The cycloid hydraulic press motor is a medium and small sized, low-speed, large torque hydraulic press motor with internal cycloid gears. It has simple structure, good low-speed gear characteristics and strong overweight working capacity in a short time orbit motor There is a motor stator and a theme movable blade inside. The motor stator, blade and rotating shaft divide the motor into two cavities. Each cavity has an oil hole. When one oil hole is filled with liquid, the other is filled with oil, which promotes the blade to shake.

At present, several system software of cycloidal motor serial application are used on sweeping car, trenchless drill and airport baggage car. In the whole process of application, the motor output shaft often leaks oil. Even if the dynamic seal of the output shaft is replaced, it will not help. That is to say, when selecting cycloidal motors and using them in series, we ignored Plate port cycloidal motor Difficult problem of working pressure of case oil leakage.

Generally speaking, the working pressure of casing oil discharge of Chinese axial flow motor is lower than 3.0 MPa, and that of disc flow motor is lower than 5.0 MPa. However, the casing oil discharge working pressure of the axial flow motor produced by our company is 7.0-10.0 MPa, and that of the disc flow motor is 7.0 MPa. This data information has been confirmed on the motor template of the enterprise. It must be noted that when the working pressure of the motor case oil leakage (internal leakage) exceeds its optimal value, the motor case leakage port must be connected to the car oil tank, otherwise it will greatly endanger the service life of the motor shaft sealing, or even make the shaft sealing invalid, resulting in oil leakage at the output shaft.
