RomaxDesigner R20

ENGINEERING INSIGHT
Easily and quickly build a full parametric electro-mechanical system model, including motors, gears, shafts, housings and bearings.

Cutting-edge rolling element bearing analytical methods give the insight required to design and select bearings for optimum performance and durability, as part of a system model.

Online bearing catalogues from SKF, Schaeffler, Timken and JTEKT give access to more than 60,000 bearings. Alternatively, bearings can be custom-edited or designed from scratch.

BETTER COLLABORATION
Romax Spin works seamlessly across the Romax Nexus product family – models can be shared with engineers focusing on system durability, efficiency, NVH and electrification to encourage truly collaborative working across the organisation and beyond.

Bearing suppliers and their customers can now work more collaboratively and more independently, using the same tools and sharing data.

Users can create and share their own bearings databases, with IP protection for sensitive details.

Bearing Simulation Better collaboration

With the rise of electric vehicles, bearings are operating under increasingly high speeds. Combined with low load conditions, this can lead to a dynamic phenomenon known as bearing skidding. In certain circumstances, bearing skidding can generate excessive frictional heat and high surface shear stress, and subsequently result in efficiency issues or premature bearing failure.

Romax’s Bearing Dynamics application uses a novel approach based on transient time-domain analysis to predict the occurrence of skidding in electric-vehicle bearings in a matter of minutes. The model considers structural, thermal and fluid domains, including the influence of centrifugal and gyroscopic effects on rolling- element dynamics, heat generated by the lubricant and associated temperature rise, and rheology and traction behaviour of the lubricating oil.

This application helps design engineers and bearing analysts to avoid damaging failures by designing more reliable bearings and selecting better lubricants, through unique insight of the underlying skidding mechanism and bearing dynamics.
