Kusiyana Pakati pa Unyolo Wozungulira wa Single-Pitch ndi Double-Pitch
M'magawo otumizira ndi kutumiza zinthu ndi makina, ma roller chains amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ngati zinthu zotumizira zogwira mtima komanso zodalirika. Ma roller chains okhala ndi ma single pitch ndi ma double-pitch ndi mitundu iwiri yodziwika bwino ya ma roller chains, iliyonse ili ndi mawonekedwe apadera komanso zochitika zogwiritsidwa ntchito. Nkhaniyi ifufuza kusiyana pakati pa mitundu iwiriyi ya ma roller chains kuchokera ku malingaliro osiyanasiyana kuti ithandize ogula apamwamba padziko lonse lapansi kusankha bwino chinthu chomwe chikugwirizana ndi zosowa zawo.
1. Tanthauzo Loyambira ndi Kapangidwe
(I) Unyolo Wozungulira wa Katundu Kamodzi
Unyolo wozungulira wa pitch imodzi umapangidwa ndikupangidwa motsatira pitch yokhazikika. Pitch ndi chimodzi mwazofunikira kwambiri za unyolo, zomwe zimatsimikiza kukula kwake ndi magwiridwe ake. Umakhala ndi maulalo osinthasintha amkati ndi akunja. Maulalo amkati amakhala ndi mbale ziwiri zamkati ndi ma bushing awiri, pomwe maulalo akunja amakhala ndi mbale ziwiri zakunja ndi pini. Ma rollers amakwanira pamwamba pa ma bushing, olumikizidwa ndi pini ndi bushing. Kapangidwe kameneka kamaonetsetsa kuti ma chain ozungulira a pitch imodzi amakhala osinthasintha komanso okhazikika bwino panthawi yogwira ntchito, zomwe zimapangitsa kuti akhale oyenera kugwiritsa ntchito mitundu yosiyanasiyana ya kutumiza ndi kutumiza. (2) Unyolo Wozungulira wa Pitch Double
Unyolo wozungulira wopingasa kawiri ndi unyolo wozungulira wopingasa kamodzi wokhala ndi phokoso lopindika kawiri. Kapangidwe kake kakufanana ndi unyolo wozungulira wopingasa kamodzi, koma ma chain plates ndi aatali kuwirikiza kawiri. Kapangidwe kameneka kamapatsa unyolo wozungulira wopingasa kawiri ubwino wapadera mu ntchito zina.
2. Kusiyana kwa Magwiridwe Antchito
(1) Kulemera kwa katundu
Chifukwa cha kupendekera kwawo kochepa, maunyolo ozungulira okhala ndi pitch imodzi nthawi zambiri amakhala oyenera kugwiritsidwa ntchito pa katundu wopepuka mpaka wapakati. Ngakhale kuti mphamvu zawo zonyamula katundu ndi zochepa, amachita bwino kwambiri pa kutumiza mwachangu komanso molondola. Komabe, maunyolo ozungulira okhala ndi pitch iwiri ali ndi mphamvu zambiri zonyamula katundu chifukwa cha kupendekera kwawo kowonjezereka. Amatha kupirira katundu wambiri ndipo ndi oyenera kutumiza ndi kutumiza katundu wolemera kapena mphamvu yayikulu. Mwachitsanzo, pazida zonyamula katundu zomwe zimafuna kunyamula katundu wolemera pamtunda wautali, maunyolo ozungulira okhala ndi pitch iwiri amatha kukwaniritsa bwino zofunikirazi.
(2) Kugwira Ntchito Mwachangu
Maunyolo ozungulira okhala ndi pitch imodzi nthawi zambiri amapereka mphamvu yotumizira uthenga bwino. Ma pitch awo ang'onoang'ono komanso kapangidwe kake kakang'ono zimathandiza kuti pakhale kulumikizana kolondola ndi sprocket, zomwe zimachepetsa kutaya mphamvu. Ngakhale maunyolo ozungulira okhala ndi pitch iwiri amapereka mphamvu yonyamula katundu wamphamvu, ma pitch awo akuluakulu amatha kusokoneza mphamvu yotumizira mauthenga pamlingo wina. Komabe, m'magwiritsidwe ena komwe mphamvu yotumizira mauthenga siili yofunika kwambiri, maunyolo ozungulira okhala ndi pitch iwiri amaperekabe zabwino zazikulu.
(III) Liwiro Logwira Ntchito
Ma chain a ma roller okhala ndi pitch imodzi ndi oyenera ma transmission othamanga kwambiri. Kapangidwe kake kakang'ono komanso kopepuka kamathandiza kuti ntchito iyende bwino pa liwiro lalikulu. Ma chain a ma roller okhala ndi pitch iwiri ndi oyenera kwambiri pa liwiro lotsika. Komabe, ma chain awo akuluakulu komanso olemera amatha kugwedeza kwambiri komanso phokoso pa liwiro lalikulu. Chifukwa chake, posankha unyolo wozungulira, chisankho pakati pa ma chain a ma roller okhala ndi pitch imodzi ndi awiri chiyenera kutengera zomwe zimafunika pa liwiro la ntchitoyo.
(IV) Moyo Wotumikira
Moyo wa unyolo wozungulira umodzi umakhudzidwa ndi zinthu zosiyanasiyana, kuphatikizapo malo ogwirira ntchito, momwe mafuta amagwirira ntchito, ndi momwe katundu amagwirira ntchito. Pansi pa mikhalidwe yabwino yothira mafuta ndi kukonza, unyolo wozungulira umodzi ukhoza kukhala ndi moyo wautali wautumiki. Chifukwa cha kukula kwawo komanso kapangidwe kolemera, unyolo wozungulira umodzi ukhoza kukhala ndi moyo waufupi wautumiki pansi pa mikhalidwe yofanana yogwirira ntchito. Komabe, kudzera mu kapangidwe kabwino komanso kugwiritsa ntchito zipangizo zapamwamba, moyo wautumiki wa unyolo wozungulira umodzi ukhoza kusinthidwa kwambiri.
3. Zochitika Zogwiritsira Ntchito
(I) Maunyolo Ozungulira a Single-Pitch
Ma chain a single-pitch roller amagwiritsidwa ntchito kwambiri pa ntchito zomwe zimafuna transmission yolondola kwambiri komanso yothamanga kwambiri. Mwachitsanzo, mu njinga, njinga zamoto, ndi zida zazing'ono zopangira makina, ma chain a single-pitch roller amapereka transmission yokhazikika komanso yodalirika. Ndi oyeneranso zida zazing'ono zomwe zimafunikira malo ambiri, chifukwa pitch yawo yaying'ono imalola kuti pakhale njira yotumizira yocheperako.
(II) Maunyolo Ozungulira Awiri
Maunyolo ozungulira awiri amagwiritsidwa ntchito makamaka potumiza katundu wolemera, wothamanga pang'ono komanso wotumizira. Mwachitsanzo, mu makina opangira migodi, makina a zaulimi, ndi zida zazikulu zotumizira, maunyolo ozungulira awiri amatha kupirira katundu wolemera ndikukwaniritsa zofunikira zoyendera mtunda wautali. Ndi oyeneranso kugwiritsa ntchito omwe amafuna kuchuluka kwa mano ozungulira ochepa, chifukwa ma pitch awo akuluakulu amalola kugwiritsidwa ntchito ndi ma sprockets omwe ali ndi mano ochepa.
4. Kukhazikitsa ndi Kusamalira
(I) Kukhazikitsa
Ma chain a ma roller okhala ndi pitch imodzi ndi osavuta kuyika. Chifukwa cha kapangidwe kake kakang'ono komanso kopepuka, kuyika kumafuna kulondola kochepa. Komabe, ma chain a ma roller okhala ndi pitch iwiri amafunika kulondola kwambiri poyika. Chifukwa cha pitch yawo yayikulu komanso kapangidwe kolemera, kulumikizana koyenera kwa unyolo ndi ma sprockets kuyenera kutsimikizika poyika. Kuphatikiza apo, chisamaliro chiyenera kuperekedwa ku kupsinjika kwa unyolo panthawi yoyika kuti tipewe kumasuka kapena kudumpha mano panthawi yogwiritsa ntchito.
(II) Kukonza
Kusamalira unyolo wozungulira umodzi kumayang'ana kwambiri pa kudzola ndi kuyeretsa. Kudzola nthawi zonse kumachepetsa kukangana pakati pa unyolo ndi ma sprockets, zomwe zimapangitsa kuti unyolo ukhale wogwira ntchito nthawi yayitali. Kuphatikiza apo, kuyeretsa unyolo nthawi yake kuchokera ku dothi ndi zinyalala kungalepheretse unyolowo kuti usamamatire kapena kusweka. Unyolo wozungulira wozungulira kawiri umafunikira kusamalidwa mosamala kwambiri. Kuphatikiza pa kudzola ndi kuyeretsa, kuyang'anira kupsinjika kwa unyolo nthawi zonse ndikofunikiranso.
