Ipapo pane pfuti huru: tension control bolt (TC bolt) masisitimu ane washer akaomeswa. Aya akanakisa ekubatanidza maflange makuru, senge pane zvimiro zvesimbi kana mhepo turbine hubs. Iwe unoshandisa shear wrench iyo inobvisa iyo spline inopera pane chaiyo tension. Iyo inokupa iwe inooneka, enda/kwete-enda humbowo hwekumisikidza chaiko. Iyo yekusimbisa kona yakajeka: iyo yakanyatso kurodha yejoini inoona kushoma kwehukama kufamba, zvakanyanya kuderedza kushushikana kupfeka uye kuneta. Zvakaipa? Iyo specialized tooling uye yakakwira unit mutengo. Iwe unofanirwa kuzvipembedza kuburikidza nemutengo wehupenyu, kwete kungoshandisa mari yekutanga.

Chiziviso Chinokurumidza paMahara-Spinning Matambudziko

Wakambove nenzungu inotenderera zvakasununguka asi isingamboomese? Kazhinji inorambwa seshinda yakaipa. Dzimwe nguva ndizvo. Asi kazhinji, ibolt thread pitch deformation kubva kune yapfuura-torquing, kana marara akarongedzerwa mukati mekiyi yekuvhara. Chinhu chidiki, chinoshungurudza chinomisa mutsara wegungano rose. Kugadzirisa hakusi kungoita mutsva; iri kuongorora shinda yechirume nejeji uye kuchenesa panosvirana. Zviripachena, asi zvinogara zvichiregeredzwa mukumhanya kuti zvinhu zvifambe.

The Material & Coating Dance

Sustainability zvinoreva zvakare kurwisa ngura, iyo inodya zvinhu uye inowedzera kukakavara, ichichinja hukama hwe torque-tension. Guta rine ngura rinobata kana kurasikirwa nemutoro. We standardized on hot-dip galvanized kana dacromet-yakavezwa fasteners zvekunze, high-humidity applications. Asi heino kubata: machira anowedzera ukobvu. Kana iwe ukasazvidavirira izvo mune yako torque specs, uri pasi-kuomesa. Iyo 15-micron zinc flake coating inogona kuchinja zvakanyanya friction coefficient. Takadzidza kubvunza vatengesi ve torque-tension data kune yavo chaiyo yakavharidzirwa zvigadzirwa, kwete chete base zvinhu. Vamwe, saZitai, vanopa aya machati zviri nyore, izvo zvinoratidza kuti vanonzwisisa mashandisirwo, kwete chete kugadzira.

Sarudzo yemidziyo ndiyo imwe lever. Kufamba kubva pachiyero che8.8 giredhi kuenda ku10.9 kana kunyange 12.9 kunobvumira dhayamita diki bhaudhi kumutoro wakafanana, kuchengetedza huremu uye zvinhu. Asi giredhi repamusoro rinoreva kukanganiswa kwehydrogen embrittlement kana isina kugadziriswa nemazvo. Iwe uri kutengesa imwe njodzi kune imwe. Isu takanga tine batch yemhando yepamusoro-giredhi mabhaudhi akakundikana zvine njodzi pane yekutsikirira yakakodzera-yakaratidza nzira yeplating yakaunzwa haidrojeni, uye haina kubikwa zvakanaka kuti ibude. Mutengesi akapomera torque yedu yekuisa. Chakanga chiri chidzidzo chakakanganisika mukutarisa iyo yese yekugovera cheni maitiro ekutonga.

Kuiswa: Kupi Iyo Yakanakisa Tech Inoenda Kufa

Iyi ndiyo huru canyon pakati pedzidziso nekuita. Iwe unogona kutsanangura iyo yakakwana Nord-Lock washer seti kana yakaomesesa polymer chigamba chekusimbisa. Kana mukomana ane chipanera chekukanganisa asingazivi maitiro, hazvina maturo. Calibrated torque wrenches inofanirwa, asi inotariswa kangani? Isu takaita hurongwa uko majoini akakosha (funga magiya bhokisi anokwirisa, zvimiro zvinongedzo) zvinoda yakasainwa-yakavharwa torque log ine chishandiso ID. Yainzwa seyakarongeka, asi yakacheka kukundikana kwakabatana pamwe ne70%.

Kutevedzana kunokosha zvakare, kunyanya pa-multi-bolt flanges. Iyo yekare nyeredzi muenzaniso inodzidziswa nechikonzero-inovimbisa kunyangwe gasket kana kudzvanywa kwepamusoro. Ndakaona mechanics ane nguva achifuratira izvi pane hydraulic manifold, zvichitungamira kune kunoramba kudonha kwavakadzinganisa kwemavhiki nekusimbisa bhaudhi rimwe kakawanda. Vakashandura flange. Dzimwe nguva iyo yakanyanya kusimba yekudzivirira-kusunungura tekinoroji ipepa: yakajeka, ine mifananidzo yebasa rairo.

Kune zvakare chimiro chemunhu chekunzwa. Ane ruzivo fitter dzimwe nguva anogona kuona chinjikira-tambo kana bhaudhi rinoburitsa nekuchinja kwekupokana panguva yekuomesa, chimwe chinhu chikwiriso che torque yematsi chinongoputika. Iyo tactile mhinduro idanho risingadzoreki rekutonga kwemhando. Takatanga kubatanidza mihoro mitsva nevaya veterans zvakanangana neakakomba mabhaudhi mabasa, tichitora iyo tacit ruzivo.

Kutarisa Mberi: Iyo Smart Joint?

Pane kutaura nezve smart fasteners ine embedded sensors yekutarisa preload. Ini ndinopokana nekushandiswa kwakapararira. Mutengo, kuoma, uye kusimba munzvimbo dzakaoma dzeindasitiri zvipingaidzo zvakakura. Parizvino, imwe nzira inoshanda yakangwara iri kushandisa ultrasonic bhaudhi elongation kuyerwa kwekukosha, kumwe-kumisikidzwa senge hombe turbine nheyo. Iyo inokupa yakananga kuyerwa kwemutoro, ichipfuura ese akasiyana friction. Inodhura uye inononoka, asi kune mubatanidzwa haumbodi kukundikana, ndiyo yekupedzisira cheki.

Muganhu chaiwo, mukuona kwangu, uri mukugadzira disassembly uye kugadzirisa. Sustainable machines inoda kushandiswa. Anti-kusunungura tekinoroji inobata yakasimba mushure memakore mashanu (ini ndakakutarisa, mamwe makemikari threadlockers) inopesana nekugadzikana. Iyo yakanaka ijoinhi rinogara rakaiswa panguva yekushanda asi rinogona kupatsanurwa neyakajairwa maturusi panguva yekudzokorora. Ndosaka ndinosendamira kumakanika, anogonekazve kukiya zvinhu. Vanogona kuzoda kutsiviwa mushure memazuva mashoma, asi zviri nani pane kucheka kana kudhirowa bhaudhi uye kukuvadza zvinhu zvevabereki.

Pakupedzisira, ndiwo mutambo wehurongwa. Iwe haugone kungo bhaudhi pakusimudzira. Inotanga nejoinhi yakanyatsogadzirwa, inosarudza yakakodzera, yakasimba yekuvhara tekinoroji yezvakatipoteredza, inoita nemazvo, uye zvirongwa zvehupenyu hwese. Makambani anopa zvikamu zvemuviri uye kushandisa uchenjeri, kufanana chikwata pa Zitai Forteners kunze kweiyo huru Handan yekugadzira base, iva vanobatana, kwete vatengesi chete. Nekuti iyo yakanyanya kusimba yekusungirira ndiyo yaunoisa nemazvo, kamwe, wobva wakanganwa nezve hupenyu hwemuchina.
