  • The collective load is the basis for determining the average speeds (2,387 min–1) and the average driving speed (111 km/h). For each of the load cases the tooth load acting on the pinion and the reaction loads from the bearings have to be calculated both for forward and backward motion (percentage times 50 % each). In addition to these forces, the bearings are subjected to loads due to the rotor weight, the unbalanced magnetic pull, unbalanced loads and rail shocks. Of these loads only the rotor weight, GL, is known; therefore, it is multiplied by a supplementary factor fz = 1.5...2.
