Mu gawo la makina, ma roller chain ndi zinthu zofunika kwambiri potumiza mphamvu pakati pa nkhwangwa zozungulira. Amagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza magalimoto, kupanga ndi ulimi. Ma roller chain amakhala ndi ma links olumikizana omwe amatumiza mphamvu bwino. Komabe, si ma roller chain onse omwe amapangidwa mofanana. M'nkhaniyi, tiwona mozama mitundu yosiyanasiyana ya ma roller chain ndi momwe amagwiritsidwira ntchito.
1. Chingwe cholumikizira chokhazikika:
Maulalo ozungulira okhazikika, omwe amadziwikanso kuti maulalo olumikizira, ndi mtundu wodziwika bwino wa unyolo wozungulira. Maulalo awa ali ndi mbale ziwiri zakunja ndi mbale ziwiri zamkati zokhala ndi ma rollers oyikidwa pakati pawo. Maulalo olumikizira ndiyo njira yayikulu yolumikizira unyolo wozungulira wautali awiri pamodzi, zomwe zimapangitsa kuti ntchito ikhale yosalala. Nthawi zambiri amakhala ofanana ndipo amapezeka mu mawonekedwe amodzi ndi awiri.
2. Maulalo ozungulira a offset:
Ma offset roller link, monga momwe dzinalo likusonyezera, amapangidwira makamaka kuti athetse umodzi mwa ma roller chain. Nthawi zambiri amagwiritsidwa ntchito pa ntchito zomwe zimafuna mphamvu yayikulu kapena torque yayikulu pa chingwe chimodzi cha roller chain. Ma offset link amalola kuti unyolo uziyenda bwino komanso moyenera pa ma sprockets amitundu yosiyanasiyana, zomwe zimathandiza kuti pakhale kusakhazikika kulikonse. Ndikofunikira kudziwa kuti ma offset link ayenera kugwiritsidwa ntchito pa liwiro lotsika komanso katundu wolemera, chifukwa kugwiritsa ntchito kwawo kungachepetse mphamvu yonse komanso kulimba kwa unyolo wa roller.
3. Chiyanjano cha theka:
Chingwe cholumikizira theka, chomwe chimadziwikanso kuti chingwe cholumikizira chimodzi kapena chingwe cholumikizira theka, ndi chingwe chapadera chozungulira chomwe chimakhala ndi mbale yamkati ndi mbale yakunja mbali imodzi yokha. Amalola kusintha kolondola kwa kutalika kwa unyolo ndipo ndi abwino kwambiri pakugwiritsa ntchito komwe kumafuna malo olondola. Zingwe zolumikizira theka zimagwiritsidwa ntchito kwambiri mumakina otumizira, njinga, njinga zamoto ndi ntchito zina pomwe kusintha pang'ono kwa kutalika kwa unyolo ndikofunikira. Komabe, ziyenera kugwiritsidwa ntchito mosamala chifukwa zimayambitsa zofooka zomwe zingachitike mu unyolo.
4. Tsegulani ulalo wa unyolo wozungulira:
Maulalo ogawanika amapereka njira yachikhalidwe yolumikizira maulalo ozungulira pamodzi. Maulalo awa ali ndi mapini ena omwe amalowetsedwa kudzera m'mapepala akunja ndi amkati ndipo amatetezedwa ndi mapini a cotter kapena mapini a cotter. Maulalo otseguka amapereka kukhazikika ndi mphamvu zowonjezera, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito molimbika kwambiri zomwe zimafuna kusamutsa mphamvu zambiri. Komabe, kapangidwe kake kotseguka kamapangitsa kuti zikhale zovuta kuziyika ndi kuchotsa kuposa maulalo olumikizira.
5. Maulalo ozungulira okhala ndi mipata:
Maulalo opindika ndi ofanana ndi maulalo ogawanika, koma gwiritsani ntchito ma rivets m'malo mwa ma cotter pins ngati njira yomangira ma pini. Maulalo opindika amatenga nthawi yochepa kuyika kuposa maulalo ogawanika, koma amataya mwayi wogwiritsidwanso ntchito chifukwa ma rivets sangachotsedwe mosavuta akayikidwa. Nthawi zambiri amagwiritsidwa ntchito pazinthu zomwe zimafuna katundu wolemera pang'ono kapena wochepa monga ma conveyors, makina amafakitale ndi njinga zamoto.
Kumvetsetsa mitundu yosiyanasiyana ya maulalo ozungulira ndikofunikira kwambiri posankha unyolo woyenera wa ntchito inayake. Kaya maulalo olumikizira wamba, maulalo ozungulira, maulalo ozungulira theka, maulalo ogawanika kapena maulalo opindika, ulalo uliwonse uli ndi cholinga chake chomwe chimathandizira kuti unyolo wanu wozungulira ugwire ntchito bwino komanso ukhale wautali. Poganizira zofunikira ndi zofunikira za pulogalamuyi, ulalo woyenera wozungulira ungasankhidwe kuti utsimikizire kuti ukugwira ntchito bwino komanso kudalirika.
