As for the operation of gears and racks, the causes of noise generated by gear transmission can be attributed to load, vibration frequency, gear friction, and bearing rotation. Therefore, in the prevention of gear noise, research should also be based on these points.

1. Load

As for the production weight that the load is mainly borne by the gears, therefore, when selecting gears for corresponding production products, it is necessary to still determine the production weight that the products can bear, that is, to exchange gears appropriately according to the weight required by different products, to avoid noise caused by some gears that cannot bear the corresponding weight during the transmission process.

2. Frequency of vibration

Due to the high friction and high speed between some gears, excessive vibration and noise are generated. In the design of gears, attention should be paid to the movement speed of the gears, that is, the number of cycles they should run within a certain period of time should be specified, rather than allowing them to rotate too quickly.

Gear friction

As mentioned above, excessive friction and vibration between gears can result in significant noise. To reduce friction between gears, it is advisable to choose gears with a smooth surface. Remember not to choose gears with rough surfaces and high friction. In addition, lubricant can also be injected into the gears to improve the operation of gear components.

4. Bearing movement

Not only does it require the design of this pair of gear bearings, but it also includes the supervision of the inspector on the number of cycles of the gear bearings. The designer is required to ensure that the bearing guarantee period of the design can withstand the error that should be borne in the gear transmission, as well as the possible reasonable range of design defects predicted in the design of the gear.

The above is an introduction to some methods to prevent gear and rack noise. Although the above are some methods to prevent gear noise, they are actually some methods to protect gears. I hope it can help everyone.
