Abstract

A vibratory mechanism for a compaction machine, the vibratory mechanism including first and second eccentrics, and a key shaft including oppositely helically splined portions. The first helically splined portion is complimentary to and disposed at least partially within a first internally helically splined bore of the first eccentric. The second helically splined portion is complimentary to and disposed at least partially within second internally helically splined bore of the second eccentric. The key shaft is disposed to linearly translate within the helically spined bores to cause the second eccentric to rotate in a direction opposite the first eccentric.

First claim

I claim:

1. A vibratory mechanism for a compaction machine, the vibratory mechanism comprising:
a first eccentric defining a first internally helically splined bore therein;
a second eccentric defining a second internally helically splined bore therein; and
a key shaft including a first helically splined portion and a second helically splined portion, the first helically splined portion being complimentary to and disposed at least partially within the first internally helicall…
