【摘要】 通过对汽车分动器主被齿轮啮合间隙的分析和研究,得出壳体调整垫片的厚度对分动器总成性能影响的实质。基于相对测量原理,研制出分动器壳轴承调整垫片预选系统,对测量数据进行分析以及不确定度评定。实践证明,该系统能有效选取满足配对弧齿轮装配的合适垫片,改善了生产工效和装配质量,为汽车分动器生产的关键工序提供了可靠保证。更多还原

【Abstract】 This paper analyzes and researches the gear backlash of the drive and driven gears on automotive transfer case,and achieves the truth that the washer affects the performance of transfer case.Based on relative measurement,it develops washer-selecting system of bearings on the shell of transfer case,and analyzes measured data and evaluates uncertainty of the input quantity.After practice,it proves true that the system could effectively select the corresponding washers to meet the assembly requirement of gear pairs with curved teeth,and better efficiency and assembly quality.The washer-selecting machine provides a reliable guarantee to the key production processes of transfer case.更多还原
