To ensure that gear reducers pass factory testing, it is essential to address the issue of intermittent high noise levels. Tests using the ND6 precision sound level meter indicate that low-noise gear reducers register 72.3 dB(A K)), meeting factory standards, while high-noise gear reducers reach 82.5 dB(A K)), failing to meet the requirements. Through repeated testing, analysis, […]
