Abstract:
A sintered gearwheel is described having teeth (1) which, in the flank and root region (2, 3), comprise a compacted surface layer (7, 8, 9) which is continuous in the transition portion (4) between the flank and root region (2, 3) and has a residual porosity of less than 10%. In order to increase the load-bearing capacity it is proposed that the compacted surface layer (9) is formed with a lower thickness in the transitional portion (4) between the flank and root region (2, 3) than in the adjacent flank and root regions (2, 3).
