20130139968 | Linear Friction Welder with Helical Groove - A linear friction welding system includes a power shaft defining a power shaft axis and including a first eccentric portion and a first power transfer portion, a power transfer rod engaged with the first power transfer portion, an actuator assembly operably coupled with the power transfer rod and configured to move the power transfer rod axially along the power shaft axis, a crank including a second eccentric portion operably coupled with the first eccentric portion, and a second power transfer portion engaged with the power transfer rod, the linear friction welding system configured such that axial movement of the power transfer rod causes rotational movement of the crank with respect to the power shaft about the power shaft axis, a cam follower operably connected to an outer surface of the second eccentric portion, and a ram operably connected to the cam follower and configured to vibrate along a welding axis. | 06-06-2013 |
20120216938 | Linear Friction Welder System and Method - A linear friction welding system and method in one embodiment includes a first motor configured to rotate a first power shaft, a second motor configured to rotate a second power shaft, a memory including program instructions, and a controller operably connected to the first motor, the second motor, and the memory, and configured to execute the program instructions to identify a first current oscillation amplitude of a ram operably connected to the first power shaft and the second power shaft, determine a second desired oscillation amplitude for the ram, determine a minimum shift in relative angle between the first motor and the second motor to achieve the second desired oscillation amplitude, allocate the minimum shift in relative angle between the first motor and the second motor, and control the first motor and the second motor based upon the allocated minimum shift in relative angle. | 08-30-2012 |
