Cov hniav nto ntawm lubiavyuav tsum muaj kev tiv thaiv siab rau hnav, pitting corrosion, kua nplaum thiab yas deformation, thiab cov hauv paus hniav yuav tsum muaj kev tiv thaiv siab rau kev tawg. Yog li ntawd, cov kev cai yooj yim rau kev ua tau zoo ntawm cov khoom siv hniav iav yog: cov hniav nto yuav tsum tawv thiab cov hniav yuav tsum tawv.
Cov khoom siv iav feem ntau yog hlau, cam khwb cia hlau thiab cov khoom tsis yog xim hlau.
1. Forged hlau
Steel has good toughness and impact resistance. It can also improve its mechanical properties and tooth surface hardness through heat treatment or chemical heat treatment, so it is most suitable for manufacturing gears. Except that the size is too large (da>400 "60mmn) los yog cov qauv nyuaj, nws tsuas yog tsim rau cov casters. Feem ntau, cov iav yog ua los ntawm forged steel, thiab cov hlau uas muaj cov ntsiab lus carbon ntawm (0.15 txog 0.6) Feem ntau yog siv los yog hlau alloy.
Lub forged steel rau kev tsim cov iav tuaj yeem muab faib ua:
Mos hniav nto (hardness<350hs): forged="" steel="" used="" for="" gears="" that="" cut="" teeth="" after="" heat="" treatment.="" for="" gears="" that="" do="" not="" require="" high="" strength,="" speed,="" and="" accuracy,="" they="" should="" be="" used="" to="" facilitate="" tooth="" cutting="" and="" prevent="" the="" tool="" from="" wearing="" down="" quickly.="" therefore,="" the="" gear="" blank="" should="" be="" normalized="" (normalized)="" or="" quenched="" and="" tempered="" to="" cut="" the="" teeth.="" after="" cutting,="" it="" is="" the="" finished="" product.="" its="" precision="" is="" generally="" 8="" grades,="" and="" it="" can="" reach="" 7="" grades="" when="" fine="" cutting.="" such="" gears="" are="" easy="" to="" manufacture,="" economical="" and="" have="" high="" production="">
Hard tooth surface (hardness>350HES: lub ntsiab iav kis tau tus mob siv nyob rau hauv high-ceev, hnyav-load thiab precision tshuab (xws li precision tshuab cuab yeej, aero engines) forged steel zog, ntxiv rau yuav tsum tau zoo heev cov khoom siv, high-lub zog iav hniav ntxiv rau lub siab hardness ntawm tus hniav nto (xws li 58 ~ 65HRC), nws yuav tsum tau ua zoo machining xws li sib tsoo. Feem ntau cov iav uas yuav tsum tau ua kom tiav yog tam sim no txiav cov hniav ua ntej, tom qab ntawd nto hardening kev kho mob, thiab thaum kawg ua tiav, precision tuaj yeem ncav cuag 5 qib lossis qib 4. Hom iav no muaj qhov siab precision thiab kuj kim, yog li cov txheej txheem kho cua sov muaj xws li nto quenching. , carburizing, nitriding, mos nitriding, thiab cyanidation. Yog li ntawd, cov khoom siv nyob ntawm qhov kev xav tau tshwj xeeb thiab kev kho cua sov.
Alloy steel tuaj yeem txhim kho qhov toughness, cuam tshuam tsis kam, hnav tsis kam thiab tiv thaiv kev ua haujlwm ntawm cov khoom siv raws li qhov muaj pes tsawg leeg thiab kev ua haujlwm ntawm cov hlau muaj. kev kho mob lossis tshuaj kho cua sov. . Yog li ntawd, rau high-ceev, hnyav-lub luag hauj lwm, aerospace zog uas yuav tsum tau me me thiab loj loj, lawv tag nrho cov yog ua los ntawm hlau alloy nrog kev ua tau zoo heev (xws li 20CrliTi, 20Cr2N1i4, thiab lwm yam).
2. Cam khwb cia hlau
Kev hnav tsis kam thiab lub zog ntawm cov cam khwb cia hlau yog zoo dua, tab sis yuav tsum tau annealed thiab normalized, thiab tuaj yeem tempered yog tias tsim nyog. Cam khwb cia hlau feem ntau yog siv rau cov iav loj.
3. Cam khwb cia hlau
Grey cam khwb cia hlau yog nkig thiab muaj kev cuam tshuam tsis zoo thiab hnav tsis kam, tab sis nws muaj kev tiv thaiv zoo rau gluing thiab pitting corrosion. Grey cam khwb cia hlau iav feem ntau yog siv nyob rau hauv cov xwm txheej uas kev ua haujlwm ruaj khov, qhov ceev yog tsawg, thiab lub zog tsis loj.
4. Cov khoom siv tsis yog hlau
Rau kev kub ceev lub teeb-load thiab tsawg-precision iav kis tau tus mob, thiaj li yuav txo tau suab nrov, cov ntaub ntawv uas tsis yog-hlau (xws li ntaub paj hlwb, nylon, thiab lwm yam.) feem ntau yog siv raws li lub zog me me, thiab lub zog loj tseem ua los ntawm cov hlau. los yog cam khwb cia hlau. Txhawm rau ua kom cov iav loj muaj kev tiv thaiv kev hnav thiab pitting tsis kam, qhov hardness ntawm cov hniav yuav tsum yog 250 ~ 350HBS.
