Abstract
In this research, three-dimensional simplified model for the planetary gear reducer of a certain large-scale shearer cutting unit is established by the use of UG NX5, and it is imported into ADAMS/View environment through the UG interface with ADAMS. While ANSYS is used to generate the flexible body of key parts such as sun gear, high-speed planet gear and low-speed planet gear, and then in ADAMS the flexible body is used to replace the corresponding parts of planetary reducer rigid body model, which aims to set up virtual rigid-flexible prototype model of planetary reducer. Finally, kinematics simulation was done. The simulation results show that the virtual prototype model of each component motion displays smooth without interference and the transmission ratio meets the design request. Meanwhile, the planetary gear mechanism design is proved to be very correct.
