The invention relates to a spur gear wheel with a gear body () made from a sintered material, which has a circumference around which teeth () are distributed projecting in the radial direction, and which is delimited by two end faces () in the axial direction. At least one shaped element () in the form of a recess () and/or an elevation () and/or a compacted area is provided on at least one end face () in the region of the teeth () and/or in the radial direction underneath the teeth ().

Gear wheel

The invention relates to a rolling tool () for producing crowned teeth on a gear () using a transverse rolling process, in particular for compressing the teeth of the gear () at least in some areas, comprising a tool body () which has tool teeth () projecting radially outward for meshing with the teeth of the gear () to be rolled, wherein at least some areas of the tool teeth () are concave in the axial direction in the area of the tooth flanks.

Rolling tool, apparatus and method for the production of crowned teeth, and gear

The invention relates to a tool for compacting the surface of a component () produced by powder metallurgy, comprising a mold () and a stamp (), wherein in the mold () a recess () is provided which extends from a first mold opening () to a second mold opening (), and which has a wall surface () for supporting the component (), and the stamp () has a stamp length () and a stamp surface (), wherein the inner diameter () of the recess () of the mold () becomes smaller from the first mold opening () in the direction of the second mold opening () or an external diameter () of the stamp () becomes greater over the stamp length (), and wherein a compaction element () is arranged on the wall surface () of the mold () or on the stamp surface (). The compaction element () is configured to have a thread-like progression.
