30202 Tapered roller bearings, ib kab

Kev Piav Qhia Luv:

Cov kabmob tapered roller ib kab yog tsim los kom haum rau cov khoom sib xyaw ua ke, ua haujlwm radial thiab axial loads tib lub sijhawm. Cov kab projection ntawm cov raceways ntsib ntawm ib qho chaw sib xws ntawm lub axis bearing los muab qhov kev ua haujlwm dov tiag tiag thiab yog li ntawd qis frictional moments thaum lub sijhawm ua haujlwm. Lub peev xwm nqa axial load ntawm cov kabmob tapered roller nce nrog kev nce lub kaum sab xis α. Qhov loj ntawm lub kaum sab xis, uas feem ntau yog ntawm 10 ° thiab 30 °.

Cov yam ntxwv ntawm Tapered roller bearings

1. Kev sib txhuam tsawg
Qhov tsim qauv zoo tshaj plaws ntawm lub log thiab qhov ua tiav ntawm qhov flange txhawb nqa kev tsim cov roj nplua nyeem, ua rau muaj kev sib txhuam tsawg dua. Qhov no kuj txo cov cua sov sib txhuam thiab kev hnav flange.

2. Txhim kho kev ntseeg siab ua haujlwm
Qhov chaw tiav zoo tshaj plaws ntawm cov nplaim sib cuag ntawm cov menyuam thiab cov raceways txhawb nqa kev tsim cov zaj duab xis hydrodynamic lubricant.

3. Kev sib xws ntawm cov menyuam cov ntaub ntawv thiab qhov ntau thiab tsawg
Qhov kev kam rau siab ntawm qhov ntev thiab qhov geometric ntawm cov bearings tapered roller yog zoo ib yam. Qhov no muab kev faib khoom zoo tshaj plaws, txo cov suab nrov thiab kev co, thiab ua rau kev teeb tsa preload kom raug dua.

4. Daim ntawv thov kev coj tus kheej
Feem ntau, ib kab tapered roller bearing yuav raug kho kom haum rau lwm kab tapered roller bearing. Los ntawm kev siv preload, yuav ua tau ib daim ntawv thov rigid bearing.

5. Sib cais tau
Lub nplhaib sab hauv nrog lub log thiab lub tawb sib dhos (lub khob hliav qab) tuaj yeem ntsia tau sib cais ntawm lub nplhaib sab nraud (khob).
