Description:

In the attached models a TRB set (2 TRBs in back-to-back arrangement) with a CRB is used and an external radial load is applied. 

The models will demonstrate and explain the effect of a change in the distance between the two TRBs (and a difference in operating clearance in the TRB set) on the load distribution on the different bearings in the shaft system.

A detailed explanation can be found in the report of the corresponding model.

• Option 1: no external load
• Option 2: external radial load of Fy = 5000 N
• In SimPro Expert: the clearance of the TRB set is varied in three steps
