Abstract:
1. A coupling device comprising: a drive member rotatable about an axis; a driven member substantially aligned with the drive member and selectively rotatable about the axis; a first flyweight and a second flyweight, each coupled to the drive member and each movable between a first position and a second position in response to the rotational speed of the drive member; a synchronizing member positioned to couple the first flyweight and the second flyweight such that the first flyweight and the second flyweight pivot from the first position to the second position at about the same speed; and a clutch member movable between a disengaged position and an engaged position in response to movement of the first flyweight and the second flyweight between the first position and the second position, wherein the synchronizing member includes a gear that engages the first flyweight and the second flyweight, and wherein the clutch member is disposed within a housing having an aperture through a radially outward surface, at least a portion of the clutch member being removable through the aperture without changing the alignment between the drive member and the driven member.
