ABSTRACT:
A linear friction welding oscillator consists of a plurality of individual linear oscillators which are ganged together so as to operate in unison. The total force exerted by the composite oscillator is thus the sum of the output forces of the individual oscillators. The individual oscillators produce variable amplitude, linear reciprocation of an output ram by converting rotary motion into linear motion using conversion/coupling means such as a swash plate connected by a bending elements to drive a crank. Each of the individual oscillator cranks is rotatably engaged with the output ram so as to transmit to it axial, reciprocal movement due to the angular alignment of the swash plate axis with the ram. All of the individual oscillators are mounted in a common frame in which they can be swung in unison so as to vary and control their individual movements in synchronism.
