<P>PROBLEM TO BE SOLVED: To provide a bearing lubrication mechanism and a multistage rolling mill, capable of surely preventing various kinds of damages (seizure or the like) of a bearing caused due to poor lubrication of the interior of the bearing by monitoring the flow rate of compressed air flowing through a supply passage by a sensor. <P>SOLUTION: A rolling bearing 12 comprises a stationary ring 14 kept in a non-rotating state, a rotating ring 16 rotatably arranged facing the stationary ring, a plurality of rolling elements 18 rollably arranged between the stationary ring and the rotary ring, and a sealing mechanism 21 for sealing the bearing interior partitioned between the stationary ring and the rotary ring, from the outside of the bearing. The bearing lubrication mechanism supplies a lubricant with the compressed air into the interior of the bearing 12 so as to lubricate the bearing. The lubricant is delivered with the compressed air from a lubricant supply source and conveyed by the compressed air through the supply passage leading from the lubricant supply source to the bearing interior. The supply of the lubricant to the rolling bearing is controlled by monitoring the flow rate of the compressed air flowing through the supply passage by the sensor Sa. <P>COPYRIGHT: (C)2009,JPO&INPIT |
