The invention discloses a separated reaction flywheel body. The separated reaction flywheel body comprises a wheel rim, a wheel spoke, adjusting gaskets and a wheel hub, wherein the wheel rim is in coaxial clearance fit with the wheel spoke and connected with the wheel spoke through bolts; the wheel spoke and the wheel hub form an integrated structure through a welding process; the adjusting gaskets are nonmetal epoxy glass cloth plates, are clamped between the wheel spoke and the wheel rim and are used for adjusting damping coefficient of the whole wheel body and suppressing resonance amplification of the wheel body during working under a vibration environment. The wheel rim adopts an annular cylinder structure, and screw holes are formed in the internal side of the cylinder and the wheel rim can be coaxially connected with the wheel spoke through screws. The wheel rim is the far end of the wheel body in a radial direction and is made of a high-density stainless steel material so that the rotation inertia can be increased as much as possible. Central shallow holes are formed in the centers of two end surfaces of the wheel rim and used for reducing weight to realize dynamic balance. The separated reaction flywheel body disclosed by the invention is advantaged in that the machining process of the separated reaction flywheel body is simple, the structural strength/mass ratio and structural stiffness/mass ratio of the separated reaction flywheel body are high and the mass of the separated reaction flywheel body is obviously reduced; therefore, the axial load of the reaction flywheel is reduced and the reliability of the reaction flywheel is improved.
