Embodiment 1
[0027] see figure 1 , a starting device for a vertical-axis wind-driven generator, comprising a wind rotor main shaft 17 and a wind rotor, the wind rotor main shaft 17 is coaxially fixedly connected to the generator main shaft 14 through a coupling 13, and the wind wheel drives the wind rotor main shaft 17 to rotate, so that the generator Start, the wind rotor includes at least two generator blades 15, and evenly distributed around the wind rotor main shaft 17, the generator blades 15 are fixedly connected with the outer end of the blade support plate 16, when the generator blade 15 rotates, the blade support plate 16 The inner end transmits torque to the wind rotor main shaft 17, and then drives the wind rotor main shaft 17 to rotate. It is characterized in that: the inner end of the blade support plate 16 is fixed on the empty bearing seat 1, and the empty sleeve bearing seat 1 is installed through at least one bearing 4 On the wind wheel main shaft 17, the empty sleeve bear...
Embodiment 2
[0036] The technical solution of this embodiment is basically the same as that of Embodiment 1, especially in that:
[0037] In this embodiment, the connection between the outer friction discs 7, 11 and the wind wheel main shaft 17 is a spline. The splines have good guidance, can realize the dynamic connection between the mutually matched external friction discs 7, 11 and the wind wheel main shaft 17, and have the advantages of small stress concentration and strong load bearing capacity.
Embodiment 3
[0039] The technical solution of this embodiment is basically the same as that of Embodiment 1, especially in that:
[0040] In this example, see figure 2 and image 3 , In the present embodiment, there are 4 generator blades 15, and the slider mechanism of the pressing mechanism also includes 4 groups. Four generator blades 15 and four sets of slider mechanisms are used to form a vertical-axis wind turbine starting device, so that the device can capture wind energy as much as possible and at the same time optimize the structure of the device.
