Cov bearings yog cov "pob qij txha" ntawm cov tshuab.

 

Cov kabmobyog cov "pob qij txha" ntawm cov tshuab, siv los txhawb cov ncej tig.

 

Lawv muab faib ua ob pawg tseem ceeb: dov bearings thiab sliding bearings.

 

Cov kabmob feem ntaumuaj plaub ntu: lub nplhaib sab nraud, lub nplhaib sab hauv, cov khoom dov, thiab lub tawb.

 

Cov khoom siv dov, xws li cov pob me me lossis cov menyuam dov, dov ntawm cov nplhaib sab hauv thiab sab nraud, txo qhov kev sib txhuam hauv lub tshuab. Qhov no ua rau lub tshuab khiav tau zoo dua.

 

Kev nkag siab tob dua txog cov khoom sib xyaw thiab kev faib tawm ntawm cov bearings tuaj yeem pab peb tswj peb cov tshuab zoo dua:

 

1. Plaub yam tseem ceeb ntawm cov kabmob:

Lub nplhaib sab hauv: Haum rau ntawm lub qag tig ntawm lub tshuab thiab tig ua ke.

 

Lub nplhaib sab nraud: Tau teeb tsa rau hauv lub tsev bearing, muab kev txhawb nqa.

 

Cov khoom siv dov: Dov ntawm cov nplhaib sab hauv thiab sab nraud. Lawv muaj cov duab xws li lub voos xwmfab (pob) thiab cov menyuam (cylindrical lossis conical).

 

Tawb: Cais cov khoom dov, tiv thaiv lawv kom tsis txhob sib txhuam thiab sib tsoo.

 

2. Kev faib tawm los ntawm kev thauj khoom:

Cov kabmob radial: Feem ntau yog cov zog uas dais perpendicular rau lub ncej. Piv txwv li, cov kabmob pob sib sib zog nqus.

Cov kabmob thawb: Feem ntau dais cov zog sib luag rau ntawm tus ncej (lub zog axial). Cov kabmob thawb: Muaj peev xwm tiv taus ob qho tib si lub zog ntsug thiab sib luag tib lub sijhawm.

 

3. Cov kabmob zawv zawg piv rau cov kabmob dov: Cov kabmob dov: Kev sib cuag ntawm cov khoom dov, kev sib txhuam tsawg, kev txuag hluav taws xob, yooj yim rau kev teeb tsa tus qauv thiab kev yuav khoom. Lub neej ntev tuaj yeem kwv yees siv cov qauv (piv txwv li, xam L₁₀ lub neej). Cov kabmob zawv zawg: Kev sib cuag ntawm qhov chaw nrog cov roj nplaum nyob nruab nrab. Muaj peev xwm thauj khoom ntau, lub neej ntev, feem ntau siv rau hauv cov tshuab hnyav.

 

Peb yam tseem ceeb rau kev zoo ntawm cov kabmob:

 

Kev xaiv cov khoom siv: Cov hlau bearing zoo muaj qhov nyuaj thiab hnav tsis kam, ua rau lub neej ua haujlwm ntev.

 

Kev ua haujlwm raug: Qhov tiav ntawm qhov chaw ntawm cov nplhaib sab hauv thiab sab nraud thiab cov khoom dov ncaj qha cuam tshuam rau kev ua haujlwm du.

 

Kev ua haujlwm ntawm lubrication: Cov roj nplua nyeem tsim nyog txo qhov kev sib txhuam, txo qhov kub thiab txias ua haujlwm, thiab txhim kho kev ua haujlwm zoo.

 

Cov kev cai tseem ceeb rau kev siv tshuabcov kabmob:

Cov kev cai lij choj yog lub hauv paus rau kev tsim thiab tsim cov kabmob. Lawv feem ntau suav nrog kev kam rau siab ntawm qhov ntev, kev sib hloov raug, kev tshem tawm, kev co, thiab suab nrov. Cov kev ntsuas no yuav tsum tau txiav txim siab raws li qhov xwm txheej ntawm daim ntawv thov tshwj xeeb. Piv txwv li, cov cuab yeej precision xav tau kev sib hloov raug siab, thaum cov tshuab hnyav tsom mus rau qhov muaj peev xwm thauj khoom ntau dua.
