Raws li peb txhua tus paub, muaj ntau yam khoom siv bearing nyob rau hauv kev ua lag luam, thiab peb cov khoom siv bearing muaj xws li peb pawg ntawm cov ntaub ntawv hlau, cov khoom siv hlau ntxeem tau thiab cov khoom tsis yog xim hlau.

Cov khoom siv hlau

Cov kabmob alloy, bronze, aluminium puag alloy, zinc puag alloy thiab lwm yam yog tag nrho cov khoom siv hlau.Ntawm lawv, cov kabmob alloy, tseem hu ua dawb alloy, feem ntau yog cov hlau lead, tin, antimony lossis lwm yam hlau.Nws tuaj yeem muaj lub zog tsawg nyob rau hauv cov xwm txheej ntawm qhov hnyav thiab kev kub ceev.Yog vim li cas yog hais tias nws muaj zoo hnav tsis kam, siab plasticity, zoo khiav hauv kev ua tau zoo, zoo thermal conductivity, zoo kua nplaum kuj thiab zoo adsorption nrog roj.Txawm li cas los xij, vim nws tus nqi siab, nws yuav tsum tau nchuav rau ntawm cov kabmob ntawm bronze, steel sawb lossis cam khwb cia hlau los ua ib txheej nyias.

(1) Bearing alloy (feem ntau hu ua Babbitt alloy lossis dawb alloy)
Bearing alloy yog ib qho alloy ntawm tin, lead, antimony thiab tooj liab.Nws siv cov tin los yog txhuas raws li cov matrix thiab muaj cov nplej tawv tawv ntawm antimony tin (sb SN) thiab tooj liab tin (Cu SN).Cov nplej tawv ua lub luag haujlwm tiv thaiv kev hnav, thaum lub matrix mos tsub kom cov plasticity ntawm cov khoom.Lub elastic modulus thiab elastic txwv ntawm bearing alloy yog tsawg heev.Ntawm tag nrho cov khoom siv bearing, nws Embeddedness thiab kev sib txhuam ua raws li qhov zoo tshaj plaws.Nws yog ib qho yooj yim mus khiav nrog cov phau ntawv journal thiab tsis yooj yim rau tom nrog phau ntawv journal.Txawm li cas los xij, lub zog ntawm cov kabmob alloy yog tsawg heev, thiab cov kabmob bush tsis tuaj yeem ua ib leeg.Nws tsuas tuaj yeem txuas nrog tooj liab, hlau lossis cam khwb cia hlau bearing hav txwv yeem raws li cov kabmob hauv ob sab phlu.Bearing alloy yog tsim rau hnyav load, nruab nrab thiab siab ceev zaus, thiab tus nqi yog kim.

(2) Copper alloy
Copper alloy muaj lub zog siab, zoo antifriction thiab hnav tsis kam.Bronze muaj cov khoom zoo dua li tooj dag thiab yog cov khoom siv feem ntau.Bronze muaj xws li tin bronze, txhuas bronze thiab txhuas bronze.Ntawm lawv, tin bronze muaj qhov zoo tshaj plaws antifrict
