GWJ Technology integrated as the world's first manufacturer of professional calculation software for gear transmission high-purity steels from Ovako from Sweden. In close cooperation, the two high-purity steels 159X and 159Q were implemented in the gear modules for spur gears. They are based on case hardening steel 18CrNiMo7-6.

Due to significantly lower impurities, these steels have modified Wöhler curves. This makes them comparable to the 18CrNiMo7-6 in the static area. In the fatigue range, however, 159Q offers approximately 30% higher flanking capacity and 60% higher tooth base strength. These higher fatigue strength values ​​are based on Ovako internal investigations and have been verified by investigations at the WZL in Aachen and at the FZG in Munich.

The steel 159X has a slightly smaller increase in performance compared to 18CrNiMo7-6 and is therefore well suited, among other things, when improvements to existing designs are necessary. The potential of the 159Q can be used particularly in new designs. It can be advantageous to focus on optimized feeding capacity. This generally results in better gearing efficiencies and thus lower power losses. From GWJ Technology's perspective, these Ovako steels open up completely new possibilities for transmissions and have high potential for further increasing performance Geargears and gear components.

Efficient gear wheel perspectives made of high-performance plastic

The two steels 159X and 159Q are available in all three GWJ software solutions for gear calculation, ie in the web solution "Eassistant", in the desktop application TBK and in the special software "Gear Engineer" for 5 gear cutting.
