A 4-DOF dynamic model for ball bearing with multiple defects on raceways

Abstract: Localized defects in ball bearing components would cause additional vibration and it is imperative to reveal the vibration mechanism. The relationship between fault characteristic frequency (fBPFI and fBPFO) and multiple defect parameters of ball bearing were given in this paper. Considering elastohydrodynamic lubrication (EHL), radial clearance, time-varying displacement and excitation force generated from multiple defects, a 4 degree-of-freedom (DOF) dynamic model for ball bearing with multiple defects on in… Show more

“…Considering the displacement increment caused by local fault, roller deflection, and radial load, Patel and Upadhyay 33,34 built a vibration model of cylindrical roller bearing and solved vibration equations by using Newmark-b method, and investigated the vibration response of REB with single fault and compound fault at different speeds. Gao et al 35 presented a vibration model of REB with multiple faults on races and analysed dynamic behaviour for the different numbers, positions and angles of fault.…”

“…Li et al 15 developed a nonlinear model for REBs with multi-point defects on the outer raceway and investigated the effect of the number, location and size of the defects on the dynamic characteristics of bearings. Gao et al 16 created a 4 DOFs dynamic model for REB and investigated the vibration characteristics of bearings under the impact of multi-point defects on the raceways. Using a three-dimensional analysis method, Gupta 17 representatively suggested an extensive dynamic model for REB in order to characterize the motion and force states of its components.…”

“…Turnbull et al 21 integrated the elastodynamics with outer raceway for ball bearing into a dynamic model to analyse the power loss of bearing and lubricating performance of contact zone. Gao et al 22 considered the influence of lubricating oil film and presented a dynamic model with multiple surface defects for ball bearing to study the included angle and number of defects on vibration response. Considering the influence of lubricating oil, Wen et al 23 built a complete 14-DOF model of defective ball bearing to analyse the collision between ball and cage in defect area.…”
