Methodology for Requirement-driven Tolerance Specification of Bevel Gears

This paper presents a methodology, which facilitates to analyze the operating behavior of bevel gears under consideration of production-caused deviations. The approach supports an engineer in understanding the functional relationships between the individual parameters of the system in an early phase of product development. As a result, requirement-driven tolerances for gearing and parts can be defined. These optimized specification limits are expected to reduce the bevel gears noise level during operation. An example of an automotive rear axle drive was used to evaluate the methodology.
