Abstract
An in-line oscillating cam assembly which includes a housing, a cam shaft having a longitudinal axis, and a pair of eccentric drive cams longitudinally spaced apart from each other and mounted on the cam shaft eccentrically out of phase. The pair of drive cams have opposed circumferential chamfered surfaces oriented at an inclined angle relative a plane perpendicular to the longitudinal axis of the cam shaft. The cam shaft is supported upon the housing and is also rotatable about the longitudinal axis. Further included in the assembly is a follower shaft spaced apart from and parallel to the drive shaft, and a cam follower longitudinally fixed to the follower shaft and extending between the pair of drive cams. The cam follower has a pair of opposed frustoconical follower-surfaces engaging the chamfered surfaces of the pair of drive cams. Thus, rotating one of the cam shaft and follower shaft causes the other one of the cam shaft and follower shaft to axially oscillate.
