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 = – depending on the type of motor suspension. The bearing loads. | The Design of Rolling Bearing Mountings PDF 1 8 Contents Rolling Bearings The Design of Rolling Bearing Mountings Design Examples covering Machines Vehicles and Equipment Publ.

For this reason the brief texts concentrate on the rolling bearing aspects of the applications. The operation of the machine allows conclusions to be drawn about the operating conditions which dictate the bearing type and design the size and arrangement fits lubrication and sealing. Important rolling bearing engineering terms are printed in italics. At the end of this publication they are summarized and explained in a glossary of terms some supplemented by .
