Experimental stress analysis of a hollow bearing ball with web reinforcement

Includes bibliographical references (page 20)Problems encountered with bearings operating in very high DN values (bearing bore in millimeters times shaft speed in rpm) have led to experiments on several types of hollowed ball bearings which improve bearing fatigue life due to mass reduction and lower centrifugal forces. This study is an experimental stress analysis of a ball bearing with approximately 50% mass reduction made, by drilling a concentric hole into the ball bearing leaving a web at the center. The web is presumed to improve flexural fatigue life over a no web configuratio
