Summary: The paper proposed a dynamic model including thermo-elastohydrodynamic lubrication (TEHL) to investigate high-speed angular contact ball bearings. The results showed that the gyroscopic moment of the ball increased with higher load under constant axial load, and that sliding speed and film temperature significantly increased with a sudden decrease in axial load due to friction moment decline.

Summary: This paper proposes a novel contact model and a thermal network model considering the thermal expansion effect, as well as an improved dynamic error model for multilink mechanisms. The correctness of the proposed model is verified by analyzing the influence of parameters on the position error of the bottom dead point. The study demonstrates that the punching force and thermally induced variable stiffness significantly increase the position error of the bottom dead point, reducing the machining precision. Additionally, a compensation algorithm based on the improved dynamic error model with online modification is proposed, effectively reducing the position error of the bottom dead point.

Summary: A unified rolling contact tribology model is proposed for dry-lubricated angular contact ball bearings, considering high combined loads and rolling contact effects. The effects of friction coefficients, rotating speeds, and combined loads on the skidding and spinning characteristics of the bearings are studied. The developed model accurately predicts the bearing kinematical and tribological behavior by considering macro/micro-slipping, creepage, and self-spinning motions of the ball and discarding the raceway control hypothesis.

Summary: This paper presents the dual reciprocity method (DRM) based on compactly supported radial basis functions (CSRBFs) and the line integration boundary element method (LIM-BEM) for accurately predicting the thermal error caused by temperature change in the high-speed spindle-bearing system. The proposed method builds a thermal-deformation coupling model using boundary information and obtains results through line integrals. Experimental validation shows that the proposed model is more suitable for thermal-deformation coupling calculations, with satisfactory universality and accuracy.

Summary: This study investigates the lubrication characteristics and heat generation characteristics of ball bearings for cryogenic turbopumps. The frictional coefficients between different materials and the performance of the bearings under various conditions were analyzed. The results show that the power loss due to ball spinning-sliding and LN2 churning and drag is significant, and the spin-roll ratio of the ball on the inner raceway is a key indicator for this type of bearing.

Summary: This paper investigates the cage whirl state and its stability in cylindrical roller bearings under different operating conditions. The study identifies three types of cage whirl: disordered whirl, local periodic whirl, and regular circular whirl. The collision force between the roller and cage plays a significant role in determining the stability of the cage whirl, while bearing slipping has minimal effect.
