How can JK Low Noise Spiral Helical Gear Reducer avoid resonant frequencies to achieve noise reduction?

1. Industrial noise: a serious problem that needs to be solved urgently
The industrial production environment is complex and diverse, and the noise sources are extensive and strong. In mining operations, when the crusher crushes the ore, the strong mechanical force causes the ore to collide with each other, and the noise generated is deafening, which not only damages the hearing of the mine workers, but also interferes with the surrounding ecological environment. The blast furnace blower in the metallurgical industry, with its high-speed rotating impeller and strong airflow, produces extremely high noise intensity. Workers who are in this environment for a long time face a series of health problems such as hearing loss, insomnia, and anxiety. According to a study by the World Health Organization (WHO), long-term exposure to a noise environment above 85 decibels (dB) will damage people's hearing, and in many industrial sites, the noise intensity often easily exceeds 90dB, and even in some large forging workshops, the noise can be as high as 110dB or more.
Inside the workshop, various types of processing equipment are densely arranged, and the noise generated by their respective operations overlaps with each other, forming a noisy sound wave. This not only affects the normal communication between workers, leading to information transmission errors, thereby reducing production efficiency, but also causes serious interference to some production links with extremely high precision requirements, such as electronic chip manufacturing and precision instrument processing. Equipment vibration caused by noise may cause deviations in chip circuits, increase the defective rate, and bring huge economic losses to enterprises. At the same time, as society's attention to environmental protection and occupational health continues to increase, governments of various countries have introduced strict industrial noise emission standards. If enterprises cannot effectively control noise, they may not only face high fines, but also affect the social image and sustainable development of enterprises.

2. The secret of the structural design of low-noise spiral helical gear reducers
The low-noise spiral helical gear reducer adopts a compact and optimized layout in structural design. This design concept runs through the entire reducer structure. Gears are the core components of reducers, and their parameter design is crucial. The performance of the reducer can be greatly affected by carefully designing the gear's modulus, number of teeth, helix angle and other parameters. The modulus determines the size and load-bearing capacity of the gear. Reasonable modulus selection can make the gear more stable when transmitting power and reduce impact and vibration. The determination of the number of teeth is closely related to the transmission ratio. The appropriate number of teeth can ensure the accuracy and stability of the transmission. The design of the helix angle is even more critical. The helix angle of the helical helical gear makes the tooth surface contact line inclined. During the transmission process, the number of teeth participating in the meshing increases and the overlap increases. This is like multiple pinions working together to share the load, greatly reducing the impact force borne by a single gear, thereby reducing the noise caused by the impact. Relevant research data shows that under the same transmission conditions, the impact load of the helical helical gear can be reduced by 30% - 50% compared with the spur gear.
In addition to the optimization of gear parameters, the structure and size design of the housing should not be ignored. As the outer shell of the reducer, the housing not only protects the internal components, but also has an important impact on the overall stability and noise control of the reducer. By optimizing the structure of the housing and adopting a reasonable rib arrangement and wall thickness design, the rigidity of the housing can be enhanced and the deformation and vibration during operation can be reduced. At the same time, optimizing the size of the housing to match the layout of internal gears and other components can effectively reduce the resonance area of ​​the internal space. Resonance is one of the important factors of noise amplification. When the natural frequency of the equipment is close to the external excitation frequency, resonance will occur, causing a sharp increase in noise. JK Low Noise Spiral Helical Gear Reducer cleverly avoid the resonance frequency through precise structural design, thereby greatly reducing the generation of noise.
For example, in some medical equipment with extremely high noise requirements, such as the drive system of magnetic resonance imaging (MRI), the requirements for noise control are almost harsh. The low-noise helical gear reducer used has been repeatedly simulated and tested, and its structural resonance frequency is completely staggered with the operating frequency of the equipment. During the design process, engineers used advanced computer-aided design (CAD) and finite element analysis (FEA) technology to optimize the structure of the gear and the housing for multiple rounds. By simulating the stress distribution, vibration mode and noise propagation path under different working conditions, the parameters of the gear and the structure of the housing are accurately adjusted to ensure that the reducer can maintain an extremely low noise level during operation, which provides a guarantee for the precise operation of medical equipment.
In the field of high-end electronic manufacturing equipment, such as the precision transmission system of chip lithography machines, there are also strict requirements for noise and vibration. JK Low Noise Spiral Helical Gear Reducer effectively reduce noise and vibration during equipment operation by optimizing structural design. In actual applications, after testing by an acoustic testing agency, the chip lithography machine using a low-noise helical gear reducer has an operating noise reduction of more than 15dB compared to a traditional reducer, and the vibration amplitude of the equipment is also significantly reduced, greatly improving the accuracy and yield rate of chip manufacturing.

III. Significant noise reduction effect of structural design in actual applications
In the textile industry, the high-speed operation of looms is one of the main sources of workshop noise. Traditional reducers generate a lot of noise during operation due to unreasonable structural design. The situation has been greatly improved after the use of JK Low Noise Spiral Helical Gear Reducer. In the production workshop of a large textile factory, after the loom reducer was replaced, the noise environment in the workshop was significantly optimized. According to the data of the acoustic testing agency, under the same production conditions, the operating noise of the loom using a low-noise helical gear reducer was reduced by about 12dB compared to before. This noise reduction effect makes the working environment in the workshop more pleasant, the communication between workers is smoother, and the production efficiency is also improved. According to the factory's statistics, after replacing the low-noise helical helical gear reducer, the workshop's production efficiency increased by 10% - 15%.
The food processing industry also has very high requirements for the noise of the production environment, especially in the production process of some products with strict hygiene and quality requirements, such as chocolate production lines. The noise generated by the operation of mixing, molding and other equipment will not only affect the working status of workers, but also have potential impacts on the quality and hygiene safety of food. The application of low-noise helical helical gear reducers effectively solves this problem. In a chocolate production company, after replacing the reducer of the mixing equipment on its production line, after actual monitoring, the equipment operation noise was reduced from the original 88dB to 76dB, which fully meets the noise standards of food processing workshops. This not only ensures the production quality of food, but also creates a relatively comfortable working environment for workers, and improves the workers' work enthusiasm and work efficiency.
