Kev sib tsoo ntawm Gleason hniav thiab Skiving ntawm Kinberg hniav

Thaum tus naj npawb ntawm cov hniav, modulus, lub kaum sab xis, lub kaum sab xis helix thiab lub taub hau txiav radius 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 xam lub zog yog tib yam: Gleason thiab Kinberg tau tsim lawv tus kheej cov txheej txheem xam lub zog rau cov iav bevel, thiab tau sau cov software tsim iav tsim qauv sib xws. Tab sis lawv txhua tus siv cov qauv Hertz los xam qhov kev ntxhov siab ntawm qhov chaw hniav; siv txoj kev tangent 30-degree los nrhiav qhov seem txaus ntshai, ua rau lub nra hnyav ua rau ntawm qhov kawg ntawm cov hniav los xam qhov kev ntxhov siab ntawm cov hauv paus hniav, thiab siv cov iav cylindrical sib npaug ntawm qhov chaw nruab nrab ntawm cov hniav los kwv yees Xam qhov kev ntxhov siab ntawm qhov chaw hniav, qhov muaj zog ntawm cov hniav thiab qhov tsis kam ntawm qhov chaw hniav rau kev nplaum ntawm cov iav bevel.

2). Lub tshuab hniav Gleason ib txwm suav cov iav dawb paug raws li qhov kawg ntawm lub ntsej muag modulus ntawm qhov kawg loj, xws li qhov siab ntawm lub taub hau, qhov siab ntawm cov hauv paus hniav, thiab qhov siab ntawm cov hniav ua haujlwm, thaum Kinberg suav cov iav dawb paug raws li qhov modulus ib txwm ntawm qhov nruab nrab. parameter. Tus qauv tsim iav Agma tshiab tshaj plaws koom ua ke txoj kev tsim ntawm cov iav bevel bevel, thiab cov iav dawb paug tau tsim raws li qhov modulus ib txwm ntawm qhov nruab nrab ntawm cov hniav iav. Yog li ntawd, rau cov iav helical bevel nrog cov yam ntxwv yooj yim zoo ib yam (xws li: tus lej ntawm cov hniav, qhov nruab nrab modulus ib txwm, qhov nruab nrab helix lub kaum sab xis, lub kaum sab xis siab ib txwm), tsis hais hom kev tsim hniav twg siv, qhov nruab nrab seem ib txwm Qhov ntev yog qhov zoo ib yam; thiab cov kev txwv ntawm cov iav sib npaug cylindrical ntawm qhov nruab nrab yog sib xws (cov kev txwv ntawm cov iav sib npaug cylindrical tsuas yog cuam tshuam nrog tus lej ntawm cov hniav, lub kaum sab xis, lub kaum sab xis siab ib txwm, lub kaum sab xis helix nruab nrab, thiab qhov nruab nrab ntawm qhov chaw hniav ntawm lub iav. Lub cheeb tsam ntawm lub voj voog suab yog cuam tshuam), yog li cov kev txwv ntawm cov duab hniav siv hauv kev kuaj xyuas lub zog ntawm ob lub tshuab hniav yog qhov zoo ib yam.

3). Thaum cov yam ntxwv yooj yim ntawm cov iav zoo ib yam, vim yog qhov txwv ntawm qhov dav ntawm cov hniav hauv qab qhov zawj, lub ces kaum ntawm lub taub hau cuab yeej me dua li ntawm Gleason iav tsim. Yog li ntawd, lub vojvoog ntawm lub arc ntau dhau ntawm cov hauv paus hniav yog qhov me me. Raws li kev tshuaj xyuas iav thiab kev paub dhau los, kev siv lub vojvoog loj dua ntawm lub qhov ntswg arc tuaj yeem ua rau lub vojvoog ntawm lub arc ntau dhau ntawm cov hauv paus hniav thiab txhim kho qhov kev tiv thaiv khoov ntawm cov iav.

Vim tias qhov kev ua haujlwm precision ntawm Kinberg cycloidal bevel gears tsuas yog tuaj yeem khawb nrog cov hniav tawv, thaum Gleason circular arc bevel gears tuaj yeem ua tiav los ntawm thermal post-grinding, uas tuaj yeem paub txog cov hauv paus hniav thiab cov hauv paus hniav hloov pauv. Thiab qhov du thiab tsis du ntawm cov hniav txo qhov ua tau ntawm kev ntxhov siab ntawm cov iav, txo qhov roughness ntawm cov hniav (tuaj yeem ncav cuag Ra ≦ 0.6um) thiab txhim kho qhov tseeb ntawm cov iav (tuaj yeem ncav cuag GB3∽5 qib raug). Ua li no, lub peev xwm ntawm cov iav thiab lub peev xwm ntawm cov hniav kom tiv taus gluing tuaj yeem txhim kho.

4). Lub iav hniav quasi-involute uas Klingenberg tau txais thaum ntxov muaj qhov tsis tshua muaj kev cuam tshuam rau qhov yuam kev ntawm cov iav khub thiab qhov deformation ntawm lub thawv iav vim tias cov kab hniav hauv qhov kev taw qhia ntawm qhov ntev ntawm cov hniav yog involute. Vim yog cov laj thawj tsim khoom, cov hniav no tsuas yog siv rau hauv qee qhov chaw tshwj xeeb. Txawm hais tias Klingenberg cov kab hniav tam sim no yog epicycloid ntev, thiab cov kab hniav ntawm Gleason cov hniav system yog ib qho arc, yuav ib txwm muaj ib qho taw tes ntawm ob kab hniav uas ua tiav cov xwm txheej ntawm cov kab hniav involute. Cov iav tsim thiab ua tiav raws li Kinberg hniav system, "taw tes" ntawm kab hniav uas ua tiav qhov xwm txheej involute yog ze rau qhov kawg loj ntawm cov hniav iav, yog li qhov rhiab heev ntawm cov iav rau qhov yuam kev teeb tsa thiab kev thauj khoom deformation yog qis heev, raws li Gerry Raws li cov ntaub ntawv kev tshaj lij ntawm Sen lub tuam txhab, rau lub iav bevel nrog arc hniav kab, lub iav tuaj yeem ua tiav los ntawm kev xaiv lub taub hau txiav nrog lub cheeb me dua, yog li "taw tes" ntawm kab hniav uas ua tiav qhov xwm txheej involute nyob ntawm qhov nruab nrab thiab qhov kawg loj ntawm qhov chaw hniav. Nyob rau hauv nruab nrab, nws tau ua kom ntseeg tau tias cov iav muaj tib qho kev tiv thaiv rau qhov yuam kev teeb tsa thiab lub thawv deformation raws li Kling Berger iav. Txij li thaum lub vojvoog ntawm lub taub hau txiav rau kev ua haujlwm Gleason arc bevel iav nrog qhov siab sib npaug yog me dua li qhov rau kev ua haujlwm bevel iav nrog tib cov kev cai, "taw tes" uas ua tiav qhov xwm txheej involute tuaj yeem lav tias yuav nyob nruab nrab thiab qhov kawg loj ntawm qhov chaw hniav. Thaum lub sijhawm no, lub zog thiab kev ua tau zoo ntawm lub iav tau txhim kho.

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

①. Cov iav Klingenberg raug khawb tom qab kev kho cua sov, tab sis cov hniav shrinkage uas ua los ntawm Gleason iav tsis tiav tom qab kev kho cua sov, thiab qhov tseeb tsis zoo li qhov qub.

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

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

Tam sim no, kev tsim cov iav feem ntau siv Kleinberg txoj kev, tsuas yog tias cov kab hniav hloov pauv los ntawm epicycloid ntev mus rau arc, thiab cov hniav raug av tom qab kev kho cua sov.
