Kev txheeb xyuas ntawm cov khoom sib cais thiab cov kev xav tau ntawm kev ua haujlwm

Raws li ib feem tseem ceeb hauv kev ua haujlwm mechanical, kev xaiv cov khoom sivbearingsncaj qha cuam tshuam nws kev ua tau zoo. Cov khoom siv coj los siv sib txawv ntawm ib daim teb mus rau lwm qhov. Cov hauv qab no yog cov ncauj lus kom ntxaws tsom xam ntawm kev faib tawm thiab kev ua tau zoo ntawm cov khoom siv feem ntau siv.

 

1. Cov khoom siv hlau

Cov kabmob alloy: suav nrog tin matrix thiab txhuas matrix, nrog kev ua haujlwm zoo heev, tsim nyog rau kev thauj khoom siab, tab sis tus nqi siab dua.

Copper alloys: suav nrog tin bronze, aluminium bronze thiab txhuas bronze, haum rau kev ua haujlwm ib puag ncig nyob rau hauv kev sib txawv ceev thiab thauj khoom.

 

Cam khwb cia hlau: haum rau lub teeb load, qis ceev tej yam kev mob.

 

2. Cov khoom siv hlau ntxeem tau

Cov khoom no yog sintered los ntawm cov hmoov hlau sib txawv thiab yog tus kheej-lubricating. Nws yog tsim rau du thiab shock-free loads thiab me me mus rau nruab nrab ceev tej yam kev mob.

 

3. Cov khoom siv tsis yog hlau

Nws feem ntau suav nrog cov yas, roj hmab thiab nylon, uas muaj cov yam ntxwv ntawm kev sib txhuam coefficient ntawm kev sib txhuam, hnav tsis kam thiab corrosion kuj, tab sis muaj peev xwm tsis tshua muaj peev xwm thiab yooj yim rau deformed los ntawm tshav kub.

 

Cov khoom siv bearing kev ua tau zoo:

Friction compatibility: Tiv thaiv adhesion thiab ciam lubrication, uas yog cuam tshuam los ntawm ntau yam, xws li muaj pes tsawg leeg, lubricants, thiab microstructure.

Embeddedness: Tiv thaiv cov khoom tawv los ntawm kev nkag mus thiab ua rau khawb lossis puas.

Khiav-hauv: Txo kev sib txhuam thiab hnav tus nqi los ntawm kev txo cov machining yuam kev thiab qhov chaw roughness parameter qhov tseem ceeb.

Kev sib txhuam ua raws: Lub elastoplastic deformation ntawm cov khoom them nyiaj rau qhov tsis zoo pib haum thiab kev hloov pauv ntawm ncej.

 

Abrasion resistance: Muaj peev xwm tiv taus hnav thiab tsim kua muag.

Fatigue resistance: Lub peev xwm los tiv thaiv qaug zog kev puas tsuaj nyob rau hauv cyclic loads.

Corrosion kuj: muaj peev xwm tiv taus corrosion.

Cavitation tsis kam: Lub peev xwm los tiv thaiv cavitation hnav.

Compressive zog: muaj peev xwm tiv taus ib-txoj kev loads yam tsis muaj deformation.

Dimensional stability: Lub peev xwm los tswj qhov tseeb qhov tseeb ntawm kev siv mus ntev.

Anti-xeb: Nws muaj kev ua haujlwm zoo los tiv thaiv xeb.

Cov txheej txheem kev ua tau zoo: Kho kom haum rau cov kev xav tau ntawm ntau yam txheej txheem kub thiab txias, nrog rau kev tsim, kev ua haujlwm thiab kev kho cua sov.

Cov saum toj no yog ib qho kev ntsuam xyuas dav dav ntawm kev faib tawm ntawm cov khoom siv uas nquag siv thiab lawv cov kev ua tau zoo.
