The involute curve remains the industry standard for most precision gears due to its tolerance of center distance variations. In precision applications, minor deviations from the ideal involute profile introduce Transmission Error (TE). TE is the primary source of high-frequency vibration and acoustic noise.
Precision gears require materials that offer high fatigue strength, wear resistance, and dimensional stability over time. Material Selection
