ABSTRACT:
A flowmeter connecting rod assembly for use with a positive displacement radial piston flowmeter. The flowmeter includes pistons mounted radially about the central axis of an indicator shaft. The indicator shaft has an eccentric crank pin extending from its lower end parallel to the central axis. Each piston has a wrist pin for connection to the crank pin by a connecting rod. The ends of the connecting rod have enlarged holes sized for mounting ball bearings therein. The connecting rod is connected to the crank pin and the wrist pin by the bearings. The wrist pin ball bearing is secured to the connecting rod by a rivet assembly which clamps onto its outer race. The crank pin ends of the connecting rods are positioned along the axis of the crank pin by spacers and are kept in place by a spring clip.
