ABSTRACT:
The zero backlash spline coupling for a pair of shafts includes a first shaft having an integral flange and an internal frusto conical surface mateable with the frusto conical surface of a radially cut collar. The collar has internal spline teeth with one tooth on either side of the radial cut eliminated. The collar encircles a second shaft which has externally cut splines and abuts an internally spline-toothed keeper which also encircles the second shaft. Bolts passing through the keeper and into the flange draw the two together and force the collar to friction seat in the first shaft and lock onto the splines of the second shaft while providing a positive torque retention load on the bolts.
