本论文阐述了液压马达的工作原理，合理选择了马达排量、柱塞直径和偏心距等参数。计算了七星轮最小内切圆半径、马达的最小外径。对马达的运动学进行了分析。设计了柱塞内弹簧，并验算了它的稳定性、疲劳强度及共振。32652
配流盘处的联接螺钉受到了三个力的作用，比较危险，利用螺钉即被连接件的受力和变形理论，对它进行了选择计算。
马达的泄露包括三部分：柱塞底部小孔处的泄露、柱塞与缸之间的泄露和配流盘处的泄露，本文对以上各种情况下的泄漏量公式进行了详细推导，分析了马达正反转各柱塞的进液条件，用计算机求解总泄漏量随曲轴转角的变化。
马达的排量、压力、转速和扭矩都随曲轴转角发生变化，本论文对各量的变化规律及极值点和脉动率进行了理论分析，计算机求解得到的结果与理论分析相同。

The design and calculation of high water-based double radial piston hydraulic motor
[Abstract] To solve the winch explosion problem fundamentally, so we use the service within the high-pressure emulsion pump station Face liter column for power, driving the hydraulic motor.
This paper describes the working principle of the hydraulic motor, a reasonable choice of the motor displacement, the plunger diameter and eccentricity and other parameters. Seven rounds calculate the minimum radius of the inscribed circle, the motor minimum outer diameter. Motor kinematics were analyzed. Design of the inner plunger spring, and checking its stability, fatigue strength and resonance.
Coupling screw at the valve plate by the action of the three forces, more dangerous, force and deformation theory namely use screw joint, it was calculated choice.
Motor leakage consists of three parts: the hole at the bottom of the plunger leak, leakage and leakage at the valve plate between the plunger and the cylinder, the paper leakage above formula in each case a detailed derivation analysis of the motor reversing the plungers into the liquid condition, with the computer to solve the total leakage variation with crank angle.
Motor displacement, pressure, speed and torque are changed with the crank angle, the thesis of the amount of each variation and extreme points and pulsation rate theoretical analysis, the results obtained with the theoretical computer to solve the same analysis.
