Full Contact Analysis vs. Standard Load Capacity Calculation for Cylindrical Gears

摘要

Modern gear design is driven by full tooth contact analysis (TCA) to determine adequate gear microgeometry. Engineers strive to optimize load distribution and make use of the full load carrying capacity of the gearset. Local stress levels in the tooth contact and the tooth root are important calculation results, but reliable values for the limits of the load carrying capacity are available for standard methods, e.g. - ISO 6336. Therefore, the relevant power ratio and safety factors are still determined by standard methods that use traditional approaches; combining both provides a possibility for further optimizations.
