Design Concepts
This concept uses spring loaded protrusions in the part connecting the shaft to the distributor. Rigid protrusions inside the shaft allow both parts to engage and transmit power during normal operation. When overloading occurs, the springs compress and are allowed to move past the protrusions in the shaft. Once the protrusions have moved past each other, the system will attempt to re-engage after a 360 degree rotation. The protrusions are offset to maintain angular alignment upon re-engagement.
