Pob Bearing Internal Clearance Thiab Specified Tus Nqi

Qhov loj ntawm qhov kev tshem tawm sab hauv (tseem hu ua kev tshem tawm) thaum lub sijhawm ua haujlwm ntawm cov kabmob dov muaj kev cuam tshuam zoo rau cov kabmob kev ua haujlwm xws li qaug zog lub neej, kev co, suab nrov, thiab kub nce.
Yog li ntawd, xaiv qhov kev tshem tawm sab hauv ntawm cov kabmob yog qhov kev tshawb fawb tseem ceeb rau cov kabmob uas txiav txim siab qhov loj ntawm cov qauv.
Feem ntau, txhawm rau kom tau txais tus nqi ntsuas ruaj khov, qhov ntsuas qhov ntsuas tau muab rau cov kabmob, thiab tom qab ntawd qhov kev tshem tawm raug kuaj. Yog li ntawd, qhov ntsuas clearance tus nqi yog loj tshaj qhov theoretical clearance (nyob rau hauv radial clearance, kuj hu ua geometric clearance), uas yog, muaj ib tug ntau elastic deformation tshwm sim los ntawm lub xeem load (hu ua qhov kev xeem clearance ntau dua qhia qhov txawv).
Feem ntau, kev tshem tawm ua ntej kev teeb tsa tau teev tseg raws li theoretical internal clearance.
