In Lanchester's design, two balance shafts rotated in opposite directions at twice the crankshaft speed to cancel out the niggling secondary vibrations.
Lanchester的设计中，两个平衡轴以两倍于机轴转速，反向地转动，抵消了无用的次生振动。

For the secondary forces to be in balance, the rods connecting the pistons to the crankshaft would have to be of infinite length.
