Pamagalimoto ambiri apanyumba (komanso pamagalimoto ambiri opangidwa kunja), njira yachikhalidwe yoyendetsera liwiro kuchokera ku gearbox ndi shaft yapadera yosinthika imagwiritsidwa ntchito.Werengani za momwe shaft yosinthira liwiro ili, momwe imagwirira ntchito komanso momwe imagwirira ntchito m'nkhaniyi.
Kodi flex speedometer shaft ndi chiyani?
Shaft yosinthika ya Speedometer ndi gawo loyendetsa ma mechanical and electromechanical automotive speedometers.Ntchito ya shaft yosinthika ndikusamutsa torque kuchokera ku shaft yachiwiri ya gearbox kupita ku liwiro la liwiro ndi odometer yothamanga.Komanso, gawoli limathetsa mavuto angapo aukadaulo komanso kapangidwe kake, mwachitsanzo, imawonetsetsa kuti liwiro la liwiro likuyenda bwino mosasamala kanthu za malo ake okhudzana ndi bokosi la gear, limakupatsani mwayi wosiya magiya olimba, ndi zina zambiri.
M'zaka makumi awiri zapitazi, ma shafts osinthika a speedometer ataya kwambiri malo opangira masitima apamtunda ndi ma speedometer amagetsi, koma kutumizirana ma flexible kumagwiritsidwabe ntchito kwambiri pamagalimoto otsika mtengo komanso mafakitale apanyumba.Makina othamanga kapena othamanga a electromechanical okhala ndi shaft drive yosinthika ndiyo njira yosavuta komanso yotsika mtengo kwambiri yoyezera liwiro, chifukwa chake sizingatheke kusinthidwa kwathunthu ndi zida zamagetsi m'zaka zikubwerazi.
Kodi shaft yosinthika ya speedometer imagwira ntchito bwanji?
Shaft yosinthika ili ndi chipangizo chosavuta kwambiri.Maziko a shaft ndi chingwe chachitsulo, chopotoka kuchokera ku zigawo zitatu, zinayi kapena zisanu za waya wozungulira (chingwecho chimakhalanso ndi chitsulo chachitsulo, chomwe waya amavulala).Malekezero onse a chingwe ali ndi gawo lalikulu la mtanda ndi mbali ya 2, 2.6 kapena 2.7 mm kutalika kwa 20-25 mm - pogwiritsa ntchito lalikulu, chingwecho chimagwirizanitsidwa ndi galimoto ndi speedometer.
Chingwecho chimayikidwa muchitetezo cha zida (kapena zida zankhondo) - chubu chosinthika chopotoka kuchokera ku chitsulo chovulala kapena tepi yapulasitiki.Chitetezo cha zida za 2/3 zautali chimadzazidwa ndi mafuta amtundu wa Litol - izi zimatsimikizira kusinthasintha kwake kwa chingwe popanda kupanikizana, komanso chitetezo cha dzimbiri.Zidazo zimakhalanso ndi zokutira zoteteza zopangidwa ndi PVC, polyethylene kapena mphira wosagwira mafuta.Akasupe odzitchinjiriza amatha kukhala patsinde, komanso ma cuffs amodzi kapena angapo (bushings) kuti ateteze kuwonongeka kwa chipolopolo cha shaft podutsa mabowo muzinthu zamagalimoto.
Pamapeto a chitetezo cha zida, nsonga zamabele zimamangiriridwa mwamphamvu - zigawo za conical zomwe mtedza wa mgwirizano umapezeka kuti ugwirizane ndi gearbox ndi speedometer.Mtedza ndi nsonga zamabele zitha kupangidwa ndi pulasitiki kapena chitsulo.Kumbali ya gearbox, mtedza uli ndi kukula kwakukulu.Mbali yomweyo ya chingwe pali kutseka (kukulitsa) wochapira, amene amakhala pa phewa mkati nsonga ya nsonga zamabele, ndipo amalepheretsa kusamutsidwa kotalika kwa chingwe mkati mwa zida (pamafunikanso kutumikira kutsinde - pambuyo kuchotsa washer , mutha kutulutsa chingwe ndikudzaza zidazo ndi mafuta).
Makhalidwe ndi mapangidwe a ma shafts osinthika opangidwa ku Russia amayendetsedwa ndi GOST 12391-77 standard.Mogwirizana ndi muyezo, magalimoto ndi njinga zamoto zili ndi ma shaft osinthika a ma Speedometer okhala ndi kuzungulira kumanzere kwa mtundu wopindika (ndi chingwe chochotseka, monga tafotokozera pamwambapa) ndi mitundu ingapo yolumikizira kuchokera ku gearbox ndi Speedometer (komanso. monga ma shaft okha, zolumikizira zolumikizira kuziyika ndizokhazikika).Kutalika kwa ma shafts kumatha kuchoka pa 530 mm mpaka mamita angapo, koma ma shaft omwe amagwiritsidwa ntchito kwambiri amachokera ku 1 mpaka 3.5 mamita.
Kodi shaft yosinthika yosinthika imagwira ntchito bwanji?
Shaft imagwira ntchito mosavuta.Galimotoyo ikamayenda, torque yochokera ku shaft yachiwiri ya gearbox imafalikira kudzera mu giya ndi chida chomangira mpaka kumapeto kwa chingwe cha shaft.Chingwecho, chifukwa cha kapangidwe kake, chimakhala ndi kukhazikika kwamphamvu (koma kokha ndi kuzungulira kumanzere, ndikuzungulira kozungulira kumayamba kumasuka ndipo kumatha kukhazikika mkati mwa zida zankhondo), kotero kuti mbali imodzi ikapindika, imazungulira kutalika kwake konse.Komanso, chingwe chimazungulira lonse, kotero kusintha kwa liwiro la shaft yachiwiri ya gearbox pafupifupi nthawi yomweyo kumakhudza kusintha kwa kayendetsedwe ka galimoto yothamanga mu speedometer.Chifukwa chake, torque yochokera ku giya ya gearbox imaperekedwa nthawi zonse ndi chingwe chosinthika cha shaft kupita ku msonkhano wothamanga, ndipo dalaivala amatha kutsata liwiro lagalimoto.
M'kupita kwa nthawi, chingwecho chimataya mphamvu zake, malekezero ake a gawo lalikulu ndikusweka (kutaya geometry), ndipo amafuna kusinthidwa.Komabe, m'malo ndi kukonza sikofunikira nthawi zambiri - gwero la ma shafts osinthika mpaka 2 mita kutalika ndi pafupifupi 150,000 km, mitsinje yayitali - pafupifupi 75,000 km.
Pakavala kapena kusweka, shaft yosinthika ya Speedometer iyenera kusinthidwa, ndipo izi ziyenera kuchitika posachedwa - kuyendetsa galimoto yokhala ndi liwiro losagwira ntchito ndikoletsedwa ndi malamulo apamsewu (ndime 7.4 ya " Mndandanda wa zolakwika ndi zikhalidwe zomwe kuyendetsa galimoto ndikoletsedwa").Ndipo ngakhale, molingana ndi lamulo, cholakwika cha speedometer sichingabweretse chilango, komabe, kuwonongeka kumeneku kumapangitsa kukhala kosatheka kupeza khadi la matenda, ndipo kungayambitse kuphwanya malire a liwiro - ndipo kuphwanya koteroko kumalangidwa kale ndi chindapusa ndipo kungakhale ndi zambiri. zotsatira zoyipa.
