Title: SINTERED PLAIN BEARING, AND METHOD AND DEVICE FOR PRODUCING A SINTERED PLAIN BEARING
Abstract:
The invention relates to a sintered plain bearing (10; 10a) for motors and transmissions, comprising a circular bearing bore (11), wherein the bearing bore (11) has at least two regions (15a to 15f) compressed to different degrees, wherein a highly compressed region (15a to 15f) is approximately closed-pored and a region (15a to 15f) that is compressed slightly in comparison with the highly compressed region (15a to 15f) is open-pored in order to absorb and discharge lubricant, and wherein the bearing bore diameter (d) is at least approximately identical in the closed-pored and open-pored regions (15a to 15f). According to the invention, the at least two regions (15a to 15f) compressed to different degrees extend radially circumferential in the circumferential direction of the bearing bore (11), the degree of compression of a region (15a to 15f) is at least approximately constant in the circumferential direction of the bearing bore (11), and the degree of compression varies in the direction of a longitudinal axis (12) of the bearing bore (11).
