Nrog rau cov kev xav tau ntawm kev xav tau, ntau thiab ntau cov khoom siv hauv cov bearings yuav siv cov bearing steel, xws li cov pob steel, steel rings, thiab lwm yam. Niaj hnub no, peb lub teb chaws kuj tau ua qee yam kev sib tw hauv high-end bearing steel. Nws yog tus kheej txaus thiab tseem tuaj yeem xa tawm, uas yuav yog ib qho kev pab rau peb lub teb chaws cov khoom siv high-end bearing. Tab sis ntau tus neeg tseem tsis paub tias qhov zoo ntawm cov khoom siv steel yog dab tsi?
Cov khoom siv bearing - tsib qhov zoo ntawm cov kabmob steel:
1. Hu rau lub zog qaug zog
Nyob rau hauv qhov kev txiav txim ntawm cyclic loads, bearings yog nquag ua rau qaug zog kev puas tsuaj ntawm qhov chaw sib cuag, uas yog, tawg thiab tev, uas yog lub ntsiab kev puas tsuaj daim ntawv ntawm bearings. Yog li ntawd, txhawm rau txhim kho lub neej kev pabcuam ntawm cov kabmob, cov kabmob steel yuav tsum muaj kev sib cuag siab zog.
2. Hnav tsis kam
Thaum cov kabmob ua haujlwm, tsis tsuas yog dov kev sib txhuam tab sis kuj zawv zawg kev sib txhuam tshwm sim ntawm cov nplhaib, dov cov ntsiab lus thiab tawb, ua rau tsis tu ncua ntawm cov kabmob. Txhawm rau txo qhov hnav ntawm cov kabmob, tswj cov kabmob raug thiab ruaj khov, thiab txuas ntxiv kev pabcuam lub neej, cov kabmob steel yuav tsum muaj kev hnav zoo.
3. Hardness
Hardness yog ib qho tseem ceeb ntawm cov kabmob thiab muaj kev cuam tshuam ncaj qha rau kev tiv thaiv qaug zog, hnav tsis kam thiab elastic txwv. Lub hardness ntawm bearing steel nyob rau hauv kev siv tej yam kev mob feem ntau yuav tsum tau mus txog HRC61 ~ 65, thiaj li hais tias cov bearings yuav tau txais kev sib cuag siab qaug zog zog thiab hnav tsis kam.
4. Anti-xeb kev ua tau zoo
Txhawm rau tiv thaiv cov kabmob thiab cov khoom tiav los ntawm kev corroded thiab xeb thaum ua, cia thiab siv, cov kabmob steel yuav tsum muaj cov khoom zoo los tiv thaiv xeb.
5. Kev ua haujlwm zoo
Thaum lub sij hawm tsim cov txheej txheem, bearing qhov chaw yuav tsum mus los ntawm ntau yam txias thiab kub txheej txheem. Yuav kom ua tau raws li qhov yuav tsum tau muaj me me, kev ua haujlwm siab thiab zoo, cov kabmob steel yuav tsum muaj cov khoom ua haujlwm zoo. Piv txwv li, txias thiab kub sib sau zog, txiav kev ua tau zoo, hardenability, thiab lwm yam.
