CAF MiiRA (Motion and Intelligence in Railways) designs, manufactures and maintains railway wheelsets and their components. With a great deal of expertise in supply and repair of gear units, they are the only wheels and axles manufacturer able to design and assemble the complete wheelset.
With durability a key industry priority, CAF MiiRA’s gearbox engineering team have worked with Romax Technology on several projects to ensure optimum gear design for reliable performance and reduced noise. One recent project saw Romax working with CAF MiiRA to optimise gear micro geometry to meet demanding stress targets, and minimise transmission error and edge loading. An optimised design was specified, and the process has ultimately enabled CAF to make their use of simulation more effective, improve their understanding of their products, and save operating costs while de-risking new designs.
Mikel Oyarbide, Gearboxes Projects Engineer from CAF MiiRA comments: “Romax brought a lot of value to our design process, including Right First Time™ design and improving our understanding of our products, which in turn means that lead times can be achieved, and we save cost and test rig availability.”
