Noise-reduction gears are designed.

In general, the sources of gear transmission noise are ascribed to the load, vibration frequency, and gear ratio. Bearing rotation and wheel friction, As a result, the design of noise-canceling gears should be based on these considerations as well. As a result, we should consider these factors when designing noise-canceling gear.

 

1.   Pay attention of Loading 

 

The load is mostly determined by the gears’ manufacturing weight. Gear selection is based on the product’s ability to endure the weight of production, that is, different products’ weights must be considered. The weights of the gears are suitably changed to prevent some of the gears from being unable to hold the associated weight throughout the transmission operation, resulting in noise-created noise.

 

2 The vibration frequency

Some gears pause friction between huge, quick, resulting in vibration speed is too fast, generating noise. In Gear design should pay attention to the pace of gears, that is, within a given time frame to specify the number of weeks it should be completed. Rather than allowing it to rotate too quickly, the number of weeks of operation.

 

3 Gear rubbing to reduce noise in a gearbox

 

As previously stated, excessive friction between the gears will result in excessive vibration and large noise. To reduce friction between gears, while selecting gears, strive to choose a smooth appearance of gears, keeping in mind Choose gears with a smooth appearance and low friction; additionally, you can introduce lubricant into the gears to improve performance. The efficient operation of the gears.

 

4 Bearing rotation to reduce noise in a gearbox

 

Not only does the designer of the gear bearing design need to be present but so must the inspector of the gear bearing circumference. Supervision. Requirements, the designer of the trial bearing guarantee duration must be able to tolerate the fault in the gear transmission. The difference between the gear’s design and the gear itself projected that there could be an acceptable range of design flaws.

 

5 Improve the process of gear lubrication to reduce noise in a gearbox

To begin reducing noise in gear lubrication, the lubricant should not be the primary consideration. Should also produce A new gear lubrication system that saves grease while improving gear efficiency and reducing noise. Although According to research, centrifugal lubrication is one of the most effective ways to effectively reduce gear noise. This indicates that the gearbox is oiled within a certain time frame. The gearbox is inspected within a certain time range, and seriously broken and degraded gears are replaced as soon as possible. Based on this, a small hole is drilled at the bottom of the gears, and the lubricant is injected through the small hole utilizing centrifugal force. On this premise, a small hole at the bottom of the gear is drilled through which the lubrication is fed and the used lubricant waste is eliminated. It is feasible to construct the gears in this manner. This method efficiently makes the gears rub against each other while avoiding the gear transmission noise caused by poor lubrication.

 

6 The tooth form correction

The top of the gear is meshing due to the tooth form mistake, and the meshing accuracy is low. We want to improve the meshing precision. We apply the tooth form adjustment approach to eliminate gear noise, which is also highly effective. First, we apply the red powder to the teeth. Following the meshing research, utilize shaping to correct the meshing point of the gear, ensuring that the meshing point of the gear is distributed as evenly as possible in the indexing. to increase the gears’ meshing precision The transmission precision of the gears is greatly improved when they are carefully mounted. The goal of noise reduction has been met. Furthermore, helical gear transmission is smoother, has less meshing impact, and is less likely to cause resonance. In the same way, spur gear transmission, As a result, switching from spur to helical gear transmission is an essential way for reducing gear transmission noise. From the standpoint of gear design, as long as the gear vibrates during operation, sound waves are formed, which in turn Noise is produced. The noise produced by the gear drive not only has an impact on the working environment but also on the manufacture of particular precision items. Accuracy will also have an impact on the production of some precision items, with specific challenges requiring appropriate noise-reduction methods.

 

7. Setting Sound Barriers or Enclosures to reduce noise in a gearbox

For extreme cases, you can choose acoustic panels that are available for higher frequency noise levels. Panels can be placed around the gearbox to minimize the amount of sound near employees.

 

We could also install an enclosure around the sound source. The enclosure should be hard-shelled and airtight, with an inner layer made of sound-absorbing material. However, if you use an enclosure, be sure to include ventilation or you may risk overheating the industrial gearbox or other components.

 

8. Ensure that personnel follows the necessary safety procedures.

 

When working with noisy equipment, your personnel should also take care. Instruct your personnel to wear ear plugs and other safety equipment wherever possible. Employees should also have frequent hearing tests to see how noise affects their environment. Finally, perform routine testing to ensure that your facility is working safely.
