Iwe unoona yakada kufanana ne10U1 4U5 16 square U-bolt yakakandwa kumativi, uye kana usina kudzika mupombi zvinotsigira kana zvimiro zvekugadzira, inogona kunge iri hieroglyphics. Chokwadi ndechekuti, kunyangwe vamwe vakomana vane ruzivo vanogumburwa vachifunga kuti gumi nematanhatu inoreva dhayamita yebhaudhi-hazviiti. Ndiyo inowanzoita sikweya dimension, hupamhi hwepamusoro pemafurati eU-bolt's bend. Nyama chaiyo iri mu10U1 uye 4U5, iyo inowanzova yevaridzi kana yedunhu coding yekutakura ratings uye dimensional series. Ngatiparadze zvauri kutsvaga chaizvo kana mumwe munhu akumbira izvi.

Kugadzirisa iyo Alphanumeric Soup

Kurudyi, saka 10U1 uye 4U5. Mune akawanda makata, kunyanya kubva kune makuru ekugadzira hubs seyeChina Yongnian dunhu, iyo U inoreva U-bolt nhevedzano. Nhamba yapfuura kazhinji ine chekuita nekirasi yekuita kana maitiro. 10U1 inogona kuratidza inorema-basa nhevedzano, pamwe kune hombe pombi madhayamita kana yakakwira seismic mitoro, nepo 4U5 ingave yakareruka nhevedzano. Iyo 1 ne5 ingangove yekudzokorora kana sub-style macode. Iwe haugone kuwana izvi muASTM zviyero; ndeye fekitori-kutaura. Ndinoyeuka ndichidhonza vhudzi rangu kunze-referencing 6U3 kubva kune mumwe mutengesi ane CL-150 kubva kune mumwe-zvakazoitika kuti ivo vaishanda zvakafanana, kungosiyana kwakasiyana. Nguva dzose, gara uchikumbira iyo dimensional kudhirowa.

Iyo 16 square iri kujeka. Izvi zvinotsanangura square U-bolt, uko bend ichokwadi 90-degree angle, isina kutenderedzwa. Iyo 16 ndiyo A dimension, mukati mehupamhi hweU, kazhinji mumamirimita. Saka, iri 16mm kubva mukati megumbo rimwe kusvika mukati merimwe. Izvi zvakakosha pakukodzera pamusoro pedanda kana chiteshi. Chikanganiso chakajairika kuraira 16mm square U-bolt kusungirira 16mm gobvu chinhu-hachizokwane. Iwe unoda clearance, kazhinji mashoma mm mamwe.

Chii chinoshaikwa pano? Kureba kwegumbo (iyo L dimension), saizi yeshinda uye namo (semuenzaniso, M12 x 1.75), zvinhu (plain carbon steel, hot-dip galvanized, 304/316 stainless), uye kupera. Iyo alphanumeric kodhi haiwanzo kusanganisira zvese izvo. Inzvimbo yekutanga, kwete chirevo chakazara. Ndakadzidza izvi nenzira yakaoma pabasa rekugadzirisa mvura; isu takawana 10U1 mabhaudhi panzvimbo, asi aive simbi isina kujeka pataida inopisa-dip galv. Kutumirwa kwese kwakarambwa.

Akakosha Dimensions Ivo Havakuudze

Kureba kwegumbo ndizvo zvese zvekuisa. Kana makumbo ari mapfupi, nzungu dzako hadzizobatanidzi zvizere. Yakareba, uye uri kutambisa zvinhu uye zvinogona kukanganisa kuomarara - gumbo refu, rakatetepa rinogona kukotama pasi pe torque. Kune square U-bolt, iwe unodawo B dimension, iyo yemukati kureba kubva pasi pebhendi kusvika pakutanga kwetambo. Izvi zvinosarudza kuti yakawanda sei zvinhu zvaungabatanidza. Mutemo mukuru: wepombi inosungirira, chiyero cheB chako chinofanira kunge chakakura kupfuura pombi O.D. pamwe neukobvu hwechigaro chechigaro chako kana mutsara, pamwe nemukaha we nzungu newachi.

Thread specification ndiyo imwe gomba. 16 sikweya haitauri nezve dhayamita yetsvimbo. Inogona kunge iri M10, M12, kana kunyange M8 shinda pane 16mm square bend. Kutakura mutoro kunotsamira pane izvi. Nokuti a pombi clamp kuchengetedza 4-inch schedule 40 mutsara, iyo M10 shinda pane 10U1 bhaudhi inogona kunge iri pasi-inotsanangurwa kune ine simba mitoro. Iwe unoda iyo tensile simba uye humbowo mutoro data. Vagadziri vane mukurumbira, senge Handan Zitai Fastener Kugadzira Co, Ltd. yakavakirwa mune iyo huru Yongnian yekugadzira base, kazhinji inopa aya machati. Nzvimbo yavo, zitafasteners.com, ine mapeji akanaka ehunyanzvi kwaunogona kuyambuka-kutarisa akateedzana makodhi achipesana nemakanika chaiwo zvivakwa.

Material uye kupedzisa hazvisi zvinhu zvidiki. Muchirimwa chemakemikari, iyo 4U5 bhaudhi zviri nani kuve 316 isina tsvina. Muchikumbiro cheHVAC chemahombekombe, kupisa-kunyura kwakagadzikwa kuASTM A153 hakugone kutaurirana. Iyo coding 10U1 inogona kunge iine yakasarudzika zvinhu, asi iwe unofanirwa kusimbisa. Ndakaona U-bolt ichitorwa kureva generic, yakabatiswa nekutenga, zvichitungamira mukutadza kukonzeresa nguva isati yakwana pabasa rekupaka garaji. Iyo spec inofanirwa kutaura zvakajeka giredhi rezvinhu uye coating.

Chaiyo-Nyika Yekushandisa uye Mutoro Kufunga

Saka, uri kushandisa izvi kumusangano wepombi clamp. Iyo U-bolt ingori chikamu chimwe chete. Une chigaro (chidimbu chinokambaira pombi), nzungu, uye kazhinji ndiro rinotsigira kana gwara. Basa reU-bolt ndere kugadzira simba rekumanikidza pasina kukanganisa. Sikweya yeU-bolt, senge iyi 16 sikweya, inogara ichipesana neskweya danda, kudzivirira kutenderera-yakatenderedzwa U-bolt dzimwe nguva inogona kutenderera panguva yekuomesa, inova inotyisa munzvimbo dzakasimba.

Iwo akatevedzana macode 10U1 vs. 4U5 angangoenderana nekutakura zviyero. Mune ruzivo rwangu, nhamba yepamusoro inotungamira inowanzoreva dhayamita yakakora yetsvimbo uye inorema bend radius, yakagadzirirwa kukwirisa seismic kana kupisa kwekufamba mitoro. Iwe haugone kungozvichinjanisa. Pabasa rekudzoreredza gore rapfuura, takatsiva mabhaudhi e4U5 ne10U1 pamutsetse wekuwedzera mutsara, asi taifanira kukwidziridza gungano rose resadhi zvakare, sezvo bhaudhi rinorema raida chigaro chakakora kuti chigovere mutoro zvakanaka pakuvharisa pombi.

Torque inokosha zvikuru. Kupfuura-kutenderedza sikweya U-bolt inogona kusimbisa bend, ichigadzira nzvimbo yekutyoka. Under-torquing, uye pombi yako inotsvedza. Kukosha kwe torque kunoenderana nesaizi yeshinda, pitch, uye zvinhu. Iko hakuna imwe-saizi-inokodzera-zvose. Iwe unoda torque yemugadziri tafura yeiyo chaiyo chigadzirwa kodhi. Matafura eGeneric anokutora iwe muballpark asi anogona kudzimwa ne20%.

Sourcing uye Gotcha Factors

Paunenge uchitsvaga chimwe chinhu nekodhi seizvi, iwe unogona kunge uchibata neimwe nzira yemupi. Inobhadhara kuenda yakananga kumugadziri ane tsigiro yeinjiniya. Kambani yakadai Handan Zitai Fastener, yakapihwa nzvimbo yayo mukati memoyo weChina inomhanyisa indasitiri ine yakasimba logistics link, kazhinji ine aya macode akamepurwa kune akadzama ekugadzira specs. Kureruka kuriko, asi basa riri pauri kupa iyo yakazara application mamiriro.

The big gotcha is tolerance. A 16mm square dimension inogona kuve ne +/- 1mm kushivirira. Kana chiteshi chako chesimbi chakasimba 16mm, bhaudhi pa15mm ichave yakasununguka, uye imwe pa17mm haikwane. Nezve maapplication akakosha, iwe unofanirwa kutsanangura kushivirira kwakasimba, izvo zvinogona kukutamisa kubva kune stock chinhu kuenda kune tsika kumhanya. Nguva yekutungamira uye mari inoshanduka.

Chimwe chinyorwa chinoshanda: sikweya U-mabhaudhi, kunyanya muhukuru hukuru, inogona kuve nekutsauka kudiki kubva kune yakakwana 90-degree bend nekuda kwekugadzira uye kutonhora maitiro. Zvakakodzera kukumbira kutwasanuka / kushivirira kwecamber. Ndakatofanira kudzorera batch apo makumbo akatambanudzwa ne 3 degrees, zvichiita kuti zvisakwanisike kuita kuti nzungu dzitange zvakafanana. Mutengesi akanaka achaongorora izvi.

Kuzvidhonza Zvose Pamwe Chete

Saka, kudzokera kuIyo mubvunzo usina kukwana. Kuti uitsanangure nemazvo, unoiwedzera kuchinhu chakaita se: Square U-bolt, Series 10U1 (kana 4U5), kune inorema/yakareruka basa pombi clamp. Mukati upamhi (A): 16mm. Kureba kwegumbo (L): [semuenzaniso, 120mm]. Thread: [semuenzaniso, M12 x 1.75]. Material: [semuenzaniso, Giredhi 8.8 simbi]. Pedzisa: [semuenzaniso, Kupisa-dip kwakabatiswa]. Ichashandiswa nechisharo chinoenderana chepombi O.D. [X].

Iyo yakatevedzana kodhi ipfupi kune avo vanoziva nemutsara wechigadzirwa. Kune vamwe vese, musungo. Gara uchigadzirisa kuita zviyero zvemuviri uye zvinodiwa zvekuita. Shandisa iyo kodhi sereferensi paunenge uchitaura nemutengesi wako, asi usambofa sewayo wega rondedzero padhirowa kana PO.

Pakupedzisira, kuwana chokwadi U-bolt ndeyekunzwisisa sisitimu iyo chikamu chayo. Iyo bhaudhi haishande iri yega. Iyo 16 square dimension inofanirwa kutamba zvakanaka nesimbi yako yekutsigira, iyo 10U1 chiyero inofanira kuenderana nekuverenga kwako kwemutoro, uye zvinhu zvinofanirwa kurarama nharaunda yako. Icho chikamu chidiki, asi kutsanangura zvisirizvo kunogona kutungamirira kune yakawanda rework-vimbise neni, ndanga ndiri mukomana ane wrench yekunaya mumvura, ndichiedza kuita kuti iro risiri iro rikwane.
