Niƙa na Gleason hakori da Skiving na Kinberg hakori

Lokacin da adadin hakora, modulus, matsa lamba, kusurwar helix da radius mai yanke kai iri ɗaya ne, ƙarfin haƙoran haƙoran haƙoran haƙoran Gleason da haƙoran haƙoran cycloidal na Kinberg iri ɗaya ne. Dalilan sune kamar haka:

1). Hanyoyi don ƙididdige ƙarfin iri ɗaya ne: Gleason da Kinberg sun ƙirƙiri hanyoyin lissafin ƙarfin nasu don karkatattun kayan aikin bevel, kuma sun haɗa software na nazarin ƙirar kayan aiki daidai. Amma dukkansu suna amfani da dabarar Hertz don ƙididdige damuwa na lamba na saman hakori; Yi amfani da hanyar tangent na digiri 30 don nemo sashin haɗari, sanya nauyin aiki akan tip ɗin haƙori don ƙididdige damuwa na lanƙwasa tushen haƙori, kuma yi amfani da kayan aikin silinda daidai na sashin tsakiyar haƙori don ƙididdige ƙarfin hulɗar haƙori, babban lankwasawa haƙori da juriya saman haƙori ga gluing na karkace bevel gears.

2). Tsarin haƙori na Gleason na gargajiya yana ƙididdige sigogin gear mara kyau bisa ga ƙarshen fuska na ƙarshe na babban ƙarshen, kamar tsayin tip, tsayin tushen haƙori, da tsayin haƙori mai aiki, yayin da Kinberg yana ƙididdige gear mara kyau bisa ga al'ada modulus tsakiyar batu. siga. Sabuwar ƙirar ƙirar Agma gear tana haɓaka hanyar ƙira ta karkace bevel gear blank, kuma an ƙirƙira sigogin blank ɗin gear bisa ga madaidaicin matsakaicin matsakaicin haƙoran gear. Don haka, ga gears ɗin bevel na helical tare da sigogi iri ɗaya (kamar: adadin hakora, matsakaicin matsakaicin matsakaicin matsakaici, kusurwar helix na tsakiya, kusurwar matsa lamba na al'ada), komai irin ƙirar haƙori da aka yi amfani da shi, sashin al'ada na tsakiya. asali iri daya; kuma ma'auni na daidaitattun kayan aiki na cylindrical a sashin tsakiya sun kasance daidai (ma'auni na daidaitattun kayan aiki na cylindrical suna da alaƙa kawai da adadin hakora, kusurwar farar fata, kusurwar matsa lamba na al'ada, kusurwar helix na tsakiya, da tsakiyar tsakiya na haƙorin haƙori na hakora). Gear. Diamita na da'irar farar yana da alaƙa), don haka sigogin sifar haƙori da aka yi amfani da su a cikin ƙarfin duba tsarin haƙora guda biyu suna da asali iri ɗaya.

3). Lokacin da ma'auni na asali na kayan aiki iri ɗaya ne, saboda ƙayyadaddun nisa na haƙori na kasa, radius na kusurwa na tip kayan aiki ya fi na Gleason gear zane. Saboda haka, radius na wuce gona da iri na tushen hakori yana da ƙananan ƙananan. Dangane da nazarin kayan aiki da ƙwarewar aiki, yin amfani da radius mafi girma na baka na kayan aiki na kayan aiki na iya ƙara radius na wuce kima na tushen haƙori da haɓaka juriya na kayan aiki.

Saboda madaidaicin machining na Kinberg cycloidal bevel gears za a iya goge shi kawai tare da saman haƙora mai wuya, yayin da Gleason madauwari arc bevel za a iya sarrafa ta ta thermal post-nika, wanda zai iya gane tushen mazugi surface da hakori tushen canji surface. Kuma yawan santsi tsakanin haƙoran haƙora yana rage yuwuwar haɗuwa da damuwa akan kayan aiki, yana rage ƙarancin haƙori (zai iya kaiwa Ra≦0.6um) kuma yana haɓaka daidaiton ƙirar kayan aiki (zai iya kaiwa GB3∽5 daidaiton sa). . Ta wannan hanyar, ana iya haɓaka ƙarfin ɗaukar kayan aiki da ƙarfin haƙoran haƙora don tsayayya da gluing.

4). Kayan haƙoran haƙoran da Klingenberg ya ɗauka a farkon kwanakin yana da ƙarancin hankali ga kuskuren shigarwa na nau'in gear da nakasar akwatin gear saboda layin haƙori a cikin hanyar tsayin haƙori ba shi da ƙima. Saboda dalilai na masana'antu, ana amfani da wannan tsarin haƙori ne kawai a wasu fannoni na musamman. Ko da yake layin hakori na Klingenberg yanzu ya zama excycloid mai tsawo, kuma layin hakori na tsarin hakori na Gleason shine arc, koyaushe za a sami maki akan layukan hakori guda biyu wanda ya dace da yanayin layin hakori. Gears da aka tsara da kuma sarrafa su bisa ga tsarin hakori na Kinberg, "ma'ana" a kan layin hakori wanda ya dace da yanayin rashin daidaituwa yana kusa da babban ƙarshen hakoran hakora, don haka hankali na kayan aiki zuwa kuskuren shigarwa da nakasar kaya yana da yawa. low, bisa ga Gerry Dangane da bayanan fasaha na kamfanin Sen, don karkace bevel gear tare da layin hakori na baka, ana iya sarrafa kayan ta hanyar zaɓar shugaban mai yankewa tare da ƙaramin diamita, don haka "ma'ana" akan layin hakori wanda ya sadu da yanayin rashin daidaituwa yana samuwa a tsakiya da babban ƙarshen saman haƙori. A tsakanin, an tabbatar da cewa gears suna da juriya iri ɗaya ga kurakuran shigarwa da nakasar akwatin kamar gear Kling Berger. Tunda radius na mai yankan kai don sarrafa Gleason arc bevel gears tare da tsayi daidai ya yi ƙasa da wancan don sarrafa kayan aikin bevel tare da sigogi iri ɗaya, "ma'ana" wanda ya dace da yanayin rashin daidaituwa za'a iya ba da tabbacin kasancewa tsakanin tsakiya da babba. karshen hakora surface. A wannan lokacin, ana inganta ƙarfin da aikin kayan aiki.

5). A da, wasu mutane suna tunanin cewa tsarin haƙoran Gleason na babban kayan aikin ya yi ƙasa da tsarin haƙorin Kinberg, galibi saboda dalilai masu zuwa:

①. Ana goge gear ɗin Klingenberg bayan maganin zafi, amma raguwar haƙoran da Gleason gears ke sarrafawa ba a gama su ba bayan maganin zafi, kuma daidaito bai kai na farko ba.

②. Radius na mai yanke kai don sarrafa hakoran hakora ya fi girma fiye da na hakora Kinberg, kuma ƙarfin kayan aiki ya fi muni; duk da haka, radius na yankan kai tare da hakoran baka na madauwari ya fi na aikin sarrafa hakora, wanda yayi kama da na Kinberg hakora. Radius na yankan kan da aka yi daidai ne.

③. Gleason ya kasance yana ba da shawarar gears tare da ƙaramin modulus da adadi mai yawa na haƙora yayin da diamita na gear ya kasance iri ɗaya, yayin da Klingenberg manyan-modulus gear yana amfani da babban modulus da ƙananan hakora, kuma ƙarfin lanƙwasa na kayan ya dogara ne akan galibi. akan modules, don haka gram Ƙarfin lanƙwasawa na Limberg ya fi na Gleason girma.

A halin yanzu, ƙirar gears ta ɗauki hanyar Kleinberg, sai dai cewa an canza layin haƙori daga tsayayyen epicycloid zuwa baka, kuma haƙoran suna ƙasa bayan maganin zafi.
