Ukugaya izinyo Gleason kanye Skiving of Kinberg izinyo

Uma inani lamazinyo, i-modulus, i-engeli yokucindezela, i-engeli ye-helix kanye nerediyasi yekhanda lokusika zifana, amandla e-arc contour amazinyo amazinyo e-Gleason namazinyo e-cycloidal contour yase-Kinberg ayafana. Izizathu zimi kanje:

1). Izindlela zokubala amandla ziyefana: I-Gleason ne-Kinberg bazenzele ezabo izindlela zokubala amandla zamagiya e-spiral bevel, futhi bahlanganise isofthiwe ehambisanayo yokuhlaziya ukwakheka kwegiya. Kodwa bonke basebenzisa ifomula ye-Hertz ukubala ukucindezeleka kokuxhumana kwendawo yezinyo; sebenzisa indlela ye-tangent engama-degree angu-30 ukuze uthole ingxenye eyingozi, wenze umthwalo usebenze ethiphuni lezinyo ukuze ubale ingcindezi yokugoqa impande yezinyo, futhi usebenzise igiya eliyisilinda elilinganayo lengxenye yephoyinti eliphakathi nendawo ukuze ulinganise Bala amandla okuxhumana kwezinyo, Amazinyo anamandla okugoba aphezulu kanye nokumelana nendawo yezinyo ekuxhumekeni kwamagiya e-spiral bevel.

2). Uhlelo lwendabuko lwamazinyo lwe-Gleason lubala imingcele engenalutho yegiya ngokuya ngemodulus yobuso bokuphela kwesiphetho esikhulu, njengobude bethiphu, ukuphakama kwempande yezinyo, nokuphakama kwezinyo elisebenzayo, kuyilapho uKinberg ebala igiya elingenalutho ngokwemodulus evamile ye indawo emaphakathi. ipharamitha. Idizayini yakamuva ye-Agma gear design ihlanganisa indlela yokuklama ye-spiral bevel gear engenalutho, futhi amapharamitha angenalutho egiya aklanywa ngokwemodulus evamile ye-midpoint yamazinyo egiya. Ngakho-ke, kumagiya we-helical bevel anemingcele efanayo eyisisekelo (njenge: inombolo yamazinyo, i-midpoint evamile modulus, i-midpoint helix angle, i-angle yokucindezela evamile), kungakhathaliseki ukuthi hlobo luni lomklamo wezinyo olusetshenziswayo, isigaba esivamile se-midpoint Ubukhulu ngokuyisisekelo kuyafana; futhi amapharamitha wegiya elilinganayo le-cylindrical esigabeni esimaphakathi ayaguquguquka (amapharamitha wegiya elilingana ne-cylindrical ahlobene kuphela nenani lamazinyo, i-pitch angle, i-angle yokucindezela evamile, i-midpoint helix angle, ne-midpoint yendawo yezinyo igiya. Ububanzi bendilinga ye-pitch buhlobene), ngakho-ke amapharamitha womumo wezinyo asetshenziswa ekuhloleni amandla ezinhlelo zamazinyo amabili ayafana.

3). Uma amapharamitha ayisisekelo egiya afana, ngenxa yomkhawulo wobubanzi bomsele ongezansi wezinyo, irediyasi yekhona lethiphu yethuluzi incane kunaleyo yomklamo wegiya le-Gleason. Ngakho-ke, i-radius ye-arc eyeqile yempande yamazinyo incane kakhulu. Ngokusho kokuhlaziywa kwegiya nolwazi olusebenzayo, ukusebenzisa irediyasi enkulu ye-arc yekhala yethuluzi kungakhuphula irediyasi ye-arc eyeqile yempande yamazinyo futhi kuthuthukise ukumelana nokugoba kwegiya.

Ngoba ukunemba komshini wamagiya e-Kinberg cycloidal bevel kungaklwejwa kuphela ngezinyo eliqinile, kuyilapho amagiya e-Gleason ayindilinga e-arc bevel angacutshungulwa ngokugaya kwangemuva okushisayo, okukwazi ukubona i-root cone kanye nendawo yokuguquka kwezinyo. Futhi ukushelela ngokweqile phakathi kwendawo yezinyo kunciphisa amathuba okugxilisa ingcindezi egiyeni, kunciphisa ubulukhuni bendawo yamazinyo (ingafinyelela ku-Ra≦0.6um) futhi kuthuthukise ukunemba kwenkomba yegiya (lingafinyelela ukunemba kwebanga le-GB3∽5) . Ngale ndlela, umthamo wokuthwala wegiya kanye nekhono lendawo yezinyo ukumelana ne-gluing kungathuthukiswa.

4). Igiya le-quasi-involute tooth spiral bevel elitholwe ngabakwaKlingenberg ezinsukwini zakuqala linozwela oluncane ephutheni lokufakwa kwegiya elipheya kanye nokonakala kwebhokisi legiya ngenxa yokuthi umugqa wezinyo obheke kubude bezinyo awuhlangene. Ngenxa yezizathu zokukhiqiza, lolu hlelo lwamazinyo lusetshenziswa kuphela kwezinye izinkambu ezikhethekile. Nakuba umugqa wezinyo we-Klingenberg manje usuyi-epicycloid enwetshiwe, futhi umugqa wezinyo we-Gleason tooth system uyi-arc, liyohlale likhona iphuzu emigqeni yamazinyo emibili elenelisa izimo zomugqa wamazinyo we-involute. Amagiya aklanywe futhi acutshungulwa ngokuvumelana nesistimu yezinyo le-Kinberg, "iphuzu" emugqeni wezinyo elenelisa isimo se-involute liseduze nokuphela okukhulu kwamazinyo egiya, ngakho-ke ukuzwela kwegiya iphutha lokufaka kanye nokuguqulwa komthwalo kukhulu kakhulu. iphansi, ngokusho kukaGerry Ngokusho kwedatha yezobuchwepheshe yenkampani yakwaSen, igiya le-bevel elivunguzayo elinomugqa wezinyo le-arc, igiya lingacutshungulwa ngokukhetha ikhanda lokusika elinobubanzi obuncane, ukuze "iphuzu" emgqeni wezinyo elihlangabezana nesimo se-involute litholakala phakathi nendawo kanye nokuphela okukhulu kwendawo yezinyo. Phakathi, kuyaqinisekiswa ukuthi amagiya anokumelana okufanayo namaphutha okufakwa kanye nokonakala kwebhokisi njengegiya leKling Berger. Njengoba irediyasi yekhanda lokusika lomshini amagiya e-Gleason arc bevel anobude obulinganayo incane kunaleyo yokwenza amagiya e-bevel anamapharamitha afanayo, “iphuzu” elenelisa isimo se-involute lingaqinisekiswa ukuthi litholakala phakathi kwendawo emaphakathi nendawo enkulu. ukuphela kwendawo yezinyo. Ngalesi sikhathi, amandla nokusebenza kwegiya kuyathuthukiswa.

5). Esikhathini esedlule, abanye abantu babecabanga ukuthi isistimu yezinyo ye-Gleason yegiya lemojuli enkulu yayingaphansi kwesistimu yezinyo yaseKinberg, ikakhulukazi ngenxa yalezi zizathu ezilandelayo:

①. Amagiya e-Klingenberg ayakhunyulwa ngemva kokwelashwa kokushisa, kodwa amazinyo anciphayo acutshungulwa amagiya e-Gleason awaqediwe ngemva kokwelashwa kokushisa, futhi ukunemba akukuhle njengakuqala.

②. I-radius yekhanda lokusika lokucubungula amazinyo e-shrinkage inkulu kunamazinyo e-Kinberg, futhi amandla egiya mabi kakhulu; kodwa-ke, i-radius yekhanda lokusika elinamazinyo ayindilinga ayindilinga incane kunaleyo yokucubungula amazinyo anciphayo, afana namazinyo e-Kinberg. Irediyasi yekhanda lokusika elenziwe liyalingana.

③. I-Gleason yayivame ukutusa amagiya anemodulus encane kanye nenani elikhulu lamazinyo lapho ububanzi begiya bufana, kuyilapho igiya le-Klingenberg elikhulu-modulus lisebenzisa i-modulus enkulu nenani elincane lamazinyo, futhi amandla okugoba egiya ancike ikakhulukazi. kumoduli, ngakho igremu Amandla okugoba e-Limberg makhulu kunalawo e-Gleason.

Njengamanje, ukwakheka kwamagiya ngokuyisisekelo kusebenzisa indlela ka-Kleinberg, ngaphandle kokuthi umugqa wezinyo uyashintshwa usuka ku-epicycloid enwetshiwe ube i-arc, futhi amazinyo ayagaywa ngemva kokwelashwa kokushisa.
