The advantages of the integral spring design
Reduce the compressive stress on the friction plate. Reduce the total stiffness of the disc spring. During the calculation, it is necessary to control the MISES stress and the maximum principal stress of the diaphragm spring to avoid cracking; at the same time, the stiffness should be regulated according to the diaphragm spring displacement to ensure that the friction plate does not exceed the specified wear limit within the specified number of wear cycles, and the torque attenuation does not fall below the lower limit value.

Based on operating conditions（Limit Torque×Safety factor）Calculate the theoretical normal pressure required for the intermediate shaftσ；
Preliminary model design；
Calculate theoretical normal pressureσThe corresponding amount of propulsion and the stress level of each component;
The modified model gives a reasonable amount of thrust and controls the stress level of each component.
The torque limiter is proposed to adopt the integral disc spring type, which has the following characteristics: ① reducing the pressure stress on the friction plate; ② reducing the total stiffness of the disc spring.
The Mises stress and the maximum principal stress of the disc spring shall be controlled during calculation to prevent the disc spring from cracking. The stiffness of the disc spring shall be controlled according to its displacement, so that the torque attenuation of the friction plate does not exceed the lower line under the specified number of worn turns.
