Title:
SPHERICAL PLAIN BEARING WITH CONTOURED LUBRICATION GROOVES
Document Type and Number:
WIPO Patent Application WO2008011171
Kind Code:
A9
Abstract:
A spherical plain bearing has outer and inner rings each having a bearing surface, one bearing surface being in sliding disposition to the other. The inner ring has a third bearing surface for engaging a member to be mounted to the bearing. There is a lubrication groove in one or more of the first, second or third bearing surfaces, the lubrication groove comprising a contoured side. In an alternative a spherical plain bearing, there is a segmented lubrication groove in the third bearing surface that might have a sharp edge or a contoured side. A contoured lubrication groove can be formed by forming a lubrication groove that has a sharp edge; and machining the sharp edge to a contoured side having a reduced tendency to wipe lubricant from a second surface facing the lubrication groove.
