Cycloid hydraulic motor Due to the large amount of daily labor, oil leakage is inevitable, because in the daily application of the motor, the oil seal and the output shaft are constantly rubbing, resulting in the loss of the actual sealing effect of the oil seal. In case of oil leakage, the oil seal must be removed and replaced. So cycloid Hydraulic motor How to replace the oil seal?

Oil seal replacement process:

During installation, if the outer surface of the journal has low roughness or 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 matching part of oil seal lip or journal. Apply sealant on the outside of the oil seal, and wrap the key groove position on the shaft with a hard paper shell to prevent scratching the oil seal lip. Use common tools to turn the oil seal inward and insert it. Do not hit or punch the oil seal hard to prevent the oil seal from deforming or breaking and becoming invalid; In case of lip inversion, yellowing falling off and oil seal tilting, try to remove it and install it again. It should be noted that when the shaft diameter is not worn and the oil seal spring has sufficient elasticity, it is not necessary to shrink the inner yellowing privately.

Above is the process of removing and replacing the oil seal of the cycloidal hydraulic motor. We hope that you will frequently check the damage of the journal and rolling bearing and the embrittlement of the oil seal vulcanized rubber in the whole process of applying the motor to prevent the hydraulic motor from entering the post with "disease".

The repair of the inner bevel stator and plunger pump is derived from the high pressure oil of the hydraulic oil pump, which is distributed to the axial piston rod on the engine block (motor rotor) through the oil inlet of the stator oil distribution shaft. The other end of the piston rod is connected to the roller, and the roller clings to the inner bevel stator with axial force travel arrangement by means of back pressure. The piston rod is at the bottom dead center. When the roller contacts the high point of the inner slope of the stator, the piston rod is at the bottom dead center
