Abstract

Cylinder block is driven by tapered piston for bent-axis type piston pump, so that geometrical mechanism is very complicate. Piston rod must have not separated from shaft when shaft and piston rod is assembled. For this reason, shaft design is changed. Finite element analysis is performed for analyzed structural stability and flexible dynamic behavior. The result of the analysis, maximum equivalent stress occurred under yield stress, therefore structural stability is satisfactory. and flexible dynamic analysis give useful information about driving gear. These background data is avail of manufacture of piston pump.
