Kev siv linear ncej tau dhau los ua neeg nyiam, tab sis nrog ntau thiab ntau daim ntawv thov, qee qhov teeb meem nrog linear ncej yuav inevitably tshwm sim. Qee tus neeg hais tias cov kab hluav taws xob yuav dhau los thaum siv. Qhov xwm txheej, qhov xwm txheej no yuav tsis tsuas yog cuam tshuam rau kev pabcuam lub neej ntawm cov ncej linear, tab sis kuj txo qhov toughness ntawm cov khoom thiab txo qhov cuam tshuam. Peb yuav daws tau qhov xwm txheej zoo li cas? Peb yuav tsum xub to taub qhov overheating ntawm linear ncej yog vim li cas!
Peb yuav tsum txiav txim seb lub linear ncej yog overheated. Koj tuaj yeem soj ntsuam seb lub microstructure ntawm linear ncej tom qab quenching yog overheated los ntawm roughness ntawm cov kabmob. Txawm li cas los xij, yog tias koj xav txiav txim kom meej, koj tseem yuav tsum tau saib xyuas cov txheej txheem microstructure. Yog hais tias tuab acicular martensite tshwm nyob rau hauv lub quenched qauv ntawm GCr15 steel, nws yog ib tug quenched superheated qauv.
Qhov tshwm sim ntawm overheating phenomenon ntawm linear ncej tej zaum yuav tshwm sim los ntawm lub quenching cua sov kub yog siab dhau heev lawm los yog cua sov thiab tuav lub sij hawm ntev heev; nws kuj tseem yuav yog cov qauv qub band-zoo li carbides hnyav, ua rau qis -carbon cheeb tsam ntawm ob pawg los tsim cov koob martensite hauv zos-xws li ntxhib Local overheating los ntawm.
Txhawm rau kom ntseeg tau tias kev sib khi ua tau zoo, txoj hauv kev ib txwm yog txhawm rau muab cov khoom sib khi rau qhov kev txhawb nqa ntawm txoj kab ncaj nraim. Qhov no tuaj yeem tiv thaiv cov khoom txawv teb chaws los ntawm kev nkag mus, tab sis cov cuab yeej txuas ntxiv no tseem nyob ib feem ntawm qhov chaw thiab ua rau qhov loj me ntawm cov kab tawm. Nqa tsis yooj yim rau kev siv, installation thiab txij nkawm.
There is another shortcoming of the method of adding a sealing device to the support of the linear shaft, that is, the sealing performance is also affected by the machining accuracy and positioning tolerance of the shaft diameter and the matching part of the housing. Therefore, the traditional sealing method of the linear shaft is imperative. For the use of linear shaft, there are still many advantages, but when purchasing and using, we must pay attention to the quality of linear shaft. High-quality linear shaft has advantages in all aspects of performance and is durable. Okay, that's it for today's sharing. For inquiries about linear optical axes, please email us!
