本文介绍了夹紧比和孔口尺寸对轴向柱塞泵和电机滑靴性能影响的实验和理论研究结果。将运行面抛光成略微凸起的形状对于在所有条件下成功运行似乎是至关重要的。结果表明，在孔口被封闭的情况下，滑靴的运行效果非常令人满意，而且实际上，在这种情况下通常是最稳定的。在欠夹式滑靴中引入孔口增加了间隙。然而，它也会使滑块不稳定，导致滑块对倾斜力偶的影响变得敏感。对过夹紧设计的影响更为复杂，具体取决于夹紧比的精确值和滑块区域的宽度。
The paper presents the results of an experimental and theoretical investigation of the effect of clamping ratio and orifice size on the performance of slippers in axial piston pumps and motors. Polishing of the running face to a slightly convex form appears to be essential for successful operation under all conditions. It is shown that slippers operate perfectly satisfactorily with the orifice blanked and, indeed, are generally most stable in this condition. Introduction of the orifice in under-clamped slippers increases the clearance. However it can also destabilise the slipper resulting in the slipper becoming sensitive to the effect of tilting couples. The effect on overclamped designs is more complex depending on the precise value of clamping ratio and on the width of the slipper land.
