Plain bearing shell for use in hydrodynamic sliding bearing for supporting counter-rotor, has grooves recycling lubricant to axial center of shell and aligned in axial boundary region toward center of shell

摘要

The shell (10) has an inner-extensive sliding surface and grooves (22) extending on an inner side of the shell. The grooves for recycling a lubricant i.e. oil, to an axial center of the shell along direction of rotation (A) of a counter-rotor are aligned in an axial boundary region toward the center of the shell. An oil groove (12) runs along peripheral direction for distributing the lubricant on the sliding surface. The grooves extend between the oil groove and an axial front surface (16) and exhibit a setting angle (gamma) along circumferential direction.
