-From the above data analysis, it can be seen that the friction generated by the sealing changes with the pressure and the contact surface. As the time when the four sealingings generate the maximum friction is different during the movement of the sealing, considering the extreme working conditions, the maximum friction generated by each sealing is combined as the basis for selecting the motor. The sum of the dynamic friction calculated according to tables 7 and 8 is 3306 N, the maximum friction obtained is substituted into Adams components as a known condition, and the external load is re-established to simulate the torque required by the motor, shown in Figure 17.
