What are the common faults of transmission gears?

1. Gear overload
Gear overload is a common fault of transmission gears, usually caused by unreasonable mechanical structure design of the transmission device, harsh operating environment, and excessive workload. Gear overload can cause gear cracks, gear tooth surface damage, bearing overload and other faults, which can seriously affect production efficiency and safety.

2. Tooth surface wear
Tooth surface wear refers to the surface wear caused by friction between gears. There are many reasons for tooth surface wear, such as poor oil quality, poor lubrication, insufficient accuracy, or prolonged use. Tooth surface wear can lead to gear tooth deformation, increased noise, unstable power transmission, and in severe cases, the risk of gear tooth surface fracture.

3. Bearing damage
In transmission gears, bearings are the main components that bear loads and support the rotating shaft. Bearing damage is caused by the use of low-quality bearings, insufficient accuracy, poor lubrication, ball damage, and other reasons. Bearing damage can cause mechanical transmission system failure, resulting in abnormal noise, vibration, energy loss, and other issues, directly affecting the normal operation of the mechanical transmission system.

4. Excessive gear clearance
Excessive gear clearance refers to the gap between gears exceeding the standard value. It is usually caused by poor fit between gears, loose gear bearings, and other reasons. Excessive gear clearance can lead to unstable gear transmission, and even the occurrence of "top teeth" and "jumping teeth", further endangering the normal operation of the entire transmission system.
