The balance gear has a damper formed by a cover plate connected to the first side to enclose the recess and contain a plurality of particles therein. A gear and a method of forming a gear is also provided, with the gear having a first sector defining at least one aperture therethrough and a second sector defining a recess intersecting the first side. A plurality of particles are positioned in the recess, and a cover plate encloses the recess to form a damper.
