Makhalidwe a unyolo wozungulira ndi maulalo olumikizira

1. Kapangidwe ka unyolo wozungulira
Unyolo wozungulira ndi mtundu wa unyolo womwe umagwiritsidwa ntchito kwambiri potumiza zinthu ndi makina. Kapangidwe kake ndi motere:
(I) Zopangira zoyambira
Unyolo wozungulira umakhala ndi mbale zolumikizira zamkati, mbale zolumikizira zakunja, mapini, manja ndi ma rollers. Ma rollers ndi manja amkati, mbale zolumikizira zakunja ndi ma pin ndi oyenera kusokoneza, pomwe ma rollers ndi manja, ndi manja ndi ma pin ndi oyenera. Kuyenerera kumeneku kumalola unyolo kuzungulira mosinthasintha panthawi yogwira ntchito pamene ukusunga kukhazikika kwa kapangidwe kake.
(II) Kapangidwe ka mbale ya unyolo
Ma plate a unyolo wa ma roller nthawi zambiri amapangidwa mu mawonekedwe a "8". Kapangidwe kameneka kangapangitse mphamvu yokoka ya gawo lililonse la unyolo kukhala yofanana, pomwe kuchepetsa kulemera kwa unyolo ndi mphamvu yosagwira ntchito panthawi yoyenda.
(III) Kukweza mawu
Kupindika kwa unyolo wozungulira ndi chimodzi mwa zinthu zofunika kwambiri. Kupindika kwakukulu, kukula kwa gawo lililonse la unyolo kumakulirakulira komanso mphamvu yonyamula katundu imakwera. Kukula kwa pilo kumakhudza mwachindunji magwiridwe antchito a unyolo ndi moyo wautumiki.
(IV) Unyolo wa mizere yambiri
Kuti akwaniritse zofunikira zazikulu zonyamula katundu, ma roll chain amatha kupangidwa ngati ma roll chain a mizere yambiri. Ma roll chain a mizere yambiri amalumikizidwa ndi ma pin ataliatali, ndipo mphamvu yawo yonyamula katundu imafanana ndi kuchuluka kwa mizere. Komabe, mizere yambiri imabweretsa zofunikira kwambiri popanga ndi kukhazikitsa molondola, ndipo n'kovuta kutsimikizira kufanana kwa mphamvu pamzere uliwonse, kotero chiwerengero cha mizere sichiyenera kukhala chochuluka kwambiri.

2. Makhalidwe a kapangidwe ka maulalo olumikizira
Chingwe cholumikizira ndi gawo lofunika kwambiri la unyolo wozungulira, womwe umagwiritsidwa ntchito kulumikiza malekezero awiri a unyolo kuti upange unyolo wotsekedwa. Makhalidwe a kapangidwe ka chingwe cholumikizira ndi awa:
(I) Njira yolumikizira
Kawirikawiri pali mitundu iwiri ya maulalo olumikizira: kugawanika kwa ma pin ndi ma spring card. Kugawanika kwa ma pin ndi koyenera ma pitch chain akuluakulu, pomwe ma spring card ndi koyenera ma pitch chain ang'onoang'ono.
(II) Ulalo wosinthira
Ngati chiwerengero chonse cha maulalo mu unyolo ndi nambala yosamvetseka, ulalo wosinthira umafunika kuti ulumikizidwe. Chingwe cha unyolo cha unyolo wosinthira chidzapanga nthawi yowonjezera yopindika ikakokedwa, kotero mphamvu yake imakhala yotsika kuposa ya ulalo wamba. Pofuna kupewa kugwiritsa ntchito maulalo osinthira, chiwerengero cha maulalo mu unyolo chiyenera kukhala chofanana momwe zingathere popanga.
(III) Ulalo wosinthira wa gulu
Chingwe chosinthira chophatikizana ndi chingwe chosinthira chokonzedwa bwino chokhala ndi kapangidwe kovuta kwambiri kuposa chingwe chosinthira wamba, koma chokhala ndi magwiridwe antchito abwino. Chingwe chosinthira chophatikizana chimatha kunyamula bwino katundu ndikuchepetsa mphamvu ya mphindi yowonjezera yopindika.

3. Kugwirizana kwa unyolo wozungulira ndi ulalo wolumikizira
Kugwirizana kwa unyolo wozungulira ndi ulalo wolumikizira ndiye chinsinsi chotsimikizira kuti kutumiza kwa unyolo kukuyenda bwino. Pakupanga ndi kugwiritsa ntchito, mfundo zotsatirazi ziyenera kukumbukiridwa:
(I) Utali wa unyolo
Kutalika kwa unyolo nthawi zambiri kumafotokozedwa mu chiwerengero cha maulalo. Nthawi zambiri, chiwerengero chofanana cha maulalo chimasankhidwa kuti chikhazikitsidwe ndi pini ya cotter kapena khadi la spring. Ngati chiwerengero cha maulalo ndi nambala yosamvetseka, ulalo wosinthira uyenera kugwiritsidwa ntchito.
(II) Mafuta odzola
Pofuna kuchepetsa kuwonongeka pakati pa pini ndi chikwama, unyolo wozungulira uyenera kupakidwa mafuta panthawi yogwira ntchito. Mafuta abwino amatha kukulitsa nthawi yogwira ntchito ya unyolo ndikuwonjezera mphamvu yotumizira.
(III) Kukonza
Yang'anani nthawi zonse kutha kwa unyolo ndipo sinthani maulalo owonongeka kwambiri pakapita nthawi. Nthawi yomweyo, samalani ndi kupsinjika kwa unyolo kuti muwonetsetse kuti unyolowo sudzamasuka kapena kulumpha mano panthawi yogwira ntchito.

4. Kugwiritsa Ntchito ndi Ubwino
(I) Munda Wofunsira
Ma roller chain amagwiritsidwa ntchito kwambiri potumiza zinthu m'mafakitale osiyanasiyana monga ulimi, migodi, zitsulo, petrochemicals, ndi kunyamula ndi mayendedwe. Mphamvu yake yotumizira zinthu imatha kufika 3600kW, liwiro la unyolo lingafike 30 ~ 40m/s, ndipo chiŵerengero chachikulu cha kutumiza zinthu chimafika 15.
(II) Ubwino
Kuchita bwino kwambiri: Mphamvu yotumizira ma roller chain ndi yapamwamba, nthawi zambiri mpaka 96% ~ 97%.
Kulemera kwakukulu: Ma roll unyolo amatha kupirira katundu waukulu ndipo ndi oyenera kutumiza katundu wolemera.
Kusinthasintha kwamphamvu: Ma roll unyolo amatha kugwira ntchito m'malo ovuta monga kutentha kwambiri, fumbi, ndi chinyezi.
Kapangidwe kakang'ono: Kapangidwe ka roller chain transmission ndi kakang'ono ndipo kamatenga malo ochepa.

5. Mapeto
Makhalidwe a unyolo wozungulira ndi maulalo olumikizirana nawo amawapangitsa kuti azigwiritsidwa ntchito kwambiri ndipo ali ndi ubwino waukulu pakutumiza kwa makina. Kudzera mu kapangidwe ndi kukonza koyenera, unyolo wozungulira ukhoza kupeza kutumiza kogwira mtima komanso kodalirika kuti kukwaniritse zosowa za mafakitale osiyanasiyana.
