Cov kev pabcuam lub neej ntawm sprocket yog luv luv, uas nyob deb ntawm qhov ua tau raws li cov cai ntawm kev coj ua. Raws li kev siv tus txheej txheem sprocket, kev ua cov xwm txheej, thiab kev siv thev naus laus zis, qee qhov kev txhim kho raug tsim kho rau tus sprocket:
(1) tus qauv tsim sprocket qub yog 40Cr, tag nrho quenching thiab tempering hardness yog HB220 ~ 250, thiab cov hniav txhawm quenched HRC48 ~ 52. Txoj kev no tsis tuaj yeem txhim kho qhov hnav tsis kam ntawm sprocket vim qhov txwv tsis tshua muaj siab ntawm tus hniav quenching. Nws raug nquahu kom hloov cov khoom siv sprocket mus rau 20CrMnTi, carburizing thiab quenching kho, qhov nyuaj ntawm cov saw hlau muaj peev xwm ncav cuag HRC60 lossis ntau dua, thiab nws hnav tsis zoo dua li 2.5 npaug ntawm 40Cr khoom. Qhov no tuaj yeem ua kom zoo dua kev pab cuam lub neej ntawm sprocket, txo cov zaus ntawm kev kho kom zoo dua qub, nce khoom lag luam, thiab txo tus nqi tsim khoom;
(2) Cov duab ntawm lub qhov taub sprocket thawj qhov (socket) yog forged thiab tsim ncaj qha, yog li qhov yuam kev me me yog qhov loj, qhov saum npoo yog ntxhib, thiab hnav tsis kam kuj txo. Nrog rau kev thov dav ntawm CNC tshuab cov cuab yeej thiab kev txo qis ntawm lawv cov nqi, nws raug pom zoo kom tawm ntawm cov npoo me ntsis tom qab forging thiab tag machining los ntawm milling los txhim kho qhov ntev qhov tseeb thiab qhov saum npoo tawv, yog li ua tiav lub hom phiaj txhim kho hnav tsis kam.
