摘要
提出了一种用于求解柱塞泵中滑靴卡盘与球碗之间摩擦功耗的算法。采用将滑靴卡盘与球碗的接触轨迹离散为众多均布的接触点的方法,求解出各个离散点的受力,结合滑靴卡盘和球碗的相对运动计算出二者之间的摩擦功耗,并分析了弹簧力、旋转角速度以及斜盘倾角对摩擦功率的影响。为了验证理论研究的正确性,搭建了滑靴卡盘和球碗的功耗测试试验台,并进行了试验。试验结果表明:滑靴卡盘与球头之间摩擦功耗随着柱塞泵的弹簧力、泵的旋转角速度以及斜盘倾角等参数的增加而增大,当最大斜盘倾角为18°、弹簧力为700N、角速度为3 000r/min时,A4VSO45型柱塞泵中滑靴卡盘与球碗之间的摩擦功耗能够达到240W。
An algorithm for solving friction power loss between the slipper retainer and ball guide in axial piston pump,is proposed.The interface stress is obtained by dispersing the contact path into many uniform contact points,combining with the relative motion analysis,the friction power loss is evaluated.Furthermore,the effects of spring force,angular velocity and angle of swash plate on the friction power loss are discussed.A testing device is constructed to verify the correctness.The experiments demonstrate that the friction power loss between the slipper retainer and ball guide is enlarged with the increasing spring force,angular velocity and angle of swash plate.The friction power in A4VSO45 axial piston pump reaches to 240 W when the spring force is 700 N,angular velocity is 3 000 r/min and angle of swash plate is 18°.
