1) Types of Splines
The term “spline” provides an umbrella term for all profiles and the splines can be divided into the following three
2) Features of Helical Gear
The angled teeth engage more gradually than do spur gear teeth, causing them to run more smoothly
and quietly.With parallel helical gears, each pair of teeth first make contact at a single point at one side
of the gear wheel, a moving curve of contact then grows gradually across the tooth face to a maximum
then recedes until the teeth break contact at a single point on the opposite side.
