Abstract: According to the plunger motion characteristics, from the geometric displacement, the structure size, port pair and auxiliary oil ab-sorption of axial piston pump, the different structure types of cylinder and conical cylinder block were researched. Take the axial piston pump which was developed by our company as the calculation and analysis object, the results showed that compared with the cylindrical cyl-inder, conical cylinder block can make geometric displacement increased 1.27mL;cylinder maximum radial size decreased by 0.65%;port pair wear was reduced by 8%;the maximum speed increased by 1.1 times;the auxiliary oil absorption pressure increased by 0.26MPa.
