Helical iav: Ib qho kev daws teeb meem rau siab - kis tau tus mob ceev
Helical iav:Kev daws teeb meem ntsiag to rau siab -Speed Transmissions. Nyob rau hauv lub xyoo pua puv 19, thaum lub cav locomotives siab tshaj 80 km / h, lub suab nrov thiab kev vibration teeb meem ntawm spur gears ua unbearable. Qhov no yog qhov uas cov iav helical tuaj rau hauv - lawv cov hniav profile yog helical, zoo li cov iav iav hlais rau hauv nyias daim thiab twisted ntawm lub kaum sab xis. Qhov kev tsim no hloov cov hniav ntawm qhov chaw sib cuag los ntawm ib qho taw tes mus rau ib kab, ua rau cov txheej txheem meshing maj mam li ob tug neeg tuav tes, txo qhov cuam tshuam rau ntau tshaj 60%.
Cov txiaj ntsig tseem ceeb tau tshwm sim hauv peb yam:thaj chaw tiv tauj yog 300% loj dua li ntawm spur gears, nce load peev los ntawm 2-3 zaug; Lub axial quab yuam tsim los ntawm lub kaum sab xis helix tuaj yeem raug cuam tshuam los ntawm cov kabmob thrust, ua rau nws haum rau cov xwm txheej ceev tshaj 10,000 rpm; ib lub tshuab hluav taws xob cov khoom siv hluav taws xob qhov kev ntsuam xyuas tau pom tias lub suab nrov ntawm lub helical gearbox yog 15 dB qis dua li ntawm lub spur gearbox, sib npaug rau lub suab hloov pauv ntawm lub nroog tsis khoom mus rau lub tsev qiv ntawv.
Txawm li cas los xij, qhov txiaj ntsig no los ntawm tus nqi:helical iav machining yuav tsum tau tshwj xeeb iav hobbing tshuab, raug nqi 40% ntau tshaj spur iav; lub axial quab yuam tsub kom cov kabmob load, yuav tsum tau kim dua tapered menyuam bearings. Cov kws ua haujlwm ntawm Siemens hauv tebchaws Yelemes tau tshawb pom tias tsis quav ntsej axial quab yuam sib npaug hauv helical iav teeb tuaj yeem ua rau lub neej luv luv los ntawm 70%.
Cov ntawv thov raug pom thoob plaws hauv siab -kev tsim khoom kawg:siab -kev ceev rail traction motors, aircraft engine accessory drives, thiab precision sib tsoo tshuab spindles. Nyob rau hauv lub zog tshiab lub tsheb reducers, helical iav yog tus qauv-Tesla Model 3's thib ob-theem reducer siv helical iav nrog 20℃helix lub kaum sab xis, ua tiav kev sib kis ntawm 97%.
