ABSTRACT:
A mechanism for use in linear friction welding has a drive-shaft (10) rotatable about a first longitudinal axis (12). An eccentric portion (10A) for locating a cam member (18) has a second longitudinal axis (16) spaced a distance d from the longitudinal axis (12) of the drive-shaft (10). The cam member (18) has a third longitudinal axis (20) spaced distance d from the second axis (16) of the cam member (18). A connecting-rod (24) is located via a big-end bearing (26) on the periphery of the cam member (18). When the drive-shaft is rotated with the third axis (20) of the cam member (18) displaced from the longitudinal axis (12) the connecting-rod reciprocates. If the cam member (18) is rotated about the second axis (16) of the eccentric portion (10A) until the longitudinal axis (12) and the third axis (20) of the cam member (18) are coincident the connecting-rod stops reciprocating.
