Analysis and research on teeth thermodynamic coupling contact of gear transmission system
Wang, Xigui,Wang, Yongmei,Zhao, Xuezeng,Li, Xinglin Techno-Press 2015 Coupled systems mechanics Vol.4 No.3
In the gear meshing process, gear temperature field concerns the meshing surface friction, the friction heat depends on the contact pressure, the contact pressure is affected by the elastic deformation of gears and the temperature field caused by the thermal deformation, so the temperature field, stress field and displacement field should be mutual coupling. It is necessary to consider in meshing gear pair in the operation process of thermodynamic coupling contact stress (TCCS) and thermodynamic coupling deformation (TCD), and based on thermodynamic coupling analysis (TCA) of gear teeth deformation.
Study on super-harmonic resonance for gear transmission based on teeth surface friction
Xigui Wang,Yongmei Wang,Xuezeng Zhao,Xinglin Li 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.11
Gear backlash and time-varying nonlinear meshing stiffness are the key design attributes of modern warship planetary gear transmission. The transmission prominent concern is teeth surface friction dynamics affect behavior and way. Therefore, the change of directionin meshing process, teeth surface friction will generate a larger oscillation, excitation response and energy consumption ways to affectdynamic characteristics of planetary gear transmission, which makes response range, dynamic behaviors more complex. Gear model andmulti scale equations for transmission are established, analyzing incentive role teeth surface friction when considering dynamic and staticload on influence law of gear resonance frequency response.
