Lubqhov zoo thiab qhov tsis zoo ntawm lub zog cua lub ntsiab bearing

 

TCov hom tseem ceeb ntawm cov kabmob spindle siv rau megawatt cua turbines yog 3-point bearing bearing tsim thiab 2-point bearing bearing tsim,Thov kos rau hauv qab noaqhov zoo thiab qhov tsis zoo ntawm these bearingqauv

 

Cov menyuam kheej kheej bearings + cov menyuam kheej kheej bearings

Qhov zoo yog tias tsis muaj lossis tsawg dua qhov kev thauj khoom ua rau lub gearbox, thaum cia siab rau lub caj npab torsion kom tiv taus qhov deformation tsawg dua, thiab kev sib dhos yooj yim heev.

 

Cov kev tsis zoo yog raws li nram no:

1) Qhov axial clearance yog qhov loj heev, thiab qhov chaw ntawm lub hub hauv qhov kev taw qhia axial tsis zoo;

2) Tsis muaj preload ntawm lub bearing tseem ceeb, thiab qhov axial displacement yog qhov loj heev tom qab loading, thiab tib lub sijhawm, vim tsis muaj preload, ib lub roller yuav tsis tig, uas ua rau swb, uas yuav tsim lub load loj heev thiab cuam tshuam rau lub neej ntawm lub bearing;

3) Qhov loj ntawm tus ncej yog me me, thiab qhov cuam tshuam ntawm qhov thauj khoom ntawm tus ncej yog loj.

 

Cov kabmob kheej kheej + cylindrical roller bearings

Qhov zoo ntawm qhov kev tsim kho no yog tias tsis muaj lossis tsawg dua qhov kev thauj khoom ua rau ntawm lub gearbox, thaum cia siab rau lub caj npab torsion kom tiv taus qhov deformation tsawg dua, thiab kev sib dhos yooj yim heev.

 

Lubcov kev tsis zoo yog raws li nram no:

1) Qhov axial clearance yog qhov loj heev, thiab qhov chaw ntawm lub hub hauv qhov kev taw qhia axial tsis zoo;

2) Tsis muaj preload ntawm lub bearing tseem ceeb, thiab qhov axial displacement yog qhov loj heev tom qab loading, thiab tib lub sijhawm, vim tsis muaj preload, ib lub roller yuav tsis tig, uas ua rau swb, uas yuav tsim lub load loj heev thiab cuam tshuam rau lub neej ntawm lub bearing;

3) Qhov loj ntawm lub thav duab tseem ceeb yog loj lossis muaj ntau qhov, ua rau tus nqi ntawm lub thav duab tseem ceeb siab dua thiab kev ua tiav nyuaj dua;

4) Vim tias cov cylindrical roller bearings yog rhiab heev rau coaxiality thiab kev sib piv ntawm cov nplhaib sab hauv thiab sab nraud, lawv tsis zoo hauv kev tsim lossis sib dhos

Hauv qhov no, qhov radial clearance ntawm spherical roller bearings yuav ua rau puas tsuaj rau cylindrical rollers;

5) Vim yog qhov me me ntawm tus ncej thiab tus kabmob, qhov kev tawv ntawm lub cev ncej yog qhov tsawg heev, thiab qhov thauj khoom muaj kev cuam tshuam ntau dua rau tus ncej.

 

Ob kab tapered roller bearings + cylindrical roller bearings

Qhov zoo tshaj plaws ntawm cov qauv kev coj tus kheej no yog:

1) Tsis muaj qhov axial clearance, thiab qhov axial positioning zoo dua;

2) Lub peev xwm ntawm cov kabmob tuaj yeem nce ntxiv los ntawm kev nce qhov deb ntawm cov kabmob, thiab qhov ntau ntawm cov kabmob siv tau loj dua;

3) Lub cheeb ntawm lub ncej thiab cov kabmob me dua, thiab tus nqi qis dua;

4) Vim yog qhov tshem tawm ntawm axial clearance, qhov kev nruj ntawm lub cev ncej yog qhov siab heev, thiab qhov dynamic load muaj me ntsis cuam tshuam rau nws.
