ENGINE BALANCE APPARATUS AND ACCESSORY DRIVE DEVICE

摘要

A balancing mechanism (10) for an engine that has a rotating crankshaft (20) an reciprocating pistons (24, 25) such as those engines used in automobiles, aircrafts, boats, piston-driven compressors, piston-driven slider crank mechanisms, etc. The present balancing mechanism may comprise a first balance mass (82) non-rotatably affixed to the crankshaft and a second balance mass (110) rotatably supported on the crankshaft. A driver assembly is affixed to crankshaft to cause the second balance mass to rotate in a direction that is opposite to the direction in which the crankshaft is rotating. The driver assembly may include auxiliary gears configured to transport rotary power to auxiliary components.
