Abstract

This paper compares the turning and stationary groove configurations of oil lubricated journal bearings for spindle motors of data storage equipment under transient contact conditions such as start-up and shut-down. Shortening the startup time reduces in a linear manner the wear of the herringbone groove and multi-taper bearings in both turning and stationary groove configurations. Lastly, stronger braking control is necessary for the turning groove configuration.
