Oil was leaking from the geared motor, so the motor and other parts were serviced. The inside of the gear reducer is a planetary gear mechanism, which is directly connected to the motor output shaft by a hollow shaft to transmit driving force to the gear reducer without loss. Consumable parts were replaced and the shaft was repaired.
Separate from motor and disassemble
Condition at time of delivery. Paint looks quite damaged due to years of use.
Disassembling the planetary gear reducer by disconnecting the electric motor.
The spindle is being taken out.
The lip side of the seal does not appear to be damaged.
Planetary Reduction Gear Reduction Gear Parts Status
There seems to be no particular abnormality in the gear section.
The lip side of the seal does not appear to be damaged.
Planetary reduction gear parts repair
Observing the mating part of the output shaft, lip marks of the oil seal can be seen.
We repaired the lip mark while paying attention to the role of the machine and the elements of the components.
Lip marks of the oil seal can also be seen on the hollow shaft.
The lip marks were repaired by considering the repair method, material, etc., in the same way as the output shaft.
Assembly and commissioning
After the repaired and replacement parts are in place, the planetary reduction gear is assembled and the serviced electric motor is installed
Shipped after test run to check for any abnormalities in inspection items.
Planetary gear system servicing including electric motors
Even with geared motors, we can perform maintenance on both the electric motor and the reduction gear, such as planetary or cycloidal, if a set is brought in. By implementing and arranging the maintenance of both the mechanical and electric motor parts in-house, we can monitor the mutual status of the two parts and perform the maintenance in the optimal delivery time.
