The oil distribution sleeve is synchronized with the rotor, so that the rotor rotates once, and the seven oil distribution holes on the housing are closed 840 times by the twelve diaphragms of the oil distribution sleeve, while the rotor and stator form the largest and smallest closed cavities respectively 1420 times, collectively referred to as the seal cavity. In the circle of the oil distribution hole of the closed housing, the oil inlet and outlet of the rotor have three chambers respectively, one Henan High speed high torque cycloidal hydraulic motor The cavity is closed. When the rotor is transferred from the smallest enclosed cavity to the next largest enclosed cavity, before the rotor is transferred from the largest enclosed cavity to the next smallest enclosed cavity, oil is supplied to four cavities and three cavities customized High speed high torque cycloidal hydraulic motor Drain the oil.

The radial piston hydraulic motor uses a cam ring with a special curve to make each plunger reciprocate several times within one cycle of cylinder block rotation, which is called multi action customized High speed high torque cycloidal hydraulic motor Internal curve radial plunger hydraulic motor (referred to as internal curve motor) is used. The internal curve motor has the advantages of small size, light weight, radial force balance, small torque ripple, high starting efficiency, stable operation at very low speed, etc. It has been widely used High speed high torque cycloidal hydraulic motor Price In marine machinery. Working principle of inner curve motor: the inner wall of the cam ring (housing) is composed of x evenly distributed curved surfaces with the same shape. Each curved surface with the same shape can be divided into two symmetrical sides. The side that allows the plunger set to extend outward is the working section (oil inlet section), and the opposite side is called the oil return section. The number of reciprocating times of each plunger per revolution of the hydraulic motor is equal to the number of curved surfaces of the cam ring x (x is called the number of times of action of the motor).

As the power source and actuator of the hydraulic system, the performance of the hydraulic motor has a great impact on the performance of the entire hydraulic system. Therefore, the importance of studying the hydraulic motor performance test system is customized High speed high torque cycloidal hydraulic motor It is very important that the rise and application of hydraulic testing technology based on virtual instrument has opened up a broad prospect for the performance testing of hydraulic motors. Hydraulic motors are widely used in machine tools, metallurgy, engineering machinery, plastic machinery, agricultural machinery, mining machinery, marine machinery and many other important fields. The performance of the hydraulic motor has a decisive impact on the whole system, and will directly affect the stability of the system. At the same time, the performance of the hydraulic motor will have an impact on the life of the system components and the production efficiency of the system. Henan Price Unexpected failure of hydraulic motor will greatly reduce production efficiency.

Cycloidal hydraulic motor structure: the internal meshing gear pair consisting of rotor and stator, cycloidal needle wheel, as the meshing pair, has a torque generating part. The stator, together with the spacer and the rear cover, is fixed on the housing to form seven cavities that are only connected with the oil holes on the housing one by one. A distribution mechanism consisting of an oil distribution sleeve and a housing. Two oil distribution sleeves Henan High speed high torque cycloidal hydraulic motor The ring groove is respectively connected with the oil inlet and return ports of the housing, and its longitudinal groove has twelve oil ports, High speed high torque cycloidal hydraulic motor Price Six oil ports and the oil distribution hole of the housing form the oil distribution link. The splines at both ends of the linkage shaft are respectively connected with the rotor and the output shaft, which is used to transmit torque and ensure that the oil sleeve is synchronized with the output shaft. The function of the output shaft is to output the torque generated by the rotor through the linkage shaft and drive the oil distribution device to rotate synchronously.
