  • End profile on slide bearing complementary elements for reducing surface pressure
    Patent number: 7954999
    Abstract: The invention relates to an end profile on slide bearing complementary elements having a pin (22) and at least one bearing sleeve (24, 24?) for receiving the pin (22), said pin (22) absorbing an eccentric force (F) which acts perpendicularly with respect to the pin/bearing sleeve unit (20), and the at least one bearing sleeve (24, 24?) being of cylindrical configuration and the pin (22) being of tapering configuration in a manner which extends from predefined positions in each case toward the axial end. In addition, a geometrically opposed geometry of the pin and the bearing sleeve is claimed.
    Type: Grant
