flywheel spindle

This paper analyses heating cause of double centripetal spherical rolling bearing in main drive fly wheel bearing seat of 500mm rolling mill and it finds out when double centripetal spherical rolling bearing is arranged in paired in a bearing seat the adjusting function of the bearing is decreased.

对５００ｍｍ轧机机列主传动飞轮轴承座双列向心球面滚子轴承发热原因进行分析，发现双列向心球面滚子轴承在同一轴承座内成对布置时，削弱了其调心功能。
