With the rapid development of the industrial and mechanical industries, gear reducers play an important role in an increasing number of industrial and mechanical equipment. For example, the planetary gear reducer and planar secondary enveloping toroidal worm reducer developed and produced by HeZong Heavy Industry are widely used in equipment in various fields such as engineering machinery, marine auxiliary machinery, mining machinery, textile printing and dyeing machinery, industrial production lines, etc.

Mechanical and industrial enterprises are also paying increasing attention to the maintenance and repair of gear reducers. So, how to do a good job in the maintenance and repair of gear reducers?

Suitable maintenance cycle and content

The maintenance cycle of gear reducers should be determined based on the actual usage, working environment, and load conditions of the equipment.

Regardless of the working state of the gear reducer, it can be inspected daily through visual observation to check for any dripping or obvious damage, and to listen for any abnormal noise such as knocking or rubbing during operation.

For gear reducers with mild and moderate loads, it is recommended to perform a shutdown inspection every 6 months.

For gear reducers with heavy loads or working in harsh environments, it is recommended to perform a shutdown inspection every 3 months.

The inspection mainly includes:

1. Check the oil quality (color, transparency), oil quantity, and filter status of the lubricating oil, analyze and replace the lubricating oil;

2. Remove oil stains and debris from the parts and gearbox, clean the ventilation cap and oil stains;

3. Check the cracks, wear, and meshing of the gears, and repair or replace them in severe cases;

4. Check the status of bearings and bearing clearances, and carry out maintenance and adjustment;

Common faults and causes of gear reducers

The causes of abnormal noise in gear reducers include loose fasteners, damaged gear teeth, excessive bearing clearance, damaged bearings, poor alignment, and loose casing.
