Thermal effects

The thermal effects are considered in two parts as effects on bearing clearances and secondly effects on shafts and FE components.

For Taper roller bearings, under “Internal clearances” tab when mounted and manufactured is selected in the axial clearances section, the effects of ring press fits and radial thermal expansion of the bearing rings, Shafts, Housing and Elements are used to calculate the final operating clearance.

Similarly, for other bearings like Radial Ball, Cylindrical Roller and Needle Roller bearings to which Operating RIC applies, check the box "Calculate operating RIC from manufactured RIC, mean press fits, and temperatures" available on “Internal clearances” tab.

To account the thermal effects on shafts and FE components, one should be choosing the setting for Thermal solver as “Calculate thermal expansion” under Analysis menu >> Settings>> General options >> Static FE solver.
