Gear ihe na usoro nhazi

N'ihi ọnọdụ dị ugbu a, nnwale a na-eji nchara 20CrMo mee ihe dị ka ihe nnwale maka nnwale nnwale.

Usoro usoro a bụ: ọgwụgwọ ọkụ (carburizing na quenching), ikpo ọkụ na-ekpo ọkụ (nchekwa ọkụ) jụrụ nke ezé ezé (hobbing, gear shaping). Usoro a kapịrị ọnụ bụ: mgbe arụchara ọrụ na ịmị ọkụ nke 20CrMo gears, carburizing, ọkụ ọkụ ọkụ ọkụ ọkụ AC3 (875) nke na-eme ka ọ dị ọkụ, ngwa ngwa mmanụ dị jụụ na 150-250, nkenke na mmanụ ọkụ, extrusion The wheel plastically deform elu nha nha nke ikpeazu, ma mpiri agwu. Mgbe ihe eji arụ ọrụ ka dị na steeti austenitic, a na-ewepụta ya ma mee ka ọ dị jụụ ngwa ngwa wee mepụta usoro siri ike martensite na ezé ezé.

Nke mbu, enwere mmekorita nke di na onu eze na onodu nke meshing.
The Rolling anwụ na workpiece gia na-ga-ọkọlọtọ echichi, na gia ezé na-agba gburugburu counterclockwise n'okpuru ịnya ụgbọ ala nke Rolling anwụ ezé. Ọnọdụ nke akara agbajiri nke ezé na ọnụ ọgụgụ ahụ ka atọrọ n'ọnọdụ na-anọpụ iche, ma mepụta j1 anya mgbe ezé ga-ahapụ ọnọdụ a.
N'ebe na-anọpụ iche j1 = 0, j1 bụ uru dị mma mgbe ezé ezé na-atụgharị anya na elekere anya n'ihe gbasara ọnọdụ nnọpụiche, yana uru na-adịghị mma mgbe elegharịrị elekere. 

Okwu ikpe meshing isi aka ekpe yiri.
Nwere ike dee mmekọrịta dị n'etiti ọnọdụ ọnọdụ ọ bụla
Right flank: j1=j1/20-j1(1)
Left flank: j1=i1-0-j1/2(2)
Ebe 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)
Dịka uru bara uru nke akụkụ ntụgharị eze ahụ, enwere ike ịmata ya site na usoro dị n'elu na mmekọrịta dị n'etiti j1 na jj1 na rj1 bụ mkpebi pụrụ iche.

Site n'otu ụzọ ahụ, enwere ike nweta mmekọrịta dị n'etiti i1 na ii1, ri1 n'akụkụ elu aka ekpe. N'ezie, i1 = j1. Ya mere, ọ bụrụhaala na e nyere j1, a na-ekpebisi ike ọnọdụ nke meshing points i na j nke ezé workpiece na aka ekpe na aka nri meshing. Na mgbakwunye, j-point na rolling die ezé nwere meshing okirikiri okirikiri rj2 = rb22j22 (7) ebe rb2 bụ isi gburugburu okirikiri nke inyefe anwụ eze;

J2 bụ okirikiri nke curvature na isi j na Rolling anwụ ezé. 

Ya mere, enwere ike ikpebi ọnọdụ nke akara j na ezé ebu mpịakọta site na usoro ahụ, ma nweta ọnọdụ ọnọdụ kwekọrọ dịka jj2, xj2 na j2.
Dị ka Hertz na-agbanwe kọntaktị deformation tiori, na-agbanwe deformation ego na meshing ebe je = 115FfBE (10) The plastic deformation ego Sp nke workpiece nha nha elu na kọntaktị ebe nwere ike gbakọọ site ileghara akara ubi tiori. Sp103 = jFjkB2bjFjkBcj (11) Ebee ka okpokoro okirikiri nke akụkụ abụọ akụkụ ahụ jikọtara ọnụ na njikọ aka j.
Mgbe ahụ ngụkọta deformation ego j na j ebe ke nha nha nwere ike gosipụta dị ka ndị na-esonụ usoro j = jjijeSp2 (12) ebe 2 bụ na-agbanwe mgbanwe na j ebe nke eze nha nha nke Rolling anwụ, na ngụkọta oge usoro na mgbanwe na-agbanwe agbanwe nke ezé arụ ọrụ Otu ego; enwere eriri nnyefe dị n'ime nkuku na-agagharị na ihe eji arụ ọrụ, ma ọ bụrụ na usoro ịpị ebe dị anya, ọnụọgụ nrụrụ nkịtị j = S0 bụ uru bara uru, ebe S0 bụ extrusion tinyere usoro akara akara. .
Na-ewere ihe eji emepụta carcized 20CrMo nke a na-ejikarị eme ihe na ụlọ ọrụ ụgbọala na ngwa ọrụ nkenke dị ka ihe atụ, akwụkwọ a na-atụ aro usoro mpịakọta nrụrụ nrụrụ dị mma nke na-agwakọta ọgwụgwọ ọkụ, ịgbanye na ịgbanye na otu usoro ntanetị n'ịntanetị, ma guzobe mpịakọta. The abụọ-n'akụkụ meshing ike nlereanya nke ezé n'oge extrusion usoro a na-eji na-erite na ngụkọta oge formulas nke na-agbanwe ekwe deformation, na-agbanwe kọntaktị deformation na ngụkọta nha nha nha nke Rolling anwụ na workpiece.
