Embodiment Construction
[0017] As shown in the figure, the present invention includes several turbine blades 2 and turbine disks 3 . A plurality of wedge-shaped grooves 7 are arranged at intervals on the outer side of the turbine disk 3 . Each wedge-shaped groove 7 is provided with a wedge-shaped key 6 with a gap therebetween. The outer side of each wedge key 6 is connected with a turbine blade 2 . The outer side of each turbine blade 2 is fixedly connected to the inner side of the turbine hoop 1 and is limited by it. The outside of the above-mentioned wedge key 6 can be connected with two turbine blades 2, that is, the two turbine blades 2 are an integrated structure connected to the wedge key 6. This integrated structure can not only enhance the structural strength of the turbine blade 2, but also make the new type of turbine Regardless of normal operation (turbine blades as power) or start-up (turbine disk as power), the turbine blades 2 and turbine hoop 1 and turbine disk 3 can be kept rotating...
