Kodi chain drive ndi chiyani?Chain drive ndi njira yopatsirana yomwe imatumiza kusuntha ndi mphamvu ya sprocket yoyendetsa galimoto yokhala ndi mawonekedwe apadera a dzino kupita ku sprocket yoyendetsedwa ndi dzino lapadera kudzera mu unyolo.
Kuyendetsa kwa unyolo kumakhala ndi mphamvu yolemetsa (kuvuta kovomerezeka kwakukulu) ndipo ndi koyenera kufalikira pakati pa ma shaft ofanana pamtunda wautali (mamita angapo).Itha kugwira ntchito m'malo ovuta kwambiri monga kutentha kwambiri kapena kuipitsidwa kwamafuta.Ili ndi kulondola kwapang'onopang'ono kopanga ndi kukhazikitsa komanso mtengo wotsika.Komabe, nthawi yomweyo liwiro ndi kufala chiŵerengero cha unyolo pagalimoto si nthawi zonse, kotero kufala ndi wosakhazikika ndipo ali ndi zotsatira zina ndi phokoso.Amagwiritsidwa ntchito kwambiri m'migodi, ulimi, mafuta, njinga zamoto / njinga ndi mafakitale ena ndi makina, komanso kuchuluka kwa zida, zida zam'nyumba, ndi mafakitale apakompyuta.Mzere wopangira umagwiritsanso ntchito maunyolo othamanga kawiri potengera zida.
Zomwe zimatchedwa kuti double speed chain ndi unyolo wodzigudubuza.Kuthamanga kwa V0 kwa unyolo kumakhalabe kosasintha.Nthawi zambiri, liwiro la wodzigudubuza = (2-3) V0.
Zipangizo zamtundu wamba sizimagwiritsa ntchito maunyolo oyendetsa, chifukwa mphamvu zonyamula katundu pansi pazikhalidwe zogwirira ntchito sizokwera, ndipo kutsindika kwambiri kumayikidwa pa liwiro lapamwamba, kulondola kwambiri, kukonza kochepa, phokoso lochepa, ndi zina zotero. Izi ndi zofooka za ma drive a unyolo.Nthawi zambiri, shaft yamagetsi yamakina oyambilira imayendetsa zida zamakina angapo kudzera pamakina.Makina a zida za "axis, multiple movements" akuwoneka kuti ali ndi luso, koma sizodziwika tsopano (kusinthasintha kosasinthika, kusintha kosavutikira, mapangidwe apamwamba), chifukwa ntchito zambiri zomwe zimagwiritsidwa ntchito mu bizinesi zimakhala makamaka zida za pneumatic, ndipo njira zosiyanasiyana Onse ali ndi mphamvu yodziyimira pawokha (silinda), ndipo mayendedwe amatha kuwongoleredwa mosavuta kudzera pamapulogalamu.
Kodi chain drive imapangidwa bwanji?
Chain drive ndi njira yopatsirana yomwe unyolo umatulutsa mphamvu kudzera mu meshing ya ma rollers ndi mano a sprocket.Magawo omwe amakhudzidwa ndi ma chain drive amaphatikiza ma sprockets, maunyolo, osagwira ntchito ndi zina zowonjezera (monga zosinthira kupsinjika, maupangiri a unyolo), omwe amatha kufananizidwa ndikugwiritsidwa ntchito molingana ndi momwe zilili.Pakati pawo, unyolo umapangidwa ndi odzigudubuza, mbale mkati ndi kunja, bushings, zikhomo ndi mbali zina.
Zofunikira za chain drive sizinganyalanyazidwe.
1. Phokoso.Mtunda pakati pa malo awiri odzigudubuza moyandikana pa unyolo wodzigudubuza.Kukula kokulirapo, kukula kwa magawowo, komwe kumatha kutumizira mphamvu zapamwamba ndikunyamula katundu wokulirapo (pakutumiza kwaunyolo wothamanga kwambiri komanso wolemetsa, phula liyenera kusankhidwa kukula kwakukulu).Nthawi zambiri, muyenera kusankha unyolo wokhala ndi phula lochepera lomwe lili ndi mphamvu yotumizira (ngati unyolo wa mzere umodzi ulibe mphamvu zokwanira, mutha kusankha unyolo wamizere yambiri) kuti mupeze phokoso lochepa komanso kukhazikika.
2. Nthawi yomweyo kufala chiŵerengero.Chiŵerengero chotumizira pompopompo cha chain drive ndi i=w1/w2, pomwe w1 ndi w2 ndi liwiro lozungulira la sprocket yoyendetsa ndi sprocket motsatana.Ndiyenera kukwaniritsa zikhalidwe zina (chiwerengero cha mano a sprockets awiriwo ndi ofanana, ndipo kutalika kwa mbali yolimba ndikokwanira kuchuluka kwa nthawi zokulira), ndikokhazikika.
3. Chiwerengero cha mano a pinion.Kuchulukitsa moyenera kuchuluka kwa mano a pinion kumatha kuchepetsa kusayenda bwino komanso kunyamula katundu.
