ABSTRACT:
An apparatus and method for a turbine wheel assembly for a pneumatic rotary vibrator that provides a selectable force output while being removably retained on a vibrator shaft member. The turbine wheel assembly is mounted inside of a generally circular interior chamber of a pneumatic vibrator housing. The turbine wheel assembly includes: (1) a turbine ring that has an outside diameter, an inside diameter and a face width, (2) a sleeve member that is round and tubular, (3) an intermediate weight ring assembly that has an outer circumference, an inner circumference, and a predetermined face width, The weight ring assembly is formed by a plurality of wedge shaped segments. The plurality of wedge shaped segments include a predetermined quantity of heavy material segments and light material segments and by controlling the proportion of the total mass of the heavy material segments with respect to the total mass of the light weight material segments in the weight ring assembly will control the output force of a single model of the pneumatic vibrator.
