    摘要： A rotating power transmission member engaged with a segmented power transmission means is balanced to counteract vibratory torques and forces by three tuned pendulum balance weights spaced 120* apart. A specific application is to a crawler vehicle with tuned pendulums in the track drive, bogey and idler wheel assemblies to balance and counteract vibratory forces and torques transmitted to the wheels by the track. The balance weights are built into each wheel assembly and are tuned to the same order as the number of teeth on the track drive wheel so that the balance weights produce counterforces and countertorques, per revolution, equal to those from the number of track segments, per revolution, causing the imbalance forces and torques. In the case of the idler and bogey wheels, the tuning order is the effective pitch circumference divided by the track pitch.
