Cov yam ntxwv ntawm cov tooj liab bearings

Copper bearing yog ib qho tseem ceeb ntawm cov khoom siv dav siv hauv cov cuab yeej siv tshuab. Nws yog tsuas yog siv los nqa cov kev sib hloov ntawm cov ncej, txo kev sib txhuam, muab lubrication thiab kev txhawb nqa. Nws feem ntau yog ua los ntawm tooj liab alloy (xws li txhuas bronze, tin bronze, thiab lwm yam), nrog zoo hnav tsis kam, corrosion kuj thiab siab load peev. Cov yam ntxwv ntawm cov kabmob tooj liab feem ntau suav nrog cov hauv qab no:

1. Khoom siv

Copper bearing feem ntau yog ua los ntawm tooj liab alloy, feem ntau yog:

Aluminium bronze: muaj kev hnav zoo, corrosion kuj thiab kub tsis kam, haum rau siab load.

Tin bronze: muaj zoo hnav tsis kam, corrosion kuj thiab muaj zog lub zog, haum rau nruab nrab thiab siab load tej yam kev mob.

Lead bronze: haum rau qis ceev, hnyav load thiab loj vibration zaus, vim nws muaj nws tus kheej lubrication.

2. Hnav-resistant txheej thiab cov qauv tsim

Copper bearing feem ntau suav nrog ntau txheej txheej, feem ntau nrog cov tawv tawv dua hnav-tiv taus thiab cov txheej softer:

Hnav-resistant txheej: Cov txheej no feem ntau yog tsim los ntawm tooj liab alloy nws tus kheej los yog txheej txheej nrog lwm yam alloying ntsiab lus, muaj zog hnav tsis kam thiab corrosion kuj.

Matrix txheej: Lub matrix ntawm tooj liab bearing yog tooj liab alloy, uas muaj zoo plasticity thiab tsis tshua muaj kev sib txhuam coefficient.

3. Lubrication zawj tsim

Qhov saum npoo ntawm cov kabmob tooj liab feem ntau yog tsim los nrog lubrication grooves (tseem hu ua roj grooves lossis roj raws) rau khaws cia thiab faib cov roj lubricating. Kev tsim cov grooves no tuaj yeem txo qhov kev sib txhuam zoo, txo qhov kub thiab txias, thiab txhim kho cov nyhuv lubrication, ncua kev pab cuam lub neej ntawm cov kabmob.

4. Kev tiv thaiv kev qaug dab peg

Cov kabmob feem ntau yog tsim los nrog qee qhov "qhov sib txawv" los xyuas kom meej tias muaj qhov chaw txaus thaum lub sijhawm teeb tsa kom cov roj lubricating tuaj yeem nkag mus rau ntawm cov kabmob thiab cov ncej los tsim cov roj zaj duab xis los tiv thaiv kev sib cuag hlau ncaj qha, yog li txo qis hnav thiab qaug dab peg.

5. Load-bearing muaj peev xwm thiab elasticity

Cov khoom ntawm tooj liab bearing muaj peev xwm zoo load-bearing thiab tseem muaj peev xwm tswj tau txaus elasticity thiab durability thaum khiav nyob rau hauv siab load, uas yog tshwj xeeb tshaj yog ib qho tseem ceeb rau lub load ntawm loj shafts.

6. Thaum tshav kub kub dissipation muaj peev xwm

Cov khoom siv tooj liab muaj cov thermal conductivity zoo, uas pab cov bearings kom zoo dissipate tshav kub thiab tswj qhov kub kom haum thaum khiav ntawm kev kub ceev kom tsis txhob muaj kev puas tsuaj rau cov kabmob vim overheating.

7. Corrosion kuj

Copper alloys muaj ntuj corrosion kuj, tshwj xeeb tshaj yog rau txhua yam khoom siv hauv dej lossis tshuaj lom neeg. Vim muaj tshuaj lom neeg ruaj khov ntawm tooj liab, bearings tuaj yeem tiv taus qhov chaw ua haujlwm hnyav.

8. Self-lubrication (nyob rau hauv tej yam tshwj xeeb tsim)

Qee cov tooj liab alloy bearings kuj tau tsim los ua tus kheej lubricating, los ntawm cov khoom siv tshwj xeeb los yog sib ntxiv ntawm cov khoom me me kom ua tiav cov roj lubrication mus sij hawm ntev thiab txo kev cia siab ntawm cov khoom siv sab nraud.

Cov ntsiab lus

Cov yam ntxwv ntawm cov kabmob tooj liab feem ntau yog tshwm sim hauv lawv cov khoom siv (tooj liab alloy), hnav tsis kam, zoo lubrication, tsim nyog cov cua sov dissipation tsim thiab corrosion kuj. Los ntawm cov qauv tsim no, nws tuaj yeem txo kev sib txhuam, txuas ntxiv lub neej kev pabcuam thiab muab kev ua haujlwm ruaj khov hauv ntau yam khoom siv.
