Linear friction welding system with phase change assembly
First Claim
1. A linear friction welding system, comprising:
- a ram configured to vibrate along a welding axis;
a cam follower operably connected to the ram;
an eccentric including an eccentric outer periphery operably engaged with the cam follower, and an inner periphery;
a first power shaft slidingly engaged with the eccentric;
a second power shaft eccentrically engaged with the inner periphery;
a first timing component configured to drive both the second power shaft and a phase change assembly drive shaft;
a motor configured to drive the first timing component; and
a phase change assembly driven by the phase change assembly drive shaft, wherein(i) the phase change assembly is configured to drive the first power shaft,(ii) the phase change assembly is configured to be driven by the first timing component,(iii) the phase change assembly is not driven by the second power shaft, and(iv) the phase change assembly is configured to be movable between a first configuration defining a first phase relationship between the first power shaft and the second power shaft, and a second configuration defining a second phase relationship between the first power shaft and the second power shaft.

Abstract
A linear friction welding system in one embodiment includes a ram configured to vibrate along a welding axis, a cam follower operably connected to the ram, an eccentric including an eccentric outer periphery operably engaged with the cam follower, and an inner periphery, a first power shaft slidingly engaged with the eccentric, a second power shaft eccentrically engaged with the inner periphery, a timing component operably connected to the first power shaft and the second power shaft, a motor configured to drive the timing component, and a phase change mechanism engaged with the timing component and movable between a first position defining a first phase relationship between the first power shaft and the second power shaft, and a second position defining a second phase relationship between the first power shaft and the second power shaft.
