Maulalo Ozungulira a Roller Chain Closed-Loop: N’chifukwa Chiyani Maulalo Ofanana Ndi Oyenera?

Maulalo Ozungulira a Roller Chain Closed-Loop: N’chifukwa Chiyani Maulalo Ofanana Ndi Oyenera?

Mu makina otumizira magetsi m'mafakitale, maunyolo ozungulira, monga zida zotumizira magetsi zogwira ntchito bwino komanso zodalirika, amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, kuphatikiza kupanga makina, zida zaulimi, ndi zinthu zina. Kwa ogula, kusankha unyolo wozungulira wokhala ndi magawo oyenera kumakhudza mwachindunji magwiridwe antchito a zida, ndalama zosamalira, komanso nthawi yogwirira ntchito. Ngakhale kusankha chiwerengero chonse cha maunyolo mu unyolo wotsekedwa kungawoneke ngati kosavuta, kumakhala ndi mfundo zofunika kwambiri zaukadaulo. Mgwirizano wamakampani umati maunyolo ofanana ndi omwe amakondedwa pa unyolo wozungulira. Lingaliro ili si lopanda pake; limachokera pa kuganizira kwathunthu za kapangidwe ka unyolo, magwiridwe antchito a unyolo, ndi nthawi yogwirira ntchito.

I. Kapangidwe ndi Mfundo Zoyambira za Unyolo Wozungulira
Kuti mumvetse mfundo yaikulu yomwe imayang'ana kusankha maulalo, choyamba ndikofunikira kumvetsetsa kapangidwe kake ka unyolo wozungulira. Unyolo wozungulira wokhazikika umakhala ndi mbale zamkati ndi zakunja, mapini, mabushing, ndi ma rollers. Mapini ndi mabushing amalumikizana kuti azitha kuzungulira mosinthasintha kwa maulalo oyandikana nawo. Unyolo ukapanga lupu yotsekedwa, maulalo olumikizira amafunika kuti ateteze malekezero. Pali njira ziwiri zolumikizirana:

Maulalo olumikizira wamba (a maulalo okhala ndi manambala ofanana okha)

Chopangidwa ndi mbale yakunja yolumikizira, mbale yamkati yolumikizira, ndi pini, piniyo imatetezedwa ndi kachidutswa ka spring clip kapena pini ya cotter. Kapangidwe kake ndi kofanana ndi ka chigwirizano chokhazikika ndipo chimagwira ntchito ngati potseka pokhapokha pomanga.

Maulalo osinthira (a maulalo olembedwa manambala osamveka okha)

Ngati chiwerengero chonse cha maulalo chili chosamvetseka, maulalo osinthira amafunika. Maulalo awa ali ndi mbale yolumikizira yakunja yomwe imapindika kwambiri, yomwe imafuna kulumikizana nthawi imodzi pakati pa maulalo amkati ndi akunja. Izi zimapangitsa kuti pakhale zovuta zosiyanasiyana kuposa maulalo wamba.

II. Ubwino Waukulu wa Ma Chain a Nambala Yofanana: Kuchokera pa Kuchita Bwino kwa Makina mpaka Kufunika Kothandiza
1. Kupewa Maulalo Osinthira, Kukweza Mphamvu Zonse
Maulalo osinthira ndi chinthu chofunikira kwambiri pa unyolo wa manambala osamvetseka, koma ali ndi zovuta zazikulu pa kapangidwe kake:
Ma link akunja a transition links ayenera kupirira kupindika, pomwe ma link achikhalidwe amangopirira kupindika. Izi zimapangitsa kuti ma transition links akhale ofooka ndi 15%-20% kuposa ma link wamba.
Pakakhala liwiro lalikulu kapena katundu wolemera, maulalo osinthira amatha kukhala ofooka mosavuta. Pakapita nthawi, amatha kusweka kapena kusweka, zomwe zimapangitsa kuti zida zisagwire ntchito kapena ngozi.
Kugwiritsa ntchito unyolo wa manambala ofanana kumachotsa kwathunthu maulalo osinthira, kuonetsetsa kuti katundu amagawidwa mofanana pa maulalo onse, zomwe zimapangitsa kuti unyolowo uzitha kunyamula katundu komanso kukana kutopa.
2. Kuchepa kwa Kugwedezeka kwa Ma Transmission ndi Kuchepa kwa Kuvala
Pa nthawi yotumizira mauthenga, ma roll chain amakumana ndi kugwedezeka nthawi ndi nthawi akamalumikizana pakati pa ma chain links ndi mano a sprocket. Malo olumikizirana a ma chain links okhala ndi manambala ofanana amagwirizana ndi kapangidwe ka unyolo wamba, zomwe zimapangitsa kuti pakhale kufalikira kofanana kwambiri panthawi yolumikiza ma mesh. Komabe, ma transition links opangidwa mosiyanasiyana amatha kupangitsa kuti ma mesh awonongeke, zomwe zimapangitsa kuti ma rollers, bushings, ndi mano a sprocket awonongeke, zomwe zimapangitsa kuti unyolo ndi sprocket zisamagwire ntchito bwino.
3. Kukhazikitsa ndi Kusamalira Kosavuta, Kuchepetsa Ndalama
Maulalo a unyolo okhala ndi manambala ofanana ndi osavuta kulumikiza ndi kugwiritsa ntchito. Maulalo olumikizira wamba amatha kuyikidwa ndikuchotsedwa mwachangu pogwiritsa ntchito zida wamba, zomwe zimapangitsa kuti pasakhale kufunikira kwa njira zapadera.
Maulalo osinthira amafunika kulinganizidwa bwino panthawi yokhazikitsa, apo ayi angapangitse kuti unyolo upatuke mosavuta ndikuwonjezera zovuta zosamalira.
Kuchokera pamalingaliro a nthawi yayitali, maulalo a unyolo okhala ndi manambala ofanana amakhala ndi chiwopsezo chochepa cha kulephera komanso nthawi yayitali yosinthira, zomwe zimachepetsa nthawi yogwira ntchito kwa zida ndi kugwiritsa ntchito zida zina, zomwe zimachepetsa ndalama zonse kwa wogula.
4. Imagwirizana ndi ma sprockets okhazikika, zomwe zimapangitsa kuti ntchito yotumizira igwire bwino ntchito
Ma sprockets a mafakitale nthawi zambiri amapangidwa ndi mano ofanana kapena osamvetseka, koma ma meshing frequency a sprocket ndi unyolo ayenera kufanana kuti apewe kumveka bwino. Ma unyolo okhala ndi ma link ofanana amapereka meshing cycle yokhazikika yokhala ndi ma sprockets, kuchepetsa kusinthasintha kwa liwiro komwe kumachitika chifukwa cha ma link osagwirizana ndi mano a sprocket, ndikuwonjezera magwiridwe antchito a transmission ndi 3%-5%. Ndi oyenera kwambiri zida zomwe zimafuna kulondola kwa liwiro (monga mizere yolumikizira yolondola ndi makina osindikizira).

III. Zofunikira pakugwiritsa ntchito
Kulinganiza Chiwerengero cha Maulalo ndi Mtunda wa Pakati
Mukasankha unyolo wokhala ndi maulalo ofanana, ganizirani mtunda wa pakati pa chipangizocho. Ngati mtunda wa pakati ndi wokhazikika, sinthani chiwerengero cha maulalo (manambala ofanana omwe mumakonda) kuti muwonetsetse kuti unyolo uli ndi mphamvu yokwanira. Ngati chiwerengero cha maulalo chiyenera kufanana bwino ndi mtunda wa pakati, sinthani malo a sprocket kapena gwiritsani ntchito tensioner kuti ikuthandizeni.
Kusamalira Mosinthasintha kwa Mikhalidwe Yapadera Yogwirira Ntchito
Muzochitika zachilendo (monga kukonzanso zida zakale kapena makina otumizira osakhala achizolowezi) komwe unyolo wolumikizirana wokhala ndi manambala osawerengeka sungapeweke, sankhani maulalo osinthira amphamvu kwambiri (monga mbale zachitsulo zosungunuka) ndikuchepetsa katundu woyesedwa ndi 20% kuti muchepetse nthawi yokonza.
Polankhulana ndi ogulitsa, ndikofunikira kufotokoza momveka bwino momwe chipangizocho chikugwirira ntchito (liwiro, katundu, kutentha kwa malo, ndi zina zotero) ndi kuchuluka kwa maulalo a unyolo omwe akufunikira. Ogulitsa apamwamba adzapereka yankho labwino kwambiri kutengera magawo awa, kupewa mavuto ogwirira ntchito omwe amabwera chifukwa cha kuchuluka kwa maulalo a unyolo osayenerera.

IV. N’chifukwa Chiyani Ogula Ayenera Kusamala ndi Tsatanetsatane Umenewu?
Kwa ogula, kuchuluka kwa maulalo a unyolo kumakhudza mwachindunji kudalirika kwa zida ndi mtengo wonse:
Makampani opanga zinthu amatha kutayika ndalama zokwana mayuan zikwizikwi pa ola limodzi chifukwa cha nthawi yogwira ntchito yomwe imabwera chifukwa cha kusweka kwa unyolo.
Zipangizo zakunja monga makina a zaulimi omwe amagwiritsa ntchito maulalo osinthira zinthu zimakhala zosavuta kulephera m'malo opanda fumbi komanso chinyezi, zomwe zimawonjezera ndalama zokonzera.
Ogula zida zotumizira kunja ayenera kutsatira miyezo yapadziko lonse lapansi (monga ISO 606 ndi ANSI B29.1). Miyezo yambiri yapadziko lonse lapansi imalimbikitsa momveka bwino kuti maunyolo okhala ndi maulalo ofanana akhale patsogolo, zomwe zimachepetsa zoopsa zotsatizana ndi malamulo mu malonda.
