1、圆柱齿轮减速器噪音浅析摘要 减速器的主要噪声源是啮合齿轮,影响它的主要因素有:设计参数,制造精度与它的工作条件。由生产实践和实验数据组可知:减速器的噪声值随着中心距的增大,转速的升高和传动比的减小而增大,减速器的工作条件如载荷的变化,润滑剂的种类,传动环节的误差等等也都影响着它的噪声值,而减速器的制造精度(主要是齿轮及箱体的加工精度)则是决定噪声大小的关键因素。 关键词 噪声源 制造精度 减速器 Abstract The noise origin of reducing mechanism is
2、 meshing gear, there are some factors effecting noise: design parameter, manufacturing accuracy and running conditions. The results from production practice and experimental data showed: the noise rating number increased with center distance, rotational speed
3、 increasing and drive ratio decreasing, the running conditions such as load fluctuation species of anti-friction material and driving error effect the noise rating number, but the manufacturing accuracy of reducing mechanism is the key to decide noise low.
