目前，人们较重视应用减振材料作为减少机械振动和噪声的一种手段。减振金属材料的振动衰减性能好，一般认为，对于减少振动和降低噪声较为有效。球墨铸铁是一种具有较好减振性能的材料，用于制造齿轮的球铁材料很多：如铁素体型、珠光体型和贝氏体型球铁等。它们有不同的... At present, people attach more importance to the application of damping material as a means of reducing mechanical vibration and noise. Vibration damping metal vibration damping performance, generally considered to reduce vibration and reduce noise is more effective. Ductile iron is a material with good damping properties. Nodular cast iron used for making gear has many materials such as ferrite, pearlite and bainitic ductile iron. They have different ...
