Gleasoncov iav bevel spiralyog ib hom iav bevel tshwj xeeb uas tsim los xa lub zog ntawm cov ncej sib tshuam, feem ntau ntawm lub kaum sab xis 90 degree. Qhov ua rau Gleason system txawv yog nws cov hniav geometry thiab txoj kev tsim khoom tshwj xeeb, uas muab kev txav mus los du, muaj peev xwm siab torque, thiab ua haujlwm ntsiag to. Cov iav no siv dav hauv kev sib kis tsheb, kev lag luam, thiab aerospace qhov twg kev ntseeg tau thiab kev raug yog qhov tseem ceeb.
Lub Gleason system tau tsim los txhim kho qhov ncaj thiabZerol bevel iavlos ntawm kev qhia txog cov hniav uas nkhaus thiab zoo li lub kauv. Cov hniav uas zoo li lub kauv no ua rau maj mam sib koom ua ke ntawm cov hniav, txo cov suab nrov thiab kev co thaum tseem ua rau muaj kev sib hloov ceev dua thiab muaj peev xwm thauj khoom tau zoo dua. Tus qauv tsim kuj ua rau muaj kev sib cuag thiab lub zog ntawm qhov chaw, ua kom muaj kev xa hluav taws xob zoo thaum muaj cov khoom hnyav lossis cov khoom hnyav.
Txhua khub iav Gleason spiral bevel muaj ib lub pinion thiab ib lub iav mating, tsim nrog cov geometry sib phim. Cov txheej txheem tsim khoom yog tshwj xeeb heev. Nws pib nrog forging lossis precision casting ntawm cov hlau alloy blanks, xws li 18CrNiMo7-6, ua raws li kev txiav ntxhib, hobbing, lossis shaping los tsim cov iav pib. Cov txheej txheem siab heev xws li 5-axis machining, skiving, thiab hard cutting ua kom muaj qhov tseeb siab thiab qhov ua tiav ntawm qhov chaw. Tom qab kev kho cua sov xws li carburization (58–60 HRC), cov iav raug lapping lossis sib tsoo kom ua tiav qhov sib xyaw zoo meej ntawm pinion thiab iav.
Cov geometry ntawm Gleason spiral bevel gears yog txhais los ntawm ntau qhov tseem ceeb - lub kaum sab xis ntawm lub kauv, lub kaum sab xis ntawm lub siab, qhov deb ntawm lub suab, thiab qhov dav ntawm lub ntsej muag. Cov kev ntsuas no tau suav meej kom ntseeg tau tias cov qauv sib cuag hniav raug thiab kev faib khoom thauj. Thaum lub sijhawm tshuaj xyuas zaum kawg, cov cuab yeej xws li lub tshuab ntsuas kev sib koom tes (CMM) thiab kev tshuaj xyuas kev sib cuag hniav (TCA) xyuas kom meej tias cov iav teeb tsa ua tau raws li DIN 6 lossis ISO 1328-1 chav kawm raug.
Thaum ua haujlwm, Gleason spiralcov iav bevelmuab kev ua haujlwm zoo thiab ruaj khov txawm tias nyob rau hauv cov xwm txheej nyuaj. Cov hniav nkhaus muab kev sib cuag tas mus li, txo qhov kev ntxhov siab thiab kev hnav. Qhov no ua rau lawv zoo tagnrho rau cov khoom sib txawv hauv tsheb, cov thawv iav tsheb thauj khoom, cov tshuab hnyav, cov tshuab tsav nkoj, thiab cov cuab yeej hluav taws xob. Tsis tas li ntawd, lub peev xwm los kho cov qauv hniav thiab qhov deb ntawm kev teeb tsa tso cai rau cov engineers los ua kom zoo dua qhov tsim rau qhov tshwj xeeb torque, ceev, thiab qhov chaw txwv.
