1.5 Module 20CrMnTi Steel Right Hand Pinion Shaft With Involute Spline

1) Types of Splines

 

The term “spline” provides an umbrella term for all profiles and the splines can be divided into the following three

groups based on their flank form.

a) Parallel-sided or straight-sided spline

b) Involute spline

Splines and serrations can also be grouped as fixed spline or flexible spline depending on their relative

axial movement. Fixed spline as the name suggests is a joint that does not move axially such as gears,

pullers, turbine wheels etc.

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.
