双盘式渐开线测试仪无回差传递杠杆的设计

The Design of the Transmission Lever of no Hysteretic Error in Double-disc Measuring Apparatus of Involutes Tooth Profile

在齿轮若干精度指标的测量中,渐开线圆柱齿轮的齿形检验是其中一个重要的检测项目,而且难度较大。双盘式渐开线测试仪就是测量标准齿轮渐开线齿廓的高精度仪器之一。本文简要介绍了双盘式测试仪的测量原理,并对测量仪的所采用的"无回差传递杠杆"进行了理论和实验验证,证明此机构对微量的误差来说,灵敏度很高,可以满足基准级渐开线测试仪的要求。

The technology of involutes tooth profile measurement for master gear is important and difficult in its all precision indexes.The double-disc measuring apparatus of involutes tooth profile was provided with high accuracy.The principle of the measuring apparatus was introduced and analyzes the feasibility of 'The Transmission lever of no hysteretic error'which was used in the Measuring Apparatus was analyzed.In conclusion,it was proved very sensitive to micro-error and can feel content to the measuring apparatus of involutes tooth profile in benchmark step.Benchmark.
