1. Fast gear vibration speed
The excessively fast gear vibration speed is mainly caused by the excessively frequency in the gear transmission. The high vibration speed during gear operation will affect the frequency of vibration and make noise.
2. Resonance
Everyone knows that resonance can make noise. Gear transmission will naturally also resonate during operation. The resonance brought by the gear transmission is based on the vibration generated by the difference in the rigidity of the gear itself and the vibration generated by the friction between the gears at the same vibration frequency. At this time, the interaction between the two is prone to resonance and the noise caused by resonance appears .
3. Insufficient gear surface smoothness
As we all know, if two objects are smooth, the vibration generated when rubbing against each other will be small. However, if gear surface is not smooth, the friction will be large large when they rub against each other. Noises appears.
4. Lack of correct lubrication
In gear maintenance and noise reduction, not only good lubricants can reduce friction between gears, but the use of good lubricants is also an important method to reduce noise.
Measures to prevent gearbox noise
1. Load
Load is the production weight that the gear can bear. Therefore, when selecting the gear for the corresponding production product, gear should be appropriately adjusted according to the weight required by different products. The replacement of the gears can avoid gearbox noise caused by overloading.
2. Frequency of vibration
When designing the gears, attention should be paid to the speed of the gears, that is, the number of cycles that they should run within a certain period of time, rather than let it turns too fast
3. Gear friction
In order to reduce the friction between gears, we should choose smooth gears. In addition, lubricants can also be injected into the gears to improve the effective operation of gears.
