| 针对编码器在检测过程中因安装误差产生安装偏角的情况，分析了安装偏角、旋转角度和测量误差之间的关系。建立由安装偏差引起的非同心检测系统安装偏角的模型，通过实验分析3种不同程度的安装偏角$ 0^ \circ～{0.002^ \circ } $、$ 0.1^\circ～{0.102^\circ } $、$ 0.2^\circ～{0.202^\circ } $对被检编码器检测静态精度、动态精度的影响，得出了3种不同实验结果。实验结果表明，在检测编码器时，初次安装可控的安装误差在$ 0^\circ～0.102^\circ $范围内可以满足编码器检测技术指标，超过此安装误差的安全范围会导致编码器检测技术指标偏离检测标准。实验结论对提高编码器的检测精度与可靠性有参考价值。 |

| This article addresses the problem that installation errors in the encoder during the detection process result in the generation of installation angular errors. It analyzes the relationship of installation angular errors, rotation angles, and measurement errors. It establishes a model for determining the installation angular errors caused by misalignment in the non-concentric detection system. Through experiments, the impact of three different levels of installation angular errors, namely$ 0^{\circ}\;\mathit{\mathrm{to}}\;0.002^{\circ} $, $ 0.1^{\circ}\;\mathrm{to}\;0.102^{\circ} $, and $ 0.2^{\circ}\;\mathrm{to}\;0.202^{\circ} $, on the static and dynamic accuracy of the detected encoder was analyzed. Three distinct experimental results were obtained. The experimental findings indicate that during encoder detection, initial controllable installation errors within the specified range meet the technical specifications. However, exceeding this safe range of installation errors would cause the deviation of the encoder's detection performance from the standard. The conclusions drawn from the experiments hold importance in enhancing the accuracy and reliability of encoder detection technology. They also provide valuable reference points for future research aimed at improving encoder detection accuracy. |
