ABSTRACT:
An overload coupling has a first coupling member, a second coupling member which is rotatable relative to the first coupling member but fixed axially with respect thereto and a third coupling member rotatably disposed between the first and second coupling members and axially movable between a first position in which torque transmitting means provided on the second and third coupling members are in engagement and a second position in which the torque transmitting means are disengaged. A plurality of torque transmitting balls are circumferentially spaced in the first coupling member and are spring biased axially toward the second coupling member. The third coupling member is provided with a plurality of arcuate recesses to receive the torque transmitting balls and each of these recesses has a torque transmitting portion and a free-wheeling portion. The axial distance between the torque transmitting and free-wheeling portions is greater than the distance between the engaged and disengaged positions of the third coupling member. The first coupling member is further provided with a plurality of spring biased bolts which are engageable with the third coupling member to urge the third coupling member into its engaged position during movement of the torque transmitting balls from their free-wheeling positions to their torque transmitting positions in the recesses.
