Kev xaiv cov kua dej bearing yuav tsum coj mus rau hauv tus account bearing muaj peev xwm, abrasion kuj, corrosion kuj thiab tej yam kev mob ntawm kev siv. Cov ntaub ntawv tseem ceeb tuaj yeem muab faib ua pawg hauv qab no:

• Cov khoom siv hlau

Bearing alloys: Raws li cov tin lossis txhuas, cov khoom xws li antimony thiab tooj liab tau ntxiv rau daim ntawv mos alloys. Nws muaj kev sib txhuam zoo txo ​​qhov kev ua tau zoo thiab muaj zog tiv thaiv kev puas tsuaj, thiab tsim nyog rau kev siv siab - nrawm thiab hnav.
Copper-Based Alloys: nrog rau cov hlau lead-bronze thiab tin bronze, tsim los ntawm cov txheej txheem casting lossis hmoov metallurgy. Lawv muaj lub zog siab, zoo thermal conductivity thiab qaug zog tsis kam thiab feem ntau yog siv rau hauv nruab nrab thiab siab ceev hnyav load khoom.
Aluminium alloy: Cov khoom ntawm aluminium alloy yog optimized los ntawm kev kho cov ntsiab lus tin, uas yog haum rau hydrodynamic bearings nyob rau hauv tshwj xeeb ua hauj lwm tej yam kev mob.

Fluid Film Thrust Bearing

• Tsis yog -Cov khoom siv hlau

Engineering plastics: Polytetrafluoroethylene (PTFE) thiab hloov kho polyoxymethylene (POM) muaj tus kheej -lubricating zog thiab tuaj yeem qhuav los ntawm kev ntxig cov khoom lubricating. Haum rau kev khiav hauj lwm qhov chaw nrog kev saib xyuas nyuaj lossis txwv lubrication.
Roj Hmab: Feem ntau yog siv rau cov dej lubrication los yog qias neeg, siv nws elasticity kom hloov mus rau kev vibration thiab poob siab.
Carbon graphite: kub kub, corrosion kuj, tus kheej-lubrication thiab lwm yam khoom, haum rau kub kub los yog tshuaj corrosion ib puag ncig.
Composites: Metallic-Non-metallic Composites: Siv cov hlau matrix uas muaj sintered los yog embedded khoom lubricating khoom (xws li molybdenum disulfide los yog graphite). Qhov no tuav lub peev xwm ntawm cov hlau thaum txo kev sib txhuam coefficient los ntawm cov khoom lubrication txheej.
Powder Metallurgy Materials: tsim los ntawm cov hmoov hlau nias thiab sintering txheej txheem, nrog cov qauv ntxeem tau, tuaj yeem khaws cov roj lubricating lossis cov roj nplua nyeem, tsim nyog rau ciam teb lubrication lossis sib xyaw lubrication.

Q1: Dab tsi yog cov khoom siv tseem ceeb rau Fluid Film Thrust Bearings?
A1: Cov khoom yuav tsum ua raws li cov hauv qab no:

• Load Capacity: hloov mus rau kev kub ceev, hnyav load los yog tej yam kev mob load;
• Hnav tsis kam: Txo kev sib txhuam thiab hnav thaum lub sij hawm ntev - siv;
• Corrosion Resistance: tsis kam rau lubricating roj oxidation khoom lossis ib puag ncig xov xwm corrosion;
• Thermal stability: tswj qhov seem stability thiab txhua yam khoom ntawm qhov kub thiab txias;
• Txheej txheem Adaptability: Ib qho yooj yim casting, hmoov metallurgy los yog txhua yam ua.

Q2: Cov khoom siv bearing tau xaiv li cas raws li kev siv?
A2: Cov txheej txheem xaiv muaj xws li:

• Tsawg ceev, hnyav load: qhov tseem ceeb yog muab rau bearing alloys los yog tooj liab-base alloys coj kom zoo dua ntawm lawv cov kabmob muaj peev xwm thiab cuam tshuam;
• Siab -ceev, lub teeb yuag: Siv aluminium alloys lossis engineering plastics los txo cov quab yuam centrifugal thiab txo cov cua sov tsawg.
• Corrosive ib puag ncig: Xaiv cov carbon graphite lossis corrosion resistant alloy kom tsis txhob muaj tshuaj lom neeg corrosion ua rau tsis ua hauj lwm;
• High -kub tej yam kev mob: xaiv high- kub resistant ceramics los yog tshwj xeeb alloys los xyuas kom meej tias cov khoom tsis soften los yog oxidize nyob rau hauv high kub;
• Cov xwm txheej ntawm kev saib xyuas: siv tus kheej- lubricating composites los txo cov roj lubricating.

Q3: Dab tsi yog qhov zoo ntawm cov khoom sib xyaw hauv hydrodynamic bearings?
A3: Cov ntaub ntawv sib xyaw ua ke sib xyaw ua ke los ntawm kev sib xyaw hlau thiab tsis yog -cov khoom siv hlau:

• Metallic matrix: muab cov qauv muaj zog thiab thermal conductivity, txhawb nqa load, thiab dispersion stress;
• Tsis yog-hlau lubrication txheej: Txo kev sib txhuam coefficient, txo qis hnav thiab kub;
• Porous qauv: cia ntawm cov roj lubricating los yog cov roj lubricating, ua cov yeeb yaj kiab txuas ntxiv;
• Adaptability: Customized yuav tsum tau ua raws li nyob rau hauv txawv kev khiav hauj lwm tej yam kev mob los ntawm kev kho qhov sib piv piv.
