1) Features of Helical Gear
The benefit of a helical gear train is that the teeth of the gear engage in small increments as opposed to the entire face engaging at once.
This reduces the noise that is normally caused as gears transfer power.
2) Description of Spline Shaft
While it is possible to achieve this result with major diameter/minor diameter fits of the mating splines.
The true centering effect can only be achieved by using involute splines.
This involute, or “side fit” profile is the most common used spline in production today.
