Abstract
A linear friction welding system in one embodiment includes a ram configured to oscillate along a welding axis, and a first and second power shaft operably connectable to the ram through a vibrating assembly. Respective motors are configured to drive respective power timing gears fixedly connected to the first and second power shafts. A slave timing gear is operably connected to the first power shaft in variable rotational relationship and to the second power shaft in fixed rotational relationship. The first slave timing gear is configured to be driven by one power shaft to force oscillation of the ram and by the other power shaft to stop oscillation of the ram.
