Abstract

Crossed helical gears are used in cars and in many household appliances. The trend towards increased comfort in motor vehicles has led to the utilisation of more than a hundred servo-drives in luxury class automobiles. Important advantages of crossed helical gears are their easy and inexpensive design, low noise performance and high gear ratio that can be realised in one step. Sintered steel is a material with very favourable properties for the manufacture of crossed helical gears. High demands are set on gears made from sintered steel regarding wear and pitting load capacity. This report shows the results of the investigation into pitting resistance of crossed helical gears made of iron-based sintered material Fe1.5Cr0.2Mo that has undergone additional treatment.
