Nephogram of contact pressure distribution and contact state of low speed and heavy load gears

Figure 1 is the contact pressure diagram of the gear in the process of meshing, and the pressure distribution of the gear in the contact part can be observed.

It can be seen from Figure 1 that the contact pressure of the gear is large, and the maximum value is 1099.8 MPa.

As shown in Figure 2, we can observe the contact state in the process of gear meshing. The contact process is mainly in the near and sliding States, and there is no stickin state, which indicates that the gear runs well. When the setting torque is large, the adhesion phenomenon is easy to appear due to the tooth surface pressure effect, which is the reason for the tooth surface gluing of heavy-duty gears.

As shown in Figure 3, it can be seen that the maximum deformation of the gear is 49.28 mm.
