1. The operation of the motor is weak:
A, check whether the pairing of the stator and the rotor is too loose, because the internal parts of the motor are in a state of friction with each other in operation, if the liquid.
If the hydraulic oil in the pressure system is too poor, it will accelerate the wear of the internal parts of the motor. When the pin teeth in the stator exceed a certain limit, it will be ordered.
The internal gap between the daughter pairs becomes larger, which can not achieve the normal oil sealing effect, which may cause further internal leakage problems, which is characterized by the motor in the.
The operation is normal under no load, but the sound is louder than normal, and the operation will be weak or slow under load. The solution is to change the outer diameter slightly.
Big pin teeth.
B. Check whether the accelerated internal leakage between the output shaft and the shell hole is due to wear. The main reason for the failure is that the hydraulic oil is not pure enough, including.
Certain impurities cause grooves inside the shell, and the increase of internal leakage makes the motor powerless. The solution is to replace the shell or the whole weight in time.
New match.
2. when the rotational speed is reduced, the output torque is reduced.
A, there is no clearance compensation mechanism for cycloidal motor (except plane distribution), the rotor and stator are sealed by linear contact, and the.
If the sealing line is long, if the contact surface between the rotor and the stator is damaged due to poor tooth profile accuracy, poor assembly quality or pull at the contact line, the internal leakage will be larger.
The volume efficiency decreases, the rotational speed decreases and the output torque decreases. The solution is to choose the needle wheel stator, consider replacing the needle wheel, and.
Match with rotor.
B, the meshing position of the rotor and the stator, and the distribution position of the distribution shaft and the body, the consistency of the relative position of the two to the output torque.
It has a great influence, if the corresponding relationship between the two is mismatched, it means that the accuracy of flow distribution is not high, which will further lead to the increase of torsion speed and output torque.
The solution is to determine the specific location of these parts and adjust them accordingly.
C, distribution shaft wear-large internal leakage, which affects the accuracy of oil distribution, or due to the large fit gap between the distribution sleeve and the shell hole of the motor body.
The accuracy of oil distribution may reduce the volumetric efficiency and affect the speed and output torque of the motor. The solution is to use electroplating or brush plating.
Repair to ensure that the gap is as appropriate as possible. These are some maintenance knowledge of servo motor maintenance.
