Abstract
A static unbalance-type balance shaft for rotating machinery such as a vehicle engine includes a longitudinal axis, a first bearing surface disposed away from a first end and a second bearing surface located adjacent a second end. A first balance shaft is disposed between the first end and the first bearing surface, a second balance weight is located adjacent the second bearing surface. A third balance weight is located adjacent the second bearing surface. A connector portion overlaps and extends between the second balance weight and the third balance weight. The third balance weight is positioned on the opposite side of the longitudinal axis from the first and the second balance weights. The connector portion has a substantially I-beam shaped cross section.
