| Troubles |
Cause |
Measures |
Heat
generation |
- Overload operation
- Too little or too much of lubricating oil
- Bad or inappropriate lubricating oil
- Bad oil seal
- Obstructing motor ventilation
- Short circuit of stationary coil
- Unparallel voltage
- Shaft bended or tight tension of connecting part
- Bad bearing(worn out, rough)
- Forced assembly of bearing area, friction of parts
|
- Adjusting load or replacing with larger size
- Check oil gauge
- Change with new oil
- Change with new oil seal
- Remove obstruction
- Repair
- Examine transformer
- Check shaft, adjust tension
- Replace
- Examine after dismantling and adjust
|
| Loud noise |
- Regular noise - poor joining of gear teeth, broken bearing
- High metal sound-lack of lubricating oil
- Broken bearing
- Contact between stationary and rotary
- Loosened stationary parts(shaft and gear, plunge joining part)
|
- Change gear, bearing, replenish lubricating oil
- Replenish lubricating oil
- Change bearing
- Repair
- Examine after dismantling, remove obstruction, and replace
|
Heavy
vibration |
- Worn out gear teeth
- Intrusion of obstruction
- Worn down and broken bearing
- Loosening of assembly parts(shaft, gear)
- Unparallel impeller(bad balance)
- Broken case and joining parts
|
- Change gear
- Remove obstruction and change lubricating oil
- Change bearing
- Examine after dismantling and reassemble
- Examine the status of load and rejoin
- Change
|
Leaking
oil |
- Broken oil seal
- Bad packing(joining part)
- Loosening of drain plug
- Broken and loosening of oil gauge
- Other welding parts leaking oil
- Worn out output shaft(oil seal part)
|
- Replace oil seal
- Change packing and reseal
- Tighten plug(teflon tape)
- Replace
- Reweld or replace
- Replace output shaft
|
Non-operation
or
trouble
operation
of motor |
- Broken fuse
- Shortage of starting torque
- Disconnection of coil
- Blackout or bad power supply
- Overload
- Jammed bearing and parts
|
- Examine capacity of fuse, replace
- Replace starting method or enlarge capacity
- Repair
- Examine power supply
- Measure current and examine load
- Reassemble or replace
|
