Vibratory apparatus

A vibratory apparatus including:

• a housing;
• a shaft mounted with respect to the housing for rotation about a shaft axis;
• first and second eccentric weights supported by the shaft for rotation about the shaft axis;
• a first drive gear fixed with respect to the shaft;
• a second drive gear formed on the second weight and axially spaced from the first drive gear;
• and
• first and second transition gears engaging the drive gears.

A vibratory apparatus including:

• a housing;
• a shaft mounted with respect to the housing for rotation about a shaft axis;
• first and second eccentric weights supported by the shaft for rotation about the shaft axis;
• the second weight includes a pair of axially-spaced weight members joined by a rib and defining a cavity between the weight members;
• the cavity has a cavity axial dimension;
• and
• the first weight has a first axial dimension less than the cavity axial dimension, thereby permitting the first weight to rotationally move in the cavity.

A vibratory apparatus including:

• a housing comprising first and second closures and a central member interposed between the closures;
• a shaft mounted in the housing for rotation about a shaft axis;
• a first eccentric weight affixed to the shaft for rotation therewith;
• a second eccentric weight supported on the shaft by a first bearing set, thereby permitting the second weight to rotate independently of the shaft;
• a motor mounted with respect to the housing and having a motor shaft coupled to a transition gear;
• a first drive gear fixed with respect to the shaft and engaging the transition gear;
• a second drive gear fixed with respect to the second weight and engaging the transition gear;
• and wherein:
• the shaft and the weights comprise a rotating assembly;
• the rotating assembly is supported in the housing by a second bearing set.

A vibratory apparatus including:

• a housing;
• a shaft mounted with respect to the housing for rotation about a shaft axis;
• first and second eccentric weights supported by the shaft for rotation about the shaft axis;
• wherein the first weight is affixed to the shaft and wherein the first weight and the shaft rotate in a first direction and the second weight rotates about the shaft in a second direction simultaneously with the first weight.
