一、引言对于轴向柱塞泵(或轴向柱塞马达),无论是斜盘式的,还是斜轴式的,配油面(即旋转的缸体与静止的配油盘之间的接触面)的平衡都是一个重要问题。如果配油面上压紧力过大,会产生严重的磨损甚至研烧;如果配油面上压紧力太小,又会产生严重的泄漏,使泵(或马达)的容积效率降低。因此,对配油面上压紧力与推开力的平衡问题,必须认真地进行计算。但是,现在流行的计算方法种类繁多,计算结果互不一致,实际使用时感到难以抉择,无所适从。而且,由于不同方法算出的剩余压紧力不同,由此推算出来的配油面比压也大不 I. INTRODUCTION For axial piston pump (or axial piston motor), either swash plate type or bevel type, the oil level (ie the contact between rotating cylinder and stationary oil pan The balance of the face is an important issue. If the oil pressure on the surface is too large, it will have serious wear and tear even burning; if the oil pressure is too small, there will be a serious leak, the pump (or motor) to reduce the volumetric efficiency. Therefore, the balance of the pressing force and pushing force on the oil level must be carefully calculated. However, a wide range of popular calculation methods, the results of each inconsistent calculation, the actual use of hard to decide, know what to do. Moreover, due to the different methods of calculating the residual pressure difference, which deduced from the pressure with the oil pressure is also large
