Txhawm rau txhim kho nws cov khoom lag luam tsis tu ncua, Schaeffler tau tsim thiab kho nws cov B719 thiab B70 series spindle bearings raws li nws cov spindle bearings uas twb muaj lawm. Ntxiv nrog rau kev txo qis kev sib cuag lub kaum sab xis thiab txhim kho pob zoo, cov kab no ntawm cov kabmob no tseem muaj cov ntsaws ruaj ruaj, uas ua rau muaj kev ua haujlwm siab, kev kub ceev, thiab muaj zog thauj khoom.
B series spindle bearings yog thawj zaug uas yuav tsum tau nruab nrog lub siab -ceev tawb, uas yog sib dua (15-20% sib dua), nruj dua, muaj zog tensile zog (5-10%), thiab muaj zog dabtsi yog khoov (20%). Hom tawb no tau raug pov thawj hauv kev xyaum hauv RS (Rugged & Fast) series spindle bearings, qhia txog kev txhim kho tseem ceeb hauv kev nrawm thiab nrawm piv rau cov kabmob uas twb muaj lawm.
Lub tawb tshiab tsim thiab txhim kho cov kabmob qhov chaw kuj tseem txo qis kev ua haujlwm kub thiab kev sib txhuam torque. Kev sib txhuam yog txo los ntawm kwv yees li 15% tshaj qhov siab dua qhov ntau. Ntxiv nrog rau kev txhim kho kev sib txhuam kev ua haujlwm, lub tawb tsim raws li cov qauv tshiab yog ntsiag to thiab tsis tshua muaj lub tawb vibration.
Schaeffler kuj hloov kho qhov kev sib khi tsim ntawm nws cov kabmob kaw los ntawm kev txhim kho lub roundness ntawm lub nplhaib sab nraud. Txoj kab uas hla deviations thiab roundness yuam kev yog compensated los ntawm radial clearance nyob rau hauv cov cheeb tsam. Tsis tas li ntawd, tag nrho cov ntsaws ruaj ruaj nyob rau hauv FAG spindle bearings yog dawb ntawm DEHP plasticizer, ib qho kev phom sij txwv tsis pub los ntawm European REACH cov cai tswj hwm tshuaj txij li xyoo 2015.
Kev ua haujlwm tas li hauv ntau- kab ntawv thov txo qis kev sib cuag lub kaum sab xis los ntawm 35-50% raws li kev tsim, txhim kho qhov tawv nqaij, kinematics, thiab preload uniformity. Cov khoom sib xws tsim tawm ntawm cov kabmob, tshwj xeeb tshaj yog nyob rau hauv ntau kab kev npaj, muab cov neeg siv khoom nrog kev ua haujlwm tsis tu ncua. Txo cov pob tolerances kuj ua kom txo qis suab nrov.
