<p>A splined shaft head for engaging a splined hub includes first, second and third stages. The first stage has a conical taper on one side, and a cylindrical setback on the other side, which transitions through a tapered shoulder to the cylindrical body of the shaft head. The second stage includes lead spline teeth extending along the cylindrical body to the conical taper. The third stage includes torque-transmitting main spline teeth regularly arranged around the circumference. The shaft head is rotated while being inserted axially into the hub. The first stage allows radial free play and de-centering of the hub so the lead spline teeth find a proper rotational alignment with spline grooves of the hub. Then, the tapered shoulder at the end of the first stage positively centers the hub on the shaft axis, and finally the main spline teeth of the third stage provide full form-locking engagement.</p> |
