Reducer low noise will be the trend of future industry development
With the development of science and technology, people pay more and more attention to environmental protection, and the establishment of an environment-friendly society is put on the agenda of the government.This is a social form in which man and nature coexist harmoniously, and its core content is the coordinated and sustainable development of human production and consumption activities and the natural ecosystem.
And environment-friendly technology, environment-friendlyproduct, Environment-friendly enterprises and environment-friendly industries are part of an environment-friendly society.
A gear reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of a motor (motor) to the required number of revolutions and obtain a larger torque.In the current mechanism used to transmit power and motion, the application range of the reducer is quite wide
The noise pollution of the reducer is also a major factor that destroys environmental protection, which will hinder people's normal rest, study and work. The low-noise reduction mechanism should be the subject of research and development by our reducer company.
Reducing the gear transmission noise during the operation of the reducer is an important research topic in the industry. Many scholars at home and abroad regard the change of gear tooth meshing stiffness in gear transmission as the main factor of gear dynamic load, vibration and noise.
Use the method of shape modification to minimize the dynamic load and speed fluctuation to achieve the purpose of reducing noise.This method has proved to be a more effective method in practice.However, with this method, the process requires shaping equipment, which is often not possible in the majority of small and medium-sized factories.
The noise of the worm reducer has a great influence on the stability of the work accuracy, the contact accuracy of the gear, the movement accuracy of the gear, the assembly accuracy and other aspects. If you want to reduce the noise of the reducer, you must know the cause of the noise. The noise is due to
The internal gear meshing produces vibrations caused by periodic alternating force on the bearing and casing.
After years of research, it is proposed to optimize gear parameters, such as modification coefficient, tooth height coefficient, pressure angle, center distance, to minimize the impact velocity of engagement, and the ratio of impact velocity of engagement to a certain value. Range, reducing or avoiding the impact of the meshing pitch circle
The gear design method can also significantly reduce gear noise.
