2:30 PM TESTING, THERMAL ANALYSIS AND FRICTION OPTIMIZATION OF ANGULAR CONTACT BALL BEARING FOR EV APPLICATION

NTN-SNR tested different bearing design on high speed test
bench, with friction and temperature measurements. A simple
thermal model enabled to explain heat flow through rings, oil,
housing. This study ended in bearing design and lubrication
optimization.
• New friction challenges with high-speed
• Strategies to reduce the losses: materials vs. mechanics
• Preserving the lifetime of bearings
