摘　　要：为降低齿形链传动系统噪声,在分析齿形链传动噪声发生机理的基础上设计了低噪声齿形链。通过设计链板齿廓参数和合理布置聚氨酯链板,有效减小了齿形链传动过程中的啮合冲击。利用封闭力流链式测试试验台,对比测试相同节距的低噪声齿形链和外啮合齿形链分别与标准链轮啮合的噪声,低噪声齿形链紧边啮入点比外啮合齿形链紧边啮入点噪声级平均降低3.5d B、噪声波动幅值降低1.2d B。试验结果证明了低噪声齿形链设计合理,能有效降低噪声并减小啮合冲击。In order to reduce the noise of the silent chain, based on analysis of the noise of silent chain transmission system, a low noise silent chain was proposed. The design of chain plate tooth profile parameters and the arrangement of the polyurethane chain plate can effectively reduce the meshing impact in the process of silent chain drive. Noise of low noise silent chain and outer mes- hing silent chain on same pitch meshing with sprocket was contrast on the closed power flow chain test bench. Low noise silent chain tight side engaging-in point noise level was reduced by 3.5dB ,the noise fluctuation amplitude was reduced by 1.2dB. De- sign method of silent chain is proved to be reasonable,which can effectively reduce the noise and meshing impact.
