DYNAMIC LOADS ON THE GEARS OF TRACTION MOTORS

The gearings of railcars and locomotives serve in the most severe conditions compared with those of other types, namely, they have to transmit high power to make maximum use of the limited space, depending strongly on the speed and the vibrations. Gears of JNR are relieved and/or crowned at the tooth face in order to avoid a high tooth bearing, which leads to a tooth failure. Calculations and close investigations have been made but it is utterly nonsensical to predict or to calculate the strength of gear without accurate knowledge of the load. It is shown that the dynamic loads on the gears of traction motors passing over rail points have great influence upon the strength of gears in case of Cardan drive (the parallel shafts type) on vehicles for SHIN KANSEN and a new type of drive protecting gears from the dynamic loads is presented.
