双曲柄输入内平动齿轮传动的动态特性研究

Abstract

Aiming at the problem of large structure,severe vibration and high level of noise for the present external parallel moving gear transmission,a kind of internal parallel moving gears transmission with compact structure and complete balance is proposed.The elastic dynamics equation of the system is established by synthetically considering some factors.In the modeling process,the factors including the elastic deformation of all eccentric shafts,the elastic deformation of meshing gears,the elastic deformation of planetary bearing on eccentric shafts and supporting bearing on output shaft,and some dynamic characteristics such as the natural frequency,gear engaging force,bearing loads of system are derived according to the equation,and the results are analyzed.The basis on further optimizing the design of gear transmission,reducing vibration and improving mechanical properties is provided.
