That is, the second-stage reduction assembly of the preferred embodiment forms a space for the spring 4 to move through the cylinder flange 3 and the inner cylinder 5, and limits the spring 4 through the cylinder flange 3 and the inner cylinder 5.
According to a preferred embodiment, the inner cylinder 5 and the wheel-holder 6 are riveted, welded or bolted so that the pressing force of the process plate 11 and/or the spring force of the spring 4 can be transmitted between the inner cylinder 5 and the wheel-holder 6.

Similarly, when the interference amount is small, that is, the speed of the process plate 11 is slow or the number of the process plates is small, the instantaneous rolling friction force applied to the wheel 7 is also small, and at this time, the spring 4 is loosened, that is, the compressible amount of the spring 4 is increased, so that the optimal working condition is achieved.
