Gear noise control starts at the design stage and continues through every manufacturing step.
Our approach includes:
- (1) Micro-geometry optimization – we design tip relief and lead crowning to compensate for tooth deflection under load, reducing transmission error which is the primary source of gear whine.
- (2) Precision manufacturing – we maintain tight control over pitch deviation, runout, and tooth-to-tooth spacing errors using AGMA Q10 or DIN 6 standards as a baseline.
- (3) 100% inspection – every gear set undergoes double-flank composite testing and single-flank rolling testing to measure transmission error. We provide FFT (Fast Fourier Transform) spectrum analysis to identify and eliminate harmonic orders that cause objectionable noise.
- (4) Contact pattern verification – we adjust cutting machine settings to achieve a centralized, stable contact pattern that does not shift under load. Our goal is to deliver gears that meet your specific decibel targets in the actual assembly.
