Sažetak
High demands are placed on gears made from sintered steel regarding wear, scuffing, pitting load capacity, and efficiency. The structure of sintered steel can be influenced by sinter-hardening treatment in such a way that wear load capacity and meshing efficiency can have high values. The paper presents the research into overall efficiency, meshing efficiency, and the tooth friction coefficient of crossed helical gears with wheels made of Fe1.5Cr0.2Mo by applying the sinter-hardening treatment. A calculation method is also given for the determination of the tooth friction coefficient and meshing efficiency of crossed helical gears with wheels made of sintered steel. The results provide the first important information to product developers as indicators for the development of crossed helical gears.
