(1) Carburized maus taus sprockets yuav tsum muaj txheej carburized ntawm tus hniav nto. Thaum cov txheej txheem "carburized-sov extrusion" yog siv, kev faib ntawm carburized txheej yog ze ze rau txoj kev deformation ntawm iav txoj kev. Rau cov txheej txheem tangential phua extrusion, txheej carburized ntawm cov hniav iav yog redistributed los ntawm carburized txheej nyob rau saum npoo ntawm lub cylindrical dawb paug. Nyob rau hauv "carburizing-sov extrusion" txheej txheem ntawm lub zog, lub sij hawm deformation yog luv dua, thiab diffusion ntawm carburized txheej yuav tsis quav ntsej. Obviously, tom qab lub tog raj kheej dhau los ua ib lub iav, qhov chaw saum npoo yog loj heev, thiab cov thickness ntawm carburized txheej hloov tau zoo heev. Thaum lub carburized txheej yog tangentially compressed thaum lub sij hawm tsim txheej txheem, lub thickness ntawm carburized txheej nce, txwv tsis pub, lub thickness yuav txo; thiab txheej carburized Lub thickness hloov nyob ntawm tus nqi ntawm tangential deformation. Yog li ntawd, lub thickness faib ntawm txheej carburized tuaj yeem tswj tau los ntawm kev tswj cov tangential deformation ntawm carburized txheej thaum lub sij hawm sov extrusion ntawm lub iav.
(2) Raws li kev nkag siab txog cov txheej txheem ntawm maus taus sprocket hniav, kev sib tham ntxiv txog kev hloov pauv ntawm carburized txheej ntawm lub tog raj kheej mus rau carburized txheej ntawm cov iav thaum tsim cov iav ib feem: lub tog raj kheej nias los ntawm cov poj niam cov hniav. carburized txheej dhau los ua carburized txheej ntawm iav hauv paus ib feem. Qhov kev hloov pauv yuav tsum yog los ntawm lub tog raj kheej nto mus rau cov hniav hauv paus hniav, thiab qhov ua ntej nws koom nrog qhov deformation, qhov ntau dua tus nqi txuas ntxiv, lub thinner txheej carburized; ntawm qhov tsis sib xws, vim yog qhov tuag extrusion Thaum lub siab ua rau qhov concave ntawm qhov siab ua rau lub hauv paus ntawm cov hniav, cov hlau ntawm qhov siab ntawm qhov tuag ntawm cov hlau thiab qhov radial ntawm cov hlau ua cov hniav crest. ib feem, qhov no ntawm cov hlau yog compressed los ntawm ob tug nyob ib sab tuag cais cov hniav nyob rau saum toj, ces Lub thickness ntawm carburized txheej nce; Thaum lub deformation nce, yog tias qhov kev sib cuag nrog cov poj niam pwm raug kev sib txhuam txaus ntawm cov poj niam pwm, lub thickness ntawm carburized txheej yuav raug txo thaum stretching tshwm sim.
