For use in a transmission a shaft was developped consisting of an inner and an outer shaft. The goal of the development was to operate the two shafts at different speeds. Also different oil pressures needed to be maintained in between the shafts. Major difficulties existed in maintaining a capable manufacturability and assembly process.
Different concepts were generated (using CAD, FEA, general flow/ pressure/ strength -calculations). In cooperation with a team at the client containing development, project, manufacturing and process engineers, 2 concepts were chosen. Both concepts were prototyped to review process capability and design feasibility and functionality.
After validation one of the concepts was chosen that fitted best in the customers process.
