What are the common causes of gear damage in new energy vehicles?

What are the common reasons for the damage of the gears of new energy vehicles to the transmission gear manufacturers below?

1, the quality of the new energy vehicle gear itself, the gear is usually alloy raw materials, raw materials, equipment, processes, inspection and other factors will lead to unqualified gear production or quality decline, gear assembly, the quality is not good, the service life will directly decline.

2. If the driving operation is incorrect or the driving habits are not good, the abnormal work of the gearbox will also lead to damage to the gears of the new energy vehicle. Common causes are wrong driving operations and poor driving habits. For example, a manual car goes straight into reverse gear without using a clutch. Perhaps when a vehicle mistakenly enters reverse gear at low speeds, it can lead to inconsistent friction and collision of gears, which is often referred to as jam teeth, which can easily lead to gear damage. In addition, poor driving habits can also lead to longer gear life and early damage.

3. Improper oil selection or oil shortage will also lead to excessive wear and damage to the gears. It usually requires lubrication. Prominent lubrication is necessary to improve the efficiency of power transmission and reduce wear. When the viscosity of the oil used is not suitable, the amount of oil is low, the gearbox lubrication is poor, the wear is aggravated, and long-term work is easy to form gear damage or other mechanical failures.
