A hydraulic motor is used to refer to an energy conversion device that outputs rotary motion and converts the hydraulic energy provided by the hydraulic pump into mechanical energy. The low-speed and high-torque hydraulic motor refers to a hydraulic motor with a relatively low speed but a relatively large output torque. It is mainly used in injection molding machinery, ships, hoists, construction machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, and marine machinery. , petrochemical, port machinery, etc.

The low-speed and high-torque hydraulic motor consists of a casing, a crank-rod-piston assembly, an eccentric shaft and an oil distribution shaft. Five cylinders are evenly arranged radially and evenly around the circumference of the casing to form a star-shaped casing; the cylinder is equipped with a piston , the piston and the connecting rod are connected by ball twist, the big end of the connecting rod is made into a saddle-shaped cylindrical surface, which is closely attached to the eccentric circle of the crankshaft, the eccentric moment between it and the rotation center of the crankshaft, the distribution shaft of the hydraulic motor and the crankshaft are connected by a cross key Together, rotating with the crankshaft, the pressure oil of the motor passes through the distribution shaft channel, and is distributed by the distribution shaft to the corresponding piston cylinder, the fourth and fifth chambers of the cylinder are connected to the pressure oil, and the piston is subjected to the action of the pressure oil; in the remaining piston cylinders , the oil cylinder is in an excessive state, and the oil cylinders 2 and 3 are connected to the oil discharge window; according to the movement principle of the crank connecting rod mechanism, the plunger affected by the oil pressure acts a force on the center of the eccentric circle through continuous rushing, pushing the crankshaft around The rotation center rotates to output speed and torque to the outside.

If the oil inlet and outlet ports are swapped, the hydraulic motor will also rotate in the opposite direction. With the rotation of the drive shaft and the distribution shaft, the distribution state changes alternately. During the rotation of the crankshaft, the volume of the oil cylinder on the high-pressure side gradually increases, while the volume of the oil cylinder on the low-pressure side gradually decreases. Therefore, during operation, the high-pressure oil continuously enters the hydraulic motor, and then is continuously discharged from the low-pressure chamber.

In short, because the orientation of the transition seal interval of the distribution shaft 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 the two or three cylinders on one side of the eccentric line, and the oil suction window faces the eccentric line. For the remaining cylinders on the other side, the total output torque is the superposition of the torque generated by all the plungers to the center of the crankshaft, which allows the rotary motion to continue .
