Car gears may be worn or damaged during use, so regular inspection and maintenance are necessary. When the gear is damaged, the following methods can be used for repair:
Tooth inlay method: For gears with low load and low speed, when individual teeth break, tooth inlay method can be used for repair.
Partial welding of gear teeth: When individual teeth of the gear are broken or severely damaged, the arc welding method can be used for local welding.
Multi layer welding on tooth surface: When a few tooth surfaces of the gear are severely worn, multi-layer welding on the tooth surface can be used for repair.
Grinding method: After welding according to the appropriate tooth profile, it is manually polished and then a smooth surface is achieved through running in during operation. This method has a simple process, but the paired gears have significant wear and low accuracy, making it suitable for repairing open gears with very low rotational speeds.
Cutting method: During the welding process, a certain amount of margin is left for the gear, and then it is cut on the machine tool to achieve high precision and production efficiency.
Automotive gears are key components in the automotive transmission system, with a wide range of applications and important functions. During use, regular inspections and maintenance are required to ensure its normal operation and extend its service life.
