At present, several sweepers, trenchless drills and airport baggage cars are used in series orbit motor 。 Cycloidal hydraulic motor of snow sweeper The output shaft of the motor often leaks oil during use, even if the dynamic seal of the output shaft is replaced, it is useless, that is, when the cycloidal motor is used in series, the problem of oil leakage pressure of the casing is ignored.

The oil leakage pressure of the housing refers to the pressure that the motor shaft seal can bear after being fully lubricated inside the motor; If the motor is used improperly, after the machine works continuously for a period of time, Sol hydraulic motor of injection molding machine Due to various factors, the oil in the housing will not be released, which causes the motor housing pressure to become higher and higher, leading to the shaft seal failure first. The casing leakage pressure mentioned here is not the bursting pressure of the casing, but the pressure that the motor output shaft dynamic seal can bear. In the motor samples of some manufacturers, only the back pressure is mentioned. Actually, back pressure refers to the return oil pressure of the motor, not the oil discharge pressure of the casing. During operation, the requirements for the oil discharge pressure of the cycloidal motor housing are as follows.
