ABSTRACT:
An upright post has a rounded bearing member at its upper end provided with a discharge port through which air, supplied at the lower end of the post, exits. A cylindrical bearing body is formed with a vertical bore extending therethrough so as to accommodate therein a longitudinal portion of the upright post, the bore being slightly larger in diameter than the post. The bearing body supports upper and lower balancing mechanisms, each including a plate or platform having four quadrantly located sensing ports. A bearing cap overlying the rounded bearing member is affixed to the platform of the upper balancing mechanism. The platform of the upper balancing mechanism removably rests on the top of the bearing body and has mounted thereon a pair of reversible air motors, each having a shaft and shiftable weight threadedly disposed on the shaft. The platform of the lower balancing mechanism is fixedly attached to the bearing body and carries two adjustable weight means corresponding to the air motors, shafts and weights of the upper balancing mechanism. Pneumatic power amplifiers, which are responsive to differences in pressure, are connected to the upper four sensing ports and additional pneumatic power amplifiers are connected to the lower four ports. Circumscribing the midportion of the bearing body is an annular ring for supporting the wheel to be balanced.
