Today's low-speed high-torque hydraulic motors are mainly used in various machinery manufacturing industries, such as shipbuilding, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, petrochemical, port machinery and other machinery industries, then low-speed high-torque hydraulic motors. What kind of mechanical equipment is it? What characteristics does it make everyone like it? China hydraulic motor analysis of the reasons:


Low-speed high-torque hydraulic motors have been used earlier, and are known as Starwell hydraulic motors. China's similar model is JMZ type, its rated pressure is 16MPa, the highest pressure is 21MPa, and the theoretical displacement is up to 6.140r/min. The motor of the low-speed high-torque hydraulic motor is composed of a casing, a crank-link-piston assembly, an eccentric shaft and a distribution shaft, and five cylinders are radially arranged uniformly in the circumference of the casing to form a star-shaped casing; There is a piston, the piston and the connecting rod are connected by a ball joint, and the big end of the connecting rod is made into a saddle-shaped cylindrical tile surface which is closely attached to the eccentric circle of the crankshaft, and its center is the eccentric moment of the center of the crankshaft and the distribution shaft of the hydraulic motor. The crankshaft is coupled with the cross key and rotates with the crankshaft. The pressure oil of the motor passes through the distribution shaft passage and is distributed by the distribution shaft to the corresponding piston cylinder.


Since the orientation of the distribution shaft transition seal interval is consistent with the eccentric direction of the crankshaft and rotates at the same time, the oil inlet window of the distribution journal always faces two or three cylinders on one side of the eccentric line, and the oil suction window faces the other side of the eccentric line The remaining output cylinders, the total output torque is the superposition of the torque generated by all the plungers on the center of the crankshaft, which allows the rotary motion to continue.


Driven by the years of reform and opening up, China's comprehensive national strength has been greatly improved. These advances cannot be separated from the wisdom of generations of workers, and at the same time, they are inseparable from those products and equipment that struggle in the first line, as the machinery industry. The big assistant, the low-speed high-torque hydraulic motor, is playing its role in escorting the development of the machinery industry.
