Rolling bearing analysis for track rollers

Bending moment is track roller outer ring

Bending moment is track roller outer ring

The rolling bearing analysis according ISO/TS 16281 is assuming rigid races. This is an appropriate approximation if the bearings is mounted on a shaft and surrounded by a stiff housing. In case of a track roller the external load is acting directly on the outer ring which is therefore deformed.

The elastic deformation affects the load distribution in the rolling bearing, which leads to a different hertzian stress and life. In bearing catalogues for track rollers often reduced effective load capacities are provided for this reason. In addition to hertzian stress or life also the bending stress in the outer ring can be critical in track rollers.

Supports for planetary gears with a thin rim are loaded similar to track rollers. There are two loadings deforming the gear body and therefore the load distribution in the rolling bearing.

An extension to MESYS rolling bearing calculation according ISO/TS 16281 for track rollers is now available. The outer ring geometry and the loading on one or more locations can be provided by the user. Deformations and stresses in the outer ring are calculated and shown graphically. The load distribution and the life of the bearing are then calculated with this deformations. Optionally the reduced effective load capacities and the permissible radial load for the outer ring can be calculated.

Further details are available on www.mesys.ch.

MESYS AG in Zurich (Switzerland) is developping software for technical calculations in mechanical engineering. The main focus is the sizing of machine elements as gears or rolling bearings. In addition to standardized software also custom software is developped.

We also support you in design of machine elements especially for gears or we can do ratings according different standards.

New version of MESYS Shaft and Rolling Bearing Calculation is available
A new version of MESYS Shaft and Rolling Bearing Calculation is available now. The bearing calculation now supports an extended method for pressure distribution for all types of roller bearings. This allows the evaluation of different profiles for rollers and races. Serveral possibilities are added to support material influence on load capacities. Permissible stresses for calculation of static capacity or fatigue limit can now be specified for material selections. The shaft calculation
Free online calculation for fits according ISO 286
Free online calculation for fits according ISO 286
The free online calculation for fits according ISO 286 (2010) on the website of MESYS AG was updated. Now the clearance or interference resulting from a fit like H7/n6 is not only shown in numbers but also graphically. So you will realize the position of tolerances at a glance without interpreting numbers. The maximum and minimum clearance or interference are also shown in the graphics. Clerance is shown in green, interference
