| 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 140 μm、齿轮端面间隙为 100 μm 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-offreedom 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 140 μm and the gear end clearance is 100 μm, 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%. |
