Abstract
A shock protection device having opposing pluralities of frangible splines separated by an annular groove disposed in an internal splined opening in a drive hub, the splines for intermeshing engagement with a splined end of a drive shaft for transferring rotary motion to a cutter head from a driveline. Variation in the width of the annular groove enables precise adjustment of the fracture torque for the shock protection device beyond the adjustment possible through variation in the number or configuration of the individual splines.
