Kuva kumasaha kugeza kuri turbine, ibikoresho byubunini butandukanye, binini na bito, bikoreshwa cyane mubicuruzwa bitandukanye nkibice bya mashini byohereza ingufu.Bavuga ko ingano y’isoko ry’ibikoresho n’ibikoresho byo ku isi bigeze kuri tiriyari imwe y’amafaranga, kandi bikaba biteganijwe ko izakomeza gutera imbere byihuse mu gihe kiri imbere hamwe n’iterambere ry’inganda.
Ibikoresho ni ubwoko bwibikoresho bikoreshwa cyane mubuzima, bwaba indege, imizigo, ibinyabiziga nibindi.Ariko, mugihe ibikoresho byateguwe kandi bigatunganywa, umubare wibikoresho urasabwa.Abantu bamwe bavuga ko niba ari munsi y amenyo 17, ntishobora kuzunguruka., uzi impamvu?
None se kuki 17?Aho kuba indi mibare?Kubijyanye na 17, ibi bitangirana nuburyo bwo gutunganya ibikoresho, nkuko bigaragara ku gishushanyo gikurikira, uburyo bukoreshwa cyane ni ugukoresha hob gukata.
Iyo gukora ibikoresho muri ubu buryo, iyo umubare w amenyo ari muto, kugabanuka gukabije, bigira ingaruka kumbaraga zakozwe.Ibiri munsi bisobanura ko umuzi waciwe...Reba agasanduku gatukura ku ishusho:
None ni ryari dushobora kwirinda kugabanuka?Igisubizo ni iyi 17 (iyo coefficient yuburebure bwinyongera ari 1 naho inguni yumuvuduko ni dogere 20).
Mbere ya byose, impamvu ituma ibyuma bishobora kuzunguruka ni ukubera ko umubano mwiza wo guhererekanya ugomba gushirwaho hagati yibikoresho byo hejuru nibikoresho byo hasi.Gusa iyo guhuza byombi biri mukibanza, imikorere yacyo irashobora kuba umubano uhamye.Gufata ibikoresho birimo urugero, ibyuma bibiri birashobora gukina uruhare rwabo mugihe bihuye neza.By'umwihariko, bagabanijwemo ubwoko bubiri: ibikoresho bya spur na gare.
Kubikoresho bisanzwe bya spur, coefficient yuburebure bwinyongera ni 1, naho coefficient yuburebure bwinyo yinyo ni 1.25, naho inguni yumuvuduko igomba kugera kuri dogere 20.Iyo ibikoresho bitunganijwe, niba iryinyo ryigikoresho nigikoresho kimeze nkibikoresho bibiri Kimwe.
Niba umubare w'amenyo ya urusoro ari munsi yagaciro runaka, hazacukurwa igice cyumuzi wumuzi w amenyo.Niba gukuramo ari bito, bizagira ingaruka kumbaraga no guhagarara neza.17 twavuze hano ni ibikoresho.Niba tutavuze kubyerekeranye nubushobozi bwakazi bwibikoresho, bizakora nubwo amenyo yaba angana gute.
Mubyongeyeho, 17 numubare wambere, nukuvuga, umubare wuzuzanya hagati yinyo runaka yi bikoresho nibindi bikoresho byibuze byibuze kumubare runaka, kandi ntabwo bizahagarara muriki gihe kirekire. iyo imbaraga zikoreshwa.Ibikoresho ni ibikoresho byuzuye.Nubwo hazaba hari amakosa kuri buri bikoresho, amahirwe yo kwambara uruziga rw'ibiziga kuri 17 ni menshi cyane, niba rero ari 17, bizaba byiza mugihe gito, ariko ntibizakora igihe kirekire.
Ariko dore ikibazo!Haracyari ibikoresho byinshi bifite amenyo ari munsi ya 17 kumasoko, ariko aracyahinduka neza, hariho amashusho nukuri!
Bamwe mu bakoresha urubuga bagaragaje ko, mubyukuri, niba uhinduye uburyo bwo gutunganya, birashoboka gukora ibikoresho bisanzwe birimo ibikoresho bitarenze amenyo 17.Birumvikana ko ibikoresho nkibi nabyo byoroshye kwizirika (kubera kubangamira ibikoresho, sinshobora kubona ifoto, nyamuneka fata icyemezo), kubwibyo ntibishobora guhinduka.Hariho kandi ibisubizo byinshi bihuye, kandi ibikoresho byo guhinduranya nibyo bikoreshwa cyane (mubisobanuro byabalayiki, ni ukwimura igikoresho kure mugihe cyo gutema), kandi hariho nibikoresho bya tekinike, ibyuma bya cycloidal, nibindi. Noneho hariho pancycloid ibikoresho.
Ikindi gitekerezo cya netizen: Umuntu wese asa nuwizera ibitabo cyane.Sinzi umubare wabantu bize neza ibikoresho byakazi.Mu isomo ryamahame yubukanishi, ntampamvu yo gutera ibikoresho bya spur birimo amenyo arenga 17.Inkomoko yo gukata ishingiye ku kuba hejuru ya R yuzuye hejuru ya rake isura yigikoresho cya rack yo gutunganya ibikoresho ni 0, ariko mubyukuri, ni gute ibikoresho mubikorwa byinganda bitagira inguni ya R.. amenyo, nuko amenyo 17 akoreshwa nkibintu byimbere.Mubyukuri, irakinguye kugirango tujye impaka!Reka turebe amashusho yavuzwe haruguru.
Birashobora kugaragara uhereye ku gishushanyo ko iyo ibikoresho bikozwe nigikoresho gifite inguni ya R ya 0 hejuru yisura ya rake, umurongo winzibacyuho uva kumenyo ya 15 ukageza kumenyo ya 18 ntabwo uhinduka cyane, none kuki? yavuze ko iryinyo rya 17 ritangirana iryinyo rigororotse?Tuvuge iki ku mubare w'amenyo ari munsi?
Iyi shusho igomba kuba yarashushanijwe nabanyeshuri biga ibijyanye nubukanishi hamwe na Fan Chengyi.Urashobora kubona ingaruka za R inguni yigikoresho kumurongo wibikoresho.
Kuringaniza umurongo wa epicycloid yumutuku wagutse mu mizi yishusho yavuzwe haruguru ni umwirondoro w amenyo nyuma yo gutema imizi.Ni mu buhe buryo igice cyumuzi wibikoresho kizaba munsi kugirango bigire ingaruka kumikoreshereze yacyo?Ibi bigenwa nigikorwa cyo kugereranya iryinyo hejuru yibindi bikoresho hamwe nimbaraga zimbaraga zumuzi w amenyo yibikoresho.Niba iryinyo ryo hejuru ryibikoresho byo gushyingiranwa ridahuye nigice cyo munsi, ibyuma byombi birashobora kuzunguruka bisanzwe, (Icyitonderwa: Igice cyo munsi yacyo ni umwirondoro w amenyo utabigizemo uruhare, hamwe no gushushanya umwirondoro w amenyo utabigizemo uruhare kandi utari- Uruhare rwinyo yinyo mubusanzwe ntabwo ihujwe mugihe cyigishushanyo kidasanzwe, ni ukuvuga kwivanga).
Uhereye kuri iyi shusho, birashobora kugaragara ko umurongo wa meshing wibikoresho byombi umaze guhanagura umuzenguruko ntarengwa wa diametre uhabanye nu murongo uhinduranya wibikoresho byombi (Icyitonderwa: igice cyumutuku ni umwirondoro w amenyo, igice cyumuhondo nicyo munsi igice, umurongo wa meshing Ntibishoboka kwinjira munsi yumuzingi fatizo, kuko ntabigizemo uruhare munsi yumuzingi fatizo, kandi ingingo zo gushingura za gare ebyiri kumwanya uwariwo wose ziri kumurongo), ni ukuvuga, ibyuma byombi birashobora mesh gusa mubisanzwe, birumvikana ko ibi bitemewe mubuhanga, uburebure bwumurongo wa meshing ni 142.2, iyi gaciro / shingiro igice = impamyabumenyi.
Uhereye kuri iyi shusho, birashobora kugaragara ko umurongo wa meshing wibikoresho byombi umaze guhanagura umuzenguruko ntarengwa wa diametre uhabanye nu murongo uhinduranya wibikoresho byombi (Icyitonderwa: igice cyumutuku ni umwirondoro w amenyo, igice cyumuhondo nicyo munsi igice, umurongo wa meshing Ntibishoboka kwinjira munsi yumuzingi fatizo, kuko ntabigizemo uruhare munsi yumuzingi fatizo, kandi ingingo zo gushingura za gare ebyiri kumwanya uwariwo wose ziri kumurongo), ni ukuvuga, ibyuma byombi birashobora mesh gusa mubisanzwe, birumvikana ko ibi bitemewe mubuhanga, uburebure bwumurongo wa meshing ni 142.2, iyi gaciro / shingiro igice = impamyabumenyi.
Abandi bati: Mbere ya byose, gushyiraho iki kibazo ni bibi.Ibyuma bifite amenyo ari munsi ya 17 ntabwo bizagira ingaruka kumikoreshereze (ibisobanuro byiyi ngingo mubisubizo byambere ni bibi, kandi ibintu bitatu byo guhuza neza ibyuma ntaho bihuriye numubare w amenyo), ariko amenyo 17 muri a bimwe Mubihe bimwe byihariye, ntibizoroha gutunganya, hano haribindi byuzuza ubumenyi kubijyanye nibikoresho.
Reka mvuge kubyerekeye kubigiramo uruhare mbere, kubigiramo uruhare ni ubwoko bukoreshwa cyane muburyo bwinyo yerekana amenyo.None se kuki utabigizemo uruhare?Ni irihe tandukaniro riri hagati yuyu murongo n'umurongo ugororotse na arc?Nkuko bigaragara ku gishushanyo gikurikira, ni ukubigiramo uruhare (hano hari kimwe cya kabiri cyinyo kirimo)
Kubishyira mu ijambo rimwe, kubigiramo uruhare ni ugufata umurongo ugororotse hamwe nigitekerezo gihamye kuriwo, iyo umurongo ugororotse uzunguruka uruziga, inzira yumwanya uhamye.Inyungu zayo ziragaragara mugihe bibiri birimo mesh hamwe, nkuko bigaragara mumashusho hepfo.
Iyo ibiziga byombi bizunguruka, icyerekezo gikora cyingufu aho zihurira (nka M, M ') zihora kumurongo umwe ugororotse, kandi uyu murongo ugororotse ubikwa perpendikulari kubice bibiri bifatanye bisa (indege tangent) ).Bitewe no guhagarikwa, ntihazabaho "kunyerera" na "guterana amagambo" hagati yabo, bigabanya intego yo kugabanya imbaraga zo guteranya meshi ya gare, idashobora kuzamura imikorere gusa, ariko kandi ikanongerera ubuzima ibikoresho.
Birumvikana, nkuburyo bukoreshwa cyane muburyo bwo kumenyo yinyo - kubigiramo uruhare, ntabwo aribyo duhitamo byonyine.
Usibye "gukata", nkaba injeniyeri, ntidukeneye gusuzuma gusa niba bishoboka kurwego rwa theoretical kandi niba ingaruka ari nziza, ariko cyane cyane, tugomba gushaka uburyo bwo gukora ibintu bya teoretiki bisohoka, birimo guhitamo ibikoresho , gukora, gutomora, kugerageza, nibindi nibindi.
Uburyo bukoreshwa muburyo bwo gutunganya ibikoresho bigabanijwe muburyo bwo gukora nuburyo bwo gukora abafana.Uburyo bwo gukora ni ugukata neza imiterere yinyo mugukora igikoresho gihuye nuburyo bwo gutandukanya amenyo.Mubisanzwe harimo gusya, gusya ikinyugunyugu, nibindi.;Uburyo bwa Fan Cheng bugereranya Bigoye, urashobora kumva ko ibyuma bibiri birimo gusya, kimwe kikaba gikomeye (icyuma), ikindi kikaba kimeze nabi.Uburyo bwo guswera bugenda buhoro buhoro buva kure cyane bugenda busanzwe.Muri ubu buryo ibikoresho bishya bikozwe no gukata hagati.Niba ubishaka, urashobora kubona "Amahame ya Mikoranike" kugirango wige birambuye.
Uburyo bwa Fancheng burakoreshwa cyane, ariko mugihe umubare w amenyo yi bikoresho ari muto, aho ihuriro ryumurongo winyongera wigikoresho hamwe numurongo wa meshing bizarenga imipaka ntarengwa yibikoresho byaciwe, numuzi wibikoresho bigomba gutunganywa. bizaba birenze Gukata, kubera ko igice cyo munsi kirenze igipimo ntarengwa, ntabwo bigira ingaruka kumashanyarazi asanzwe, ariko ibibi nuko bigabanya imbaraga z amenyo.Iyo ibikoresho nkibi bikoreshwa mugihe kiremereye cyane nka bokisi, Biroroshye kumena amenyo.Ishusho yerekana icyitegererezo cyibikoresho 2-bipfa 8-amenyo nyuma yo gutunganywa bisanzwe (hamwe na undercut).
Kandi 17 numubare ntarengwa w amenyo ubarwa ukurikije ibikoresho byigihugu cyacu.Ibikoresho bifite umubare w amenyo ari munsi ya 17 bizagaragara "undercutting phenomenon" mugihe bisanzwe bitunganijwe nuburyo bwa Fancheng.Muri iki gihe, uburyo bwo gutunganya bugomba guhindurwa, nko kwimurwa, nkuko bigaragara ku gishushanyo cya 2-bapfa 8-amenyo y’ibikoresho byakozwe kugirango berekane (munsi ya undercut).
Nibyo, byinshi mubirimo byasobanuwe hano ntabwo byuzuye.Hariho ibindi bice byinshi bishimishije muri mashini, kandi hariho ibibazo byinshi mugukora ibi bice mubuhanga.Abasomyi bashimishijwe barashobora kwifuza kwitondera cyane.
Umwanzuro: Amenyo 17 ava muburyo bwo gutunganya, kandi biterwa nuburyo bwo gutunganya.Niba uburyo bwo gutunganya ibikoresho bwasimbuwe cyangwa bwanonosowe, nkuburyo bwo gukora uburyo bwo gutunganya no kwimura ibintu (hano bivuga cyane cyane ibyuma byihuta), ibintu bitagaragara ntibizabaho, kandi ntakibazo gihari kumubare w amenyo 17.
