Mtundu wolephera wa gearbox

Kupyolera mu kusanthula kagwiritsidwe ntchito ka gearbox, sikovuta kudziwa cholakwika chake.Dongosolo lonse la gearbox limaphatikizapo zonyamula, magiya, ma shafts otumizira, mawonekedwe amabokosi ndi zinthu zina.Monga makina odziwika bwino amagetsi, amatha kulephera kwa ziwalo zamakina pomwe akuyenda mosalekeza, makamaka magawo atatu a ma bearings, magiya ndi ma shafts opatsirana.Kuthekera kwa zolephera zina ndizotsika kwambiri kuposa iwo.

Magiya akamagwira ntchito, amalephera kugwira ntchito chifukwa cha zovuta zosiyanasiyana.Mtengo wa magawo ogwira ntchito umaposa mtengo wovomerezeka wovomerezeka, womwe umabweretsa kulephera kwa ma gearbox.Palinso mitundu yosiyanasiyana ya mawu.Kuyang'ana zochitika zonse, zimagawidwa makamaka m'magulu awiri: choyamba ndikuti magiya amapangidwa pang'onopang'ono panthawi yozungulira.Pamene kunja kwa bokosi la gear kumanyamula katundu wochuluka, mphamvu yothamanga ndi mphamvu yotsetsereka idzawonekera pochotsa magiya a meshing.Kugundana kwamphamvu pakutsetsereka kumangoyang'ana mbali zonse ziwiri za mtengowo.M'kupita kwa nthawi, kugwira ntchito kwamakina kwanthawi yayitali kumapangitsa kuti magiya azimatidwa Kupezeka kwa ming'alu ndi kuchuluka kwa mavalidwe kumapangitsa kuti kusweka kwa zida kusapeweke.Mtundu wina wa zolakwika ndi chifukwa cha kunyalanyaza kwa ogwira ntchito poika zidazo chifukwa sadziwa bwino ntchito yotetezeka kapena kuphwanya ndondomeko ya opaleshoni ndi zofunikira, kapena ngozi yobisika imakwiriridwa chifukwa cha vutolo poyamba. kupanga.Cholakwa ichi nthawi zambiri chifukwa dzenje lamkati ndi bwalo lakunja la zida si pa likulu lomwelo, cholakwa mawonekedwe ndi olamulira kugawa asymmetry mu zokambirana meshing wa zida.

Kuphatikiza apo, mu chowonjezera chilichonse cha gearbox, shaft ndi gawo lomwe limatha kutayika mosavuta.Katundu wokulirapo ukakhudza tsinde, shaft imapindika mwachangu, ndikupangitsa cholakwika ichi cha gearbox.Mukazindikira cholakwika cha bokosi la gear, zotsatira za shaft zokhala ndi ma deformation osiyanasiyana pa cholakwika cha gearbox ndizosagwirizana.Zachidziwikire, padzakhalanso magwiridwe antchito osiyanasiyana.Chifukwa chake, kupotoza kwa shaft kumatha kugawidwa kukhala kovuta komanso kofatsa.Kusakhazikika kwa shaft kumabweretsa kulephera.Zifukwa zake ndi izi: pogwira ntchito kumalo olemetsa kwambiri, kusinthika kumakhala kosapeŵeka pakapita nthawi;Shaft yokhayo yawonetsa zolakwika zingapo munjira zambiri zaukadaulo, monga kupanga, kupanga ndi kukonza, zomwe zimapangitsa kusalinganika kwakukulu kwa shaft yomwe yangoponya kumene.
