Vibratory mechanism

A vibratory mechanism 26 is provided for a compacting work machine 10. The vibratory mechanism 26 includes a first/outer eccentric weight 50 and a second/inner eccentric weight 80. The second weight 80 has a cavity 88 with a movable mass 90 that when rotated in a first direction 124 opposes the firs...

Zusammenfassung:	A vibratory mechanism 26 is provided for a compacting work machine 10. The vibratory mechanism 26 includes a first/outer eccentric weight 50 and a second/inner eccentric weight 80. The second weight 80 has a cavity 88 with a movable mass 90 that when rotated in a first direction 124 opposes the first eccentric weight 50 and when rotated in a second direction 126 the movable mass 90 combines with the first eccentric 50. The second eccentric weight 80 is also manually indexable relative to the first eccentric 50 to a plurality of distinct positions giving a plurality of different amplitude vibratory impact forces when rotated in either of the first and second directions 124,126.
