PCT No. PCT/DK85/00011 Sec. 371 Date Oct. 29, 1985 Sec. 102(e) Date Oct. 29, 1985 PCT Filed Feb. 22, 1985 PCT Pub. No. WO85/03985 PCT Pub. Date Sep. 12, 1985.An eccentric ring and eccentric where the eccentric ring has polygon-shaped cross section with plane side faces whereon a piston rod for a cylinder is abutting is designed with channels (9) for lubricant said channels (9) extending from the plane side faces (2) of the eccentric ring (1) into the middle of the bearing surface (6) of the eccentric ring. In the bearing surface (6) there is provided a system of helical grooves (7) that have such direction, pitch and depth that under the influence of its adhesive power to the rotating bearing journal (8) lubricant is accelerated to describe a movement from the edges of the bearing in a direction towards its center line thus creating a hydraulic pressure whereby the lubricant is pressed through the channels (5) to the plane polygon faces. |
