    Design structure of DMS18 Internal Curve Hydraulic Motor

    DMS18 inner curve hydraulic motor adopts inner curve design. This layout makes the motor structure more compact, smaller and lighter. The inner curve design optimizes the flow path of hydraulic oil, reduces energy loss and improves transmission efficiency. DMS18 also adopts modular design concept, independently designs each functional component of the motor, which is convenient for maintenance and replacement, and improves the reliability and maintainability of the whole machine.

    The cylinder of DMS18 is the main component of the hydraulic motor, carrying various moving parts and providing working space for hydraulic oil. The cylinder is designed with precise arc grooves, which cooperate with the throttle holes on the distribution plate to realize the suction, compression and discharge of hydraulic oil. The design of the distribution plate is particularly critical, which determines the flow direction and flow size of the hydraulic oil and has a direct impact on the performance of the motor. The distribution plate of DMS18 is made of high-strength and high-wear-resistant materials, and is precisely processed and heat-treated to ensure its long-term stable operation. The piston of the DMS18 motor is the main component for transmitting hydraulic pressure. It reciprocates along the arc groove inside the cylinder to convert hydraulic energy into mechanical energy. The design of the piston fully considers the sealing and movement stability of the hydraulic oil, and adopts a special sealing structure and wear-resistant materials. The connecting rod connects the piston and the output shaft, converting the reciprocating motion of the piston into the rotational motion of the output shaft. The connecting rod design of DMS18 takes into account multiple factors such as strength, stiffness, and weight to ensure the accuracy and reliability of torque transmission. The output shaft of DMS18 is the power output component of the motor, carrying the rotational motion of each moving part and transmitting the torque to the external load. The design of the output shaft takes into account multiple factors such as stiffness, strength, and wear resistance. It is made of high-strength alloy materials and is precision machined and heat treated. The bearing supports the output shaft to reduce friction and wear during its movement. DMS18 uses high-quality bearings and lubrication systems to ensure the long-term stable operation of the output shaft.

    Sealing and lubrication are important links that cannot be ignored in the design of hydraulic motors. The DMS18 internal curve hydraulic motor adopts advanced sealing structures and lubrication systems to ensure the sealing of hydraulic oil and lubrication of moving parts. The design of the sealing structure fully considers multiple factors such as the pressure, temperature, and speed of the hydraulic oil, and adopts high-performance sealing materials and structural forms to ensure zero leakage and efficient transmission of the hydraulic oil. The lubrication system reduces the friction and wear between the moving parts by regularly supplying lubricating oil or hydraulic oil to the moving parts, thereby improving the reliability and service life of the motor. The hydraulic motor will generate a lot of heat during operation. If the heat is not dissipated in time, the motor temperature will rise, the performance will decrease, and it may even be damaged. The DMS18 inner curve hydraulic motor adopts an efficient cooling and heat dissipation system. By optimizing the heat dissipation structure and increasing the cooling area, the operating temperature of the motor can be effectively reduced. The DMS18 inner curve hydraulic motor also adopts an intelligent temperature monitoring and alarm system, which can monitor the temperature status of the motor in real time and send out an alarm signal when necessary to remind the user to deal with it in time.
