FIELD: systems for rotation plastic working of materials, namely manufacture of gear wheels with internal gearing from sintered bimetallic powder materials.
SUBSTANCE: method comprises steps of knurling toothed profile on sintered bimetallic annular blank made by simultaneously forming working layer and base and sintering blank. Said blank includes base and internal working layer with thickness t = (4.0 - 8.0 )m. Toothed profile is knurled by means of teeth knurling rollers after sintering blank at preliminarily compacting working layer by value h of technological allowance in teeth apexes h = (0.25 -1.25)m where m - gearing modulus.
EFFECT: enhanced efficiency of method, rational consumption of deficient materials.
