Lub neej kev pab cuam ntawm lub sprocket yog luv luv, uas yog deb ntawm ua tau raws li qhov yuav tsum tau ntawm kev xyaum ntau lawm. Raws li kev siv cov txheej txheem ntawm lub sprocket, kev ua haujlwm, thiab kev tsim cov cuab yeej siv, qee qhov kev txhim kho yog npaj rau lub sprocket:
(1) Cov khoom siv sprocket qub yog 40Cr, tag nrho quenching thiab tempering hardness yog HB220250, thiab cov hniav yog quenched HRC4852. Txoj kev no yeej tsis tuaj yeem txhim kho qhov hnav tsis kam ntawm sprocket vim qhov txwv hardness ntawm cov hniav quenching. Nws raug nquahu kom hloov cov khoom siv sprocket rau 20CrMnTi, carburizing thiab quenching kev kho mob, cov saw socket hardness tuaj yeem ncav cuag HRC60 lossis ntau dua, thiab nws hnav tsis kam yog ntau dua 2.5 npaug ntawm cov khoom siv 40Cr. Qhov no tuaj yeem ua rau kom muaj kev pabcuam lub neej ntawm sprocket, txo qhov zaus ntawm kev kho tshuab, ua kom cov khoom tsim tau, thiab txo cov nqi tsim khoom;
(2) Cov duab ntawm tus thawj sprocket sprocket socket yog forged thiab ncaj qha tsim. Nyob rau hauv txoj kev no, qhov yuam kev loj yog qhov loj, qhov saum npoo yog ntxhib, thiab hnav tsis kam kuj raug txo. Nrog rau kev siv dav hauv CNC tshuab cov cuab yeej thiab txo lawv cov nqi ua haujlwm, nws raug nquahu kom tawm ntawm cov npoo me ntsis tom qab forging, thiab ua tiav qhov tiav los ntawm milling los txhim kho qhov tseeb qhov tseeb thiab qhov roughness, thiaj li ua tiav lub hom phiaj ntawm kev txhim kho. hnav tsis kam.
