Abstract
A connection between a shaft and a hub includes a straight bore in the hub, a plunger bore in the hub intersecting the straight bore, a straight end on the shaft matching the straight bore in the hub, a longitudinal notch in the straight end of the shaft which faces and cooperates with the plunger bore in defining a plunger chamber between the shaft and the hub, a plunger moveable back and forth in the plunger bore, and a spring urging the plunger toward the shaft. A hub side of the plunger chamber defined by the plunger bore converges with a shaft side of plunger chamber defined by the longitudinal notch. The spring biases an enlarged head of the plunger toward the apex of the plunger chamber. The angles of convergence between the plunger bore and the straight bore, and between the hub side and shaft side of the plunger chamber, are calculated to assure that the enlarged head of the plunger positively resists forced dislodgement of the shaft from the hub by becoming progressively more tightly wedged between the hub side and the shaft side of the plunger chamber.
