本文导出了直轴自位式缸体结构的轴向柱塞泵油压力对缸体的瞬时作用力和力矩的解析表达式,得出了一些主要的设计参数和有指导意义的结论。文中算式对其它类型的轴向柱塞泵亦有应用价值。 In this paper, the analytical expression of the instantaneous force and moment of the axial piston pump with axial piston pump with straight shaft self-aligning cylinder structure is deduced. Some main design parameters and some conclusions are given. The formulas in the paper also have application value to other types of axial piston pumps.
