减速装置的曲轴连杆式液压马达的毕业设计说明书 摘 要 曲轴连杆式液压马达的特点是可靠性好、效率高、寿命长、噪音低转速范围宽等一系列特点因而适用范围广，可广泛应用于建筑工程机械、起重运输设备、重型冶金机械、石油煤矿机械、船舶甲板机械、机床、塑料、地质钻探设备等各种机械的液压传动系统中。特别适用于提升绞盘、卷筒驱动、各种回转机械驱动、履带和轮子行走机构的驱动等传动机械中。液压马达作连续回转运动并输出转矩的液压执行元件。Crankshaft connecting rod hydraulic motor is characterized by high reliability, high efficiency, long life, low noise, wide speed range and a series of characteristics, and thus for a wide range, can be widely used in construction machinery, lifting and transport equipment, heavy metallurgical machinery , oil mining machinery, marine deck machinery, machine tools, plastics, geological drilling equipment and other machinery, hydraulic transmission systems. Especially suitable for hoisting winch, drum drive, a variety of rotary mechanical drive, crawler and wheel drive running gear and other transmission machinery. Crankshaft connecting rod hydraulic motor has compact structure, flexible layout, light weight, small moment of inertia, speed performance, low-speed, smooth operation, high efficiency starts, acceleration and braking time is short, overload protection easy. Etc., which included access to a wide range of applications. Extensive use of domestic and in some ton freighters, plow, tractor, excavator oil drilling machines and other machines for a trial. 20 In the early 1960s, began on low speed high torque hydraulic motor foreign prototype for mapping imitation, initially forming a crank rod motor JDM Series, the rated working pressure of 16MPa hydraulic motor according to the structure type of gear can be divided into , vane, piston, and other types. Crank motor principle is pressure oil through the oil pan into the cylinder, forcing the plunger protrudes from the cylinder and slide along the swash plate, the cylinder rotates together with the shaft work is done, back to the oil through the oil pan The other opening of the discharge. Gear motors and vane motors are high-speed motor, the output torque of inertia and are very small, easy startin
