齿轮声辐射特征分析 在选择用不同结构形式的齿轮时，对其特定结构建立声辐射模型，进行动力学分析，对齿轮传动系统噪声进行预先评估。4、齿轮渗碳淬火热处理工艺,采用独特的低噪声齿齿形设计,确保产品的使用寿命。以便根据使用者的不同要求（使用场所，是 否无人操作，是否在城区内，地上、地下建筑物有无特定要求，是否有噪声防护，或无其他特定要求）去满足。
The acoustic radiation characteristic analysis of gear in the selection of gear with different structure forms, set up the acoustic radiation model to its specific structure, carry on the dynamic analysis, and evaluate the gear tran***ission system noise in advance. In order to meet the users" requirements (use sites, unmanned operati, whether there are specific requirements in the urban area, ground or underground buildings, noise protection, or other specific requirements).
减速机动力源运转速度 根据在不同转速条件下对减速机的试验表明，随着减速机输入转速的增加，噪声也将增大。
The experimental study on the structural form of the reducer box shows that the cylindrical box is advantageous to vibration reduction. Under the same other conditi, the noise level of the cylindrical box is 5 dB lower than that of other types of box on ***erage.
对减速机箱体进行共振测试，找出共振位 置，增加适当的筋条（板），可以提高箱体的刚度，减少箱体的振动，实现降噪。多级传动时要求瞬时传动比的变化尽量小，以保证传动平稳，冲击及振动小，噪声低。
By testing the resonance of the reducer box, finding out the resonance and adding appropriate ribs (plates), the stiffness of the box can be increased, the vibration of the box can be reduced and the noise can be reduced. In multistage tran***ission, the change of instantaneous tran***ission ratio should be as ***all as to ensure stable tran***ission, low impact and vibration, and low noise.
