TL;DR — Zvinhu Zvinokosha Zvaunofanira Kuziva
- Mavhiri echeni eDIN 766 (short-link) neDIN 764 (long-link) haashande pamwe chete — pocket pitch inosiyana neinenge 33% uye kuisa cheni isiriyo kunokonzera kukurumidza kupera kwe sprocket, kusunga cheni, uye kusvetuka kwecheni pasi pemutoro.
- Kuomarara kwezvinhu zvevhiri rechain zveHRC 45-50 zvine mativi emazino akaomarara einduction ndiko kunonyanya kutsanangurwa kwekushandisa winch yeanchor yegungwa.— zvinhu zvakapfava (zviri pasi peHRC 40) zvinoratidza kusakara kwemuhomwe kunoyerwa mushure menguva dze500-800 munzvimbo dzinopfapfaidzwa nemunyu.
- Mavhiri echeni eISO 16726 anoenderana neDIN 766 pahukuru hwemadhayamita akafanana echeni (13mm-26mm), asi chiyero cheISO chinotsanangura kushivirira kwepocket kwakasimba (+0.3mm vs DIN's +0.5mm)— zvichireva kuti vhiri rakayerwa neISO rinoshanda neketani yeDIN, asi vhiri reDIN rinogona kusasangana nezvinodiwa neISO tolerance.
Nei "Standard Chain Wheel" Isiri Yese Yakakosha - Maitiro Matatu Anokwikwidzana
Ndapedza makore gumi nemashanu ndichigadzira masisitimu e hydraulic winch kuYining Hydraulic, uye chikanganiso chimwe chete chinodhura zvikuru chandinosangana nacho pakutenga anchor winch ifungidziro yekuti "standard chain wheel" zvinoreva chinhu chimwe chete kune vese vagadziri.Kune mitemo mikuru mitatu yecheni iri kushandiswa pasi rose — DIN 766, DIN 764, uye ISO 16726/ISO 67 — uye vhiri recheni rakagadzirirwa imwe standard harizoshande zvakachengeteka necheni kubva kune imwe standard.Misiyano yacho haisi yekushongedza: inosanganisira pocket pitch, root diameter, tooth profile angle, uye chiyero chechain dayameter nepitch chinosarudza kuti chain link inogara sei muhomwe yevhiri.
DIN 766 ndiyo nzira yekubatanidza zvidimbu zvipfupi yakatanga kugadzirwa kuti ishandiswe pakusimudza zvidimbu uye mugungwa. Iyo nzira yekutsanangura: pitch yakaenzana nedhayamita yecheni ka6 (6d). Iyi nzvimbo yekubatanidza zvidimbu zvidiki inowedzera nzvimbo yekubatana kwecheni nevhiri, ichigovera mutoro pakati pemazino akawanda uye ichideredza kushushikana kwezino rega rega. DIN 764 ndiyo nzira yekubatanidza zvidimbu zvirefu apo pitch yakaenzana nedhayamita yecheni ka8 (8d). Nzvimbo yakareba yekubatanidza zvidimbu inoderedza huremu hwecheni pamita imwe neimwe uye inobvumira cheni yakakura yedhayamita kutenderedza mavhiri akamanikana. ISO 16726 (uye ISO 67 yakabatana yecheni dzekusungira) inoedza kubatanidza zviyero izvi pasi rese asi inounza misiyano midiki inokanganisa kuenderana.
Mhedzisiro inoshanda yekusanganisa zviyero: kana ukaisa cheni yeDIN 766 pavhiri reDIN 764 (kana zvinopesana), macheni acho haazogari zvakakwana muhomwe dzevhiri.Malink acho anotenderera pamipendero yehomwe kwete pasi pehomwe, achiisa mutoro pamutsetse panzvimbo pekubata pamusoro. Mugumisiro wacho unokurumidza kupera mupendero wehomwe, kuchinja kweketani, uye muzviitiko zvakakomba, kusvetuka kwecheni uko cheni inokwira kubva muhomwe iri pasi pemutoro. Ini pachangu ndakabata ongororo yewarandi apo chikonzero chikuru chekukundikana kwevhiri recheni kwaive cheni yeDIN 764 yakatengwa nemushandi wengarava kuti itsive cheni yeDIN 766 yakasakara nekuti "dhayamita yacho yaitaridzika zvakafanana." Sekureva kwaMagwaro emitemo yeDIN, kunyangwe cheni dzine dhayamita yakafanana (semuenzaniso, 16mm) kubva pamatanho akasiyana dzine zvinodiwa zvakasiyana zvejometri yepocket.
Zvinokosha zveGeometry yeChain Wheel: Dhayamita yePitch, Dhayamita yeKunze, uye Dhayamita yeMudzi
Vhiri recheni (rinonziwo wildcat kana kuti chain sprocket) rinotsanangurwa nemadhayamita matatu akakosha: dhayamita yepitch (Dp), dhayamita yekunze (Da), uye dhayamita yemidzi (Df).Dhayamita yepitch ndiyo dhayamita yedenderedzwa redzidziso iro macheni anobatanidza pariri paanotenderera vhiri — ndiyo dhayamita inoshanda inosarudza kumhanya kwecheni kwevhiri rakapihwa RPM. Dhayamita yekunze inoyerwa pamusoro pemazino uye ndiyo dhayamita yakakura kwazvo yevhiri. Dhayamita yemidzi inoyerwa pasi pehomwe dziri pakati pemazino.Dhayamita yepitch inoverengwa seDp = P / sin(180/Z), apo P iri cheni pitch (link spacing) uye Z iri nhamba yehomwe (mazino) dziri pavhiri.Kune cheni yeDIN 766 ine dhayamita ye16mm uye chiyero chepitch che6:1, pitch yacho i96mm, uye vhiri rine pocket 5 rine Dp = 96mm / sin(36 degrees) = 163.5mm.
Homwe yacho pachayo ine mativi matatu akakosha: upamhi hwehomwe (inofanira kuenderana nehupamhi hweketani pamwe nehupamhi hwe 0.5-1.5mm hwekumhanya), kudzika kwehomwe (inofanira kuenderana nehupamhi hweketani pamwe ne 1-2mm kuti ibvise marara), uye kona yepocket pitch (inofanira kuenderana nekona yeketani chaiyo kudzivirira kusawirirana kwelink-to-pocket).Kushivirira upamhi hwepocket ndicho chinhu chakakosha zvikuru — chain yacho inobatirira zvakanyanya panguva yekubata; yakasununguka zvakanyanya uye cheni yacho inotenderera, zvichikonzera kupera kwemazino kusina kuenzana.Kukwanisa kushivirira upamhi hwepocket wheels dzemarine anchor winch kuri pakati pe +0.3mm kusvika +0.8mm pamusoro pe nominal chain link width.
Magadzirirwo eDIN 766 Chain: Short-Link Standard Inoshandiswa muEuropean Marine Applications
DIN 766 ndiyo chiyero chikuru chezvihwini zvegungwa zvekutanga kuEurope uye zvihwini zveYining Hydraulic zvechihwini zvakagadzirwa zvinoenderana nemisika yeEurope neMiddle East.Mutemo unotsanangura hukama huripo pakati pedhayamita yecheni (d) nehukuru hwekubatanidza: pitch (t) = 6d, upamhi hwemukati (b1) = 3.5d yehukuru hwecheni dzegungwa dzakajairika. Kune cheni ye16mm DIN 766: pitch = 96mm, upamhi hwemukati = 56mm, urefu hwemukati = 80mm. Kushivirira papitch ndeye +0.033d - zvichireva kuti kune cheni ye16mm, kushivirira kwepitch ndeye +0.53mm palink.
Kugadzirwa kwemavhiri echeni eDIN 766 kunoda homwe inokwana link profile yese: homwe yakatambanudzwa inogara muhomwe ine axis yayo refu yakabatana ne wheel axis, nepo vertical link (inobatanidza horizontal links dziri pedyo) ichipfuura nepakati pemazino.Dhizaini yemazino inofanira kupa mukana wakakwana kuti chinongedzo chakamira chipinde nekubuda muhomwe pasina kukanganiswa sezvo vhiri richitenderera.Yining Hydraulic, mawinji edu eIYM series anchor akagadzirwa neDIN 766 pocket geometry senzira yekutanga, neDIN 764 neISO pocket geometry dziripo sesarudzo dzakatarwa. Vhiri recheni rakagadzirwa kubva kusimbi ye42CrMo alloy, rinodzimwa uye rinonamirwa kuHRC 45-50, nemativi emazino akaomarara kuHRC 55-58 kuti arambe kupera.
Magadzirirwo eDIN 764 Chain: Muyero weLong-Link weZvishandiso zveHigh-Chain Diameter
DIN 764 inotsanangura chiyero che pitch-to-diameter chakareba (8d) zvichienzaniswa neDIN 766 (6d), ichigadzira cheni dzakareba ne33% pachisungo chimwe nechimwe chedhayamita imwe chete yecheni.Iyi pitch yakareba ine zvinangwa zviviri: inoderedza huremu hwecheni pamita (zvisungo zvishoma pamita zvinoreva huremu hushoma hwesimbi), uye inobvumira cheni kutenderedza mavhiri madiki-radius (link refu rinogona kutenderera pamusoro pekongiri yakamanikana pasina kusunga). Kune mashandisirwo apo winch yeanchor inofanira kubata cheni yakakura-dhayamita (20mm+) asi ngarava ine nzvimbo shoma yemusango, geometry yeDIN 764 yepitch refu ndiyo sarudzo inosarudzwa.
Maitiro eDIN 764 chain wheel pocket akasiyana zvachose neDIN 766: pocket yacho yakareba (kuti ikwane link refu), yakadzika (nekuti link angle inopinda muhomwe haina kunyanya kuoma), uye zino racho rakavhurika zvakanyanya kuti link refu yakamira ibude pachena.Musungo wekutenga zvinhu wakajairika: Vagadziri vekuChina dzimwe nguva vanotaura "DIN standard chain wheel" vasina kutaura 766 kana 764, vachifunga kuti mutengi anoda mari yekutenga yemuno (inowanzova DIN 764 mumusika wekuChina).Mutengi anogamuchira vhiri reDIN 764 recheni yavo yeDIN 766 pamwe nenzvimbo dzisingaenderane panguva yekuisa. Ndinokurudzira zvikuru kuti utaure chiyero chaicho uye dhayamita yecheni paodha yekutenga, kwete kuvimba neshoko rekuti "standard."ISO 16726:2018Zvinodiwa pakushandisa vhiri recheni, chiyero ichi chinoda kunyorwa zvakajeka kwechiyero checheni nedhayamita pavhiri pacharo.
