SINTERED PLAIN BEARING WITH CONTINUAL VARIATION OF THE BORE DENSIFICATION

摘要

The invention relates to a porous plain bearing (5) for engines and gearboxe s, comprising a circular borehole (14) provided with highly compressed, at leas t approximately closed-pore regions (9) and low-compressed, open-pore regions (10) which are alternately distributed over the circumference, the borehole diameter of the highly compressed and low-compressed regions (9, 10) being a t least approximately identical. The invention also relates to a method and a device for the production of said porous plain bearing.
