Nkhani - Kuti mudziwe zambiri zokhudza mayeso a Round Link Chains Breaking Force Test

Kuyesa mphamvu yothyola ndi njira yofunikira komanso yofunikira yowongolera khalidwe la unyolo wozungulira womwe umagwiritsidwa ntchito m'mafakitale ndi ntchito zonyamula. Pepalali likufotokoza njira, kufunika, ndi mfundo zazikulu zochitira mayeso olondola a mphamvu yothyola, poyang'ana kwambiri pazabwino kwambiri.maunyolo okweza (monga, G80, G100), unyolo wa migodi ya malasha, unyolo wa elevator wa ndowa, ndi maunyolo omangirira.Cholinga chake ndikutsimikizira mphamvu ndi kutalika kwake, kuonetsetsa kuti zikutsatira miyezo yapadziko lonse lapansi monga ISO 1834, DIN 5684, ndi ASME B30.9.

Chiyambi

Unyolo wachitsulo wozungulira ndi zinthu zofunika kwambiri pakugwira ntchito, kunyamula, migodi, ndi kugwiritsa ntchito m'madzi. Kulephera kwawo kugwira ntchito kungayambitse ngozi zoopsa, zomwe zimapangitsa kuti kuyesa koopsa kwambiri kukhale kofunika. Kuyesa mphamvu zosweka sikungodziwa kuchuluka kwa katundu womwe unyolo ungathe kupirira usanasweke komanso kumawunikira momwe umatalikira, zomwe zimasonyeza kusinthasintha ndi mtundu wa zinthuzo. Kuyesa kumeneku ndikofunikira kwambiri kuti munthu atsimikizire komanso kuwunika nthawi zonse.

Zipangizo Zoyesera ndi Kukhazikitsa

Makina oyesera mphamvu yothyola amatha kuyendetsedwa molunjika kapena molunjika. Makina opingasa nthawi zambiri amakondedwa pakupanga unyolo wautali, pomwe makina opingasa amatha kukhala ndi zitsanzo zazifupi kapena malo ochepa pansi. Mayesowa amaphatikizapo kutalika kwa chitsanzo chomwe nthawi zambiri chimakhala ndi maulalo 5, 7, kapena kuposerapo, kutengera kutalika kwa unyolo/utali wamkati wa unyolo ndi zofunikira wamba. Unyolowu umamangidwa kumapeto kulikonse ndi maunyolo apadera kapena nsagwada zomangira zomwe zimapangidwa kuti zigwire mwamphamvu mozungulira, kupewa kupindika. Kulinganiza bwino ndikofunikira kwambiri kuti tipewe kulephera msanga kwa zingwezo.

Magawo Oyesera Ofunika

- Liwiro Logwiritsa Ntchito Mphamvu: Katunduyo ayenera kuwonjezeredwa mosalekeza komanso mosalekeza. Miyezo nthawi zambiri imafotokoza kuchuluka kwa kupsinjika (monga 10 MPa/s) kapena liwiro lolamulidwa ndi makina kuti zitsimikizire kuti zotsatira zake zitha kubwerezedwanso. Kukweza mofulumira kwambiri kungayambitse kuwerengera mphamvu kolakwika, pomwe kuthamanga pang'onopang'ono kwambiri kungakhudze momwe zinthu zimayendera.

- Kuyeza: Makinawa amalemba mphamvu ya pamwamba (mphamvu yosweka) ndipo nthawi zambiri kutalika kwake pakasweka. Kutalika kumayesedwa pakati pa mfundo zinazake pa unyolo (nthawi zambiri kumakhala maulalo awiri kapena atatu osiyana) ndipo kumasonyeza kusinthasintha—chinthu chofunikira kwambiri pachitetezo, makamaka ponyamula unyolo.

- Zida Zogwirira: Ma grip ayenera kufanana ndi kukula kwa unyolo ndi mawonekedwe ake kuti apewe kutsetsereka kapena kusokonekera. Pa unyolo wapamwamba monga G80 ndi G100, chisamaliro chimaperekedwa mosamala kuti apewe kuwonongeka kwa pamwamba pa unyolo panthawi yogwirira, zomwe zingakhudze zotsatira.

kuyesa mphamvu yosweka kwa unyolo wozungulira

Kugwiritsa Ntchito Mitundu Yapadera ya Unyolo

- Ma Chain Okweza a G80 ndi G100: Awa ndi ma chain achitsulo olimba kwambiri, omwe amatenthedwa ndi kutentha kuti apeze mphamvu komanso kukana kuwonongeka. G80 ili ndi mphamvu yocheperako yosweka ya 800 MPa, ndi G100 ya 1000 MPa. Kuyesa kumatsimikizira kuti gulu lililonse limakwaniritsa zochepazi, ndipo kutalika nthawi zambiri kumafunika kukhala ≥12% ya G80 ndi ≥10% ya G100.

- Maunyolo Ogwira Ntchito Yokumba Malasha: Maunyolo amenewa amagwiritsidwa ntchito m'ma conveyor ndi zothandizira padenga zoyendetsedwa ndi magetsi, amagwira ntchito m'malo ovuta kwambiri komanso ovuta kwambiri. Mayeso ophwanya mphamvu amaonetsetsa kuti amatha kupirira mphamvu zonyamula katundu ndi kugwedezeka pansi pa nthaka.

- Ma Chain Elevator a Chidebe: Ma Chain awa amagwira ntchito ndi zinthu zambiri; mayesowa amatsimikizira kukana kutopa ndi mphamvu pamene akunyamula zinthu mosalekeza, nthawi zambiri ndi cholinga chowonjezera kutalika kuti apewe kusweka.

- Maunyolo Omangirira (Maunyolo Omangirira): Ogwiritsidwa ntchito poteteza katundu, ayenera kukwaniritsa magiredi enaake (monga Giredi 8, Giredi 10). Mayeso ophwanya mphamvu amatsimikiza malire a katundu wogwirira ntchito ndi zinthu zotetezera, nthawi zambiri 4:1 kapena kupitirira apo.

Kufunika kwa Kuyesa Kolondola

Deta yodalirika ya mphamvu yothyola imatsimikizira kuti maunyolo amagwira ntchito bwino motsatira malire a ntchito yawo. Kuthamanga kosasinthasintha, kukanikiza kosayenera, kapena kuyeza kolakwika kungayambitse kulephera kapena kulephera kwachinyengo, zomwe zingawononge chitetezo ndikupangitsa kuti munthu akhale ndi mlandu. Kuyang'anira makina oyesera nthawi zonse ndikutsatira njira zolembedwa ndikofunikira poyesa ovomerezeka.

Kuyesa mphamvu yophwanya malamulo akadali njira yeniyeni yotsimikizira umphumphu wa unyolo wozungulira. Kwa opanga ndi ogwiritsa ntchito unyolo wokweza wa G80/G100, unyolo wopangira migodi, unyolo wokwezera, ndi unyolo womangirira, kutsatira mosamalitsa njira zoyesera zokhazikika kumatsimikizira kuti unyolo umakwaniritsa zofunikira za mphamvu ndi kusinthasintha. Kuyika ndalama mu zida zoyesera zolondola ndi ntchito yophunzitsidwa sikungokwaniritsa zofunikira zolamulira komanso kumasunga miyezo yapamwamba kwambiri yachitetezo pantchito zamafakitale.

Kutalikirana kwa unyolo wa unyolo panthawi yoyesa mphamvu yosweka ndi muyeso wofunikira wa ubwino wake, womwe umavumbula zambiri osati mphamvu yeniyeni. Umagwira ntchito ngati chizindikiro chachikulu cha kusinthasintha kwa zinthu, kusinthasintha kwa kapangidwe kake, komanso kulimba kwa kapangidwe kake konse.

Njira Zoyezera Kutalika

Kutalika kumayesedwa ngati kuwonjezeka kosatha kwa kutalika kwa unyolo pambuyo poti wasweka, komwe kumawonetsedwa ngati peresenti ya kutalika koyambirira. Pali njira ziwiri zazikulu zoyezera:

i) Kuyesa Kuwononga M'malo Opangira Zinthu (Panthawi Yopanga & Satifiketi)

Iyi ndiyo njira yoyamba yowongolera khalidwe lomaliza ndi kuvomereza mtundu.

Utali wokhazikika wa unyolo (monga maulalo 5 kapena 7) umayikidwa mu makina oyesera omangika. Sensor yosinthira ya laser kapena extensometer imayesa bwino mtunda pakati pa mfundo ziwiri zolembedwa pa unyolo pamene mphamvu ikugwiritsidwa ntchito pakuwononga.

Imajambula kutalika konse (kwa pulasitiki) pa mphamvu yosweka, zomwe zimapereka phindu lenileni la chitsimikizo cha khalidwe. Makina apamwamba amapanga mzere wathunthu wa mphamvu-kutalika, womwe umasonyeza magawo onse awiri otanuka komanso osinthika a pulasitiki.

ii) Kuyeza M'munda ndi Munjira (Kuyang'anira ndi Kukonza)

Njira zosawononga izi zimayesa kutalika kwa njira yogwiritsira ntchito kuti zidziwike kulephera.

Njira Yowunikira Zithunzi: Chithunzi cha maulalo a unyolo chimasanthulidwa. Dongosololi limawerengera ma pitch osiyanasiyana (kutalika) kwa maulalo amkati ndi akunja. Kuwonongeka ndi kutalikika kumachitika makamaka m'maulalo amkati; kutalikikako kumawerengedwa poyerekeza kukwera kwa kumtunda kwa kumtunda kwa kumtunda kwa kumtunda ndi kumtunda kwa kumtunda kwa kumtunda kokhazikika.

Njira Yowerengera Ma pulse a Chizindikiro: Imagwiritsidwa ntchito poyendetsa maunyolo mosalekeza. Masensa awiri amayikidwa mtunda wokhazikika. Chizindikiro pa ulalo umodzi chimadutsa sensa yoyamba, kuyambitsa kauntala yomwe imawerengera ma pulse kuchokera ku zizindikiro pa maunyolo otsatira mpaka chizindikiro choyambirira chidutsa sensa yachiwiri. Kuchuluka kwa kuwerengera kumasonyeza kuti unyolowo watambasuka.

Pa maunyolo Okwezera Apamwamba (monga G80, G100), kutalikitsa ndi chipata chabwino kwambiri:

Ma Chains a G80: Kutalikirana kochepa kwambiri panthawi yopuma nthawi zambiri kumakhala 15%.

Ma Chains a G100: Kutalikirana kochepa kwambiri panthawi yopuma nthawi zambiri kumakhala 12%.

Kuchuluka kwa mphamvu kumeneku kumatsimikizira kulimba kwapadera komanso kuyamwa mphamvu. Unyolo womwe umakumana ndi mphamvu yosweka koma wochepa kutalika kwake ndi wofooka ndipo ukhoza kulephera mwadzidzidzi chifukwa cha kugwedezeka—chiwopsezo chachikulu cha chitetezo.

Pa ntchito monga migodi ya malasha kapena ma elevator a mabaketi, kusanthula kutalika kwa ma chain links ndi njira yodziwira:

Chiwerengero cha Zolinga: Kutalika kovomerezeka nthawi zambiri kumakhala pakati pa 10% ndi 15%.

Kutalikirana Kwambiri (<10%) kumasonyeza mavuto okhudzana ndi zinthu kapena kutentha, zomwe zimapangitsa kuti pakhale kusweka kwa mafupa. Kafukufuku wokhudza unyolo wa migodi akusonyeza kuti kutalikirana kosauka nthawi zambiri kumagwirizana ndi njira zosafunikira zosweka pamalo olumikizirana, malo ofooka kwambiri.

Kutalikirana kwambiri (>18-20%) kungasonyeze kuti zinthuzo ndi zofewa kapena kuti sizili zolimba mokwanira, zomwe zingalepheretse kutopa komanso kulola kuti unyolowo uwonongeke kwambiri ("kukula") pansi pa katundu wabwinobwino, zomwe zimayambitsa mavuto monga kusagwira bwino ntchito ndi ma sprockets.
