Worm- gear and worm can produce great heat at work
which makes them deformation
and the thermal stress is produced. Taking the worm- gear and worm of a single- stage worm reducer as the research object
the solid model is built by SolidWorks and imported to ANSYS WORKBENCH. The thermal analysis and the thermodynamic analysis are carried out. Through the parametric design method
the influence of the temperature on the maximum equivalent stress under the given structural load is analyzed
the changing curve of the maximum equivalent stress with the temperature is obtained.
