摘要
为确定圆柱齿轮流量计结构参数和流体介质物理特性对其性能影响的规律,确定最佳装配间隙,提出了基于6自由度运动模型的仿真方法,基于该方法分别研究了不同装配间隙和不同流体粘度对DN16圆柱齿轮流量计性能的影响。研究结果表明:随着装配间隙的减小,线性度误差逐渐减小。当齿顶圆间隙为140μm、齿轮端面间隙为100μm时,线性度误差达到最优值0.13%;线性度误差随着流体粘度的增大而减小,当粘度为42.7 mm^(2)/s时,线性度误差仅为0.03%。
To determine the influence of the structural parameters of the cylindrical gear flowmeter and the physical characteristics of the fluid medium on its performance,and to determine the optimal assembly clearance,a simulation method based on the six-degree-of-freedom motion model is proposed.Based on this method,the effects of different assembly clearances and different fluid viscosities on the performance of the DN16 cylindrical gear flowmeter are studied.The results show that the linearity error gradually decreases with the decrease of the assembly clearance.When the tip clearance is 140μm and the gear end clearance is 100μm,the linearity error reaches the optimal value of 0.13%.The linearity error decreases with the increase of fluid viscosity.When the viscosity is 42.7 mm^(2)/s,the linearity error is only 0.03%.
