A group of nuts can be considered in the calculation. The nuts are assumed to be connected to a rigid shaft and housing. The loads or displacements are given for the origin of the bearing group instead for each single bearing.
A relative position can be entered for each bearing. An axial offset allows the definition of pretension in the system. The offset is an additional movement of the ball nut. The displacements, forces and moments under loading are applied at the reference position 0. So in most cases the positions should be chosen symmetrically around zero.
Additional bearings can be added using the -button. A row can be deleted using the -button and the -button clears all inputs.
With the context menu (right mouse button) in the table, several results values can be shown in the table. This allows seeing quickly how load or life is distributed among the nuts.
