Ukugaya izinyo leGleason kanye nokusika izinyo leKinberg

Uma inani lamazinyo, i-modulus, i-pressure angle, i-helix angle kanye ne-cutter head radius zifana, amandla amazinyo e-arc contour amazinyo e-Gleason kanye namazinyo e-cycloidal contour aseKinberg ayafana. Izizathu zimi kanje:

1). Izindlela zokubala amandla ziyafana: UGleason noKinberg bathuthukise izindlela zabo zokubala amandla amagiya e-spiral bevel, futhi bahlanganise isofthiwe yokuhlaziya ukwakheka kwegiya ehambisanayo. Kodwa bonke basebenzisa ifomula yeHertz ukubala ukucindezeleka kokuthintana kobuso bezinyo; sebenzisa indlela ye-tangent engama-degree angu-30 ukuthola ingxenye eyingozi, wenze umthwalo usebenze esicongweni sezinyo ukubala ukucindezeleka kokugoba kwezimpande zezinyo, bese usebenzisa igiya eliyindilinga elilinganayo lengxenye ephakathi nendawo yezinyo ukuze ulinganisele ukuthila amandla okuthintana kobuso bezinyo, amandla okugoba aphezulu ezinyo kanye nokumelana kobuso bezinyo ekunamathelisweni kwamagiya e-spiral bevel.

2). Uhlelo lwendabuko lwamazinyo eGleason lubala amapharamitha angenalutho egiya ngokuya ngemodulus yobuso bokuphela kwengxenye enkulu, njengokuphakama kwethiphu, ukuphakama kwempande yezinyo, kanye nokuphakama kwezinyo elisebenzayo, kuyilapho iKinberg ibala i-blank gear ngokuya ngemodulus evamile yepharamitha ye-midpoint. Izinga lakamuva lokuklama igiya le-Agma lihlanganisa indlela yokuklama ye-spiral bevel gear blank, futhi amapharamitha angenalutho egiya aklanywe ngokuya ngemodulus evamile yengxenye ephakathi yamazinyo egiya. Ngakho-ke, kumagiya e-helical bevel anemingcele efanayo eyisisekelo (njenge: inani lamazinyo, i-midpoint normal modulus, i-midpoint helix angle, i-normal pressure angle), kungakhathaliseki ukuthi kusetshenziswa luphi uhlobo lokuklama izinyo, isigaba se-midpoint normal Ubukhulu buyafana; futhi amapharamitha egiya eliyindilinga elilinganayo esigabeni samaphakathi ayavumelana (amapharamitha egiya eliyindilinga elilinganayo ahlobene kuphela nenani lamazinyo, i-angle yephimbo, i-angle evamile yokucindezela, i-angle ye-midpoint helix, kanye ne-midpoint ebusweni bezinyo legiya. Ububanzi besiyingi sephimbo buhlobene), ngakho-ke amapharamitha okuma kwezinyo asetshenziswa ekuhlolweni kwamandla kwezinhlelo ezimbili zamazinyo ngokuyisisekelo afana.

3). Uma amapharamitha ayisisekelo egiya afana, ngenxa yomkhawulo wobubanzi bomsele ongezansi wezinyo, irediyasi yekhoneni yesihloko sethuluzi incane kuneyomklamo wegiya le-Gleason. Ngakho-ke, irediyasi ye-arc eyeqile yempande yezinyo incane kakhulu. Ngokusho kokuhlaziywa kwegiya kanye nokuhlangenwe nakho okusebenzayo, ukusebenzisa irediyasi enkulu ye-arc yekhala lethuluzi kungandisa irediyasi ye-arc eyeqile yempande yezinyo futhi kuthuthukise ukumelana kokugoba kwegiya.

Ngoba ukucutshungulwa ngokunemba kwamagiya e-Kinberg cycloidal bevel kungakhuhlwa kuphela ngezinsika zamazinyo eziqinile, kuyilapho amagiya e-Gleason circular arc bevel angacutshungulwa ngokushisa ngemuva kokugaya, okungenza ubuso be-root cone kanye nobuso bokuguquka kwezimpande zamazinyo. Futhi ukushelela ngokweqile phakathi kwezinsika zamazinyo kunciphisa amathuba okugxiliswa kwengcindezi kugiya, kunciphisa ukujiya kobuso bamazinyo (kungafinyelela ku-Ra≦0.6um) futhi kuthuthukise ukunemba kokukhomba kwegiya (kungafinyelela ukunemba kwebanga le-GB3∽5). Ngale ndlela, amandla okuthwala igiya kanye nekhono lobuso bamazinyo lokumelana nokunamathela kungathuthukiswa.

4). Igiya le-bevel eliyi-spiral tooth spiral elisetshenziswa yiKlingenberg ezinsukwini zokuqala linozwelo oluphansi ephutheni lokufakwa kwegiya kanye nokuguquguquka kwebhokisi legiya ngoba umugqa wamazinyo ohlangothini lobude bamazinyo awuthinteki. Ngenxa yezizathu zokukhiqiza, lolu hlelo lwamazinyo lusetshenziswa kuphela kwezinye izinkambu ezikhethekile. Nakuba umugqa wamazinyo kaKlingenberg manje usuyi-epicycloid ende, futhi umugqa wamazinyo wohlelo lwamazinyo lweGleason uyisicaba, kuzohlala kukhona iphuzu emigqeni emibili yamazinyo ehlangabezana nezimo zomugqa wamazinyo ongathinteki. Amagiya aklanywe futhi acutshungulwa ngokwesistimu yamazinyo eKinberg, "iphuzu" emgqeni wezinyo elihlangabezana nesimo se-involute liseduze nengxenye enkulu yamazinyo egiya, ngakho-ke ukuzwela kwegiya ephutheni lokufakwa kanye nokuguqulwa komthwalo kuphansi kakhulu, ngokusho kukaGerry Ngokusho kwedatha yobuchwepheshe yenkampani iSen, ngegiya le-spiral bevel eline-arc tooth line, igiya lingacutshungulwa ngokukhetha ikhanda lokusika elinobubanzi obuncane, ukuze "iphuzu" emgqeni wezinyo elihlangabezana nesimo se-involute litholakale endaweni ephakathi nendawo kanye nengxenye enkulu ebusweni bezinyo. Phakathi, kuqinisekiswa ukuthi amagiya anokumelana okufanayo namaphutha okufaka kanye nokuguqulwa kwebhokisi njengegiya leKling Berger. Njengoba i-radius yekhanda lokusika lokulungisa amagiya e-Gleason arc bevel anokuphakama okulinganayo incane kunaleyo yamagiya e-machining bevel anemingcele efanayo, "iphuzu" elihlangabezana nesimo se-involute lingaqinisekiswa ukuthi litholakala phakathi kwendawo ephakathi nendawo kanye nengxenye enkulu ebusweni bezinyo. Phakathi nalesi sikhathi, amandla nokusebenza kwegiya kuyathuthukiswa.

5). Esikhathini esidlule, abanye abantu babecabanga ukuthi uhlelo lwamazinyo lweGleason lwegiya elikhulu le-module lwaluphansi kunohlelo lwamazinyo lweKinberg, ikakhulukazi ngenxa yezizathu ezilandelayo:

1. Amagiya aseKlingenberg ayakhuhlwa ngemva kokwelashwa ngokushisa, kodwa amazinyo okuncipha acutshungulwa amagiya aseGleason awaqedwa ngemva kokwelashwa ngokushisa, futhi ukunemba akukuhle njengokwakuqala.

②. Irediyasi yekhanda lokusika lokucubungula amazinyo okuncipha inkulu kuneyamazinyo e-Kinberg, futhi amandla egiya mabi kakhulu; noma kunjalo, irediyasi yekhanda lokusika enamazinyo ayindilinga e-arc incane kuneyamazinyo okucubungula okuncipha, okufana namazinyo e-Kinberg. Irediyasi yekhanda lokusika elenziwe ilingana.

③. I-Gleason yayivame ukuncoma amagiya ane-modulus encane kanye nenani elikhulu lamazinyo lapho ububanzi begiya bufana, kuyilapho igiya le-Klingenberg elikhulu lisebenzisa i-modulus enkulu kanye nenani elincane lamazinyo, futhi amandla okugoba egiya ancike kakhulu ku-modulus, ngakho-ke i-gram Amandla okugoba e-Limberg makhulu kunalawo e-Gleason.

Njengamanje, ukwakheka kwamagiya kusebenzisa indlela kaKleinberg, ngaphandle kokuthi umugqa wezinyo ushintshwa kusuka ku-epicycloid ende uye ku-arc, futhi amazinyo ayagaywa ngemva kokwelashwa ngokushisa.
