The flexible 1-station crankshaft balancing machine from Hofmann consists of a combined measuring and drilling stand and is designed for automatic balancing of symmetrical and asymmetrical crankshafts in two planes. Balancing an engine requires simulating the weights of the pistons, piston pins, rings, connecting rods, engine bearings and even the oil with what is known as a bobweight (set pictured left). Build a Balancing Machine. Once the balancer begins spinning the crankshaft, each column of the balancer, which holds the crankshaft in place, has sensors on it to pick up vibrations and movement outside the range you’ve set. When a crankshaft is designed for external balance, the offset-weighted dampener (or balancer) and weighted flywheel must be attached to the crankshaft during balance spinning. When the counterweights alone can be made to balance the crankshaft, the crank is said to be “internally balanced”. Corrections are then made by adding or removing weight at the crankshaft’s counterweights. Building a Dynamic Balancing Machine Erbessd Instruments 2.
