What's the difference between a rotating flywheel and a box flywheel?

The difference between flywheel and rotating flywheel lies in different disassembly methods, different structures and different vehicles. Different disassembly 1. The connection mode of flywheel and flywheel hub is the clamping of spline tower base and lock plate, and the toothed plate is detachable. Kaffee's gear discs are glued together one by one. There is a tower foundation in the middle, which can be erected one by one. The 9-speed consists of 9 flywheels. If a single flywheel is damaged, it can be replaced separately. 2. The connection between the rotating flywheel and the hub is threaded, and the toothed plate cannot be disassembled. Rotation is integrated. If the tooth is broken, it should be replaced. Different structures. The ratchet structure of the rotating flywheel is inside the flywheel, not on the hub. The single-speed flywheel of traditional bicycles also belongs to this structure. 2. The ratchet structure of the flywheel is located in the base of the hub. The flywheel has only a few teeth and has no complicated internal structure. Different vehicles use 1. Rotating flywheel is more common in single-speed cars, mountain bikes, old-fashioned variable-speed sports bicycles and low-end entry-level sports bicycles, such as 6-speed and 7-speed cars. 2. Because the structure is more stable, the weight is lighter and the smallest tooth can be smaller, the pincer flywheel has been widely used in the middle and high-end products of modern sports bicycles.
