The noise in reducer fasteners
The loose of fasteners
Tighten bolt/nut to specified torque, replace damaged bolt/nut
Reducer’s noise changes
Gear tooth get damaged
Contact customers service department to check all the gear, replace damaged bolt/nut
Bearing clearance large gap
Contact customer service department, adjust bearing clearance
Broken bearing
Contact customer service department, replace damaged bearing
Too high working temperature
High oil level of the inside box body
Check oil surface height, adjust if necessary
Long-used oil
Contact customer service department, check the last time oil change, replace if necessary
Oil gets severely contaminated
Contact customer service department, change oil
For reducer that equipped with lubricating oil cooling system, too low or too high coolant flow rate
Comprehensively regulate import and export of pipeline valves, check the free flow of water-cooling device
Too high temperature for coolant
Check temperature and adjust according to demand
Too low oil flow through water cooling device, reason: oil filter seriously blocked
Oil filter cleaning
Oil pump mechanical failure
Contact customer service department, check whether the function of oil pump is normal or not, carry out repair or change the oil pump if necessary
Reducer that is equipped with fan, fan cover’s air inlet and/or body get seriously polluted
Fan cover and housing cleaning
Reducer equipped with cooling spiral pipe: cooling spiral tube fouling inside
Contact customer service department, clean or replace spiral pipe
Too high temperature in bearing
Too high or too low oil level in reducer box
Check oil surface height at room temperature and refueling on-demand
Long-used oil
Contact customer service department, check last time oil change
Oil pump’s mechanical failure
Contact customer service department, check whether the pump work normally or not, repair or change a new oil pump
Broken bearing
Contact customer service department, check the vibration measuring data, check and change the bearing according to the need
Bearing amplitude rise
Broken bearings
Contact customer service department, check the vibration measuring data, check and change the bearing according to the need
Damaged gear
Contact customer service department, check and change gear according to need
Non-return device temperature is too high, check function failure
Damaged device
Contact customer service department, check and change non-return device according to need
Reducer leakage
Enclosure cover or joint sealing adverse
Check seal and connection, if necessary, change a new seal
Radial shaft seal failure
Contact customer service department, change new radial sealing ring
Have water in oil
Have sundry in oil
Check if water does exist in oil, and laboratory analysis
Lube oil cooler or the cooling spiral pipe failure
Contact customer service department, find out leakage position, change water cooler
Reducer machine ventilation when come up with cool air and condensation
Use the appropriate heat preservation material to guard the speed reducer, close air export or change its direction on structure
Pressure alarm monitoring device, equipped with a pressure lubrication device, lubricating oil water cooling and air cooling is the reducer
Oil pressure＜0.5bars
At room temperature check the oil level height, according to the need to go check the oil filter, according to the need to change, contact the customer service department, check the normal functioning of the oil pump, oil pump repair or replace

Double switching filter clogging
According to the specification toggle switch filter will be blocked filter down and clean up
Oil supply system fault
See operating instructions on oil supply system description
Motor does not start
Power interrupt
Check wiring, when need correct
Fuse fusing
Replace the fuse
Motor protection device has action
Check motor protective device Settings are correct, when need discharge failure
Motor contactor action, not in the control system failure
Check motor contactor control, when need troubleshooting
