Njengendlela yokudlulisela, igiya leplanethi lisetshenziswa kakhulu kuzinqubo zobunjiniyela ezihlukahlukene, ezifana nesinciphisi segiya, ukhreyini, isinciphisi segiya leplanethi, njll. Ngokunciphisa amagiya eplanethi, kungangena esikhundleni sendlela yokudlulisela yesitimela se-axle egxilile ezimweni eziningi. Ngoba inqubo yokudlulisa igiya iwukuthintana komugqa, i-meshing yesikhathi eside izodala ukwehluleka kwegiya, ngakho-ke kuyadingeka ukulingisa amandla ayo. U-Li Hongli et al. wasebenzisa indlela ye-othomathikhi ye-meshing ukuhlanganisa igiya leplanethi, futhi bathola ukuthi i-torque kanye nengcindezi enkulu kumugqa. Wang Yanjun et al. iphinde yaxhumanisa igiya leplanethi ngokusebenzisa indlela yokuzenzakalela, futhi yalingisa i-statics nokulingisa i-modal yegiya leplanethi. Kuleli phepha, izakhi ze-tetrahedron ne-hexahedron zisetshenziselwa ikakhulukazi ukuhlukanisa i-mesh, futhi imiphumela yokugcina iyahlaziywa ukuze kubonakale ukuthi izimo zamandla ziyahlangatshezwa yini.

1. Ukusungulwa kwemodeli nokuhlaziywa kwemiphumela

Ukumodela okunezinhlangothi ezintathu kwegiya leplanethi

Imishini yeplanethiihlanganiswe kakhulu negiya leringi, igiya lelanga kanye neplanethi. Imingcele eyinhloko ekhethiwe kuleli phepha yilezi: inani lamazinyo endandatho yegiya langaphakathi lingu-66, inani lamazinyo egiya lelanga lingama-36, inani lamazinyo egiya leplanethi liyi-15, ububanzi bangaphandle begiya langaphakathi. indandatho ingu-150 mm, i-modulus ingu-2 mm, i-angle yokucindezela ingu-20 °, ububanzi bezinyo buyi-20 mm, i-addendum coefficient ingu-1, i-backlash i-coefficient ingu-0.25, futhi kukhona amagiya amaplanethi amathathu.

Ukuhlaziywa kokulingisa okumile kwegiya leplanethi

Chaza izakhiwo zezinto ezibonakalayo: ngenisa isistimu yegiya leplanethi engu-3-dimensional edwetshwe kusofthiwe ye-UG ku-ANSYS, bese usetha amapharamitha wezinto ezibonakalayo, njengoba kukhonjisiwe kuThebula 1 ngezansi:

I-Meshing: I-element mesh enomkhawulo ihlukaniswa nge-tetrahedron ne-hexahedron, futhi usayizi oyisisekelo we-elementi ngu-5mm. Kusukela iizinto zeplanethi, igiya lelanga nendandatho yegiya langaphakathi kuxhumene ne-mesh, i-mesh yezingxenye zokuthintana ne-mesh iminyene, futhi ubukhulu bungu-2mm. Okokuqala, amagridi e-tetrahedral asetshenziswa, njengoba kuboniswe kuMfanekiso 1. Izakhi ze-105906 kanye nama-node angu-177893 akhiqizwa ngokuphelele. Bese kwamukelwa igridi ye-hexahedral, njengoba kukhonjisiwe kuMfanekiso 2, futhi amaseli angu-26957 kanye nama-node angu-140560 akhiqizwa esewonke.

Isicelo sokulayisha kanye nezimo zemingcele: ngokwezici zokusebenza zegiya leplanethi kusinciphisi, igiya lelanga liyigiya lokushayela, igiya leplanethi liyigiya elishayelwa, kanti okokugcina kuphuma ngesithwali seplanethi. Lungisa iringi yegiya langaphakathi ku-ANSYS, bese usebenzisa itorque engu-500N · m egiyeni lelanga, njengoba kuboniswe kuMfanekiso 3.

Ukucubungula okuthunyelwe nokuhlaziywa kwemiphumela: I-nephogram yokugudluzwa kanye nephogram yengcindezi efanayo yokuhlaziywa okumile okutholwe ezingxenyeni ezimbili zamagridi kunikezwa ngezansi, futhi ukuhlaziya okuqhathanisayo kwenziwa. Kusuka ku-nephogram yokususwa kwezinhlobo ezimbili zamagridi, kutholakala ukuthi ukufuduka okuphezulu kwenzeka endaweni lapho igiya lelanga lingahlangani negiya leplanethi, futhi ukucindezeleka okukhulu kwenzeka empandeni ye-gear mesh. Ingcindezi enkulu yegridi ye-tetrahedral ngu-378MPa, futhi ukucindezeleka okukhulu kwegridi ye-hexahedral ngu-412MPa. Njengoba umkhawulo wesivuno sempahla ingu-785MPa futhi isici sokuphepha singu-1.5, ingcindezi evumelekile ngu-523MPa. Ukucindezeleka okukhulu kwemiphumela yomibili kungaphansi kokucindezeleka okuvumelekile, futhi kokubili kuhlangabezana nezimo zamandla.

2, Isiphetho

Ngokulingisa kwesici esinqunyelwe segiya leplanethi, i-nephogram ye-displacement deformation kanye nephogram yengcindezi efanayo yohlelo lwegiya kutholwa, lapho idatha ephezulu nencane kanye nokusatshalaliswa kwayo endaweni.izinto zeplanethiimodeli ingatholakala. Indawo yokucindezela okulingana okuphezulu futhi indawo lapho amazinyo egiya engase ahluleke khona, ngakho-ke ukunakekelwa okukhethekile kufanele kukhokhwe kuyo ngesikhathi sokuklama noma ukukhiqiza. Ngokuhlaziywa kwalo lonke uhlelo lwegiya leplanethi, iphutha elibangelwe ukuhlaziya izinyo legiya elilodwa kuphela liyanqotshwa.
