Abstract: A crankshaft is formed with stub web portions for attachment of balance weights. The crankshaft bearing surfaces are ground and then the weights are electron beam welded to the web portions, which have a stepped configuration to enable indexing for sequential weight welding. After hardening trimmer plates are fastened to the weights axially of the crankshaft to complete the balancing. This provides an inexpensive, easily machined, accurately balanced crankshaft.

Abstract translation: 曲轴形成有用于连接平衡重的短纤维网部分。 曲轴轴承表面被研磨，然后重物是电子束焊接到腹板部分，其具有阶梯状构造以能够进行顺序重量焊接的分度。 硬化后，修剪板被固定在曲轴轴向的重物上，以完成平衡。 这提供了一种廉价，容易加工，精确平衡的曲轴。
