1 Kev loj hlob zeem muag ntawm yas bearings
Tam sim no, cov neeg siv khoom siv feem ntau tseem tawm tsam ntawm cov kabmob yas thiab hlau thaum xaiv cov kabmob rau lawv cov khoom siv. Tom qab tag nrho, thaum cov yas bearings tseem tsis tau tsim, hlau bearings yeej ib txwm xaiv cov khoom siv, thiab ntau tus neeg tseem tsis kam muab cov khoom siv hlau xaiv. Tab sis txog tam sim no, kev ua haujlwm ntawm cov kabmob yas tau zoo dua thiab zoo dua yav tom ntej.
2 Cov khoom siv yas yas thiab lawv qhov zoo
Qhov tseeb, cov nqi tsim khoom ntawm cov yas yog qis dua li cov hlau bearings, thiab ntau yam ntawm cov ntaub ntawv yas yog nce ntau. Siv nyob rau hauv ntau lub lag luam, cov ntaub ntawv yas feem ntau yog nylon, PTFE, polyethylene thiab PEEK.
Lub versatility, kev lag luam thiab kev huv ntawm cov yas bearings. Muaj ntau yam khoom siv uas tsis muaj nqi rau ntau yam kev siv. Yas bearings feem ntau yog tsim los ntawm cov thermoplastic alloys nrog cov fibers matrix thiab cov khoom siv roj nplua nyeem uas muab lub zog zoo heev thiab tsis tshua muaj coefficient ntawm kev sib txhuam.
3 Cov khoom zoo ntawm cov kabmob yas yog dab tsi?
(1) Lubricating nws tus kheej
Cov yas, los ntawm lawv qhov xwm txheej, lubricate bearings, txo qhov pib qeeb thiab ua kom huv si. Cov khoom me me ntawm cov kabmob hnav tawm thiab ua rau lubricate cov kabmob hauv thawj qhov chaw, tab sis qhov kev hloov pauv ntawm cov kabmob nws tus kheej yog negligible. Qhov no tseem ua rau cov kabmob yas zoo dua rau cov ntawv thov zaub mov, raws li FDA nruj me ntsis txwv kev siv cov roj nplua nyeem hauv cov khoom noj khoom haus. Tsis tas li ntawd, thaum plua plav thiab lwm yam khoom tuaj yeem lo rau cov roj nplua nyeem thiab tsim cov txheej av, nrog cov kabmob yas, cov khoom yuav tsuas ua rau hauv cov kabmob uas tsis muaj kev cuam tshuam rau kev ua haujlwm.
(2) Kev ua haujlwm ntawm qhov kub thiab txias
Yas bearings tuaj yeem ua haujlwm tsis tu ncua ntawm txhua qhov kub ntawm {{0}}} degree thiab 260 degree thiab tuaj yeem tiv taus qhov kub siab tshaj li 600 degree F. Yas bushings tuaj yeem muaj zog li hlau bushings tab sis nrog cov phab ntsa nyias, feem ntau 0.0468 " -0.0625" tuab. Cov phab ntsa nyias yog qhov zoo dua ntawm cov cua sov dissipating, ua rau muaj kev ua haujlwm loj dua thiab hnav tsawg dua. Tsis tas li ntawd, cov phab ntsa nyias nyias yog qhov sib dua thiab tsis tshua muaj deform, ua rau lawv haum rau cov ntawv thov qhov hnyav yog qhov teeb meem.
(3) Kev ua haujlwm ib puag ncig
Yas bearings muaj roj ntau dua vim lawv lub teeb yuag. Yas bearings tsis tas yuav tsum tau coatings ntxiv los yog additives los ua tib yam li cov hlau qhov chaw uas feem ntau supplemented nrog teeb meem. Tsis tas li ntawd, kev tsim cov yas yuav tsum tsuas yog kwv yees li ntawm 10-15 feem pua roj piv rau tib tus nqi ntawm txhuas lossis hlau.
(4) Cov tshuaj tiv thaiv zoo
Yas bearings feem ntau tiv taus ntau yam tshuaj thiab tshuaj ntau dua li cov kabmob hlau, tiv thaiv cov khawb thiab hnav uas tshwm sim nrog cov kabmob hlau. Qhov no pab ua kom lawv cov coefficient ntawm kev sib txhuam qis, txav mus los nrog kev cuam tshuam tsawg.
(5) Kev tu-dawb bearings
Los ntawm kev xaiv cov yas kom raug rau ib puag ncig uas nws yuav siv, cov kabmob yuav tiv taus corrosion dhau sijhawm. Ib zaug ntsia, cov yas bearings muaj lub neej ua haujlwm ntev thiab tsis tas yuav hloov. Corrosion tuaj yeem ua rau cov kabmob hlau khov rau hauv qhov chaw, ua rau lawv yuav luag tsis tuaj yeem tshem tawm yam tsis tau txiav tawm. Yas bearings yog yooj yim tshem tawm.
(6) Tsawg tus nqi ntawm cov yas
Ntau cov yas yog pheej yig dua li cov hlau. Yog li yas bearings thiab yas bushings tuaj yeem txo cov nqi txog li 25 feem pua.
