The low-speed and heavy-duty gear assembly established by SolidWorks is exported to. Step format and imported into ANSYS Workbench. The geometric model is shown in Figure 1.
In workbench, the contact between the two gears is set as friction contact, and the friction coefficient is 0.15. Considering the deformation of the gear pair, the contact type is set as soft contact. The number of grids is 600000. The calculation time is 0.008 s when the pinion is the driving wheel and the speed of 10 RGS is applied, and the big gear is the driven wheel and the torque of 1000 n · m is applied, as shown in Figure 2.
