Gear Sib Tsoo: IT6-IT4 → IT3, Ra: 0.8-0.2 µm
Txoj Cai: Daim ntawv sib tsoo thiab tsim kev sib tsoo.
Daim ntawv sib tsoo (IT6-IT5, Ra: 0.8-0.4 µm)
Daim ntawv sib tsoo siv lub log sib tsoo rau lub tshuab ua haujlwm. Nws muab cov khoom tsim tau ntau dua rau kev tsim cov iav tab sis qis machining raug thiab tsis tshua siv.
Tsim kev sib tsoo
Conical Log Sib Tsoo:Lub log sib tsoo muaj tus ntoo khaub lig-sectional hniav profile zoo ib yam li cov khib nyiab. Lub workpiece yob mus rau sab xis, siv sab xis ntawm kev sib tsoo lub log rau sab xis ntawm ib qho hniav, los ntawm lub hauv paus mus rau qhov kawg. Tom qab ntawd, lub workpiece dov mus rau sab laug, thiab sab laug ntawm kev sib tsoo log grinds sab laug ntawm tib cov hniav, kuj los ntawm cov hauv paus hniav mus rau qhov kawg. Thaum ob sab ntawm thawj cov hniav yog hauv av tag nrho, lub sib tsoo lub log yuav thim rov qab, lub workpiece indexes, thiab ces dov mus rau sab xis dua los zom cov hniav thib ob. Cov txheej txheem no rov ua dua kom txog thaum tag nrho cov hniav nyob hauv av.
Gear Lapping: IT7-IT6, Ra: 1.6-0.2 µm
Khoom siv: Gearlapping tshuab.
Lapping tus neeg sawv cev: Abrasive nplej: 220 #-240 #, nrog cov roj lubricating.
Yam ntxwv: Zoo ib yam li honing, lapping tsuas tuaj yeem txo qhov roughness thiab tsis tuaj yeem txhim kho cov hniav profile raug.
Parallel Axis Lapping Method:
Txheej txheem:Lub lapping log lub axis yog parallel rau ntawm lub iav yog lapped. Thaum lub sij hawm lapping, lub iav tsav lub lapping log nyob rau hauv ib tug dawb meshing suab tsis muaj backlash. Lub iav kuj ua ib qho axial reciprocating motion, thaum lub log lapping yog me ntsis braked. Tom qab ib lub sij hawm, lub lapping log thiab lub iav tig nyob rau hauv lub opposite kev taw qhia kom sib npaug lap ob sab ntawm cov hniav.
Yam ntxwv:Vim qhov tsis sib xws ntawm zawv zawg qhov chaw ntawm cov hniav, tus nqi lapping kuj tsis sib xws. Qhov zawv zawg ceev thiab lapping ntau dua ntawm lub ntsis thiab cov hauv paus hniav ntawm cov hniav.
Iav Tsav nrog Tsiv Axes
Planetary iav tsav los ntawm ntau hom, thiab lawv cov kev ua tau zoo tuaj yeem sib txawv. Xaiv hom tsim nyog raws li kev ua haujlwm yog qhov tseem ceeb. Cov hom muaj xws li:
Ordinary planetary kis tau tus mob muaj xws li lub hnub iav, ntiaj chaw iav, iav sab hauv, thiab lub ntiaj teb cov cab kuj.
Epicyclic iav kis tau tus mob me me sib txawv.
Cycloidal pinion kis tau tus mob.
Harmonic tsav kis tau tus mob.
Planetary gear drives feem ntau yog tsim los ntawm kev sib luag -axis gears, yam ntxwv ntawm lawv qhov loj me thiab lub teeb yuag. Cov input thiab output shafts tuaj yeem yog coaxial. Lawv daim ntawv thov tau nce zuj zus.
