Description of Parallel Spline/ Straight Sided Spline
The parallel spline have straight and parallel tooth flanks and various standards number of teeth can vary
from 4 to 12. They can transmit higher torque compared to involute splines and serrations because of their
large tooth thickness from minor to the major diameter of the profile. but might fail ude to fatigue due to stress
concentration in the root of the flanks.
