How the Coefficient of Friction Impacts Capacity of Hub-Shaft Joints for Special Purpose Turbomachinery (Feb 2023)

Friction coefficient at the hub-shaft interface is critical to joint torque capacity. In a test program designed for a high-profile customer within the industry, several common but important hub-shaft joint configurations were tested to determine how friction can affect the torque capacity of these configurations. This paper outlines the performance results obtained within the test program.
