摘要： 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.

摘要： A sintered friction bearing for motors and gears with a bearing surface, which is formed by a bearing bore and can have a lubricant from lubricant depositories in the bearing. The bearing bore has alternating highly compressed, small-pored bearing surfaces distributed over the circumference and slightly compressed, open-pored lubricant depositories from one front face to the other front face of the bearing. Lubrication of the sintered friction bearing is improved because the lubricant depositories are embodied as grooved structures with at least two longitudinal grooves, which are inclined at an acute angle with respect to a center axis of the bearing bore from one front face to another front face of the bearing.

摘要： A method for producing a milling disc with embedded insets of hard metal, ceramics or other similar hard materials. The milling disc has a centrical bore in the base body of the disc. The tips of the insets protrude over the circumference of the disc body. The invention also relates to a milling disc produced according to the method wherein a powdery sintered metal material is filled into the recess of a mold pertaining to a compression molding die, and the mold matches the outer contour of the disc base body. Pre-fabricated insets are inserted into the sintered metal material and are positioned in the mold of the compression molding die. A green compact is subsequently pressed in the compression molding die and then taken out of the compression molding die. The green compact is sintered with the pressed insets and is subjected to hardening and/or surface treatment, if required. According to the milling disc, the resistance of the insets in the disc base body and the properties of the disc base body are improved.
