A new version of the MESYS shaft and rolling bearing analysis software including new functionality is available
A new version of the MESYS shaft and rolling bearing analysis software including new functionality is available. The bearing analysis software allows the calculation of the load distribution within the bearing and bearing life according to ISO/TS 16281 and it is integrated in a shaft system calculation with additional possibilities like modal analysis, strength calculation for shafts and interfaces to gear calculations. Currently the software is used by customers in 30 countries on four continents.
General Extensions
Some start parameters were added to allow an easier integration with other systems. Using the COM-Interface, now the parameter calculation can be called to generate additional results. The default for the Help system was set to an external viewer, which can also be started from network drives. Custom formulas can now be used within the parameter variation.
Extensions in the Bearing Calculation
The bearing databases with catalog data from Schaeffler and SKF were updated. Schaeffler provides the number and dimensions of rolling elements, and the database has to be provided in encrypted format with hidden internal geometry. For the SKF database the dimensions of the rolling elements are still approximated. The detail geometry like curvatures or profiles are still approximated in both cases.
Regarding the bearing databases including internal geometry, the databases from CSC and HQW/Barden are unchanged from the last version. On request, additional databases are available from some bearing manufacturers, for example from GMN or IBC.
As new bearing types, toroidal roller bearings anddouble row thrust cylindrical roller bearingswere added. In contract to barrel roller bearings, toroidal roller bearings have no shoulders and allow larger axial displacements. The radial clearance is dependent on axial displacements. The double row thrust cylindrical roller bearings have the same roller dimensions for both rows (see photo above).
The track roller calculation with elastic outer ring is now also supported for double row deep groove ball bearings. Previously, a configuration of two single row bearings had to be used.
Interference fits affect the operating clearance of bearings. As there had been some customer requests now also multi-layer interference fits can be defined. For the inner and outer ring fit several layers using different materials can now be defined. Influence of centrifugal forces and temperature is considered.
