Abstract

A split-outer-ring three-point contact ball bearing (SO-TCBB) features a removed portion in the circular outer-ring to allow three-point contact. This study introduces a quasi-static model to analyze contact characteristics and predict the occurrence of a phenomenon called truncation of contact area (TCA) in SO-TCBBs. TCA implies that portions of the contact areas between balls and outer-race partially separate, exacerbating premature wear and reduced bearing life. Under pure axial loads, an increase in the axial load leads to earlier occurrence of TCA in the inner ring. Combined loads cause varying contact points and TCA for each ball, with higher radial loads accelerating TCA. Increasing radial load results in an earlier occurrence of TCA. Appropriately increasing the amount of removed portion of the outer ring produces a three-point contact at lower speeds, effectively reinforcing resistance against centrifugal forces at both contact points on the outer ring and impeding the TCA in both inner and outer rings.
