1. Nhanganyaya kuDIN Standards yeChain Technology
DIN Standards, yakagadzirwa neGerman Institute for Standardization (Deutsches Institut für Normung), inomiririra imwe yehurongwa hwehunyanzvi hwakakwana uye hunozivikanwa zvakanyanya hwecheni dzesimbi dzakatenderera uye dzinobatanidza pasi rose. Mitemo iyi inogadza zvirevo zvakananga zvekugadzira, kuyedza, uye kushandiswa kwecheni dzinoshandiswa muzvikamu zvakasiyana-siyana zvemaindasitiri zvinosanganisira kusimudza, kutakura, kusungira, uye kutumira simba. Zvinodiwa zvehunyanzvi zvakasimba zviri mumitemo yeDIN zvinovimbisa kuchengetedzeka kwakanyanya, kuvimbika, uye kushanda pamwe chete kwemasisitimu echeni anoshandiswa mukushandiswa kwakasimba kwemaindasitiri nemakanzuru. Tsika dzeinjiniya dzeGerman dzakaisa DIN standards sezviyero zvemhando yepamusoro, nemiyero yakawanda yepasi rose inoenderana kana kubva kuDIN specifications, kunyanya mumunda we round link chain technology uye mechanical power transmission systems.
Maitiro akarongeka eDIN standards anofukidza hupenyu hwese hwezvigadzirwa zve round link chain—kubva pakusarudza zvinhu uye maitiro ekugadzira kusvika pakuedza nzira, zvinodiwa zvekugamuchirwa, uye pakupedzisira kurega basa. Iyi holistic standardization framework inopa vagadziri nhungamiro yakajeka yehunyanzvi uku vachipa vashandisi vekupedzisira fungidziro dzekushanda dzakavimbika uye vimbiso dzekuchengetedza. Mitemo iyi inogadziriswa nguva nenguva kuti isanganise kufambira mberi kwetekinoroji, kugadzirisa matambudziko ekuchengetedza, uye kuratidza zvinodiwa zvekushandisa zviri kuchinja, zvichichengetedza kukosha kwayo munzvimbo yeindasitiri iri kuwedzera kukura uko kuenderana kwemidziyo uye kushanda kwayo zviri zvinhu zvinonyanya kukosha kune nyanzvi dzeinjiniya nevanotsanangura michina.
2. Kukura uye Kurongwa kweRound Link Chains
Mitemo yeDIN inopa kupatsanurwa kwakadzama kwecheni dzesimbi dzakatenderera zvichienderana nekushandiswa kwadzo, magiredhi ekushanda, uye hunhu hwejometri. Cheni dzakarongwa zvakarongeka zvichienderana nebasa radzo guru—kungave kwezvinangwa zvekusimudza, masisitimu ekutakura, kana mashandisirwo ekusungira—nechikamu chimwe nechimwe chine zvikamu zvakati wandei zvichienderana nematanho ehunyanzvi. Chikamu chakakosha chekupatsanurwa imhando yecheni yekubatanidza, ine 5d (kashanu dhayamita yezvinhu) inomiririra zvirevo zvakafanana zvepitch yecheni dzekutakura sezvinoonekwa muDIN 762-2, iyo inonyanya kufukidza cheni dzesimbi dzakatenderera nepitch 5d yecheni dzekutakura, dzakaiswawo muGrade 5 nekudzimwa uye tempered treatment yehunhu hwakavandudzwa hwemakanika.
Tsanangudzo yemhando yezvinhu inomiririra chimwe chikamu chakakosha chekupatsanura mukati meDIN standards, zvichiratidza hunhu hwemakanika echeni uye kukodzera kwemamiriro akasiyana ebasa. Semuenzaniso, kushanduka kubvaDIN 764-1992 ye "giredhi rechi30", pinda cheni dze 3.5d" kusvika pari zvinoDIN 764-2010 ye "giredhi 5"", yakadzima uye yakanyoroveswa" inoratidza kuti kuvandudzwa kwezvinhu kwakagadziriswa sei kuburikidza nekuvandudzwa kwakajairwa. Kurongwa uku kwegiredhi kunoenderana zvakananga nekukwanisa kwecheni kutakura mutoro, kuramba kupfeka, uye nguva yekuneta, zvichigonesa vagadziri kusarudza cheni dzakakodzera zvinodiwa zvekushanda. Mitemo iyi inosiyanisa cheni zvichienderana nezvinodiwa zvekuongorora nekugamuchirwa, dzimwe dzichida kusimbiswa kwakayerwa uye kwakaedzwa sezvakatsanangurwa muDIN 764 (1992) yakatsiva "cheni dzakayerwa uye dzakaedzwa dzesimbi dzakatenderera".
3. Kushanduka kwehunyanzvi hweMitemo Yakakosha
Kushanduka kwemaitiro eDIN kunoratidza kufambira mberi kwetekinoroji mukugadzira cheni, sainzi yezvinhu, uye maitiro ekugadzira. Kuongorora nhoroondo dzekudzokorora kwakajairika kunoratidza maitiro ekuvandudzwa kunofambira mberi mune zvinodiwa zvetekinoroji uye kufunga nezvekuchengetedza. Semuenzaniso, DIN 762-2 yakashanduka zvakanyanya kubva mushanduro yayo ya1992, iyo yakataura nezve "giredhi 3" cheni, kusvika kune yazvino vhezheni ya2015 inotsanangura cheni dze "giredhi 5, dzakadzimwa uye dzakanyoroveswa" dzinoshanda zvakanyanya. Kushanduka uku hakungomiriri shanduko mukutsanangurwa asi kunomiririra kuvandudzwa kukuru muzvimiro zvezvinhu, maitiro ekurapa kupisa, uye tarisiro yekushanda, pakupedzisira zvichikonzera cheni dzine hunhu hwepamusoro hwemakanika uye hupenyu hwebasa hwakareba.
Saizvozvowo, kukura kweDIN 22258-2 yekubatanidza cheni yerudzi rweKenterinoratidza kuti zvinhu zvekubatanidza zvakagadzirwa sei kuti zvive nechokwadi chekuti sisitimu yakavimbika. Yakatanga kuunzwa muna 1983 uye yakazogadziriswazve muna 1993, 2003, uye munguva pfupi yapfuura muna 2015, chiyero ichi chakabatanidza zvinodiwa zvakanyanya zvekugadzira connector, zvinhu, uye kuyedza. Kugadziriswa kwazvino kwa2015 kunosanganisira mapeji gumi nemasere etsanangudzo dzakadzama, zvichiratidza nzira yakazara yakatorwa yekugadzirisa chikamu ichi chakakosha chekuchengetedza mumaketani. Maitiro akafanana ekuvandudzwa kwechiyero - kazhinji makore gumi kusvika gumi nemaviri ega ega pamwe nekuchinja kwepakati - kunoita kuti zviyero zveDIN zvirambe zviri pamberi pekuchengetedza nekushanda uku zvichisanganisira mhinduro dzinoshanda kubva kumashandisirwo emaindasitiri.
4. Kugadziriswa kweChain Connectors neZvishongedzo
MaChain Connectors anomiririra zvinhu zvakakosha mumasisitimu edenderedzwa remaketani, zvichiita kuti pave nekuungana, kupatsanurwa, uye kugadziriswa kwehurefu ukuwo cheni ichichengetedza kusimba kwechimiro uye kugona kwayo kutakura mutoro. Mitemo yeDIN inopa zvirevo zvakakwana zvemhando dzakasiyana dzemaketani, neKenter type connectors dzakanyatsotsanangurwa muDIN 22258-2. Aya ma connectors akajairwa akagadzirwa kuti aenderane nesimba uye mashandiro emaketani aanobatana nawo, ane zvirevo zvakadzama zvinofukidza saizi, zvinhu, kupisa, uye zvinodiwa pakuyedza. Kugadzwa kwema connectors kunovimbisa kushanda pamwe chete pakati pemaketani kubva kuvagadziri vakasiyana uye kunoita kuti basa rekugadzirisa nekugadzirisa rifambe zvakanaka mumunda.
Kukosha kwekugadzirisa connector kunopfuura kuenderana nehunyanzvi asi kunosanganisira zvinhu zvakakosha zvekuchengetedza. Semuenzaniso, mukusimudza mashandisirwo, kukundikana kweconnector kunogona kuva nemigumisiro yakaipa, zvichiita kuti zvirevo zvakasimba mukati meDIN standards zvive zvakakosha pakuderedza njodzi. Standards dzinogadza zvinodiwa pakushanda, interface geometry, uye nzira dzekuyedza dzinofanirwa kuteverwa neconnectors dzisati dzaonekwa sedzinogamuchirwa pabasa. Iyi nzira yakarongeka yekugadzirisa connector inoratidza huzivi hwakazara hwekuchengetedza huri mukati meDIN standards, uko chikamu chega chega chiri munzira yekutakura chinofanira kusangana nezvinodiwa zvakanyatsotsanangurwa kuti chive nechokwadi chekuti system yese yakavimbika.
5. Kubatanidzwa Kwepasi Pose uye Kushandiswa
Simba remitemo yeDIN rinopararira kure kupfuura miganhu yeGermany, uye mitemo yakawanda ichishandiswa senzira dzekutaridza mumapurojekiti epasi rose uye ichibatanidzwa muhurongwa hwemitemo yenyika dzakasiyana-siyana. Kuunganidzwa kwakarongeka kwemitemo yeGerman chain muzvinyorwa zvakaita se "German Chain Drive Standards" neNational Chain Drive Standardization Technical Committee of China (SAC/TC 164) kunoratidza kuti zvirevo izvi zvakaparadzirwa sei pasi rose kuti zvive nyore kuchinjana kwehunyanzvi uye kusangana kwemitemo. Chinyorwa ichi, chine mitemo yeDIN yega yega 51 inosanganisira mhando dzakasiyana dzemaketani dzinosanganisira "multiple plate pin chains", "plate chains", "flat top chains", uye "conveyor chains", chakashanda senzira yakakosha yekutarisa maketani nemasprockets mumaindasitiri epasi rose.
Kukosha kwemitemo yeDIN pasi rose kunoonekwawo nekuwirirana kwayo nezvirongwa zvepasi rose zvekuenzanisa. Mitemo mizhinji yeDIN inoramba ichienderana nemirairo yeISO kuti iite kuti kutengeserana kwenyika dzese nekushandira pamwe chete kwehunyanzvi, uku ichiramba iine zvinodiwa zvehunyanzvi zvakasiyana zvinoratidzira mitemo yeinjiniya yeGerman. Maitiro aya maviri—kuchengetedza zvinodiwa zveDIN zvakananga uku ichikurudzira kuenderana kwenyika dzese—inoita kuti vagadziri vagone kugadzira zvigadzirwa zvinosangana nezvinodiwa zvemusika wedunhu nepasi rose. Mitemo iyi inosanganisira parameters dzehunyanzvi dzemaprofiles emazino esprocket, saizi yekubatanidza, uye specifications yezvinhu zvinoita kuti pave nekushanda pamwe chete pakati pemacheni nemasprocket kubva kuvagadziri vakasiyana pasi rese.
6. Mhedziso
Miyero yeDIN yemaketani esimbi yakatenderera uye zvinobatanidza inomiririra hurongwa hwakazara hwehunyanzvi hwakachinja zvakanyanya kugadzirwa kwecheni yepasi rose uye maitiro ekushandisa. Kuburikidza nemasisitimu ekupatsanura chaiwo, zvinhu zvakaoma uye mashandiro, uye kushanduka-shanduka kunoratidza kufambira mberi kwetekinoroji, zviyero izvi zvakagadzira zviyero zvekuchengetedza, kuvimbika, uye mhando mumashandisirwo akasiyana-siyana emaindasitiri.
