Surface integrity aspects in gear manufacturing

摘要

Gears are highly loaded components in many different application areas such as automotive,aircraft turbines,ships or wind energy systems.The demand on gears can be summarized by ever rising load capacity on the one hand side and significant noise reduction on the other hand.Both demands can only be fulfilled by adapted gear finishing processes generating the best possible macro-and micro geometry as well as the desired surface integrity state.The paper presents research work on analyzing the thermal load on gears during gear hobbing,surface integrity states by different hard gear finishing operations and possibilities to avoid thermal damage in gear manufacturing by adapted process monitoring and fast non-destructive analyzing techniques.
