It lays down the following fundamental principles: a) standardized uniform pressure angle of 30°, Spline shafts differ by the types of grooves or tongues that transmit torque. Constructing Splines. Full Spline Profile PTO Drive Shaft Tight fit, precise tolerances and state of art manufacturing processes allow Weasler to provide drive shafts with minimal run out and greater performances. Given a specific arrow spine, an arrow that is shorter will be more rigid than a shaft of the same spine that is longer. Load Compliance with recommended assembly tolerances is essential in order. We also recommend full complement gaging for involute splines, especially in difficult to reach splines and harder grades of material. When looking at the numbers for a given spline, the closer the min.
