Experimental study of vibration reduction based on the flexible damping gear

Abstract

In order to reduce the vibration of gear transmission system, A new type of gear damping method: flexible damping gear was proposed in this study. a simplified flexible damping gear vibration isolation model was established, and a one-stage open spur gear vibration damping experimental bench was constructed. Based on the test bench, the following tests were carried out:1) flexible damping gear damping experiments; 2) flexible damping gear damping experiments under different torque; 3) flexible damping gear noise reduction experiments. The experimental results shown that the flexible damping gear can effectively reduce the vibration of the gear transmission system in a wide frequency band, and the highest vibration reduction can be achieved; with the increase of torque, the vibration suppression ability of flexible damping gear is also enhanced, and the average vibration reduction reaches 26.70%.
