This rolling bearing calculation calculates the reference life and the modified reference life according ISO/TS 16281 for the following types of bearings:
-
Deep groove radial ball bearings
-
Radial angular contact bearings
-
Axial angular contact bearings
-
Four point ball bearings considered as radial bearings
-
Four point ball bearings considered as axial bearings
-
Radial cylindrical roller bearings
-
Taper roller bearings
The inner geometry of the bearings can be approximated by the software or provided by you. The operating clearance can be specified. The influence of interference fits, temperature and centrifugal load on the clearance can be taken into account. Centrifugal loads on the rolling elements can be considered.
In extension of ISO/TS 16281 the influence of reduced material hardness can be considered according NREL guideline DG03. This includes a check of the case core interface. The lubricant film thickness can be calculated by the software. This is done according Harris: Rolling bearing elements. The loading can be specified as force/moment or displacement/rotation independently for each of the five degrees of freedom. The following results can be found in the report:
-
Reference life according ISO/TS 16281
-
Modified reference life according ISO/TS 16281
-
Load distribution between rolling elements
-
Reaction forces/moments and displacements/rotations
-
Contact pressure for each contact
-
Static safety factor
-
Maximum subsurface shear stress and stress at case core interface
-
Load dependent friction torque for ball bearings based on coulomb friction
-
Change to clearance because of interference fit and temperature
The rolling bearing calculation is available as 32bit windows program running on Windows XP, Vista or Windows 7. In addition to the 32bit version which can be used on 32bit or 64bit operating system also a 64bit version is available. The minimum required processor is Intel Pentium 4 or above.
