Abstract
A sintered plain bearing for motors and gear drives, having a running surface formed by a bearing bore and capable of having lubricant applied to it from lubricant reservoirs in the bearing, in which the bearing bore has, alternatingly distributed over the circumference, high-compaction small-pore running surfaces and axially extending low-compaction open-pore lubricant reservoirs. Lubrication is improved, especially in the initial phases of operation, by the fact that the lubricant reservoirs are constituted by channel structures having at least two longitudinal channels, and that at least in some of the channel structures, some of the channel crests remaining between adjacent longitudinal channels are in contact with the shaft received by the bearing bore in order to transfer lubricant.
