Reasons and Countermeasures for the Formation, Use and Maintenance of Gear Transmission Noise

Although the correct use and maintenance of the gear transmission system can not reduce the noise level of the system and ensure the transmission accuracy, it can prevent the deterioration of its indicators and increase the service life.

1. Internal cleaning of the transmission system
The internal cleaning of the transmission system is the basic condition to ensure the normal operation of the gear, and the entry of any impurities and dirt will affect and damage the gear transmission system, eventually resulting in noise and damage to the transmission system.

2. Temperature at which the system works normally
Ensure the normal working temperature of the transmission system, prevent the system from deformation due to excessive temperature rise, resulting in abnormal meshing, which can prevent the increase of noise.

3. Timely lubrication and correct use of oil products
Careless lubrication and the wrong use of lubricating grease will cause immeasurable damage to the system. Ensure that the system is timely and correctly lubricated, which can keep the system within a certain noise level range and delay the deterioration trend. High-speed running gear, tooth surface friction will produce a lot of heat energy, improper lubrication, will lead to tooth damage, affect the accuracy, noise will also increase.

The design requires the gear pair to have a proper gap (the gap between the non-working faces of the meshing gear teeth to compensate for thermal deformation and store lubricating oil). The correct use and selection of lubricating oil can ensure the safe and effective operation of the system and stabilize the noise level.

4. Correct use of gear motion system
Using it in accordance with the normal operation sequence of the system can avoid damage and damage to the system to the maximum extent and ensure a stable noise level. The system is used in the normal load range of the system, because the transmission noise of the gear transmission system increases with the increase of the load.

5. Regular maintenance and maintenance
Regular maintenance (oil change, replacement of worn parts, fastener loose parts, removal of internal debris in the system, adjustment of the gap to the standard value, verification of various geometric accuracy, etc.) It can improve the ability of resisting noise level degradation and maintain the stability of the system.
