Txij li cov yam ntxwv ntawm cov bearings siv zoo heev cuam tshuam rau kev ua tau zoo ntawm gyroscope, nws yuav tsum tau xaiv cov khoom ua tau zoo tshaj plaws ntawm NSK ultra-precision me me bearings.Ob lub bearings txhawb lub siab ceev rotor ncej thiab nws cov ncej sab nrauv (gimbal) yuav tsum muaj lub sijhawm tsis muaj kev sib txhuam.Cov hom tseem ceeb thiab siv tau ntawm cov kabmob tshwj xeeb rau gyroscopes tau qhia nyob rau hauv Table 11. Lub rotor thiab gimbal txhawb nqa bearings feem ntau yog ua los ntawm cov ntiv tes super-precision bearings, thiab lawv qhov loj me thiab NSK tus neeg sawv cev qauv yog qhia hauv Table 12 (nplooj B75. ).Tsis tas li ntawd, muaj ntau yam tshwj xeeb bearings rau gyroscopes nrog cov duab tshwj xeeb.(2) Cov yam ntxwv ntawm gyroscope bearing Tshwj xeeb bearing rau rotor Tshwj xeeb bearing rau gimbal Fig. 4 Ib qho piv txwv ntawm kawg npog pob bearing Fig. 3 Roj kom muaj nuj nqis thiab torque Roj 1 poob r/min concentration 1% 1 poob concentration 0.5% 1 poob concentration 0.2 % 1 Tshwj xeeb bearings rau drip rotors yuav tsum tsis tshua muaj zog torque thiab lub sij hawm ntev stability thaum lub sij hawm high-ceev kev sib hloov.Yog li ntawd, cov roj puv tawb feem ntau siv.Kuj tseem muaj txoj hauv kev lubricating uas siv cov kuab tshuaj yaj-solved lubricating roj los txhaj cov kabmob, tab sis vim tias qhov kev sib txhuam torque cuam tshuam los ntawm cov roj, yuav tsum tau kho kom haum (saib daim duab 3).Tus nqi ntawm cov roj tuaj yeem hloov kho los ntawm kev sib cais centrifugal kom tau txais lub zog ruaj khov.Raws li rau hom kabmob, kuj tseem muaj cov kabmob tshwj xeeb uas qhov kawg npog thiab lub nplhaib sab nraud tau sib xyaw ua ke (saib daim duab 4).

Qhov tshwj xeeb bearing rau gimbal ua raws li cov zis ncej, uas yuav tsum muaj kev sib txhuam torque tsawg thiab kev co kuj.Table 13 teev qhov siab tshaj plaws pib torque ntawm tus neeg sawv cev bearings, thiab qis dua pib torque tuaj yeem tau los ntawm kev ua tiav txoj kev sib tw thiab tsim tshwj xeeb hauv lub tawb.Tsis tas li ntawd, txhawm rau tiv thaiv fretting hnav tshwm sim los ntawm kev co sab nraud, kev kho deg txheej hardening yog nqa tawm ntawm txoj kev sib tw los txhim kho kev tiv thaiv kev vibration.
