Abstract

PURPOSE: To lengthen the lifetime of a pivot bearing under heavy load, by making the conical angle of the center hole of the pivot bearing and the radius of curvature of the spherical surface of the bottom of the center hole equal to or less than those of the tip of a spindle and providing a lubricating oil inlet port at the bottom of the center hole.
CONSTITUTION: The conical angle θ2 of the center hole of a pivot bearing 13 and the radius r2 of curvature of the center hole are made equal to or slightly less than those θ1, r1 of a spindle 11. A lubricating oil inlet port 15 is opened toward the shoulder part of the center hole of the pivot bearing 13 or toward the conical surface of the spindle 11. According to this constitution, vibration- absorbing oil in a bolster not shown in the drawing is let to easily flow in toward the contact surface of the bearing 13 and a good lubricating oil film 10 is made. This results in lengthening the lifetime of the bearing 13 under heavy load.
