| 摘要 |
The present invention- relates to a vertical axis wind turbine for generating multi kilo watt power at rat&d wind speed by means of scaled up rotor assembly and plurality of generators. The vertical axis wind turbine comprises of a main gear means/ main driving means(2), a plurality of generators (1), a plurality of small gear means (6), a tower assembly (5) with plurality of poles, a control means, a lubricating means and a rotor assembly (3), rotatable supporting means/rolling means (9). In one embodiment shown in figure 1&1a, the main gear means/main driving means (2) configured to drive the plurality of small gear means (6) of generators for generating power, where rotatable supporting means/rolling means (9) act as a rotatable supporting assembly of the tower assembly (5). In another embodiment shown in figure 1b&1c, where each rotatable supporting means/rolling means (3) connected with each generator via shaft (11), and each contact region or tapered region of rotatable supporting means/rolling means (3) frictionally and rotatably engaged with tapered region/circular track (8) of the main gear means for generating power at rated wind speed. |
