The solid damping ring B includes an inner damping spring 1, an outer damping spring 2, and a fixed outer ring 3 arranged from the inside out. The inner damping spring 1 is suspended in the middle to form an inner damping cavity 4, and the outer damping spring 2 is recessed to form an inner damping groove 5.
