| 摘要:通过对8DKM-28柴油机相关部位的噪声测试,得到了8DKM-28柴油机的噪声分布。结果表明,该型柴油机泵传动齿轮箱部位为最大噪声源。相应对策是:将齿轮制造工艺改进和设计改进结合起来,重点控制齿轮基节偏差等齿形精度、机身中间齿轮轴孔和定位销孔的位置度和同轴度；控制滑油压力；及排气消音器的设计、选型工作。 |

| Abstract:Through noise test on 8DKM-28 diesel engine’s relative parts, the noise distribution of 8DKM-28 diesel engine was obtained. The results show that the main noise comes from the pump drive gear box. Through analysis, the solutions are given, which combines improvement on both manufacturing process and design. The key points are controlling gear’s precision such as base circle pitch deviation, controlling true position and concentricity of shaft hole of intermediate gear and dowel hole; controlling lube oil pressure; as well as the design of exhaust silencer and type-selecting. |
