Kev Xaiv Bearing Uas Nyhav Thiab Zoo: Kev Tshawb Fawb Txog Cov Khoom Siv Yas Engineering Cage

 

Hauv kev dov niaj hnubkev coj uatsim, lub tawb yog ib qho tseem ceeb, thiab kev xaiv cov khoom siv cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov kabmob, lub neej ntev, thiab cov ntawv thov. Piv rau cov ntaub ntawv hlau ib txwm muaj, cov tawb yas engineering maj mam nce qib hauv ntau qhov chaw lag luam vim lawv cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb.

 

Tsab xov xwm no tsom mus rau cov yas engineering mainstream xws linylon (PA), polyoxymethylene (POM), thiab polyimide (PI), tshuaj xyuas lawv cov txiaj ntsig kev ua tau zoo thiab cov ciam teb siv tau hauv cov ntawv thov tawb.

 

Kev Sib Piv Txog Kev Ua Haujlwm ntawm Cov Khoom Siv Tseem Ceeb

 

Nylon (PA)

 

Vim nws qhov kev tawv zoo heev, kev ua kom nws tus kheej lubrication, thiab qhov zoo ntawm tus nqi, nylon yog siv dav hauv cov bearings ua haujlwm hauv qab qhov nruab nrab thiab qhov kub nruab nrab. Nws cov coefficient qis ntawm kev sib txhuam pab txo cov suab nrov ua haujlwm, ua rau nws tsim nyog rau cov khoom siv hauv tsev thiab cov khoom siv hauv chaw ua haujlwm uas xav tau kev ntsiag to siab. Raws li Phau Ntawv Qhia Txog Kev Siv Rolling Bearing, PA66 muaj qhov kub ua haujlwm tas mus li txog li 120 ° C thiab tuaj yeem tiv taus qhov kub luv luv txog li 150 ° C. Nws tus nqi PV (siab × qhov ceev) yog kwv yees li 50 MPa·m / s, ua rau nws tsim nyog rau kev ua haujlwm nruab nrab ceev.

 

Polyoxymethylene (POM)

 

POM paub txog nws qhov kev tawv siab, qis qis, thiab kev ruaj khov zoo heev. Nws qhov chaw du thiab kev tiv taus hnav zoo dua li nylon ua rau nws tsim nyog rau kev tuav cov tawb hauv kev kub ceev, lub teeb-load, lossis cov cuab yeej siv precision. POM muaj qhov kub ua haujlwm ntawm -40 ° C txog 100 ° C, nrog rau kev ua haujlwm luv luv txog li 120 ° C. Nws tus nqi PV tuaj yeem ncav cuag 60 MPa · m / s, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov cav ceev ceev thiab cov tshuab wiper tsheb.

 

Polyimide (PI)

 

Ua tus sawv cev ntawm cov yas engineering ua tau zoo, PI muaj kev tiv taus kub zoo heev (txog li 260 ° C rau kev siv ntev) thaum tswj hwm lub zog kho tshuab zoo thiab tiv taus hluav taws xob. Nws tus nqi PV tuaj yeem tshaj 100 MPa·m / s, ua rau nws tsim nyog rau cov chaw ib puag ncig hnyav xws li aerospace, lub cev muaj zog kub siab, thiab cov kabmob hauv cov khoom siv nqus tsev. Txawm hais tias nws tus nqi siab dua, nws tsis tuaj yeem hloov pauv hauv cov xwm txheej ua haujlwm tshwj xeeb.

 

Cov Kev Zoo Tag Nrho ntawm Engineering Yas Cages

 

Lub teeb yuag: Nrog qhov ceev tsuas yog ib feem xya ntawm cov hlau, yas txo qhov hnyav tag nrho, txo qis inertia, thiab txhim kho kev teb dynamic.

 

Kev Ua Haujlwm Tsis Muaj Suab Nrov: Cov yas muaj cov qauv elastic qis, nqus tau cov kev co kom ua haujlwm ntsiag to.

 

Cov Khoom Uas Ua Rau Nws Tus Kheej Lubricating: Feem ntau cov yas engineering yog lubricated sab hauv, txo qhov kev vam khom rau kev lubrication sab nraud thiab ntev lub sijhawm txij nkawm.

 

Kev Tiv Thaiv Kev Xeb: Tiv taus dej, roj, thiab ntau yam tshuaj lom neeg, lawv tsim nyog siv rau hauv qhov chaw noo noo lossis corrosive.

 

Cov Lus Qhia Txog Kev Xaiv thiab Cov Qauv

 

Raws li tus qauv JB/T 7048, kev xaiv cov yas tawb yuav tsum tau xav txog qhov hnyav, qhov ceev, qhov kub, thiab cov yam ntxwv ib puag ncig. POM yog qhov zoo dua rau kev siv ceev ceev, suab nrov tsawg; PA yog qhov kev xaiv rau cov xwm txheej ua haujlwm nruab nrab; thiab PI raug pom zoo rau qhov kub thiab txias heev lossis qhov yuav tsum tau muaj kev ntseeg siab siab.

 

Cov tawb yas engineering tsis yog tsuas yog hloov hlau xwb; es, lawv tau raug kho kom zoo rau kev ua tau zoo hauv cov ntawv thov tshwj xeeb. Los ntawm kev xaiv cov khoom siv science, kev ua haujlwm zoo, kev ntsiag to, thiab lub neej tuaj yeem txhim kho tau zoo thaum tswj kev ntseeg siab ntawm cov kabmob. Nrog kev nce qib hauv cov thev naus laus zis khoom siv, cov ciam teb ntawm cov yas ua tau zoo hauv cov kabmob yuav txuas ntxiv nthuav dav.
