Product details
The "A2FE180 Inclined Axis Quantitative Piston Hydraulic Motor" is a specific type of hydraulic power component. Below is a detailed introduction covering its basic concept, structural features, working principle, performance parameters, and application scenarios:
Basic Concept
The inclined-axis quantitative piston hydraulic motor is an actuator in the hydraulic transmission system, capable of converting hydraulic energy into mechanical energy to provide rotational power for various mechanical equipment. "A2FE180" is the model number of this hydraulic motor, where different combinations of letters and numbers represent specific parameters and characteristics of the motor, such as displacement and installation method. "Inclined Axis" indicates its inclined-axis structure. "Quantitative" means it is of the quantitative type, that is, the output flow is proportional to the input flow, and the displacement is fixed. "Piston Hydraulic Motor" clearly identifies its type as a piston hydraulic motor.
Structural Features
• Inclined-axis Design: Unlike the swashplate hydraulic motor, the axis of the main shaft in an inclined-axis motor forms a certain angle with the axis of the piston cylinder block. This design makes the motion trajectory of the pistons in the cylinder block an oblique line. During rotation, there is relative sliding between the bottom of the pistons and the return plate, but the friction between the pistons and the cylinder bore is relatively small, which is beneficial for improving the motor's efficiency and lifespan.
• Quantitative Structure: The displacement of this motor is fixed, which means that under a certain input flow, its output speed is relatively stable. This characteristic gives it an advantage in applications that require precise speed control.
• Piston Assembly: It typically consists of components such as pistons, piston sleeves, and slipper shoes. The pistons move back and forth in the cylinder bore. Through contact between the slipper shoes and the return plate (or related structures of the return plate in the inclined-axis type), force transmission and motion conversion are achieved.
Working Principle
• Hydraulic Oil Inlet: High-pressure hydraulic oil enters the cylinder block through the motor's oil inlet, pushing the pistons outward.
• Force Transmission and Rotation: Due to the inclined axis, as the pistons extend outward, they generate a tangential component of force on the cylinder block. This force causes the cylinder block to rotate around the axis of the main shaft. As the cylinder block rotates, different pistons sequentially enter the oil suction and oil discharge processes.
• Hydraulic Oil Outlet: After completing the work, the low-pressure hydraulic oil is discharged from the motor's oil outlet and returns to the oil tank of the hydraulic system, completing one working cycle. By continuously inputting high-pressure hydraulic oil, the motor can continuously output rotational power.
Performance Parameters
• Displacement: The "180" in A2FE180 is usually related to the displacement, and the unit may be milliliters per revolution (ml/r), indicating the volume of hydraulic oil discharged by the motor per revolution. The larger the displacement, the greater the output torque of the motor under the same input flow.
• Rated Pressure and Maximum Pressure: The rated pressure refers to the pressure that the motor can withstand for a long time under normal working conditions. The maximum pressure is the limit pressure that the motor can withstand for a short period. These two parameters reflect the pressure-bearing capacity of the motor.
• Speed Range: It includes the minimum stable speed and the maximum speed. The minimum stable speed determines the smoothness of the motor during low-speed operation. The maximum speed limits the upper application limit of the motor.
• Torque Characteristics: The output torque is proportional to the input pressure and displacement. Under the rated pressure, the motor can output a certain rated torque to meet the needs of different loads.
Application Scenarios
• Construction Machinery: Such as excavators, loaders, and cranes. In these equipment, hydraulic motors are used to drive the slewing mechanism, traveling mechanism, etc., enabling the rotation and movement of the equipment.
• Agricultural Machinery: For example, combine harvesters and tractors. Hydraulic motors can drive the harvesting devices and transmission systems, improving agricultural production efficiency.
• Industrial Equipment: In injection molding machines and die-casting machines, hydraulic motors are used to drive the opening and closing of molds, ejection, and other actions, ensuring the normal operation of the equipment.
• Marine and Ocean Engineering: They can be used in the steering gears and deck machinery of ships, providing power for ship maneuvering and operations.
