Although proper usage and maintenance of the gearbox cannot reduce the noise level or ensure transmission accuracy, it can prevent the degradation of performance indicators and extend the service life.
1. Internal Cleaning
The cleanliness of internal components is essential for ensuring the normal operation of the gearbox. The entry of any impurities or contaminants can affect and damage the transmission system, leading to the generation of noise.
2. Operating Temperature
Maintaining the gearbox at the appropriate operating temperature helps prevent deformation of components due to excessive heat, ensuring proper gear engagement and minimizing noise amplification.
3. Timely Lubrication and Correct Use of Lubricants
Improper lubrication and incorrect use of lubricants can cause significant damage to the gearbox. High-speed gear surface friction generates a considerable amount of heat, and inadequate lubrication can lead to gear damage, reduced accuracy, and increased noise.
Proper design should include appropriate clearances within the gear pair (clearance between non-working surfaces of meshing gears) to compensate for thermal deformation and accommodate lubricants. The correct use and selection of lubricants ensure safe and efficient operation, delay degradation, and maintain a stable noise level.
4. Proper Usage of the Gearbox
Using the gearbox correctly can minimize component damage and ensure a stable noise level. Gearbox noise tends to increase with increased load, so it is important to operate within the normal load range.
5. Regular Maintenance
Regular maintenance (such as oil changes, replacement of worn-out components, tightening of fasteners, removal of internal debris, adjustment of clearances to standard values, and verification of geometric accuracy) can improve the gearbox's ability to resist degradation of noise levels and maintain stable performance.
Conclusion：Controlling gearbox noise is a comprehensive engineering process that involves the design, manufacturing, installation, usage, maintenance, and even upgrading of the transmission system (gears, housing, connecting components, bearings, etc.). It imposes various requirements not only on designers and manufacturers but also on installers and maintenance personnel. If any of these aspects are not effectively controlled, the control of gearbox noise will be compromised.
