Figure 6. Resistant section of the bushing

The stress state of the bushing is evaluated through FEM and takes into account the increase due to the notch. The results show that the maximum stress value is less than 400 N/mm 2 . Rocker arm. Due to the high stress intensification factor around the hole for the gripper housing, it is decided to modify the geometry of the pin. Figure 7 shows:

• results of FEM simulations, from which it can be seen that the maximum value of stress is around the hole (540 N/mm 2 ).
