<p>MECHANICAL SHOCK ARRESTOR Relative axial motion of a pair of strut members is converted into rotation of a shaft which drive a rotatably mounted inertia element. Rotation of the shaft in the opposite direction drives a second rotatably mounted inertia element. The inertia elements are interconnected by a coil spring with the result that the inertia element driven directly by the shaft drives the other inertia element. At a predetermined acceleration, the inertia element driven by the spring will lag, and this change the spring diameter causing the spring to engage a surrounding housing causing a braking action to limit the acceleration, In a second embodiment, the axial strut load is translated through a fixed shaft into rotation of a nut which drives the inertia element The nut also transfers the axial load through the inertia element and a single ball bearing set to the other strut member.</p> |
