Wherein the position of the detachment prevention structure 3 can be designed as desired. For example, the separation-preventing structure 3 may be a long-strip-shaped structure, and when the mandrel 1 rotates at a high speed, the width of the separation-preventing structure 3 in the extending direction of the mandrel 1 is smaller, so that the separation-preventing structure is more easily deformed under the action of centrifugal force, and the separation-preventing structure still maintains a contact state with the wheel disc 2 after the mandrel 1 is separated from the wheel disc 2.
According to the anti-separation flywheel structure provided by the invention, the outer side wall of the mandrel 1 is provided with the first groove 4 so as to form the anti-separation structure 3 on the mandrel 1.

For example, in the direction of the central line perpendicular to the axis of the mandrel 1, the two anti-separation structures 3 are symmetrically arranged one above the other, so that when the mandrel 1 rotates at a high speed, the deformation amounts of the two anti-separation structures 3 can be kept consistent, and the contact effect with the wheel disc 2 is improved.
In this embodiment, the end surface of the mandrel 1 is provided with a dynamic balance groove 6, for example, the dynamic balance groove 6 may be annular as a whole; the opening of the dynamic balance groove 6 gradually increases in a direction away from the end face of the mandrel 1. Preferably, the dynamic balance groove 6 may be provided at the bottom of the second groove 5. So set up, can make the dynamic balance piece more inseparable with being connected of dynamic balance groove 6, prevent that the dynamic balance piece from droing in the dynamic balance groove 6. In order to reduce stress concentration, the included angle position of the dynamic balance groove 6 may be chamfered.
