VIBRATORY MECHANISM INCLUDING DOUBLE HELICAL KEY SHAFT, COMPACTOR INCLUDING VIBRATORY MECHANISM, AND METHOD OF OPERATING A VIBRATORY MECHANISM

摘要

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.
