The MS18 hydraulic motor is an inner curve multi-acting radial piston motor. Its core components include the stator, rotor, plunger roller pair and fluid distribution. The inner curve is composed of several curve segments of the same shape, and each curve segment is further divided into an ascending section, a transitional section and a descending section. When the plunger moves to the bottom and connects to the upward section of the high-pressure oil, the hydraulic pressure acting on the plunger generates a normal force at the contact point between the roller and the stator curve. This force can be divided into tangential force and radial force. Among them, the tangential force is transmitted to the cylinder through the roller and the plunger, causing the cylinder to generate a torque to rotate around the motor axis, driving the cylinder to rotate until the roller enters the transition section. When the roller passes through the transition section of the curve and enters the descent section, it descends along the stator curve. The bottom of the plunger is connected to the return oil chamber, and the hydraulic oil is discharged back to the return oil chamber. This cycle repeats itself, achieving the conversion of hydraulic energy to mechanical energy.
3. Product Features and Advantages:
Modular design: The overall structure is designed in a modular way, which can be combined according to user or system requirements, facilitating optimization and matching with various hosts.
High efficiency: It adopts multi-acting planar flow distribution technology, which is less sensitive to pressure and temperature, and can automatically compensate for the wear between the flow distribution friction pairs, ensuring the motor’s high volumetric efficiency for a long time. Meanwhile, the roller and plunger structures have simple force transmission and few friction pairs, which improves mechanical efficiency.
High working pressure and excellent low-speed performance: The maximum pressure can reach 31.5MPa. Due to the small inertia of the force transmission mechanism and the sealing of the plunger pair by the plunger ring, the starting efficiency is high and the low-speed stability is good.
It can withstand radial and axial loads: By adopting an independently set mechanical output device, the diameter dimensions of the bearings and output shafts are relatively large, and the hydraulic function device has a balanced radial force, providing pure torque output. Therefore, the motor can withstand considerable axial and radial forces.
Diversified output methods: There are multiple output shaft selection forms and torque module configurations, such as wheel flange shaft output, shaft structure output form, dual output through shaft body structure, etc.
4. Usage functions and purposes:
Function of use: Convert the liquid pressure energy provided by the hydraulic pump into mechanical energy of its output shaft, providing torque and rotational speed for the hydraulic system to drive the hydraulic actuator to work.
Application: Widely used in situations that require low-speed and high-torque drive.
5. Applicable machines and scenarios:
It is applicable to construction machinery, building machinery, mining machinery, lifting and transportation equipment, heavy metallurgical machinery, geological drilling and other equipment. It is particularly suitable for the drive of crawler and wheel traveling mechanisms, as well as various winches, hydraulic rotary devices, etc.
6. Similar models:
Other models in POCLAIN’s MS18 series, such as the MS18-0, etc. In addition, there is the MSE18 series radial high-torque wheel motor, which shares certain similarities with the MS18 series in structure and performance.

7. Precautions for Use
Pre-operation inspection: Ensure that all components of the hydraulic system are correctly connected to avoid malfunctions or leaks caused by incorrect connections. Add oil to the specified height through the filter to ensure that the hydraulic system has sufficient hydraulic oil. Start and run under no-load conditions for 10 to 15 minutes, and exhaust until the system stabilizes.
During operation, pay attention to: Gradually increase the load and observe whether there are any abnormal phenomena, such as noise, oil temperature rise and oil leakage, etc. Always keep an eye on its operating condition, including sound, temperature and vibration, etc. If any abnormality is detected, stop the machine immediately for inspection.
Maintenance and care: Regularly change the hydraulic oil. Generally speaking, the oil should be changed once after the motor has been running for 50 hours, and then replaced according to the maintenance rules. Regularly clean the exterior and interior of the motor to remove dust, oil stains and other contaminants. Regularly inspect the seals and bearings of the motor. If there is any wear or damage, replace them in time. Regularly check the lubrication condition of the bearings and add or replace the lubricant in time.
Others: Select the appropriate hydraulic oil, taking into account its performance indicators such as viscosity, cleanliness and stability; Avoid overloading the motor. Ensure that the motor is installed in a stable and firm position, and that the inlet and return oil pipes are connected correctly and firmly.
