ABSTRACT:
A safety coupling which provides positive torque transfer and which disengages above a disengagement torque. The safety coupling comprises two coupling halves which are engaged to restrict axial movement. Some rollers restricted by a first coupling half are urged into recesses in a stop face associated with a second coupling half by a biasing mechanism enabling positive transfer of torque. However, disengagement of the coupling halves is permitted by a relative axial movement of the rollers and the stop face when the bias is overcome, the rollers being free to roll on fixed axes.
