When assembling the coupling, lubricant needs to be added to the contact surface between the spring and the fan-shaped block, and the fan-shaped block needs to be made of wear-resistant alloy material. The elastic element is made of 60Si2MnA spring steel, and the fatigue life is 2.3 times that of the traditional structure. Experimental data shows that it can withstand high-frequency impact loads at a speed of 2000r/min.
