Abstract
The lubricant line structure for the radially inner surface of the bearing in accordance with the present invention mainly comprises a plurality of zigzag lubricant lines. The zigzag lubricant lines are symmetrically extended along an axis of the bearing and connected two end surfaces. When a shaft in the bearing is rotated in clockwise or counterclockwise, outer lubricant is sucked into an interior of the bearing so as to form plurality of convergent lubricant points.
Claims7
A lubricant line structure for a radially inner surface of a bearing comprising:
- a plurality of zigzag lubricant lines axially extended on a radially inner surface;
- and
- a plurality of turning points distributed at opposites sides of a centerline of the zigzag lubricant line to form a plurality of convergent lubricant points, the convergent lubricant points comprising a plurality of reverse-convergent lubricant points and a plurality of obverse-convergent lubricant points;
- wherein the reverse-convergent lubricant points are formed when a shaft is rotated in counterclockwise, and the obverse-convergent lubricant points are formed when the shaft is rotated in clockwise.
