Walk-behind compaction roller incorporating noise reduction measures
A vibratory compaction roller has a pretensioning mechanism that exerts a pretension or biasing force between the drum and the motor housing that inhibits relative axial movement between the output shaft of each drive motor and the associated motor housing, thus significantly reducing the generation of noise that would otherwise be created during machine operation. The pretensioning mechanism may take the form of one or more springs positioned between the drum and a drum support that also supports the motor. Bushings are provided between the springs and the drum to accommodate rotational motion between each spring and the drum. Alternatively, the pretensioning mechanism may be provided on a side of the drum opposite the motor and may pull the drum away from the motor.
