摘　　要：为了降低直齿圆柱齿轮端面的辐射和传导噪声,在前人研究的基础上,选用具有黏弹性特性的高分子材料——丙烯酸酯和聚氨酯,分别将其尽可能均匀地涂抹在直齿圆柱齿轮的两侧端面,对比了涂抹不同材料、不同涂抹厚度的降噪结果。试验结果表明,选用的高分子材料均能够降低直齿圆柱齿轮的辐射噪声;在一定厚度范围内,降噪幅度随材料涂抹厚度的增加而增加。In order to reduce the radiation and conduction noise of the end face of spur gears,on the basis of previous studies,the polymer materials with viscoelastic properties,acrylic ester and polyurethane,are selected and evenly coated on the end face of spur gears.The noise reduction results of different materials and different coating thicknesses are compared.The test results show that the selected polymer materials can reduce the radiated noise of spur gears.Within a certain thickness range,the noise reduction increases with the increase of the coating thickness of the material.
