Due to the large amount of daily labor, the cycloidal hydraulic motor is inevitably subject to oil leakage. Because the oil seal and output shaft are constantly rubbed in daily application of the motor, resulting in the loss of sealing effect of the oil seal. In case of oil leakage, the oil seal must be removed and replaced. How to replace the oil seal of the cycloidal hydraulic motor?

Oil seal replacement process:

During assembly, if the outer surface roughness of the shaft diameter is low or has defects such as rust, rust, burr, etc., it shall be polished and polished with fine sand cloth or grindstone; Apply cleaning engine oil or grease on the oil seal lip or the matching part of the shaft diameter. Apply sealant on the outer side of the oil seal, and wrap the pin hole position on the shaft with cardboard to prevent scratching the oil seal lip. Use common tools to turn the oil seal inward and insert it. Do not smash or punch it hard to prevent the oil seal from deforming or breaking the spring and becoming invalid; If the lip is reversed, the spring falls off and the oil seal is tilted, try to remove it and reinstall it. Pay special attention to that when the shaft diameter is not worn and the oil seal spring has sufficient elasticity, it is not necessary to shrink the inner spring without permission.

The above is the process of removing and replacing the oil seal of the cycloidal hydraulic motor. We look forward to checking the shaft diameter, the damage of the rolling bearing and the aging of the oil seal plastic frequently during the application of the motor to prevent the oil motor from entering the post with "disease".
