Reasons for Gear Failure and Countermeasures

Reasons for gear failure
1. Overloading: When gears are subjected to excessive load pressure during transmission, it can cause excessive contact pressure on the tooth surface, exacerbating friction and wear. This is one of the most common causes of gear failure.
2. Material and manufacturing defects: Defects in the material and manufacturing process of gears can affect their strength and toughness, making them prone to failure.
3. Insufficient lubrication: The friction surface of the gear needs sufficient lubrication to reduce friction and wear. Once the lubrication is insufficient, it will intensify the friction state of the gear, causing overheating and wear, leading to failure.
4. Insufficient accuracy: The manufacturing accuracy of gears is directly related to parameters such as tooth profile and backlash. If the manufacturing accuracy of gears is insufficient, it is easy to cause tooth surface contact fatigue, leading to gear failure.
5. Corrosion and rusting: Gears are affected by corrosion and rusting during use, which can cause a decrease in the surface quality of the tooth surface and gear shaft, accelerating the occurrence of failure.

Countermeasures for gear failure
1. Choose high-strength materials: Using high-strength and high toughness materials to produce gears can improve their service life and fatigue resistance.
2. Precise manufacturing: Precise machining is necessary during gear manufacturing to ensure the strength and toughness of the tooth surface.
3. Strengthen the lubrication and cooling of gears: Strengthening the lubrication and cooling of gears can effectively reduce the occurrence of tooth surface wear and tooth surface contact fatigue.
4. Inspection and maintenance: During the use of gears, regular inspection and maintenance are required, and any damages or malfunctions found should be repaired and replaced in a timely manner.
5. Prevention and lubrication: Necessary prevention and lubrication measures should be taken for the working conditions of gear use, such as avoiding overload, corrosion, and rusting.

In short, gear failure is a major hidden danger that affects the normal operation of production, and it is necessary to strengthen daily maintenance and repair to reduce the occurrence of gear failure. At the same time, taking the above measures can effectively prevent and solve the problem of gear failure, ensuring the safety and normal operation of production.
