Mechanical vibration and noise not only hurt system of human being but also threaten the precise of instrument, and damping technology is one of the most efficient methods to control them.
振动和噪声不仅危害人的听觉系统，还会加速机械结构的老化，影响设备及仪表的精度和使用寿命，阻尼减振技术是有效控制振动和噪声的方法。
The vibration and noise brought out in mechanical system comes primarily from that produced by gears.
齿轮传动所引起的振动和噪声是机械传动振动和噪声重要来源之一。
No noise: the low speed motor reduced the mechanical vibration, totally solved the noise problem between gear and motor high speed running.
静音：超低速同步电机减少了机械振动，彻底消除齿轮及电机高速运转的噪声。
