In today's society, people are paying more and more attention to environmental protection, and establishing an environmentally friendly society has been put on the agenda of the government. This is a social form of harmonious coexistence between humans and nature, whose core connotation is the coordinated and sustainable development of human production and consumption activities with the natural ecosystem. Environmentally friendly technologies, products, enterprises, and industries are components of an environmentally friendly society.

A reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of an electric motor (motor) to the desired number of revolutions and obtain a larger torque. Among the mechanisms currently used for transmitting power and motion, the application range of reducers is quite extensive. The noise pollution of reducers is also a major factor that damages environmental protection, which can hinder people's normal rest, study, and work. Low noise reducers should be a research and development topic for our reducer machine enterprises.

Reducing the gear transmission noise during the operation of reducers is an important research topic in the industry. Many scholars at home and abroad consider the changes in tooth mesh stiffness in gear transmission as the main factors of gear dynamic load, vibration, and noise. By using the method of shaping, the dynamic load and velocity fluctuations are minimized to achieve the goal of reducing noise. This method has been proven to be a more effective approach in practice. However, using this method requires shaping equipment in the process, which is often not feasible for large, medium, and small factories in Guangzhou.  

The noise of a reducer has a significant impact on the stability and accuracy of operation, contact accuracy of gears, motion accuracy of gears, assembly accuracy, and other aspects. To reduce the noise of a reducer, it is necessary to know the cause of the noise. The noise of a reducer is caused by the periodic alternating force generated by the meshing of gears inside the machine during its operation, which affects the bearings and housing and causes vibration.  

After years of research, a gear design method has been proposed to minimize the meshing impact velocity by optimizing gear parameters such as displacement coefficient, tooth height coefficient, pressure angle, and center distance. The ratio of meshing impact velocity to meshing impact velocity is within a certain numerical range, reducing or avoiding meshing pitch circle impact. This method can also significantly reduce gear noise.  

China Gearbox Network believes that with the continuous improvement of processing and manufacturing technology, the development and implementation of advanced assembly processes, and strict adherence to relevant national and international standards, the quality of gearboxes can be improved and the noise of gearboxes can be reduced. This is not only a responsibility that enterprises should bear for an environmentally friendly society, but also an inevitable requirement of the times. Low noise reducers will undoubtedly gain a place in future industrial manufacturing, bringing real economic benefits to our reducer enterprises.
