Lisebelisoa tsa Gear le ts'ebetso ea ts'ebetso

Ka lebaka la boemo ba hajoale, teko ena e sebelisa tšepe ea 20CrMo e le lisebelisoa tsa liteko bakeng sa liteko tsa ho etsisa.

Tsela ea ts'ebetso ke: kalafo ea mocheso (ho chesa metsi le ho tima), ho chesa ho chesang (ho boloka mocheso) ho futhumatsa meno a meno (ho tsuba, ho bopa likoloi). Ts'ebetso e ikhethileng e tjena: kamora ho etsa mechini ea pele le ho ts'oara likoloi tsa 20CrMo, carburizing, ho futhumatsa ha maqhubu a phahameng ho AC3 (875) mocheso o matlafatsang, ho futhumatsa oli ka potlako ho 150-250, ho nepahala ka oli e chesang, extrusion Lebili le holofala bokaholimo ba leino ho isa boholo ba ho qetela, mme moqolo o felile. Ha mosebetsi o ntse o le maemong a austenitic, mosebetsi o ntšoa kahare ebe o pholisoa ka potlako ho theha sebopeho se thata sa martensite holim'a leino.

Taba ea mantlha, kamano e teng lipakeng tsa leino la leino le boemo ba meshing e tsoa.
The rolling die and the workpiece gear are be to standard standard, and the gear meno are rotated counterclockwise under under driving of rolling meno die. Boemo ba mola o robehileng oa meno setšoantšong bo behiloe boemong ba ho se jele paate, 'me ho hlaha angle j1 ha meno a kheloha boemong bona.
Boemong ba ho se nke lehlakore j1 = 0, j1 ke boleng bo nepahetseng ha meno a khelositsoe ka lehlakoreng le leng ho ea ka boemo ba ho se nke lehlakore, le boleng bo fosahetseng ha o kheloha ka lehlakoreng le leng. 

Taba ea ntlha ea meshing ka lehlakoreng le letšehali ea tšoana.
E ka ngola kamano lipakeng tsa boemo bo bong le bo bong ba maemo
Right flank: j1=j1/20-j1(1)
Left flank: j1=i1-0-j1/2(2)
Moo 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)
Ho ea ka boleng ba boleng ba leqhubu la potoloho ea meno, ho ka tsejoa ho tloha ka foromo e kaholimo hore kamano lipakeng tsa j1 le jj1 le rj1 e ikemiselitse ka mokhoa o ikhethileng.

Ka mokhoa o ts'oanang, likamano lipakeng tsa i1 le ii1, ri1 ka leino le letšehali le tsona li ka fumaneha. Ebile, i1 = j1. Ka hona, ha feela ho fanoa ka j1, maemo a meshing a supa le j ea meno a sebetsang ka lehlakoreng le letšehali le le letona la meshing a ikemiselitse ka botlalo. Ntle le moo, j-ntlha ho leino le shoang le ntseng le bilika e na le radius ea meshing selikalikoe rj2 = rb22j22 (7) moo rb2 e leng radius ea selikalikoe sa leino le shoang le bilikang;

J2 ke sebaka sa ho kobeha ho ntlha j ho meno a shoang a phallang. 

Ka hona, boemo ba ntlha ea j ho meno a hlobo a phallang bo ka khethoa ke foromo, mme maemo a tšoanang a boemo joalo ka jj2, xj2 le j2 a fumanoa.
Ho latela khopolo-taba ea ho itšireletsa ea Hertz elasticity, palo ea 'mele ea "deform" e sebakeng sa meshing point je = 115FfBE (10) Palo ea polasetiki ea Sp ea leino le sebetsang sebakeng sa puisano e ka baloa ke khopolo-taba ea tšimo. Sp103 = jFjkB2bjFjkBcj (11) E hokae radius e kopaneng ea ho kobeha ha libaka tse peli tse ka lehlakoreng moo ho lebeletsano j.
Ebe palo e felletseng ea deformation j sebakeng sa j leino e ka hlahisoa e le foromo e latelang j = jjijeSp2 (12) moo 2 e leng deformation e rekereng ntlheng ea lejoe la leino la lefu, le mokhoa oa ho bala le deformation deformation ea leino la mosebetsi o lekanang; ho na le ketane ea phetisetso ea kahare lipakeng tsa hlobo e sarolohang le sesebelisoa sa tšebetso, 'me molemong oa mokhoa o sa fetoheng oa ho tobetsa hole, setsi se tloaelehileng sa deformation j = S0 ke boleng bo sa fetoheng, moo S0 e leng extrusion tseleng ea mola oa meshing .
Ho nka lisebelisoa tsa 20CrMo carburized tse sebelisoang haholo indastering ea likoloi le lisebelisoa tse nepahetseng tsa mochini joalo ka mohlala, pampiri ena e etsa tlhahiso ea ts'ebetso e ntle ea kalafo ea mocheso e kopanyang kalafo ea mocheso, ho phethola hantle le ho tima mochini o le mong oa ts'ebetso ea inthanete, mme e theha moqolo. Moetso oa meno a mabeli a mahlakore a mabeli nakong ea ts'ebetso ea extrusion o sebelisetsoa ho fumana litlatsetso tsa lipalo tsa deformation e kobehang, ho ikopanya le ho ikopanya le leino ho senyeha ha leino la sethala se sarolohang le tšebetso.
