为使齿轮泵/马达的内泄漏计算及其容积效率评估更加符合实际,依据弹性体的变形规律和轴抗扭能力的一致性要求,提出了随齿顶圆半径线性变动的伺服间隙和伺服轴径,从而构建出相应的内泄漏伺服模型,并分析了齿轮宽径比对容积效率的影响。结果表明,形状系数最大化利于实现容积系数最大化及其轻量化;无根切齿轮的齿顶高系数最大化并不能实现更高的容积效率;宽径比越大,容积效率越高,轻量化效果越好,与固定间隙固定轴径下的结论正好相反。得出内泄漏伺服模型既符合实际又简单可靠的重要结论。
In order to make the internal leakage calculation and volume efficiency evaluation of gear pumps or motors more realistic
based on the deformation law of elastomers and the consistency requirements of the torsion resistance of the shaft
the servo clearance and shaft radius with linear change of addendum radius is proposed
and then a corresponding servo model for calculating inner leakage is derived. Finally
the influence of gear width-diameter ratio on pump volume efficiency is analyzed. All results show that the maximum of gear shape factors is beneficial to the maximum of volume factors and the lightweight of gears; the maximum of addendum coefficients of gears without undercut cannot achieve higher volumetric efficiency; the larger the width-diameter ratio is
the higher the volume efficiency is
and the better the lightweight is
which is opposite to the conclusion under fixed clearance and shaft radius. It is concluded that the servo model for calculating the inner leakage is simple and reliable.
