Gear Lubrication Failure Types

Mechanical equipment failures can take on various forms, including bearing wear, box cracks, screw cuts, coupling damage, surface corrosion, and more.

Gear lubrication failure types

The following are the most common lubrication faults that occur:

1. Inoperable, significant power loss

During the operation of mechanical equipment, the transmission parts often experience sticking, intermittent operation, and uneven operation. In such cases, the equipment is unable to transfer the load and transmit the motion correctly, resulting in significant energy loss.

2. Large vibration, high noise, and severe environmental pollution

At times, mechanical equipment may experience significant chattering after starting, leading to serious environmental pollution, thereby compromising the sense of security at the production site and affecting productivity.

3. High temperature, large thermal deformation, causing damage

After working for a specific duration, the parts of the reducer experience a sharp rise in oil temperature, sometimes accompanied by smoke and severe oil leakage. This situation causes some parts to melt, resulting in failure, and others to experience thermal deformation. As a result, there is a drop in accuracy, abnormal damage, and reduced material strength leading to further damage.

4. Key parts such as gear pairs, failure of the oil film between the toothed surfaces, leading to tooth surface damage

During the operation of the reducer, various parts may sustain damage, with the key parts such as gears, turbines, and bearings having the highest probability of being scrapped due to damage. Under harsh working conditions, these parts may not form a good oil film between the toothed surfaces, which may quickly lead to destruction.

Therefore, gear pairs, turbine pairs, and bearing surfaces may sustain surface failure such as pitting, gluing, plastic deformation, severe wear, impact fracture welding, etc. Consequently, the mechanical equipment may not function correctly.
