Cycloid hydraulic motor As a daily hydraulic power system, it is widely used in many areas today. If long-term application is unavoidable, oil leakage will occur Hydraulic motor Oil leakage situation, we find the key cause

(1) Motor gap oil leakage: High torque of hydraulic motor If the "O" ring located between the motor housing and the front diaphragm, or between the front diaphragm and the motor stator body, or between the motor stator body and the rear diaphragm is brittle or crushed, it is only necessary to replace the "O" ring. If the model and specification of the rubber ring are not clear, the manufacturer can be consulted. This is how to deal with the oil leakage of the cycloidal hydraulic motor.

(2) Oil leakage at the seal: the O-ring under the seal is crushed or embrittled, losing the actual sealing effect. The probability of this happening is very low. If so, only replace the O-ring.

(3) Bearing end cover oil leakage: because the oil seal and output shaft are in constant friction during the daily application of the motor, the oil seal and shaft surface will be damaged. If it exceeds a certain extent, the oil seal will lose its sealing effect, causing oil leakage. Solution: When disassembling and assembling the motor cover, it is necessary to remove and replace the oil seal. If the output shaft is seriously damaged, it is necessary to remove and replace the output shaft at the same time. If the output shaft is not seriously damaged, it is necessary to pay attention not to take the output shaft out when disassembling the front cover of the motor, otherwise it is possible to change the oil distribution relationship of the motor when installing it, and then change the rotation of the motor.
