Common faults and solutions of WD80-60-1 worm gear reducer

Common faults and solutions of WD80-60-1 worm gear reducer are as follows:

1. Excessive oil temperature and severe heating

Reason: Insufficient or deteriorated lubricating oil, incorrect oil grade, excessive load, tight assembly, blocked ventilation cap, poor heat dissipation.

Solution: Add or replace VG220/320 worm gear oil; Reduce load; Check and adjust the meshing clearance and bearing preload; Unclog the ventilation cap; Improve ventilation and heat dissipation.

2. Oil leakage

Reason: Oil seal aging and damage, joint surface sealing failure, high oil level, excessive pressure in the box, loose bolts.

Solution: Replace the skeleton oil seal; After cleaning the joint surface, reapply sealant and evenly tighten the bolts; Adjust the oil level to the centerline of the oil gauge; Clear the ventilation cap.

3. Abnormal noise, loud noise

Reason: Poor lubrication, damaged bearings, improper meshing clearance, loose fasteners, and foreign objects entering.

Solution: Check and replenish lubricating oil; Replace damaged bearings; Adjust the meshing clearance of the worm gear and worm; Tighten the bolts of each part; Dismantle and clean foreign objects.

4. Large vibration

Reason: Poor alignment with the motor/equipment, unstable foundation, bearing wear, and severe wear of the worm gear.

Solution: Recalibrate coaxiality; Strengthen the installation foundation; Replace worn bearings; Replace the worm gear and worm gear pair when the wear exceeds the limit.

5. Insufficient output torque, weakness, low transmission efficiency

Reason: Worn worm gear, tooth surface adhesion, lubrication failure, overload, internal jamming.

Solution: Replace worn or glued worm gears; Replace with new lubricating oil; Reduce load; Disassemble and inspect to eliminate any stuck points.

6. Motor overload and tripping

Reason: Excessive load on the reducer, internal jamming, bearing locking, worm gear biting, and mismatch between the motor and the model.

Solution: Check and reduce the load; Disassemble the machine to troubleshoot issues such as jamming, locking, and biting; Match the motor power according to the selection parameters.

7. Overheating of bearing parts

Reason: Lack of oil, deterioration of grease, damage to bearings, tight assembly, excessive axial force.

Solution: Supplement or replace lubricating grease; Replace bearings; Adjust the assembly gap again; Check the axial force and improve it.
