Bakelite, yemwe amadziwikanso kuti Bakelite, ndiye chinthu chosankhidwa pamakina, mawilo am'manja. Pankhani ya magudumu am'manja, aliyense sangakhale wachilendo. Titha kuziwona m'mafakitale ambiri. Mawilo am'manja amabwera mumitundu yosiyanasiyana. Pamwamba pa mankhwalawa ndi opukutidwa komanso okongola kwambiri. Ngakhale kuti ndi chowonjezera chaching'ono chomakina, mpikisano wamakina owonjezera ndi wowopsa kwambiri. Palinso mavuto ena mu chitukuko chamakono. Zifukwa zazikulu ndi mbali zotsatirazi. Bwerani mudzawone ndi mkonzi.
1. Chifukwa cha kusokonekera kwachuma m'zaka zaposachedwa, makampani opanga makina atsika kwambiri, ndipo kutulutsa kwa{1}}makina akulu kwayamba kuchepa. Chodabwitsa ichi chapangitsa kuti othandizira ake opanga ma wheel wheel nawonso akhudzidwe kwambiri.
2. Malo opangira makina a handwheel ndi otsika, ndipo kupanga sikufuna ndalama zambiri, ndipo teknoloji yopangira makina a handwheel ndi yosavuta, choncho pali zinthu zambiri zochulukitsa.
3. Pofuna kukopa ogwiritsa ntchito ambiri, opanga magudumu am'manja ambiri adayamba kuthamangira kuti achepetse mitengo, zomwe zidapangitsa kuti phindu la malo opangirako lichepe komanso kuti phindu lachuma lichepe. Kuphatikiza apo, kutsika kwamitengo kwakhungu koteroko sikothandiza kukonzanso, kufufuza ndi chitukuko ndi kusintha kwa kupanga kwa zinthu zapamanja. Ambiri mwa opanga ma wheel wheel amatha kukhalabe ndi momwe zinthu ziliri, muzochitika zopanda pake, zimakhala zovuta kuyambitsa zopambana zatsopano.
Mfundo zitatu zomwe tatchulazi ndi momwe mawilo amagwirira ntchito pamakina am'makina. Ngakhale pali mavuto ndi zovuta zambiri, mawilo am'manja akulonjezabe. Chifukwa dziko lonse lalowa m'nthawi yotukuka mwachangu-mafakitale akulu, ndipo bizinesi yayikulu yamakampani ndi kupanga makina. Anthu ena amanena kuti kupanga makina ndi njira yopititsira patsogolo chitukuko cha anthu, ndipo makampani opanga makina ndi njira yopititsira patsogolo chikhalidwe cha anthu. Chifukwa chake, makampani opanga ma handwheel akuyenera kuyenderana ndi mayendedwe a chitukuko chachuma ndikukhala ndi zomwe akwaniritsa pakuwonongeka.
Mayendedwe a chitukuko cha handwheel
1. Kupulumutsa mphamvu ndi kuteteza chilengedwe
Kukula kwa magudumu am'manja kuyenera kupita ku chitukuko chokhazikika. Pankhani ya zida zopangira, opanga ma wheel wheel ayenera kugwiritsa ntchito mapulasitiki a phenolic obiriwira komanso okonda zachilengedwe. Izi sizingotsegula msika wopulumutsa mphamvu-, komanso kuchepetsa kwambiri kuwononga chilengedwe, potero zisungitse chitukuko chokhazikika chachuma chamakampani opanga zinthu zamanja.
2. Kupanga koyenera
Mawilo am'manja amagwiritsidwa ntchito kwambiri mumakampani opanga makina ndipo amaphatikiza magawo osiyanasiyana azachuma chadziko. Mosasamala kanthu za momwe chuma chilili, mawilo amanja,{1}}zazambiri zamakina, sizizimiririka pamaso pa anthu. Komabe, opanga magudumu am'manja ayenera kutengera mtundu wazinthu ngati poyambira, kulabadira kupanga mawilo am'manja, ndikuwonjezeranso mapangidwe amunthu. Mwachitsanzo, zida zama wheel wheel zomwe zimagwiritsidwa ntchito pa ma crane ziyenera kuganizira momwe dzanja la munthu limapangidwira, komanso kusamuka pakati pa ndodo ya crane ndi gudumu la m'manja kuyenera kulumikizidwa kuti zikhale zosavuta komanso zogwira ntchito{4}}kupulumutsa momwe kungathekere.
