摘要
试图通过分析变速器噪声与齿轮精度项目的关系 ,找出降低国产铃木变速器噪声的途径 .选用 1台日本总成、2台国产总成样箱 ,主要从变速器噪声及齿轮零件精度方面进行对比检测 .采用排列图比较分析 ,结果表明 ,制造的零件满足设计要求时 ,装配后总成不一定满足噪声标准要求 .针对国产变速器高速档噪声严重超标的情况 ,利用 CORREL相关系数对总成三、四档噪声值与相应齿轮副误差平均值进行相关分析 ,结果表明与总成噪声密切相关的齿轮精度项目是径向一齿综合误差 ;从齿轮制造工艺着手 ,提出几项降低噪声的措施 ,为国产铃木变速器齿轮降噪提供了技术依据、明确了技术改进的方向 .
This essay tries to find a way to reduce the noise of home made Suzuki gear boxes by analyzing the relationship between gear box noise and gear precision items. Three sample assemblies made at home and in Japan are chosen and comparative testing and checking on gear box noise and gear parts precision are carried out. Comparative analyses of some illustrations show that, on the basis of results from measuring and testing the relationship between gear components and the noise of national or Japanese gearshifts used in Suzuki automobiles, parts that reach the design demands don't mean that the gear box is definite to be up to the noise standard. The item affecting gear accuracy, which contributes a lot to the noise of gear box, is a radial tooth to tooth composite error. results from the relative analysis of three grade and four grade value of gearshift noise and the average value of error in corresponding gear pair, by utilizing the relative coefficient of “CORREL” . Based upon close study of the manufacturing process and workmanship of gears, proposals are put forward for reducing noise, in the hope of establishing technical grounds for the reduction of the noise of home made Suzuki gears.
