Below are some common reasons for gearbox gear damage, including beach bike gears, gear customization, and Zhejiang automotive gear manufacturers:

1. The quality problem of gears themselves is that gears are usually made of alloy materials and are produced and processed by automotive parts manufacturers on dedicated production lines. Many factors such as materials, equipment, processes, and inspections during this process can cause the production of gears to be unqualified or the quality to decrease. After assembly, the quality of these gears is poor, and their service life will directly decrease;

2. Incorrect driving operation or poor driving habits can also cause gear damage due to abnormal operation of the gearbox, which is commonly caused by incorrect driving operation and poor driving habits. For example, when a manual transmission car directly shifts into reverse gear without using a clutch, or when the vehicle accidentally shifts into reverse gear while driving at low speeds, it can cause non engagement friction and collision of the gears, commonly known as "gear jamming", which can easily cause gear damage. In addition, poor driving habits accumulated over a long period of time can also lead to a decrease in the lifespan of gears and premature damage;

3. Improper selection of engine oil or lack of engine oil can also cause excessive gear wear and damage. Gearbox gears usually require lubrication, and good lubrication is a necessary measure to improve power transmission efficiency and reduce wear. When the viscosity of the oil used is not suitable and the amount of oil is low, the lubrication of the gearbox is poor, wear is exacerbated, and long-term operation can easily cause gear damage or other mechanical failures.
