Abstract:
A sintered plain bearing for a motor and a gear drive, comprising:a structure including a bearing bore and a running surface formed by the bearing bore, wherein: the running surface includes high-compaction, small-pore running surfaces, the structure includes axially extending, low-compaction, open-pore lubricant reservoirs for providing a lubricant for application to the running surfaces, the running surfaces and the lubricant reservoirs are alternatingly distributed over a circumference of the bearing bore, each one of the lubricant reservoirs includes a channel structure having a plurality of longitudinal channels and channel crests arranged between adjacent longitudinal channels, and at least some of the longitudinal channels are configured to be in fluid communication with a shaft adapted to be received by the bearing bore, and at least some of the channel crests are configured to be in contact with the shaft, such that corresponding ones of the channel structures transfer the lubricant to the shaft when the shaft is received by the bearing bore.
