Kev cai ua kis tau tus mob rov qab tsis ua haujlwm iav pib iav spur iav teeb

Muaj ntau cov grooves nqaim ntawm tus hniav nto los tsim cov ntug txiav, thiab cov iav zoo li iav machining cov cuab yeej siv los tshuab lub workpiece raws li lub hauv paus ntsiab lus ntawm helical iav meshing. Thaum lub sij hawm ua, cov cuab yeej txiav hwj txwv zoo li chips los ntawm cov hniav nto ntawm lub iav, yog li nws yog hu ua iav shaving cutter. Iav shaving cutters yog siv los ua kom tiav iav hniav tom qab iav hobbing thiab iav shaping (saib iav ua). Feem ntau siv disc-shaped iav shaving cutter yog zoo li lub hardened helical cylindrical iav (Daim duab 1). Qhov zawj ntawm tus hniav nto muaj ob daim ntawv: ib qho yog qhov ncig los yog kauv hlais qhib rau tag nrho lub nplhaib iav. Qhov hla ntawm qhov zawj tuaj yeem yog duab plaub lossis trapezoidal. Qhov no shaving cutter tsuas sharpens lub ntsej muag pem hauv ntej (groove) tom qab blunt. Nws yog tsim rau shaving cutters nrog modulus tsawg dua 1.75 hli; Lwm qhov yog tias cov grooves ntawm ob sab yog impassable, uas tau muab cais nrog comb-shaped inserts. Txhawm rau ua kom cov inserts tuaj yeem thim cov riam, nws muab tso rau ntawm lub hauv paus ntawm txhua tus hniav. Laum slanted qhov. Tom qab zoo li no shaving cutter yog blunt, nws yuav tsum tau regrind tus hniav profile thiab lub cylindrical nto ntawm tus hniav saum. Shaving riam
Txhawm rau txo qhov kev txiav ntawm txhua tus hniav, tus naj npawb ntawm cov hniav ntawm cov iav shaving cutter yog qhov loj, thiab tus naj npawb tseem ceeb feem ntau yog siv kom tsis txhob muaj qhov cuam tshuam nrog cov hniav ntawm cov iav yuav raug txiav, txwv tsis pub qhov yuam kev. ntawm lub iav shaving cutter yuav muab theej rau lub iav kom ua tiav. Raws li cov qauv thoob ntiaj teb, qhov tseeb ntawm cov iav shaving cutters muaj peb hom: AA, A thiab B. Hauv kev tsim khoom tiag tiag, cov iav hniav profile shaving nrog qhov tseeb involute hniav profile shaving cutter feem ntau deviates los ntawm qhov tseeb involute kab ze ntawm lub voj voog ntawm lub iav, thiab yog recessed sab hauv, nrog ib tug sib txawv ntawm 0.01 mus rau 0.03 hli. Cov hniav sib txawv ntawm cov spur iav yog loj dua li ntawm cov iav helical. Yuav kom tau txais qhov tseeb involute hniav profile ntawm workpiece, tus hniav profile ntawm lub shaving cutter yuav tsum tau kho. Hauv kev tsim ntau lawm, cov hniav kho qhov nkhaus ntawm cov shaving cutter yog txiav txim siab los ntawm kev sim.
Lub iav shaving cutter tuaj yeem ua cov txheej txheem ncaj thiab helical sab hauv thiab sab nrauv cylindrical iav, nrog kev ua haujlwm siab thiab du nto. Tsis tas li ntawd, kuj muaj worm iav shaving cutters rau kev ua precision worm gears. Hom thiab qhov tsis sib xws ntawm cov cab iav yooj yim yuav tsum zoo ib yam li cov iav iav ua hauj lwm sib phim rau cov iav iav. Zoo li cov iav shaving cutter, nws muaj ntau qhov nqaim ntawm cov kauv nto los tsim cov ntug txiav thiab muaj cov chips. Worm iav shaving cutters yog ib qho nyuaj rau kev tsim thiab tsuas yog siv thaum machining cab iav uas yuav tsum tau siab precision.
