Maintenance of hydraulic motors

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 KBK Engineering is also involved in the maintenance of hydraulic equipment. Oil leakage from the inside of hydraulic motors, hydraulic cylinders and other machines that generate large forces via oil not only reduces the performance of the machine, but can also have a negative impact on the quality of the products produced by machines controlled by hydraulics. This section introduces hydraulic motor maintenance, which is an example of hydraulic equipment maintenance.

Hydraulic motors that have stopped working due to oil leaks.

油圧モーター分解1
When the lid is opened, oil residue deposits are observed
油圧モーター分解3
The seal is missing, probably due to deterioration over the years. It no longer functions as a seal.
油圧モーター分解4
The back-up ring is also finely cracked. It appears to have not been serviced for a long time.
油圧っモーター分解4
Disassembly is complete. Many of the plastic parts have disappeared, while many of the metal parts appear to be sound.

Parts inspection and arrangement

油圧モーター部品1
The oil seal collars are less painful at low RPMs and should be diverted.
油圧モーター部品2
Because of bending and other problems, it was deemed to be newly manufactured.

Assembly

油圧モーター組み立て1
Back-up rings are also available and new ones are being assembled
油圧モーター組み立て2
The ball is now inside the motor and the assembly is in the final stages!
油圧モーター試運転
Assembly is complete and commissioned.

Hydraulic equipment is also serviced

EveIn addition to rotating machinery, the company also works on the maintenance of hydraulic equipment. We diagnose, procure parts for, manufacture, assemble, test run and maintain hydraulic equipment such as hydraulic cylinders and hydraulic motors that have been requested for servicing, so that machines that have stopped working can be restored and given the opportunity to work again.
