Abstract

Effect of dry friction damping ring (DFDR) on vibration characteristics of high speed large power density gear transmission (HSLPDGT) is studied. A coupling multi-body dynamic model of gear transmission with DFDR is built. In the model, the damping effect of DFDR on transmission, the varying meshing stiffness and transmission error are considered. A DFDR test system of gear transmission is developed. This DFDR test system has the highest input speed of 36000 r/min and oil lubrication. This model is verified by experiments. Effect structural parameter of DFDR on the vibration characteristics of gear transmission is studied. Results show that the DFDR has good damping characteristics of its decline of more than 20% for HSLPDGT. The gear transmission can get optimal damping effect by optimizing the DFDR outer diameter which is the amount of interference between DRDR and rim, thickness, width and other structural parameters.
