Impahla ye-Gear nenqubo yokucubungula

Ngenxa yesimo samanje, lesi silingo sisebenzisa i-20CrMo steel njengezinto zokuhlola zokulingisa kokulingisa.

Umzila wenqubo uwukuthi: ukwelashwa kokushisa (i-carburizing kanye nokucima), ukugoqa okushisayo (ukulondolozwa kokushisa) ukupholisa ukuqina kwamazinyo (i-hobbing, i-gear shaping). Inqubo ethile imi kanje: ngemuva kokushaywa kwangaphambili nokuxhunyaniswa kwamagiya angama-20CrMo, ukushisa imoto, ukufudumeza okuvama kakhulu kwe-AC3 (875) izinga lokushisa, ukufudumeza uwoyela ngokushesha kuye ku-150-250, ukucacisa ku-oyela oshisayo, ukukhipha isondo likhubazeka ubuso bezinyo ngosayizi wokugcina, futhi umqulu usuphelile. Lapho okokusebenza kusesesimweni se-austenitic, okokusebenza kuyakhishwa futhi kupholiswe ngokushesha ukwakha isakhiwo se-martensite esinzima emazinyweni.

Okokuqala, ubudlelwane obuphakathi kwe-engeli yamazinyo kanye nesimo se-meshing bususelwa.
I-rolling die kanye ne-workpiece gear kusethelwe ukufakwa okujwayelekile, futhi amazinyo egiya ajikelezwa uphikisana nokuhamba kwewashi ngaphansi kokushayela kwamazinyo e-die rolling. Ukuma kolayini ophukile wamazinyo kulo mfanekiso kusethwe kungathathi hlangothi, futhi i-engeli engaphandle i-j1 yenziwa lapho amazinyo esuka kule ndawo.
Esikhundleni sokungathathi hlangothi j1 = 0, j1 yinani elihle lapho amazinyo ehlanjululwa ngokuphikisana nokuhamba kwewashi maqondana nesimo sokungathathi hlangothi, kanye nenani elibi lapho i-clockwise iphambukisiwe. 

Icala lephoyinti le-meshing ohlangothini lwesobunxele liyafana.
Ingabhala ubudlelwano phakathi kwepharamitha ngayinye yesikhundla
Right flank: j1=j1/20-j1(1)
Left flank: j1=i1-0-j1/2(2)
Lapho i-j1 = arccos (rb1 / rj1) (3)
J1=s1/r1-2(invj1-inv0)(4)
Further derivation jj1=j1-j1/2(5)
I-Xj1 = rj1cos (j1 / 2)
-r2F- (tf / 2) 2 (6)
Ngokwebanga lenani le-engeli yokujikeleza kwamazinyo, kungaziwa kusuka kwifomula engenhla ukuthi ubudlelwane obuphakathi kuka-j1 no-jj1 no-rj1 bunqunywe ngokukhethekile.

Ngendlela efanayo, ubudlelwano phakathi kwe-i1 no-ii1, i-ri1 ebusweni bezinyo langakwesobunxele bungatholakala. Eqinisweni, i1 = j1. Ngakho-ke, inqobo nje uma kunikezwa i-j1, izikhundla zamaphoyinti okugcizelela i no-j wamazinyo okusebenza emigqeni engakwesokunxele nangakwesokudla kunqunywa ngokuphelele. Ngaphezu kwalokho, iphuzu le-j kuzinyo lokufa eligingqikayo lineradiyo yomjikelezo we-meshing rj2 = rb22j22 (7) lapho i-rb2 iyisisekelo sombuthano oyisisekelo sezinyo lokufa eligingqikayo;

I-J2 ingu-radius of curvature ephuzwini j kumazinyo wokufa agingqekayo. 

Ngakho-ke, isikhundla sephuzu le-j kumazinyo wokugoqa ogingqikayo singanqunywa yifomula, futhi nemingcele yesimo ehambisanayo efana ne-jj2, xj2 ne-j2 iyatholakala.
Ngokwe-Hertz elastic elastic deformation theory, the elastic deformation amount at the meshing point je = 115FfBE (10) Inani le-deformation lepulasitiki Sp lendawo yamazinyo womsebenzi endaweni yokuxhumana lingabalwa ngombono wensimu yomugqa oshelelayo. I-Sp103 = jFjkB2bjFjkBcj (11) Ikuphi indawo ehlanganisiwe yokugobeka kwalezi zinhlangothi ezimbili ezinhlangothini lapho kuhlangana khona uj.
Ngemuva kwalokho inani eliphelele le-deformation j endaweni ye-j ezingeni lingabonakaliswa njengefomula elandelayo j = jjijeSp2 (12) lapho i-2 is deformation elastic at the j point of the tooth surface of the rolling die, and the calculation method and ukusonteka okunwebeka kwamazinyo womsebenzi Inani elifanayo; kukhona uchungechunge lokudlulisa lwangaphakathi phakathi kwesikhunta sokugoqa kanye negiya lomsebenzi, futhi esimweni sokucindezela njalo ibanga lesikhungo lendawo, inani elijwayelekile lokuguquguquka j = S0 inani elinqunyiwe, lapho i-S0 ingukukhishwa okuhambisana nesiqondisi somugqa we-meshing .
Ukuthatha i-20CrMo gear carburized esetshenziswa kakhulu embonini yezimoto namathuluzi womshini wokunemba njengesibonelo, leli phepha liphakamisa inqubo enhle yokwelashwa ngokushisa kwe-roll ehlanganisa ukwelashwa kokushisa, ukugoqa okuhle nokucisha inqubo eyodwa yokucubungula online, futhi kusungulwe umqulu. Imodeli yamandla amazinyo anezinhlangothi ezimbili enqubo yenqubo yokukhipha isetshenziselwa ukuthola amafomula wokubala we-deformation eguqulwayo, ukunwebeka kokuxhumana nokunwebeka kanye nokuguqulwa kwamazinyo okuphelele kohlobo lokugoqa kanye nomsebenzi wokusebenzela.
