Verbundwerkstoffschwungrad

摘要

The device comprises a composite material flywheel (20) in which a plastic spoke member (22) reinforced with fiber having a modulus of elasticity lower than high-strength carbon fiber is joined to the inside of a high-strength carbon-fiber reinforced plastic ring (21) by press-fitting means. A taper bush (32) is fitted into a truncated conical shaft hole (31) formed in the central part of the spoke member (22) of the composite material flywheel (20); and spring means (34) are provided which force the taper bush (32) towards the spoke member (22). According to the invention, it is possible to absorb looseness with respect to a shaft (40) by means of a taper bush (32) and preventing whirling vibrations.
