Abstract

The drive coupling, linking drive (4) and driven (7) rotating shafts, comprises a pair of perforated (6a, 6b) crown-wheels (5), (9) interposed by a caged (12) ball (10) race: each of the former locating on abutting ends of the co-axial drive and driven shaft and having perforations regularly spaced on an inner circumference to match the number of balls (10) in the race. The coupling is maintained in elastic axial compression by an axial coil spring (13) between the driven crown wheel (9) and the tool carrying shaft n8), whereby a rebound increase in the coupling torque is achieved. The housing rotates with the drive augmenting inertia and couple torque and ball race cage is of synthetic material.
