The radial runout of tooth ring of the coniflex gear, which is an important test item, is an important factor influencing the accumulated error of tooth spacing and the error of tooth spacing. 直齿锥齿轮的齿圈径向跳动是重要的检验项目,是影响齿距累积误差和齿距误差的重要因素。
This paper introduces several cases of the radial runout of tooth ring, and probes into the influencing factors on and regulating methods for the accumulated error of tooth spacing and the error of tooth spacing. 介绍了齿圈径向跳动出现的几种情况,探讨了齿距累积误差以及齿距误差的影响因素及调整方法。
An analytical expression to calculate the conducting strip interdigital capacitance with strip width and spacing being unequal on a dielectric substrate is derived by the method of conformal transformation. Its error is estimated within 1.7% which is reasonable for application. 本文运用保角变换法,简捷地导出了计算介质片上的指线宽度与指线间隔不相等的金属条带交指型电容的解析表示式,误差在1.7%以内,符合实用的要求。
The results show that the difference of the numerical results with same grid numbers and different grid spacing is relatively big. Moreover, the error of numeral results is big, if the chose of grid spacing is unsuitable. 数值结果表明,相同网格数、不同网格间距下数值结果的差别相对较大,若网格间距选取不当,将给数值结果带来较大误差。
The predicted fracture stress matrix cracking stress and crack spacing just have error less than 20% with the corresponding experimental value. 预测的断裂应力、基体开裂应力和裂纹间距与实测值最大误差在20%以内。
