IPC: F16F15/26
Filed: 2002-08-30
Abstract: <P>PROBLEM TO BE SOLVED: To properly lubricate between a journal and a bearing at a prescribed position where pressure becomes the highest when the center of gravity of a balance shaft is at the lowest position.  <P>SOLUTION: In a state that the center of gravity G of the rotating balance shaft 1 is at the lowest position, the pressure between the journal 6b and the bearing 2b is the highest at the position P1. In this state, an opening 10a of a lubricating passage 10 is formed to position to the front side more than the position P1 in a rotation direction. Thus during the rotation of the balance shaft 1, the opening 10a reaches the position P1 before the center of gravity G of the shaft 1 reaches the lowest position, and lubricating oil is discharged from the opening 10a. Accordingly when the center of gravity G is at the lowest position and the pressure between the journal 6b and the bearing 2b is highest at the position P1, oil film required between them can be formed of the lubricating oil.  <P>COPYRIGHT: (C)2004,JPO
