Reducer low noise era has arrived

Noise, whether to human body, equipment or building structure, will cause great harm. The advent of the era of low-noise reducers will end all this. Noise can affect people's sleep, its physiological function is affected to a certain extent, will make hearing decline, affect other people's system. Normal noise has little effect on buildings, but when the noise level exceeds 140 dB, it begins to destroy light buildings. For example, when a supersonic aircraft passes at low altitude, sudden changes in pressure and density occur in the front and rear of the aircraft. A N-shaped shock wave is formed after reflection from the ground. When it reaches the ground, it sounds like explosion. This special noise is called boom. Under the effect of the roar, buildings will be damaged to varying degrees, such as damage to doors and windows, broken glass, wall cracking, plastering and shaking, chimney collapse and other phenomena. Because of the slow attenuation of the bomb, it spreads far and has a wide range of influence. In addition, the use of air hammer, piling or blasting near buildings can also cause damage to buildings.

The equipment will be affected by the following three conditions:

1. Disturbance of instruments and equipment

2. Failure of instruments and equipment

3. Damage to instruments and equipment

In modern society, people pay more and more attention to environmental protection, and the establishment of an environment-friendly society has been put on the agenda of the government. This is a social form of harmonious coexistence between man and nature. Its core connotation is the coordinated and sustainable development of human production and consumption activities and natural ecosystem. The environment-friendly technology, products, enterprises and industries are the components of the environment-friendly society.

Gear reducer is a kind of power transmission mechanism, which reduces the turning number of motor (motor) to the desired turning number by using the speed converter of gear, and obtains a larger torque. At present, the reducer is widely used in the transmission mechanism of power and motion. The noise pollution of decelerator is also a major factor that destroys environmental protection. It will hinder people's normal rest, study and work. The low noise deceleration mechanism should be the research and development topic of our deceleration Machinery enterprises. The noise of gear reducer has great influence on the working stability, contact accuracy, kinematic accuracy and assembly accuracy of gears. To reduce the noise of gear reducer, we need to know the cause of noise. The noise of gear reducer is due to the periodic interaction of gears meshing in the process of its operation. Vibration caused by variable force acting on bearing and box.

By optimizing gear parameters, such as displacement coefficient, tooth height coefficient, pressure angle and center distance, the meshing impact speed is minimized, the ratio of meshing impact speed to meshing impact speed is in a certain range, and the gear design method to reduce or avoid meshing pitch impact is proposed after years of research, which shows that it is correct. It can obviously reduce gear noise.

Reducing the gear transmission noise of gear reducer is an important research topic in the industry. Many scholars at home and abroad regard the change of gear meshing stiffness as the main factor of gear dynamic load, vibration and noise. The method of modification is used to minimize the fluctuation of dynamic load and velocity in order to reduce noise. This method has proved to be an effective method in practice. However, with this method, there is a need for modification equipment in the process, and it is often impossible for small and medium-sized factories to implement it.
