The key technical characteristics and elements of construction machinery gear mainly include the following points:
1. High carrying capacity: Construction machinery gears need to withstand large loads and torques, so they must have high carrying capacity to ensure stable work in complex operating environments.
2. Wear resistance: Because construction machinery is often in contact with sand, dirt and other harsh environments during use, the gear surface must have good wear resistance to reduce wear and extend service life.
3. High-precision machining: The machining accuracy of the gear directly affects the stability of the gear mesh and the efficiency of the mechanical transmission. Therefore, high precision gear machining technology is the key, including gear grinding machining, gear tooth surface precision control.
4. Vibration reduction design: In order to reduce mechanical vibration and noise and improve the reliability of gear, vibration reduction design is one of the key elements. For example, the vibration reduction gear patent applied by Guangxi Liugong Machinery Co., LTD., reduces the speed fluctuation and torsional vibration through special structural design.
5. Material selection: Choosing the right material is crucial to the performance of the gear. Commonly used materials include high-strength steel, alloy steel, etc., which have good mechanical properties and wear resistance.
6. Heat treatment process: Heat treatment process can improve the performance of gear materials, improve its hardness and wear resistance, is a key link in the gear manufacturing process.
7. Surface treatment technology: Through surface treatment technology such as carburizing, quenching, nitriding, etc., can improve the hardness and wear resistance of the gear surface, extend the service life of the gear.
8. Structure optimization: Through the optimal design of the gear structure, the strength and stiffness of the gear can be improved, the stress concentration can be reduced, and the overall performance of the gear can be improved.
9. Repair and maintenance: Reasonable repair and maintenance strategy is also an important part of ensuring the normal work of construction machinery gear, including regular inspection, lubrication, replacement of damaged gear and so on.
Combining these factors, the design and manufacture of construction machinery gears need to consider various technical requirements to ensure their reliability and efficiency in complex and harsh operating environments.
