Understanding end play and its impact on axial alignment

Jim Bryan EASA Technical Support Specialist End play in an electric motor is the amount of axial movement allowed by the motor s construction This end play is limited by the motor s bearing design The bearing s primary purpose is to locate the shaft radially so it can be aligned to the driven equipment shaft and efficiently transmit torque to the load It is also important that the

The Effects of Rotational Inertia on Automotive Acceleration

This section covers drive shafts and axles/half shafts The principle difference being that axles and half shafts benefit from the final drive ratio and turn even slower than the driveshaft so the effect of rotational inertia is further reduced For drive shafts gear ratio below should be the rear end ratio
