STUDY ON STEADY-STATE TEMPERATURE FIELD OF THE MESHING PAIR OF TWO-TOOTH DIFFERENCE SWING-ROD MOVABLE TOOTH DRIVE by YI YaLi, JI YaMeng, GUO Hui, JIN HeRong

“…Based on the basic theory of heat transfer and tribology,the calculation formulas of the friction heat flux density of meshing pair,the meshing tooth surface and the end face convective heat transfer coefficient with two-tooth difference swing-rod movable tooth drive are derived under the slip condition.A finite element model of the thermal analysis of the gear meshing pair is established,and the steady-state temperature field of the meshing pair under thermal balance state is calculated and analyzed by using the ANSYS finite element software.Combined with numerical simulation results,the influence of tooth profile design parameters on the temperature field is revealed.The result shows that:the steady-state temperature field of the meshing pair is determined collectively by the heat flux of the contact zone and the convection heat transfer coefficient of each surface.Because the temperature rise of sliding friction is larger,the maximum temperature appears in the center of the gear meshing face width of the center,the radius of the base circle radius has a great influence on the body temperature of the meshing surface,and the swing rod length is less affected.The research results lay the foundation for the study of the thermal deformation and thermal mechanical coupling characteristics of the meshing pair,so as to guide the dynamic design of the two-tooth difference swing-rod movable tooth drive.…”
