Abstract
This invention relates to a method of eliminating rotation of a snap ring, and more specifically, to an anti-rotation feature on the outer diameter of a gapped snap ring. The invention prevents rotation of the snap ring within the housing in which it is assembled. This is done to prevent the gap, which causes a mechanical imbalance, from changing position within the housing. This enables fixed position balancing mechanisms to be effective in balancing the assembly. A locking feature is provided that is adapted to lock the snap ring in a snap ring groove, preventing the snap ring gap from rotating within the snap ring groove. The locking feature comprises at least one locking feature crest positioned on the outer diameter of the snap ring.
