[Abstract]:According to the theory of heat transfer, the calculation model of the temperature field of the meshing replica body of the real time steel ball precision transmission is established. The relative sliding velocity, maximum contact stress and friction coefficient of the meshing pair are derived according to the structural characteristics of the mechanism. A mathematical model of heat flux of meshing pair and convection heat transfer coefficient of cycloidal groove meshing surface, steel ball surface and meshing pair end surface are established. The temperature field of meshing replica body is calculated by finite element software, and the influence of mechanism design parameters on bulk temperature field is analyzed. The results show that the body temperature of the central disk is higher than that of the planetary disk, and the change of the parameters has obvious influence on the temperature field of the meshing replica. The results lay a theoretical foundation for the thermoelastic coupling analysis and reliability study of the meshing pair of real time steel ball precision transmission.
