Simulation of the power skiving process for cutting an internal gear with modelling of undeformed chips

Aim. The aim of this paper is to create a 3D model of the undeformed chips produced during the cutting of an internal gear ring. By modelling the power skiving process, it is necessary to investigate the influence of various geometric and technological parameters on the thickness and cut area of the chips produced. Method. By simulating the gear turning process, it is possible to reproduce the cutting of the gear teeth and accurately determine the geometric parameters and the shape of the undeformed chip at each moment.

Gears with Asymmetric Tooth Profiles and New Alternative Method of Their Manufacturing

The article presents a new gears cutting process – radial circular generating method and describes its multiple benefits for manufacturers of transmissions. The overall increase of efficiency is realized due to using a simple tool and the conventional gear tool machine for cutting gears of different types. In particular, this new method was used for cutting gears with the asymmetric profiles of wheel teeth, which allows considerably amplifying power transmission density, increasing load capacity, and reducing size and weight.
