C-shaped eccentric snap rings, concentric snap rings, and E-shaped snap rings are produced from excellent forming and heat treatment technologies. In particular, Murata Spring torsion rings and friction rings to reduce vibration noise have earned a good reputation because of their high quality.
Mounting of a snap ring onto an idle gear reduces vibration and noise.
Scissors gears reduce vibration and noise from the sound generated by the tooth beating in a pair of gears. An important part realizing that effect (backlash zero) is the torsion ring. The optimum design for uniform stress is performed by the CAE analysis.
