Abstract
This paper presents results of numerical analysis of rolling process of internal toothing. Numerical simulations of the rolling process were made basing on finite element method (FEM), using commercial software DEFORM-3D in version 10.0. Geometrical models applied in FEM calculations were discussed in details. Calculations were made in three dimensional state of strain with consideration of thermal phenomena. During research works, geometrical parameters of obtained parts were analyzed, distributions of effective strain, effective stress and temperatures as well as the process force parameters were given. Next, the influence of particular process parameters on tools durability and the possibility of presence of phenomena disturbing the process stability were discussed. Described results of numerical research confirm the possibility of forming of internal toothing by means of rolling methods and constitute the introduction for a more complex analysis of metal forming processes of internal toothing.
Highlights
Toothed wheels, which mainly constitute elements of drive transmission, are widely applied in machines design [1,2,3,4,5]
3 Results and discussion In order to confirm the rightness of assumed metal forming conception, numerous simulations of internal toothing rolling process were made

Summary
Toothed wheels, which mainly constitute elements of drive transmission, are widely applied in machines design [1,2,3,4,5]. Among many methods of toothing manufacturing, rolling processes should be considered, in which the outline of the formed toothing is the envelope of particular profile points of teeth of rotating tools. In order to meet the industrial requirements, numerous methods of toothed wheels metal forming, which are to a large extent connected with rolling techniques [22, 23], have been worked out at Lublin University of Technology.
