Description: |
| Abstract:
A hollow tubular member of a ductile material connects driving and driven shafts to each other through having equally angularly spaced portions deformed for disposition within equally angularly spaced grooves in each of the driving and driven shafts. By selecting the size of the grooves and retaining means, which are carried by the hollow tubular member but movable into the grooves for cooperation with the equally angularly spaced portions of the hollow tubular member to retain the portions in the grooves, there is no reliance on friction so that the coefficient of friction can be exceeded in the transmission of torque. The hollow tubular member provides a rigid connection between the driving and driven shafts so that there is no backlash. |
