“…Important advantages of the crossed helical gears are their easy and inexpensive design, good noise performance and high ratio that can be realized in one step (Figure 2). Crossed helical gear in drives for seat adjustment [1] In these applications are used often combinations with pinions or worms made of steel, and gear wheels made of plastic. The gear wheels are made by injection molding at low cost in large quantities.…”

Crossed helical gears are used in cars and many household appliances. The trend towards increased comfort in motor vehicles has led to the utilization of more than a hundred servo-drives in luxury class automobiles. Key advantages of crossed helical gears are their simple and inexpensive design, good noise performance and high ratios that can be realized in one step. Sintered steel is a highly favorable material for wheels in crossed helical gears. They are able to satisfy high performance demands in the areas of wear, fretting, tooth fracture and pitting load capacity. This report describes the results of an examination into the use of the iron-based sintered material Fe1.5Cr0.2Mo with pyrohydrolysis in crossed helical gears, in the areas of wear resistance and other damage types under different speeds and loading conditions.
