説明

In this study's first report, the effects of the dynamic characteristics of a tilt angle supporting element on the operating moment of a swash-plate type variable delivery axial piston pump has been investigated, and a method for predicting the operating moment, that combines a calculation of the dynamic behavior of the tilt angle supporting element and the conventional calculation method for cylinder pressure, has been obtained. <br>The values calculated by this method coincided well with the actual observed experimental values of a pump in which a valve plate with wide, short and deep knotches was used. The calculated and experimental values, however, did not always coincide in the case of the pump in which a valve plate with narrow, long and shallow knotches was used. The authors found that this disagreement was due to an inaccuracy in the calculation of the cylinder pressure. <br>In this report, the efffects of the dynamic characteristics of the tilt angle supporting system on cylinder pressure were investigated. <br>From the re sults, a new method for predicting the cylinder pressure and the operating moment was developed. <br>Both the cylinder pressure and the operating moment calculated by the new method agreed well with the experimental values with no distinction between the valve plate configurations of the pump.
