Sib tsoo ntawm Gleason hniav thiab Skiving ntawm Kinberg hniav

Thaum tus naj npawb ntawm cov hniav, modulus, lub kaum sab xis siab, lub kaum sab xis helix thiab cutter lub taub hau vojvoog yog tib yam, lub zog ntawm cov hniav arc contour ntawm Gleason cov hniav thiab cov hniav cycloidal contour ntawm Kinberg yog tib yam. Cov laj thawj yog raws li nram no:

1). Cov txheej txheem rau kev suav lub zog yog tib yam: Gleason thiab Kinberg tau tsim lawv tus kheej lub zog suav txoj hauv kev rau cov iav bevel iav, thiab tau muab tso ua ke cov iav tsim tsom iav software. Tab sis lawv txhua tus siv Hertz formula los xam qhov kev sib cuag ntawm tus hniav nto; siv 30-degree tangent txoj kev los nrhiav qhov txaus ntshai seem, ua kom lub load ua ntawm cov hniav ntaj los xam cov hniav hauv paus dabtsi yog khoov kev nyuaj siab, thiab siv qhov sib npaug cylindrical iav ntawm cov hniav nto midpoint seem kom kwv yees kwv yees tus hniav nto tiv lub zog, hniav siab dabtsi yog khoov zog thiab hniav nto kuj mus gluing ntawm kauv bevel iav.

2). Gleason cov hniav ib txwm suav cov iav tsis muaj qhov ntsuas raws li qhov kawg ntawm lub ntsej muag modulus ntawm qhov kawg ntawm qhov loj, xws li lub taub qhov siab, cov hniav hauv paus qhov siab, thiab qhov siab ntawm cov hniav, thaum Kinberg xam cov iav dawb paug raws li qhov qub modulus ntawm qhov nruab nrab. parameter. Qhov tseeb Agma iav tsim qauv sib koom ua ke cov qauv tsim ntawm cov kauv bevel iav dawb paug, thiab cov iav tsis muaj iav yog tsim raws li qhov qub modulus ntawm qhov nruab nrab ntawm cov iav hniav. Yog li ntawd, rau lub helical bevel gears nrog tib lub hauv paus tsis tau (xws li: tus naj npawb ntawm cov hniav, midpoint ib txwm modulus, midpoint helix lub kaum sab xis, lub kaum sab xis ntawm lub siab), txawm li cas los xij ntawm cov hniav tsim siv, qhov nruab nrab ntawm qhov ntev yog yeej zoo ib yam; thiab cov tsis sib npaug cylindrical iav ntawm qhov nruab nrab ntawm qhov nruab nrab yog qhov sib xws (qhov tsis sib xws ntawm qhov sib npaug cylindrical iav tsuas yog muaj feem xyuam rau cov hniav, lub kaum sab xis, lub kaum sab xis, lub kaum sab xis nruab nrab, thiab nruab nrab ntawm cov hniav ntawm qhov chaw. iav txoj kab uas hla ntawm lub voj voog yog muaj feem xyuam), yog li cov hniav zoo li tsis siv nyob rau hauv lub zog xyuas ntawm ob lub tshuab hniav yog qhov zoo ib yam.

3). Thaum cov txheej txheem tsis zoo ntawm cov iav yog tib yam, vim qhov kev txwv ntawm qhov dav ntawm cov hniav hauv qab zawj, lub kaum sab xis ntawm lub cuab yeej taw qhia me dua li ntawm Gleason iav tsim. Yog li ntawd, lub vojvoog ntawm ntau dhau arc ntawm cov hauv paus hniav yog qhov me me. Raws li cov iav tsom iav thiab cov kev paub dhau los, siv lub vojvoog loj ntawm cov cuab yeej lub qhov ntswg arc tuaj yeem ua rau lub vojvoog ntau dhau ntawm cov hniav hauv paus hniav thiab txhim kho qhov khoov ntawm cov iav.

Vim hais tias cov precision machining ntawm Kinberg cycloidal bevel iav tsuas tuaj yeem raug khawb nrog cov hniav tawv, thaum Gleason ncig arc bevel iav tuaj yeem ua tiav los ntawm thermal post-sib tsoo, uas tuaj yeem paub cov hauv paus lub khob hliav qab thiab cov hniav hauv paus hniav. Thiab qhov smoothness ntau dhau ntawm cov hniav tuaj yeem txo qhov muaj peev xwm ntawm kev ntxhov siab ntawm cov iav, txo qhov roughness ntawm cov hniav (tuaj yeem ncav cuag Ra≦0.6um) thiab txhim kho qhov ntsuas qhov tseeb ntawm cov iav (tuaj yeem ncav cuag GB3∽5 qib raug) . Nyob rau hauv txoj kev no, lub peev xwm ntawm cov iav thiab lub peev xwm ntawm tus hniav nto los tiv thaiv gluing tuaj yeem txhim kho.

4). Lub quasi-involute hniav kauv bevel iav saws los ntawm Klingenberg nyob rau hauv thaum ntxov hnub muaj tsawg rhiab heev rau lub installation yuam kev ntawm lub iav khub thiab lub deformation ntawm lub gearbox vim hais tias cov hniav kab nyob rau hauv cov kev taw qhia ntawm cov hniav ntev yog involute. Vim yog kev tsim khoom, cov hniav no tsuas yog siv hauv qee qhov tshwj xeeb. Txawm hais tias Klingenberg cov kab hniav tam sim no yog ib qho kev ncua ntev, thiab cov kab hniav ntawm Gleason cov hniav yog ib qho arc, yuav muaj ib qho taw tes ntawm ob kab hniav uas ua rau cov kab mob ntawm cov hniav involute. Gears tsim thiab ua tiav raws li Kinberg tus hniav system, "point" ntawm cov kab hniav uas ua rau cov kab mob tsis zoo nyob ze rau qhov kawg ntawm cov hniav iav, yog li qhov rhiab heev ntawm cov iav mus rau qhov yuam kev installation thiab load deformation yog heev. qis, raws li Gerry Raws li cov ntaub ntawv kev lag luam ntawm Sen tuam txhab, rau cov kauv bevel iav nrog arc hniav kab, cov iav tuaj yeem ua tiav los ntawm kev xaiv lub taub hau cutter nrog me me. txoj kab uas hla, yog li ntawd cov "point" ntawm cov kab hniav uas ua tau raws li qhov kev mob tshwm sim nyob rau ntawm qhov nruab nrab thiab qhov loj kawg ntawm cov hniav. Nyob rau hauv nruab nrab, nws tau ua kom ntseeg tau tias cov iav muaj qhov tsis sib xws rau kev teeb tsa tsis raug thiab lub thawv deformation raws li Kling Berger zog. Txij li thaum lub vojvoog ntawm lub taub hau cutter rau machining Gleason arc bevel iav nrog qhov siab sib npaug yog me dua qhov uas rau machining bevel gears nrog tib qhov tsis muaj, "point" uas txaus siab rau cov xwm txheej involute tuaj yeem lav tau nyob nruab nrab ntawm qhov nruab nrab thiab qhov loj. kawg ntawm tus hniav nto. Thaum lub sijhawm no, lub zog thiab kev ua haujlwm ntawm lub iav tau txhim kho.

5). Yav dhau los, qee cov neeg xav tias Gleason cov hniav ntawm cov iav loj loj yog qhov qis dua rau Kinberg cov hniav, feem ntau yog vim li cas hauv qab no:

①. Lub Klingenberg lub zog yog khawb tom qab kev kho cua sov, tab sis cov hniav shrinkage ua tiav los ntawm Gleason lub zog tsis tiav tom qab kev kho cua sov, thiab qhov tseeb tsis zoo li qub.

②. Lub vojvoog ntawm lub taub hau cutter rau kev ua cov hniav shrinkage yog loj dua li ntawm cov hniav ntawm Kinberg, thiab lub zog ntawm cov iav yog qhov phem dua; Txawm li cas los xij, lub vojvoog ntawm lub taub hau cutter nrog cov hniav arc ncig yog me dua li rau kev ua cov hniav shrinkage, uas zoo ib yam li cov hniav ntawm Kinberg. Lub vojvoog ntawm lub taub hau cutter ua yog sib npaug.

③. Gleason siv los pom zoo rau cov iav me me thiab ntau cov hniav thaum lub iav txoj kab uas hla yog tib yam, thaum Klingenberg loj-modulus iav siv lub modulus loj thiab cov hniav me me, thiab lub zog khoov ntawm lub iav feem ntau yog nyob ntawm. ntawm lub modulus, yog li cov gram Lub zog khoov ntawm Limberg yog ntau dua li ntawm Gleason.

Tam sim no, tus qauv tsim ntawm lub zog pib siv Kleinberg txoj kev, tshwj tsis yog tias cov kab hniav raug hloov los ntawm qhov txuas ntxiv mus rau ib qho arc, thiab cov hniav yog av tom qab kev kho cua sov.
