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 ukubala ingcindezi yokugoba impande yezinyo, futhi usebenzise igiya elilingana ne-cylindrical lengxenye ye-tooth surface midpoint ukuze ulinganise Bala amandla okuxhumana nezinyo, amandla okugoba aphezulu kanye nokumelana nezinyo ebusweni ukuze kuxhunywe amagiya e-bevel.

2). Isistimu yezinyo le-Gleason evamile ibala imingcele engenalutho yegiya ngokuya ngemodulus yobuso bokuphela kwesiphetho esikhulu, njengobude bethiphu, ukuphakama kwempande yezinyo, nobude bezinyo elisebenzayo, kuyilapho i-Kinberg ibala igiya elingenalutho ngokwemodulus evamile yephoyinti eliphakathi. 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 (njengokuthi: inombolo yamazinyo, i-midpoint evamile modulus, i-midpoint helix angle, i-angle yokucindezela evamile), kungakhathaliseki ukuthi hlobo luni lomklamo wezinyo olusetshenzisiwe, isigaba esivamile se-midpoint Ubukhulu bufana ngokuyisisekelo; futhi amapharamitha wegiya elilinganayo le-cylindrical esigabeni esimaphakathi ayaguquguquka (amapharamitha wegiya lesilinda elilinganayo ahlobene kuphela nenani lamazinyo, i-pitch angle, i-angle yokucindezela evamile, i-midpoint helix angle, kanye ne-midpoint yendawo yezinyo legiya. Ububanzi bomjikelezo we-pitch buhlobene), ngakho-ke amapharamitha womumo wezinyo asetshenziswa ngokufanayo amapharamitha ayisisekelo asetshenziswayo.

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 kuthuthukisa 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 ngokuya ngohlelo lwamazinyo eKinberg, “iphuzu” emugqeni wezinyo elenelisa isimo se-involute liseduze nesiphetho esikhulu samazinyo egiya, ngakho-ke ukuzwela kwegiya ephutheni lokufakwa nokuguqulwa komthwalo kuphansi kakhulu, ngokusho kukaGerry Ngokusho kwedatha yezobuchwepheshe yenkampani yakwaSen, yegiya le-bevel elivunguzayo elinentambo yezinyo le-arc, ukuze inqubo yokusika ibe yincane igiya. "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 wamagiya e-Gleason arc bevel anobude obulinganayo incane kunaleyo yokwenza amagiya e-bevel anamapharamitha afanayo, “iphuzu” elenelisa isimo se-involute lingaqinisekiswa ukuthi litholakala phakathi kwephoyinti eliphakathi nendawo nendawo enkulu 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 ijwayele ukuncoma amagiya anemodulus encane nenani elikhulu lamazinyo lapho ububanzi begiya bufana, kuyilapho igiya le-Klingenberg elikhulu-modulus lisebenzisa imodulus enkulu nenani elincane lamazinyo, futhi amandla okugoba egiya ancike kakhulu kumodulus, ngakho igremu Amandla okugoba eLimberg makhulu kunalawo eGleason.

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.
