The effect of oil distribution accuracy on the efficiency of cycloidal hydraulic motor can be compared to the effect of ignition time on the power of internal combustion engine. It can be seen from the working principle of cycloidal hydraulic motor that the oil distribution sleeve and the rotor rotate synchronously. The so-called oil distribution accuracy is the accuracy of the oil distribution link cooperating with the rotor to rotate oil inlet, sealing and oil discharge.
There are many factors that affect the oil distribution accuracy, such as the asymmetry between the rotor spline and the cycloidal tooth shape, the position accuracy of the stator trowel tooth hole relative to its bolt hole, the asymmetry of the pin hole on the output shaft relative to its internal spline, the equal division accuracy of the longitudinal oil groove on the oil sleeve and the position accuracy relative to the wedge groove, the asymmetry of the spline at both ends of the linkage shaft. As long as these factors are controlled within the tolerance range, the impact on the oil distribution accuracy will not be very large, because all the processing errors will not be biased to one side.
What has the greatest influence on the oil distribution accuracy is the matching gap between the splines at both ends, followed by the position accuracy of the oil distribution hole of the shell relative to the screw hole used for installing the stator, which is difficult to be guaranteed technically, and the position accuracy of the oil distribution hole relative to the shell when the stator is fixed on the shell. The cycloidal pinwheel meshing pair is used as the power component of the motor, the rotor is the active part, and the output shaft and the oil distribution sleeve connected with the pin are the passive part. Due to the spline gap, the output shaft and the oil distribution sleeve lag behind the rotor at an Angle, so the oil distribution sleeve deviates from the correct position.
