Apparatus and methods for wheel balancing via rotor drive keys

摘要

Apparatus and methods to balance a wheel (12) which rotates around an axle. The wheel (12) has a rim (50) having an outer surface (52) and an opposite interior surface (54) positioned circumferentially around the axle. A plurality of rotor drive keys (60,150) are mounted at the interior surface (54) of the rim (50). At least one rotor drive key (150) having a different weight than the other rotor drive keys (60) is mounted approximately opposite an abnormal weight (160) in order to balance the wheel (12).
