, ichirasa nzira yebhandi. Kugadzirisa kwanga kusiri torque yakakwirira, asi kuchinjira kune a muchengeti nut ine torque iripo-tambo yakakanganiswa kana mhete yepurasitiki yakabatanidzwa. Yakapa simba rekukwevera risingachinjiki iyo nzungu yakashongedzwa yakashaikwa.

Kusarudza zvinhu ndeimwe musungo. Munzvimbo dzinoparadza - funga kugadzira makemikari kana kushandiswa kwemugungwa - carbon steel muchengeti nati iwachi yekumaka. Kunyangwe neplating. Ndinoyeuka mumwe mutengi aisimbirira pazinc-plated nzungu kuitira gungano repombi yemvura yemahombekombe. Iyo galvanic corrosion pakati pesimbi isina simbi nekabhoni simbi nati zvakabatanidzwa pamwechete. Apo kugadzirisa kwakaedza kugadzirisa, stud yakaputika. Mhinduro yaive yekuruma bara uye kushandisa yakazara 316 stainless gungano, kusanganisira iyo muchengeti nzungu. Mutengo wepamberi waive wakakwira, asi wakabvisa dambudziko rekugadzirisa rinogara richiitika.

Ipapo ndipo pane nyaya yenzvimbo. Nzungu yakajairika inoda chipanera chakakodzera. Mumakomba akasimba, ungangoda muchengeti akatetepa-jam nati, asi kureba kwayo kwakaderedzwa kunoreva kushomeka kweshinda uye kudzika kwekuvhara kuita. Iwe uri kutengesa basa rekukodzera. Isu takambofanira kugadzira chipanera chechipanera chekungosimbisa nati yemuchengeti akagara mubore rakadzikiswa. Yakawedzera mutengo wekushandisa, asi ndiyo chete nzira yekuwana iyo torque inodiwa uye compact dhizaini. Kunze-pasherufu haisi nguva dzose mhinduro.

Sourcing uye Chokwadi cheManufacturing Hubs

Izvi zvinondisvitsa pakutsvaga. Pakumhanya kwevhoriyamu, iwe unowanzo kutarisa vagadziri mune akasiyana maindasitiri masumbu. Imwe nzvimbo huru yepasi rose iri muYongnian, Hebei, China. Kuwanda kwekugadzirwa kwefastener ikoko kunoshamisa. Makambani akadai Handan Zitai Fastener Kugadzira Co, Ltd. shanda pakati payo chaipo. Nzvimbo yavo iri padyo nenjanji huru nemigwagwa mikuru haingori mutsara munhoroondo yekambani; inoturikira kukuita zvakanaka kwekutora zvinhu zvakabikwa uye kupedzwa kwekutakura zvinhu. Paunenge uchitenga midziyo yakawanda yeakasarudzika fasteners, iko kuswedera pedyo kwekutakura zvinhu zvetsinga pamutengo uye nguva yekutungamira.

Kudyidzana nemugadziri akaita saZitai, uri kupinda mune iyo yakadzika, yenzvimbo yekutengesa cheni. Inoda giredhi chaiyo yeboron simbi waya yekukwirira-simba muchengeti nzungu? Mutengesi anogona kunge ari munzira. Izvi zvinogona kufambisa prototyping uye kubvumira zvimwe zvezvinhu zvingasarudzwa. Nekudaro, kiyi ndeyekujeka kwekutaura. Ndakave nemasamples akadzoka uko kurapwa kwekupisa kwanga kusiri kwekutaura nekuti kudhirowa kwakadaidzira Giredhi 8 yakaenzana kwete iyo chaiyo mechaniki zvivakwa uye nzira yekuyedza. Kufungidzira kwaizoitwa kune yakajairika chiyero chenzvimbo, icho chakasiyana zvishoma. Chidzidzo: kudzora madhirowa anofanirwa kunge achipedza-zvinhu chemistry, Rockwell kuomarara renji, humbowo mutoro, rudzi rwekupfeka uye ukobvu, zvekumaka zvinodiwa.

Haisi yekungoita kuti chikamu chiitwe. Zviri pamusoro pekuita kuti igadzirwe, batch after batch. Akanaka tekinoroji mubatsiri mudunhu rakadaro achave nemetallurgical lab michina yekupa macerts, kwete vimbiso chete. Webhusaiti iyi inogona kuti inoshandira misika yepasirese, asi humbowo huri mukudisa kwavo uye kugona kuzadzisa mazinga epasi rese seASTM kana DIN, kwete GB chete. Ndiyo sefa yandinogara ndichiisa.

Kushandisa-Yakasiyana Kusiyana uye Zvidzidzo

Kupfuura iyo yakakosha hex fomu, muchengeti nzungu morph yebasa ravo. Castellated nuts ane cotter pini ndiyo yemhando yepamusoro kiyi yekutenderera shafts pamuchina. Icho chinonyengera apa ndechekugadzirisa chibooreso. Kana gomba riri mubhaudhi risinganyatso kuenderana ne castellations pa torque chaiyo, iwe ungave uri pasi-torque kuiisa kumusoro kana pamusoro-torque kune inotevera slot. Uyewo hazvina kunaka. Iyo yakanakisa tsika ndeye kushandisa yakanaka-pitch shinda, iyo inokupa iwe madiki angular increments yekumisikidza, kuderedza torque compromise.

Zvadaro une flange muchengeti nzungu. Iyo yakasanganiswa yewasher kumeso inogovera mutoro uye inogona serrated kuti irume mukati mekusangana kwepamusoro kuti iwedzere kukiya. Ini ndatsanangura izvi kune akaumbwa magungano kwaunoda kudzivirira kupwanya laminate. Iyo yakafara bearing surface yakakosha. Asi chenjererai ma serrations - kana nzvimbo yekubatanidza iri aruminiyamu yakapfava kana pendi yekupedzisa, serrations inogona kuchera mukati uye kuita kugadzirisa mune ramangwana kurwadza, kazhinji kubvarura zvinhu. Dzimwe nguva flange yakatsetseka ine washer yakasungwa ndiyo iri nani kufona.

Kumwe kutadza kunonakidza kwandakaongorora kwaive papiipi yekupisa kwepamusoro. Vakashandisa zvose-simbi, tembiricha-inodzivirira muchengeti nzungu. Vakabata pekutanga. Asi panguva yekupisa bhasikoro, mutsauko wekuwedzera mwero pakati penati (stainless) nekabhoni simbi flange yakaita kuti chisungiso chisiyane zvakanyanya. Nzungu hadzina kusunungura mupfungwa yechinyakare, asi chisimbiso chakatadza nekuti gasket yakarasika kudzvanywa pakupisa kwakanyanya. Kugadzirisa kwaisanganisira kuverenga macoefficients ekupisa uye kuchinjisa kune nut material inoenderana neflange, uye kushandisa helical spring washer kuchengetedza kunetsa. Chakanga chiri chiyeuchidzo chokuti basa romuchengeti rine simba kana zvakatipoteredza zviri.

The Adjustment Factor and Field Realities

Nzungu inochengeta kazhinji inoreva kugadziridzwa kweramangwana. Iyi ipfungwa yekugadzira. Iwe unofanirwa kufunga kuti tekinoroji mumunda achave nekutanga, pamwe yakapfekwa, maturusi uye haazove ne torque wrench yakarongedzerwa svondo rapfuura. Iyo yakagadzirwa inofanira kukanganwira. Semuenzaniso, kushandisa kaviri-nut system (jam nut nzira) semuchengeti anozivikanwa zvakanyanya nemaitiro akakodzera-kusimbisa nut yekutanga, ipapo muchengeti achipikisa. Mumunda, ivo vanowanzo korokoza ese ari maviri pasi pamwechete, achibvisa iyo yekuvhara maitiro. Kana kugadziridzwa kuchitarisirwa, dhizaini ine chiratidzo chechiratidzo-sechiratidzo chechapupu kana shinda inoburitsa imwe mari yakapfuura nati-inovimbika pane kuvimba nenzira yakakwana.

Lubrication ndechimwe chikamu chemunda. Unotsanangura here pre-lubricated nzungu? Kana zvakadaro, nei? Kana kuti iwe unofungidzira kuti vashandi vemumunda vachashandisa anti-kubata? Ndakaona magungano apo mafuta anoiswa mufekitari akaomeswa kana kukwezva grit, achiishandura kuita dhizaini yaipfeka shinda. Sezvineiwo, ndakaona magungano akaoma nduru uye kubata panguva yekutanga kugadzirisa. Hapana mhinduro yepasi rose. Nokuti a muchengeti nut pane stainless simbi stud iyo ichaona kusagadziriswa kusingawanzoitiki munzvimbo yakaoma, molybdenum disulfide yakaoma firimu inogona kutsanangurwa. Kune chimwe chinhu chichagara chichishandiswa munzvimbo yakanyorova, mhangura-based anti-seiize inowanzoitika. Iyo spec sheet inofanira kuitaura zvakajeka.

Pakupedzisira, iyo yakavimbika muchengeti system yandakaisa kazhinji ndiyo yakapusa inoverengera zvinhu zvevanhu. Iyo nylon-insert locknut (nyloc) yakanaka kune imwe-nguva kana isingawanzo gadziriso, sekupfeka kwekuisa. Iyo tambo yakakanganiswa locknut iri nani kune akawanda kugadzirisa. Pasina kugadzirisa, torque nati iripo ine chigamba kana kemikari-shinda-locker inogona kunge iri nani. Sarudzo haingori mukatalogi; iri pamufananidzo, nemirairo yakajeka. Ndiwo mutsauko pakati pechikamu chinogara hupenyu hwemuchina uye chimwe chinokonzera callback. Ndiyo chiyero chaicho chemuchengeti.
