CUT BODY OF REVOLUTION, FLYWHEEL ENERGY STORE AND METHOD FOR PRODUCING THE CUT BODY OF REVOLUTION

摘要

The invention relates to a body of revolution (1), a rotor (10) with such a body of revolution (1), a flywheel energy store (100) with at least one such rotor (10) and a method for producing this body of revolution (1) comprising a hollow first body (2), which is at least partially wound from a fibre composite material and has a first end (21) and a second end (22) and has an inner side (2i), directed towards the intended axis of rotation (R), and an opposite outer side (2a), wherein, at least in a cut region (23) adjacent to at least one of the ends (21, 22), the first or the second, the first body (2) tapers towards the respective end (21, 22) from the outer side (2a) to the inner side (2i) along a cut surface (24), and comprising a second body (3), which is wound from a second fibre composite material and comprises a circumferential layer (U2) of fibres (F2) with a fibre direction along a fibre angle (FW2) of over 80 degrees in relation to the intended axis of rotation (R) which are wound on the first body (2) in such a way that, at least seen perpendicularly in relation to the axis of rotation (R), the second body (3) covers at least the cut region (23) of the outer side (2a) of the first body (2).
