Abstract
A vibration assembly for a surface compactor machine includes a support subassembly connected to the compacting surface of the surface compactor machine. A primary eccentric shaft is disposed around a secondary eccentric shaft, with the primary and secondary eccentric shafts both rotatable about a common axis of rotation. One or more of primary bearing subassemblies is disposed between the primary eccentric shaft and the support subassembly for supporting the primary eccentric shaft during rotation of the primary eccentric shaft. One or more secondary bearing subassemblies is disposed between the secondary eccentric shaft and the primary eccentric shaft for supporting the secondary eccentric shaft during rotation of the primary eccentric shaft.
