THRUST SLIDE BEARING
Document Type and Number:
Japanese Patent JP2020020359
Kind Code:
A
Abstract:
To provide a thrust slide bearing capable of preventing friction increase or seizure caused by lubrication lack by promoting a thickener derived deposition film formation and improving re-flowability of a base oil into a sliding portion.SOLUTION: The present invention relates to a thrust slide bearing comprising a first member and a second member which are relatively slid under urea grease intervention. A recessed groove is formed at least at any one of a first member side or a second member side. Inside of the recessed groove, a grating-like uneven periodic structure is provided in a region which extends from a sliding region to a circumference of the sliding region and is made intermittent in a radial direction or a circumferential direction. A projection in the grating-like uneven periodic structure is made lower than a non-processed part in the periodic structure.SELECTED DRAWING: Figure 1
