齿轮双面啮合综合检查仪(简称双啮仪),是将被测齿轮和测量齿轮(其精度较被测齿轮高2～3级)作无侧隙的紧密啮合,测量其中心距的变动,以达到综合测量的目的。双面啮合时,齿轮转一转,中心距的变动即能反映齿轮运动精度的误差。双啮仪由于结构简单、操作方便、测量速度快等特点,因而被广泛应用。然而,国产的双啮仪只装有一只百分表,以显示中心距的变动,缺少象国外双啮仪所具备的自动记录装置。这样稳定性差、读数精度低、且不便于分析比较和保存测量数据。因此,我们
The gear double-sided meshing comprehensive tester (hereinafter referred to as double nip), is the measured gear and measuring gear (the accuracy of the measured gear higher than 2 to 3) for no backlash close meshing, measuring changes in its center distance, In order to achieve the purpose of comprehensive measurement. Double-sided meshing, the gear turn, change the center distance that can reflect the error of gear movement accuracy. Because of its simple structure, easy operation and fast measuring speed, it is widely used. However, the domestically produced doubles meter is only equipped with a dial indicator to show the change of the center distance, and the lack of an automatic recording device as the foreign doubles instrument has. This poor stability, low reading accuracy, and not easy to analyze and save the measured data comparison. therefore, we
