How do Chinese electrical machinery suppliers reduce motor noise? The noise of the air motor comes from two aspects, 1 is the noise of mechanical rotation vibration. 2 is the impact sound of the airflow caused by the pressure drop at the exhaust port. (For example, the exhaust port of a motorcycle) The noise of an air motor mainly comes from the impact of the airflow. The noise reduction effect can be achieved by eliminating the impact of the airflow. Choosing a muffler with the same displacement according to the air consumption of the air motor can eliminate most of the noise. 1. The bearing rib coefficient needs to be designed according to the national standard, and the material cannot be stolen; 2. There should be no bumps in the manufacturing process, and the cleanliness is controlled to ensure the quality of the low-noise bearing; 3. The lubricating grease chooses silent motor bearing grease, such as synergy grease, etc.; 4. The installation process is correct, the inner ring of the bearing is pressed into the rotor, and the outer ring is loosely fitted; 5. The wave gasket is pre-tightened properly; 6. There is no knock during the installation process.
