Beschreibung
Zusammenfassung:	The invention relates to a porous plain bearing (5) for engines and gearboxes, comprising a circular borehole (14) provided with highly compressed, at least 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 at least approximately identical. The invention also relates to a method and a device for the production of said porous plain bearing. L'invention concerne un palier lisse fritté (5) destiné à des moteurs et transmissions et comprenant un alésage de palier (14) rond. L'alésage de palier (14) présente alternativement des zones (9) au moins approximativement à pores fermés et fortement comprimées et des zones (10) à pores ouverts et faiblement comprimées. L'alésage de palier des zones fortement et faiblement comprimées (9, 10) ont des diamètres au moins approximativement identiques. L'invention concerne également un procédé et un dispositif de production de ce palier lisse.
