| description | 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. |
