Cov neeg feem coob xaiv txoj siv sij hawm randomly, thiab lawv yuav tsis paub cov hniav zoo li lub sij hawm siv. Synchronous siv feem ntau muab faib rau hauv cov hniav trapezoidal thiab ncig arc cov hniav
(1) Trapezoidal hniav synchronous siv
Kev ntxhov siab ntawm cov hniav trapezoidal yog concentrated ntawm cov hniav hauv paus hniav. Thaum txoj kab uas hla ntawm lub rubey me me, cov hniav zoo li cov hniav sib tsoo ntawm cov hniav sib tsoo yuav raug deformed (polygon nyhuv, tib yam li cov saw sib kis), uas yuav cuam tshuam rau cov meshing nrog txoj siv cov hniav thiab yooj yim tsim suab nrov thiab kev co, uas yog qhov tsis zoo. rau lub ntsiab kis tau tus mob nrog kev kub ceev. Yog li ntawd, txoj siv tawv trapezoidal synchronous siv tsis tshua muaj siv nyob rau hauv lub ntsiab tsav ntawm NC tshuab cuab yeej, tshwj xeeb tshaj yog machining chaw. Feem ntau, nws tsuas yog siv rau hauv kev tsav tsheb nrog kev ceev qis lossis lub zog tsav nrog lub zog tsav qis.
Muaj feem xyuam: lub sijhawm uas tsis muaj kev ceev thiab tsis tshua muaj hluav taws xob sib kis
Qhov zoo: siab kis tau tus mob thiab tus nqi qis
Qhov tsis zoo: cov hauv paus hniav yog ib qho yooj yim kom muaj kev ntxhov siab, yog li lub peev xwm thauj khoom tsawg; Lub suab nrov thiab kev co.
(2) Circular arc hniav synchronous siv
Lub voj voog arc hniav synchronous siv overcomes cov shortcomings ntawm lub trapezoidal hniav synchronous siv, homogenizes kev nyuaj siab thiab txhim kho cov meshing. Yog li ntawd, nyob rau hauv lub machining chaw, seb nws yog lub ntsiab tsav los yog servo pub tsav, thaum siv txoj siv yog yuav tsum tau, ncig arc hniav synchronous toothed siv yog ib txwm muab qhov tseem ceeb.
Daim ntawv thov: me me suab, me me backlash, ntau haum rau positioning, siab torque
Qhov zoo: kev sib kis tau zoo, kev sib kis loj torque thiab tsis tshua muaj suab nrov, uas tuaj yeem tiv thaiv kev cuam tshuam hauv cov txheej txheem ntawm cov hniav meshing
Disadvantages: tus nqi yog me ntsis siab dua.
