Oil leakage from the reducer
Thread Content
The reducer’s shaft seal is leaking oil; the seal used is a standard lip seal. There are scratches on the shaft now – what are some good ways to address this issue?
Fill it up, but don’t overfill it; half full is sufficient. Overfilling leads to poor heat dissipation and can easily damage the shaft seal
Smooth out the scratches on the shaft with sandpaper; if they are too deep, consider cutting at the sealing area, then fitting a sleeve and grinding it back to the original size.
A oil level of 1/2 is sufficient; any scratches on the shaft can be repaired.
Depending on the specific damage to the shaft, methods such as cold welding, sleeve installation, or electroplating can be considered for repair
Are there any on-site repair methods?
