Abstract

This paper deals with structural strength and machinability of large scale nitrided internal spur gears when using steels not containing aluminum. It has been shown that strength and service properties of gears made from such steel grades are higher than from serial aluminum steels for their principal characteristic: core hardness, higher case depth, better machinability and accuracy and absence of brittle components in nitrided case.

Keywords toothed wheels, nitriding, thickness of a hardened layer, alloy steel, aluminum, processability, machinability, milling, chiselling
