Customers can obtain calculation results from Bearinx significantly faster, which speeds up their development processes.&nbsp;<\/p>\n\n\n\n<p>Stephan Evert, Head of Bearing Analysis Tools Development in Schaeffler\u2019s R&amp;D Bearings department, emphasised the advantages: \u201cREXS allows us to reduce the outlay for linking CAE tools and simulations in the relevant software systems, while simplifying the IT architectures at the same time.\u201d&nbsp;<\/p>\n\n\n\n<p>He went on to explain: \u201cREXS can be used by the gearbox sector as a standardised data container for the generation of digital twins.\u201d<\/p>\n\n\n\n<p><strong>Faster application development in gearbox design<\/strong><\/p>\n\n\n\n<p>Gearbox manufacturers with a high proportion of customer-specific application development will benefit greatly from being able to digitally exchange data with their suppliers.&nbsp;<\/p>\n\n\n\n<p>\u201cThe objective is to allow different systems that have their own focal points in terms of calculation to be used efficiently and effectively,\u201d explained Dr. Heinrich Bolz, Head of Calculation and Simulation in Gear Unit Development for SEW-EURODRIVE.&nbsp;<\/p>\n\n\n\n<p>Regarding the open-source project, he continued: \u201cWith REXS, gearbox data can be transferred quickly and without errors, which means the interface makes an essential contribution to the optimisation of our innovation process.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A complete virtual representation of drive trains and gearboxes is only possible when gearbox, rolling bearing and gearing specialists can digitally link their simulation models together.
