Kev tshuaj xyuas ntawm kev faib tawm cov khoom siv thiab kev ua tau zoo

Raws li ib qho tseem ceeb hauv kev ua haujlwm mechanical, kev xaiv cov khoom siv ntawmcov kabmobcuam ​​tshuam ncaj qha rau nws txoj kev ua tau zoo. Cov ntaub ntawv siv rau kev coj tus kheej sib txawv ntawm ib qho chaw mus rau lwm qhov. Cov hauv qab no yog kev tshuaj xyuas ntxaws ntxaws ntawm kev faib tawm thiab kev ua tau zoo ntawm cov ntaub ntawv siv feem ntau.

 

1. Cov ntaub ntawv hlau

Cov khoom siv bearing: suav nrog tin matrix thiab lead matrix, nrog kev ua tau zoo heev, tsim nyog rau cov xwm txheej siab, tab sis tus nqi siab dua.

Cov hlau tooj liab: suav nrog tin bronze, aluminium bronze thiab lead bronze, tsim nyog rau cov chaw ua haujlwm nyob rau hauv ntau qhov ceev thiab cov xwm txheej thauj khoom.

 

Hlau cam khwb cia: tsim rau lub teeb thauj khoom, qhov ceev qis.

 

2. Cov ntaub ntawv hlau uas muaj qhov ntxeem tau

Cov khoom siv no yog sintered los ntawm ntau hom hmoov hlau thiab nws tus kheej lubricating. Nws yog tsim rau cov khoom thauj du thiab tsis muaj kev co thiab cov xwm txheej me me mus rau nruab nrab ceev.

 

3. Cov ntaub ntawv tsis yog hlau

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

 

Cov kev cai ntawm kev ua haujlwm ntawm cov khoom siv:

Kev sib txhuam sib xws: Tiv thaiv kev lo thiab kev nplua nplua ciam teb, uas cuam tshuam los ntawm ntau yam, suav nrog cov khoom sib xyaw, cov roj nplua nyeem, thiab cov qauv me me.

Kev Sib Txuas: Tiv thaiv cov khoom tawv kom tsis txhob nkag mus thiab ua rau khawb lossis puas.

Kev khiav hauv: Txo qhov kev sib txhuam thiab kev hnav los ntawm kev txo cov kev ua yuam kev thiab cov nqi ntawm qhov roughness ntawm qhov chaw.

Kev ua raws li kev sib txhuam: Qhov elastoplastic deformation ntawm cov khoom siv them rau qhov tsis zoo thaum pib haum thiab qhov yooj ywm ntawm tus ncej.

 

Kev tiv thaiv kev sib txhuam: Lub peev xwm los tiv thaiv kev hnav thiab tsim kua muag.

Kev tiv taus qaug zog: Lub peev xwm los tiv taus kev puas tsuaj qaug zog nyob rau hauv cov khoom thauj cyclic.

Kev tiv thaiv corrosion: Lub peev xwm los tiv thaiv corrosion.

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

Lub zog compressive: Lub peev xwm los tiv taus ib txoj kev thauj khoom yam tsis muaj kev hloov pauv.

Kev ruaj khov ntawm qhov ntev: Lub peev xwm los tswj qhov tseeb ntawm qhov ntev thaum siv mus sij hawm ntev.

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

Kev ua tau zoo ntawm cov txheej txheem: Hloov kho rau qhov xav tau ntawm ntau yam txheej txheem ua kub thiab txias, suav nrog kev ua tau zoo, kev ua tiav thiab kev ua tau zoo ntawm kev kho cua sov.

Qhov saum toj no yog kev tshuaj xyuas dav dav ntawm kev faib tawm ntawm cov ntaub ntawv siv feem ntau thiab lawv cov kev xav tau kev ua tau zoo.
