Gear zvinhu uye kugadzirisa maitiro

Mukuona kwemamiriro azvino, kuyedza uku kunoshandisa 20CrMo simbi sechinhu chekuyedza chekuyedza kwekuedzesera.

Maitiro ekuita ndeaya: kurapwa kwekupisa (carburizing uye kudzima), kupisa kupisa (kuchengetedza kupisa) kutonhodza kwekukanganisa kwemeno (hobi, kuumba magiya). Iyo chaiyo nzira iri seinotevera: mushure mekutanga-kumisikidza uye kubhowa kwema20CrMo magiya, carburizing, yakakwira-frequency induction kudziya kune AC3 (875) austenitizing tembiricha, kukurumidza mafuta kutonhora kusvika 150-250, kunyatsoita mumafuta anopisa, extrusion Iyo vhiri repurasitiki rinokanganisa pamusoro pezino kusvika kune saizi yekupedzisira, uye mupumburu wapera. Kana iyo workpiece ichiri mune austenitic state, iyo workpiece inoburitswa kunze ndokukurumidza kutonhodzwa kuita yakaoma martensite chimiro pane iro zino pamusoro.

Kutanga, hukama pakati pezino kona uye chinzvimbo cheiyo meshing inotorwa.
Iyo inotenderera inofa uye iyo yekushandira giya yakagadzirirwa kuve yakajairwa kumisikidza, uye magiya emazino anotenderedzwa achipikisana nepasi pekutyaira pasi pekutyaira kweanokungura mazino kufa. Chinzvimbo chemutsara wakatyoka wemazino mumufananidzo wakaiswa panzvimbo isina kwachakarerekera, uye kona kona j1 inogadzirwa apo mazino anotsauka kubva pachinzvimbo ichi.
Panzvimbo isina kwazvakarerekera j1 = 0, j1 kukosha kwakakosha kana mazino abviswa nenzira inopesana newachi kuremekedza chinzvimbo chisina kwachakarerekera, uye kukosha kwakashata kana wachi yakatsauswa. 

Nyaya yemeshing poindi kuruboshwe kuruboshwe yakafanana.
Unogona kunyora hukama pakati peimwe nzvimbo paramende
Right flank: j1=j1/20-j1(1)
Left flank: j1=i1-0-j1/2(2)
Iko j1 = arccos (rb1 / rj1) (3)
J1=s1/r1-2(invj1-inv0)(4)
Further derivation jj1=j1-j1/2(5)
Xj1 = rj1cos (j1 / 2)
-r2F- (tf / 2) 2 (6)
Zvinoenderana nehuremu hwekukosha kweiyo zino kutenderera kona, inogona kuzivikanwa kubva pane fomula iri pamusoro apa kuti hukama pakati pej1 nejj1 uye rj1 hwakasarudzika zvakasarudzika.

Nenzira imwecheteyo, hukama pakati pe1 ne1, ri1 kuruboshwe zino panogona kuwanikwa. Muchokwadi, i1 = j1. Naizvozvo, sekureba sekunge j1 yakapihwa, iwo mamosheni eeshinginongedzera ini uye j yemazino ekushandira kuruboshwe uye kurudyi meshing mitsara zvakatemwa zvizere. Uye zvakare, iyo j-poindi pane inozungunuka kufa zino ine meshing denderedzwa redhiyo rj2 = rb22j22 (7) apo rb2 ndiyo denderedzwa redenderedzwa rerino rinotenderera kufa zino;

J2 ndiyo nharaunda yekukombama panongedzo j pane anotenderera kufa mazino. 

Naizvozvo, chinzvimbo chejojo ​​j pane ari anokungurusa muforoma mazino anogona kutemwa nefomula, uye inoenderana nzvimbo parameter senge jj2, xj2 uye j2 dzinowanikwa.
Zvinoenderana neiyo Hertz elastic elastic deformation theory, the elastic deformation amount at the meshing point je = 115FfBE (10) Iyo yeplastiki deformation huwandu Sp hweiyo workpiece zino pamusoro penzvimbo yekubata inogona kuverengerwa neslip mutsara wemunda dzidziso. Sp103 = jFjkB2bjFjkBcj (11) Iripiko nharaunda yakabatanidzwa yekukomberedza kwenzvimbo mbiri dziri padanho rekuita j.
Ipapo huwandu hwese hwekushomeka j panzvimbo yej pane zino inogona kuratidzwa seinotevera fomula j = jjijeSp2 (12) apo 2 ndiyo deformation inokwenenzverwa panzvimbo yejino pamusoro peinozungunuka kufa, uye nzira yekuverenga iyo yakasununguka deformation yeiyo workpiece zino Izvo zvakaenzana; Iko kune yekumusoro yekufambisa cheni pakati pekuumburuka chakuvhe uye yekushandira giya, uye kana iri yenguva dzose yepakati nzvimbo yekutsikirira nzira, yakajairwa yakazara deformation huwandu j = S0 iri yakatarwa kukosha, uko S0 ndiko kuburitsa pamwe nemeshing mutsara nhungamiro. .
Kutora iyo 20CrMo carburized giya inoshandiswa zvakanyanya muindasitiri yemotokari uye chaiyo michina maturusi semuenzaniso, bepa iri rinopa yakanaka roll deformation kupisa kurapwa maitiro ayo anosanganisa kupisa kurapwa, kupeta kwakanaka uye kudzimisa kuita imwechete online kugadzira maitiro, uye inosimbisa roll. Iyo miviri-mativi meshing simba modhi yemazino panguva yeiyo extrusion maitiro anoshandiswa kuwana iyo yekuverenga mafomula eelastic kukotama deformation, yakasununguka kusangana deformation uye yakazara zino deformation yekuumburuka kufa uye yekushandira.
